esphome mqtt switch example

2021/05/21

Its a good way to get started, however it only creates a skeleton file and you have to continue configuring the device manually to actually do anything anyway. I am fascinated with IoT and the point where software interacts with my physical world for example in the simplest form, a sensor programmed to turn a light bulb on when there is motion. Warn name less components when internal is not set to true. Default is 0 and will also be used to publishing messages. In this example, the topics are prefixed with home. This way you can track the changes youve made and can always go back to a working config. Under Config is a name (Unit Name:) set for your device (here its bathroom). stooge ws1 mqtt So considering all of the above I decided to accept the challenge and IoTed my air fresheners. should no longer be used and is deprecated. Everything with your device revolves around your devices YAML config file, including configuration, flashing, accessing logs, clearing out MQTT messages and more. Because we set a name for the reset switch, the reboot switch is visible and called Example Device Restart. To preserve battery life the ESP board goes into a deep sleep and wakes every few minutes to check if it needs to trigger the air freshener. Oh and Ill be able to get off to sleep without hearing that clicking noise and troubling myself with such crazy ideas like this. Thats a lot of things you get for just a little bit of YAML! Identifier of a device that routes messages between this device and Home Assistant. Optimistic mode can be forced, even if the state_topic is available. Can you #IoT an Airwick air freshener? To determine the devicess availability result of this template will be compared to payload_available and payload_not_available. sonoff basic esphome Only works through MQTT discovery and when unique_id is set. Konnected hardware can integrate with any platform that speaks MQTT by leveraging the ESPHome firmware. Weve all most likely been into a public restroom somewhere and had the automatic air freshener trigger and possibly even make us jump out of our skin when it does. Any question, i need control the 5 fans for my Rack home lab, is possible with ESPHOME?? After it reboots, you should see the new temperature and humidity inputs under devices in Home Assistant. Voice. ssd1331 esphome If not, you can tell esphome to tail the log by running esphome example.yaml logs. Its been a good eye opener for that. To provide me with the compute for this IoT project I turned to my trusted and favourite ESP32 NodeMcu board flashed with ESPHome. Enter your email address to subscribe to this blog and receive notifications of new posts by email. Crazy to you might not be crazy to someone else. It would be useful to replicate this and allow longer intervals between sprays. Thanks for sharing this, Chris well laid out and clear to follow. Therefore, specifying the exact device is good and can be helpful, but its not strictly necessary.

there is a fr esphome/feature-requests#600 you can upvote or propose other options, MQTT state/command topics not working on 'switch' component. If the published message should have the retain flag on or not. And well my house is smart so get with the programme! Hopefully you can see just how easy it is to add things to your ESP device and have them show up in Home Assistant. Problem-relevant YAML-configuration entries: Additional information and things you've tried: Seems like generated code is not calling MQTTSwitchComponent::setup() privacy statement.

Required fields are marked *. This switch triggers the air freshener to spray and is reset before ESPHome sends the device to sleep again. Once the device is running and connected to WiFi you can use OTA.

After the device reboots, the new reset button should automatically show up in Home Assistant as a device, under Configuration -> Devices under the name example. I wont go through all of the different automations I have created to work with my new-fangled smart IoT air fresheners but instead, Ill show you an example that in part is the most applicable for an air freshener. If two switches have the same unique ID, Home Assistant will raise an exception.

You would need a way to control the fans, probably via pulse-width modulation, and connect the controller to something like home assistant. Simply add this to the bottom of your YAML file. You make a rule in home assistant that increases and decreases the fan speeds when the temp reaches certain limits. Room based triggers. It checks which room Alexa was used in and then activates the air freshener a few times in that room. This way esphome will pick it up and apply that or you automatically. ESPHome on the Konnected Alarm Panel (ESP8266), ESPHome on the Konnected Alarm Panel Pro (ESP32). I THINK the .yaml in HA is sound, but not 100% about that either. So it just automatically published messages for states using the topic you set?

Follow me as I work with Microsoft 365 and help our customers achieve more. Usage example can be found in MQTT sensor documentation. Of course once you have all these devices its great to be able to use them in Home Assistant, but ultimately the point of it all is to automate the home. TBH Ive read this issue and I thought it was some Mqtt only issue Im closing. We will first define that pin as an output component using the ESP32 LEDC platform (supports PWM). This is entirely wasteful and not very smart. One thing I have noticed with Alexa routines is that Ive always had to keep the wake sentences short and not complex in order for them to be picked up by Alexa. true if no state_topic defined, else false. Operating environment/Installation (Hass.io/Docker/pip/etc. Thanks. Lets add those two things to our config! I went straight to Mosquito because I simply demand that nothing ever be easy. For those situations, Ill leave you with this. Where do you put that line exactly? Now I just need some time to try it out for myself. If youve already disconnected your ESP device from your computer, you can tail the log using MQTT. Now it just works when the toilet is flushed. If we toggle this light a few times, we can see the built-in LED on the ESP device fading in and out at the same time. Must not be used together with availability. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Sounds like you made the connections more robust and put more logic in the device so that it didnt do things unless there was a connection? Once you have a device to your liking, commit it to Git. Manually you can set pin 13 to high with mosquitto_pub or another MQTT tool: The configuration will look like the example below: The MQTT Switch integration was introduced in Home Assistant 0.7, The first one is for my WIFI and MQTT credentials (this is private and local, it is not pushed to GitHub), which are stored as variables in a file called secrets.yaml (store them in an Ansible vault, if you like). Sorry, your blog cannot share posts by email. If it does not have a name, it is considered 'internal' and the controls are not exposed to the front-end. Behind the scenes, there is a 3v motor which when powered, powers gearing that creates sufficient force to push down the nozzle on the can of air freshener. Otherwise, the initial state of the switch will be unknown. The example below shows a full configuration for a switch. By default, ESPHome will publish ON or OFF state payloads to an MQTT topic following this pattern: APP_NAME/COMPONENT_TYPE/COMPONENT_NAME/state, Example state topic: my_konnected/binary_sensor/zone_1/state, Switch zone types will respond to ON or OFF payloads published to a topic following this pattern: APP_NAME/COMPONENT_TYPE/COMPONENT_NAME/command, Example command topic: my_konnected/switch/siren/command, Did you find it helpful? Its as simple as adding this to the bottom of your YAML file. Your email address will not be published. But we could use motion in combination with when the air freshener last sprayed to ensure it only sprays every 30 minutes for example. The text was updated successfully, but these errors were encountered: I have the same issue with "light" topics, I also tried to add a switch but could not manage to get it working: The name to use when displaying this switch. Information about the device this switch is a part of to tie it into the device registry. You simply have to define your devices in YAML and run a single command to compile the firmware blob and flash a device. Getting started is pretty easy, just install esphome using pip. We then attach a light component using the monochromatic platform to that output component. I made a few alterations to the plastic insert in order for me to place the components inside. I am new to MQTT as well and found this helped me: I used a client called MQTT Explorer that I installed on my mac that I logged on to my MQTT server in HA. to your account.

I know I can do this in automations on either the HA side or the ESPHome side but whats the most foolproof/efficient way to do it? Once that worked I set up the sensors in configuration.yaml. I might have to try the built in broker if it auto-discovers that well. If I add mqtt_mqttswitchcomponent->setup(); These days a number of commercial products are been built using ESP8266 chips which we can flash, like Sonoff power modules, Xiaomi temperature sensors, Brilliant Smart power outlets and Mirabella Genio light bulbs (I use one of these under my stairs). The terminal should now be automatically tailing the log of the device (we enabled logger in the config). The MQTT topic to publish commands to change the switch state. It doesn't seem to work with me. some-topic/ and some-topic are different topics. Instead, I simplified the wake sentence to Alexa, its stinky and Alexa, it smells. As a final note, if you need to override something from PlatformIO, for example specifying a specific version of a dependency, you can do that by creating a modified platformio.ini file in your configs dir (copy from one of your build dirs and modify as needed). The payload that represents the on state. If my toilet is flushed and the bath or shower is in-use then that is a great indication the bathroom is in use. The kind and giving community of SharePoint and Office Dev Patterns and Practices (Pnp). Thanks for sharing, youve given me lots of ideas to try at my place. If you actually cabled this up and toggled the button in Home Assistant, the UI button turn on and you would hear the relay click on, then off, then the UI button would go back to the off state. The growth and learning opportunities are endless. For a check, you can use the command line tools mosquitto_pub shipped with mosquitto to send MQTT messages. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); 2022 Just another Linux geek. This started as a crazy idea after not being able to sleep one night and all I could hear was my air freshener clicking. There is pretty good documentation online though. This is used to show device topology in Home Assistant. sitting down, or standing up). Of course its probably a good idea to push your Git repo somewhere remote, perhaps even share your configs with others! I get huge joy from tinkering and exploring how things work but the real satisfaction comes from combining connected sensors, data, automation and machine learning and of course learning myself. I have since migrated most of my devices to ESPHome. The look and feel could not be compromised. YES. Loops, initialising and managing multiple inputs and outputs, reading and writing to I/O, PWM, functions and callbacks, connecting to WiFi and MQTT, hosting an AP, logging and more is taken care of for you. Sensors. Hey Brendan! You should see the device boot up and connect to your WiFi and MQTT server successfully. For now at least! Motion. In the living room, if the TV is on or the sofa is occupied then the room is in-use. So I fixed that. Otherwise, the switch will wait for state confirmation from the device (message from state_topic). If needed, pulling the pin down is easy, just set the default mode. The above example shows the new and modern way, When using MQTT, the channels are set with retain flag, so that the devices themselves and their last known states are not lost on reboots (you can disable this for testing). Its not just ESP modules that are supported. Rooms can be busy so triggering with each motion event would as wasteful as it spraying every 15 minutes now. The payload that represents on state. The type/class of the switch to set the icon in the frontend. I have some Sonoffs flashed with Tasmoda that work perfectly. Father, blogger, consultant, SharePoint, Azure, Office 365 and PowerShell specialist, troubleshooter, geek, home brewer and would be amateur chef. Internal components will not be exposed to the frontend (like Home Assistant). To determine the switchess state result of this template will be compared to state_on and state_off. Under ESPHome we can use the binary_sensor component with gpio platform. To provide me with additional data points that I can study, I added a counter that increments each time the unit is sprayed and a date sensor to store when the air freshener was last replaced. I ended up with a hand coded esp8266 app on mqtt that has multiple fail-safes. Once up, the devices support mDNS and unencrypted over the air updates (which is fine for my local network). In order to operate my air freshener automatically, I need something that I can programmatically control from Home Assistant. I also planned to use larger batteries but will need to 3d print a housing for that so for this prototype I housed the battery discretely on the back for ease of access and space reasons. In an ideal scenario, the MQTT device will have a state_topic to publish state changes. An MQTT topic subscribed to receive availability (online/offline) updates. There is even an addon for Home Assistant if you prefer using a graphical interface, but I like to do things on the command line. In the office, if my workstation is unlocked then I am likely working and the room is in-use. Hey Bob, yes, I definitely do want to replace it at some point and Ive also been looking at a few different platforms. Im keen to learn more! And yes, Ive IoTed my toilet! If set to any, payload_available must be received on at least one configured availability topic before the entity is marked as online. The payload that represents the off state. Including dealing safely with comms breakdowns. Well that requires some soldering or breadboard action, but what we can do easily is use the built-in LED on the device as a light and control it through Home Assistant. MQTT enables powerful integration with services like Node-RED, Homeseer, Domoticz and more. Spray interval. It is as simple as that. Read about what #Geek James does that isnt #SharePoint or #Office365 related, such as #Cooking, #Photography #HomeAutomation and #IoT. The payload that represents the unavailable state. Throughout my house, I have a large collection of sensors and in a truly connected world, these should be considered too. My friends wont freak out from the sound of the air freshener spraying nor think I think they smell!

A list of connections of the device to the outside world as a list of tuples [connection_type, connection_identifier]. If it really is that simple, I'm gonna be really happysad. In this mode, the switch will immediately change state after every command. on generated code, everything is working fine. Note that settings with !secret are referencing the variables in our secrets.yaml file, thus keeping the values out of our device config. A list of IDs that uniquely identify the device. Tried ESPHome to control sprinklers. This project is one that makes me feel on top of the world but also possibly one of my most craziest IoT projects. Learn more about Reddits use of cookies. Only specifying an id without a name will implicitly set this to true. I started by saying I would not compromise on the look and feel of the unit and hopefully the above demonstrates this. Lets do another example, a DHT22 temperature sensor connected to GPIO pin 16. Cheers. The ESP32 NodeMcu is powered from a battery and is connected to a relay. An ID that uniquely identifies this switch device.

One thing thats useful to know is that platform devices with the name property set in the config will appear in Home Assistant. Thanks for posting your experiences, Id love to know more. As before, after the device reboots again we should see the new PIR device appear in Home Assistant. Thanks to some @esphome_ + @home_assistant + some pretty magic! ): https://esphome.io/components/switch/index.html, Description of problem: Thats it! That is a gold mine.

However, the template switch which uses the relay has a name is and it has an action which causes the relay to be turned on and off, emulating a button press. For example a serial number. Here is the prototype IoT air freshener with another beast mode "Alexa, freshen up the house". I already had experience with Arduino, so I started experimenting with this and it worked quite well. The Airwick air freshener device is pretty discrete. Let me walk you through it. 'state_topic' and 'command_topic' MQTT topics doesn't work. Components are high level groups, like sensors, lights, switches, fans, etc. Remember we already added a switch component for the reboot platform? Cool, no worries Let me know if what you end up working on and if you need a hand. If the logic is still in HA, how did you solve this with custom code? After the device reboots, you should now be able to see the new Example LED automatically in Home Assistant. I then had a play with Micropython and really enjoyed it, but then I came across ESPHome and it blew me away. Try to enable it, if experiencing incorrect switch operation. This really could not have been made any easier and that is down to two great projects Home Assistant and ESPHome. Alarm state. Yep. My professors at the School of YouTube are letting me down on this one. on_press and on_release need another indent. The air freshener will last longer and because I converted the batteries I can recharge them. Help us improve this article with your feedback. My idea is put a thermometer , when pass the x temps up or down the power off fans. I got it mostly to see what it was like and whats possible in the world of home automation. Lets assume we have a relay connected up to a garage door openers push button (PB) input. Are you at all interested in replacing you Google bug^H^H^H Home? When the motor is no longer powered the gearing reverses from the return force of the nozzle of the can of compressed air freshener. Now we can re-run the compile and flash. The encoding of the payloads received and published messages. We can do all of this easily on the device with ESPHome and preset a single button to Home Assistant. There are other benefits to this madness. Flag which defines if the entity should be enabled when first added. The payload that represents off state. Valid entries are all, any, and latest. If youre using an MQTT server online you may want to use an ESP8266 device instead and enable TLS fingerprints for a more secure connection. Now need to add the new platform devices to that same section (dont create a second switch entry). Yes So while Ive made a few jokes in this article and had lots of fun along the way, the point I want you to take away is that ideas can become reality. OK, so rebooting the device is cute. Should be able to, so you want the LED to reflect the state of the relay? A configuration for a Controller for MQTT with the protocol OpenHAB MQTT is present and the entries (Controller Subscribe: and Controller Publish:) are adjusted to match your needs. When you were using ESPHome, did you have all of your logic in Home Assistant? I don't see any "publish.mqtt" in there. Press question mark to learn the rest of the keyboard shortcuts. The config file contains different sections with core settings. Pretty neat! The only difference is that Tasmoda has that nice little "setoption19 1" trick that pairs it up work HA immediately. For example, when the alarm is unarmed after a trip away the air fresheners could be sprayed to create a welcoming smell. I strongly recommend that if you havent explored Home Assistant, ESPHome or ESP32 NodeMcu for tinkering you give them a try. Now that you have the config file, we can compile it and flash the device (you might need to be in the dialout group). This allows me to wake the device, check the state of a MQTT topic. Adding a Yes, No, Cancel prompt to a PowerShell script, Replicate SharePoint Hub site navigation to other Hub sites, Working with SharePoint's Second Stage Recycle Bin in PowerShell, Event access management Power App with external barcode scanning for passes, Turn lights on and off when Windows 10 is locked or unlocked. For example the MAC address of a network interface: "connections": [["mac", "02:5b:26:a8:dc:12"]]. As Ive written about previously, the smart side of my home automation is managed by Home Assistant, which is an amazing, privacy focused open source platform. A link to the webpage that can manage the configuration of this device. The MQTT topic subscribed to receive state updates. Heres our new base config for an ESP32 device called example in a file called example.yaml which will connect to WiFi and MQTT. This time you can use OTA to flash the device via mDNS (but if its still connected via TTY then you can still use that instead). pic.twitter.com/mGy7wDUVE5. The relay is fired by pulling a GPIO pin high or low I assume? Basically I have a relay which is controlling a fan. Take opening a garage door for example, which only has one button to start and stop the motor in turn. Already on GitHub? Now we have a basic YAML file, lets add some components to make it do something more useful. We need to add a couple of devices to the ESP module and then expose only the button out to Home Assistant. Must not be used together with availability_topic. This is achieved using an MQTT topic. The other problem is if youre like me and find it hard to sleep sometimes the noise of them spraying throughout the night is annoying and likely lead to me saying to myself was trying to get to sleep I wonder if I can make these things smart. To do this, we add the reboot platform from the switch component. I do have a couple of proprietary home automation products, including LIFX globes and Google Home. Now that we have our base secrets file, we can create our first device config! Nice one Chris, cool post. Again, compile and flash the firmware with esphome. I planned to use a smaller ESP32 dev board but for this prototype, Ive opted to use the standard board for ease of access. The mqtt switch platform lets you control your MQTT enabled switches. You signed in with another tab or window.

Ive likely fallen asleep as this stage and forgotten about the crazy idea, but clearly this one time I didnt, so here I am writing about how to IoT Airwick air fresheners. For example, for this I started with Alexa, it is stinky in here but her response would be Sorry, I dont know that one. Sign in That particular air freshener is triggered when my IoT toilet is flushed and as automations go is the coolest toilet air freshener automation you will likely to ever see! Lets consider a smart air freshener and how it would work if it wasnt triggered by a manually. the mqtt/state is triggered when the button is toggled by web server, but it seems not listening on mqtt/command. This is how you can link multiple components together on the device, then present a single device to Home Assistant (like garage remote below).

In general its not advised to store any form of credentials on external services such as github. If my house alarm is armed then that is a good sign Im not home so the air fresheners shouldnt work. This project was no exception. Finally, we set the class of the device to motion which will set the appropriate icon in Home Assistant. Lets create the Git repo and link to the secrets file and ignore things like the builds directory (where builds will go!). Post was not sent - check your email addresses! Same problem here (with v1.14.4). In 10 lines of configuration, I was able to create a switch that operates that relay and thats it. There is no further configuration needed as the GPIOs can be controlled with MQTT directly. Have a question about this project? This allows you to operate your switch manually: Assuming that you have flashed your ESP8266 unit with ESPEasy. Used when value that represents on state in the state_topic is different from value that should be sent to the command_topic to turn the device on. You can leave some of these settings out, such as api, which will disable that feature on the device (esphome is required). This relay allows a circuit to open and closes which then activates the motor and gearing inside the air freshener. We use cookies on our websites for a number of purposes, including analytics and performance, functionality and advertising. This prevents the gearing from forcing the aerosol can to spray continuously and it runs out of gear. Although built on similar SOC, different devices break out different pins and can have different flashing requirements. (If you want to give it a try, you can run the command esphome example.yaml wizard which will create an example.yaml file.). ESPHome is smart in making use of PlatformIO underneath, but its beauty lies in the way it abstracts away the complexities of programming for embedded devices.

This will compile the firmware in the specified build dir (./builds/example) and prompt you to flash the device. We read the GPIO pin and can tell when motion is detected because the control pin voltage is set to high. Those without will be only local to the device and just have an id. It does hinder the auto discovery capability, but it increases the hip factor. Lack/use of quote marks on the topic names? Check your indentation. The hardware is sound. and it's used by. A simple MQTT connection only requires a broker address (and probably username/password). Its as simple as adding this to the bottom of your YAML file.

These units typically run on a schedule and spray some kind of air freshener into the room. Of course, you will need a real physical ESP device of some description. The correct topic names are shown at boot: But it does not listen (e.g. Let your mind run away and be creative. For me, the data is as much fun to play with and analyse as the tinkering with all the hardware. ESPHome not recommended for critical apps. In fact, Home Assistant auto-discovers ESPHome devices so the switch I defined in my configuration is immediately available to use. ESPHome provides the ability to do this through a web UI, MQTT or in my case through integration with Home Assistant. When availability is configured, this controls the conditions needed to set the entity to available. For example, two of the different platforms under the light component are rgbw and neopixelbus. The MQTT topic subscribed to receive availability (online/offline) updates. Thats beyond the scope of this particular post though, as I really wanted to introduce ESPHome and show how you can easily manage devices and integrate them with Home Assistant. Do you know how you would go about tying the fate/state of two switches together? I ran it through codebeautify.org, and it returned with " Error : You cannot define a mapping item when in a sequence". In an inclusive world, voice assistants are increasingly used to perform tasks that ordinarily might have been out of reach for some people. Once I also specify a name in my config, everything works fine. This could be taken a step further and a routine could be used to activate all the air fresheners like Alexa, freshen up the house for those moments when you have someone special coming over! I don't feel like this is an exotic case, but I have scoured the internet looking for an example .yaml and can't find anything. Can be either an HTTP or HTTPS link. I could be wrong, but I don't think that the default ESPHome integration (which I have got to work) uses MQTT. So, I think ultimately its easier to just create and manage your own files, which well do below. The entity also needs a name property. Your email address will not be published. By clicking Sign up for GitHub, you agree to our terms of service and ESPHome automatically looks for this file when compiling firmware for a device and will use those variables. With Konnected + ESPHome you can combine Konnected's high-quality hardware with the power and flexibility of local and secure MQTT communication. Set to "" to disable decoding of incoming payload. Defines a template to extract devices availability from the availability_topic. Yes, you could do that, either with a single ESP and supporting boards where you put all the logic into it, or using something like home assistant. There are many other things you can do with ESPHome, but this is just a taste. The payload that represents the available state. Then you have a temp sensor which also reports to home assistant. The old format that places configurations under the switch platform key Join me as I continue to build, work and play on this fantastic product where I enable, support and help customer create digital workplaces and #ModernIntranets. Found that any breakdown in wifi between ha server and ESPHome widget left confusion between ha and widget state if/when comms was re-established. ESPHome Binary Sensors, Switches & Sensor Configuration. Defines a template to extract the JSON dictionary from messages received on the json_attributes_topic. This uses a custom component for Home Assistant called alexa_media_player.
