esphome mqtt switch example

Let your mind run away and be creative. I could be wrong, but I don't think that the default ESPHome integration (which I have got to work) uses MQTT. 'state_topic' and 'command_topic' MQTT topics doesn't work. wfusb xy relay But we could use motion in combination with when the air freshener last sprayed to ensure it only sprays every 30 minutes for example. Once the device is running and connected to WiFi you can use OTA. Of course, you will need a real physical ESP device of some description. 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? I am trying to make a chair sensor for use in Home Assistant to dim the lights in the evening when you sit down, and pause Plex when you stand up using a seat pad pressure sensor. Now we have a basic YAML file, lets add some components to make it do something more useful. esphome In the living room, if the TV is on or the sofa is occupied then the room is in-use. Lets create the Git repo and link to the secrets file and ignore things like the builds directory (where builds will go!). I then had a play with Micropython and really enjoyed it, but then I came across ESPHome and it blew me away. Flag that defines if switch works in optimistic mode. This relay allows a circuit to open and closes which then activates the motor and gearing inside the air freshener. 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 have been researching various open-source speech-to-text projects and want to try some out, as in all speech processing taking place in-house. Ill be able to work out when the spray needs replacing from the data. on generated code, everything is working fine. 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. The run command actually does a number of things, include sanity check, compile, flash and tail the log. I strongly recommend that if you havent explored Home Assistant, ESPHome or ESP32 NodeMcu for tinkering you give them a try. Same problem here (with v1.14.4). If it does not have a name, it is considered 'internal' and the controls are not exposed to the front-end. So I fixed that. For example, for this I started with Alexa, it is stinky in here but her response would be Sorry, I dont know that one. It contains a can of the air freshener of your choosing and two AA batteries. Everything with your device revolves around your devices YAML config file, including configuration, flashing, accessing logs, clearing out MQTT messages and more. To provide me with the compute for this IoT project I turned to my trusted and favourite ESP32 NodeMcu board flashed with ESPHome. The ESP32 NodeMcu is powered from a battery and is connected to a relay. some-topic/ and some-topic are different topics. I created an MQTT switch that is enabled when a binary sensor is on. Thanks. Otherwise, the switch will wait for state confirmation from the device (message from state_topic). 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. Only works through MQTT discovery and when unique_id is set. Its much safer to start your IoT device with no wifi secret and start it as AP and register it on your wifi once. Then an automation in Home Assistant is triggered. Identifier of a device that routes messages between this device and Home Assistant. As mentioned previously, there are many devices we can easily add to a single board like relays, PIR sensors, temperature and humidity sensors, reed switches and more. An ID that uniquely identifies this switch device. All information provided and opinions expressed on this website, in no way reflect the opinions of my employer, clients Im working or associated with, they are completely and solely my own personal opinion. 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). Yes The brain of my house Home Assistant handles all the integration with ESPHome, other sensors and the home automation logic. pic.twitter.com/mGy7wDUVE5. To turn the switch on and off you need an interface. It would be useful to replicate this and allow longer intervals between sprays. Why these intervals I dont know but Im sure Airwick have their reason. The config file contains different sections with core settings. Sorry we couldn't be helpful. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. For this post though, I will use one of my MH-ET Live ESP32Minikit devices as an example, which has the device name of mhetesp32minikit. If the published message should have the retain flag on or not. ESPHome on the Konnected Alarm Panel (ESP8266), ESPHome on the Konnected Alarm Panel Pro (ESP32). My bathroom air freshener. This allows me to wake the device, check the state of a MQTT topic. The example below shows a full configuration for a switch. The initial state is set to False / off in optimistic mode. 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). 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. Must not be used together with availability. If set to any, payload_available must be received on at least one configured availability topic before the entity is marked as online. For now at least! 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. Try to enable it, if experiencing incorrect switch operation. 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, Konnected hardware can integrate with any platform that speaks MQTT by leveraging the ESPHome firmware. The only difference is that Tasmoda has that nice little "setoption19 1" trick that pairs it up work HA immediately. The kind and giving community of SharePoint and Office Dev Patterns and Practices (Pnp). Pretty neat! If the logic is still in HA, how did you solve this with custom code? 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. By clicking Sign up for GitHub, you agree to our terms of service and If I add Cool tutorial! The unit provides some control over the frequency the air freshener sprays but this is limited to 9, 18 and 36-minute intervals. And yes, Ive IoTed my toilet! For example, when the alarm is unarmed after a trip away the air fresheners could be sprayed to create a welcoming smell. Required fields are marked *. Even if youre using a private repository, theres still potential for leaking them or getting them stolen. TBH Ive read this issue and I thought it was some Mqtt only issue Im closing. Cool, no worries Let me know if what you end up working on and if you need a hand. When combined with Home Assistant, new devices are automatically discovered and appear in the web interface. Only specifying an id without a name will implicitly set this to true. 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). 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. I moved a bunch of stuff I had running in podman containers over to k8s deployments instead bitwarden, hass, unifi, awx, etc. You can leave some of these settings out, such as api, which will disable that feature on the device (esphome is required). Press J to jump to the feed. Can be either an HTTP or HTTPS link. Defines a template to extract devices state from the state_topic. You should see the device boot up and connect to your WiFi and MQTT server successfully. Sometimes though, you need to make things a little more tricky. #SharingIsCaring. There is no further configuration needed as the GPIOs can be controlled with MQTT directly. Thanks! Including dealing safely with comms breakdowns. Lets add those two things to our config! 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. When a state_topic is not available, the switch will work in optimistic mode. This will compile the firmware in the specified build dir (./builds/example) and prompt you to flash the device. So, I think ultimately its easier to just create and manage your own files, which well do below. sitting down, or standing up). 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. If set to all, payload_available must be received on all configured availability topics before the entity is marked as online. I should also mention that MQTT is not required, devices can also use the Home Assistant API and if you dont use MQTT those variables can be ignored (or you can leave them out). Those without will be only local to the device and just have an id. Oh and Ill be able to get off to sleep without hearing that clicking noise and troubling myself with such crazy ideas like this. As this is a new device, an over the air update will not work yet, so youll need to select the TTY device. Its as simple as adding this to the bottom of your YAML file. Lets do another example, a DHT22 temperature sensor connected to GPIO pin 16. In this mode, the switch will immediately change state after every command. In this example, the topics are prefixed with home. I went straight to Mosquito because I simply demand that nothing ever be easy. I hate to ask someone to write my code for me, but I'm taking stabs in the dark here. This project is one that makes me feel on top of the world but also possibly one of my most craziest IoT projects. For a check, you can use the command line tools mosquitto_pub shipped with mosquitto to send MQTT messages. After the device reboots, you should now be able to see the new Example LED automatically in Home Assistant. ESPHome provides the ability to do this through a web UI, MQTT or in my case through integration with Home Assistant. If you want to make this visible on the main Overview dashboard, you can do so by selecting ADD TO LOVELACE. privacy statement. I already had experience with Arduino, so I started experimenting with this and it worked quite well. First thing we can do is add a software switch which will let us reboot the device from Home Assistant (or by publishing manually to MQTT or API). Here is the prototype IoT air freshener with another beast mode "Alexa, freshen up the house". 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. this is the previous/old example: A list of MQTT topics subscribed to receive availability (online/offline) updates. Spray interval. These are just local Git repositories so it doesnt mean they are pushed to GitHub, nevertheless Ive added a note saying that the Git repo which holds the secrets is, private and local, it is not pushed to GitHub. Thanks! It doesn't seem to work with me. 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. Nice one Chris, cool post. We use cookies on our websites for a number of purposes, including analytics and performance, functionality and advertising. Are you at all interested in replacing you Google bug^H^H^H Home? 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: In fact, Home Assistant auto-discovers ESPHome devices so the switch I defined in my configuration is immediately available to use. If specified, will be used for both comparing to the value in the state_topic (see value_template and state_off for details) and sending as off command to the command_topic. 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. No, Modified on: Sat, 6 Mar, 2021 at 7:03 PM. Father, blogger, consultant, SharePoint, Azure, Office 365 and PowerShell specialist, troubleshooter, geek, home brewer and would be amateur chef. In 10 lines of configuration, I was able to create a switch that operates that relay and thats it. Suggest an area if the device isnt in one yet. 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. A link to the webpage that can manage the configuration of this device. Once up, the devices support mDNS and unencrypted over the air updates (which is fine for my local network). mqtt_mqttswitchcomponent->setup(); The hardware is sound. My friends wont freak out from the sound of the air freshener spraying nor think I think they smell! Components are high level groups, like sensors, lights, switches, fans, etc. So you want to make sure those two states match? Each component is divided into platforms which is where different devices of that type are supported. There are other benefits to this madness. Used when value that represents off state in the state_topic is different from value that should be sent to the command_topic to turn the device off. Used instead of name for automatic generation of entity_id. If two switches have the same unique ID, Home Assistant will raise an exception. Of course its probably a good idea to push your Git repo somewhere remote, perhaps even share your configs with others! The MQTT topic subscribed to receive state updates. Now that you have the config file, we can compile it and flash the device (you might need to be in the dialout group). For those situations, Ill leave you with this. Defines a template to extract devices availability from the availability_topic. Your email address will not be published. Again, compile and flash the firmware with esphome. OK, so rebooting the device is cute. Great! 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. 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. For hass, its nothing too complex, just a deployment, replicaset and service in a namespace with an ingress. (If you want to give it a try, you can run the command esphome example.yaml wizard which will create an example.yaml file.). Defines a template to extract the JSON dictionary from messages received on the json_attributes_topic. This switch triggers the air freshener to spray and is reset before ESPHome sends the device to sleep again. Crazy to you might not be crazy to someone else. Its not just ESP modules that are supported. Under ESPHome we can use the binary_sensor component with gpio platform. Have a question about this project? The type/class of the switch to set the icon in the frontend. Thats it! 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? Take opening a garage door for example, which only has one button to start and stop the motor in turn. To do this, we add the reboot platform from the switch component. Read about what #Geek James does that isnt #SharePoint or #Office365 related, such as #Cooking, #Photography #HomeAutomation and #IoT. In an inclusive world, voice assistants are increasingly used to perform tasks that ordinarily might have been out of reach for some people. If youve already disconnected your ESP device from your computer, you can tail the log using MQTT. You simply have to define your devices in YAML and run a single command to compile the firmware blob and flash a device. If not, you can tell esphome to tail the log by running esphome example.yaml logs. I might have to try the built in broker if it auto-discovers that well. Its as simple as adding this to the bottom of your YAML file. In general its not advised to store any form of credentials on external services such as github. This allows you to operate your switch manually: Assuming that you have flashed your ESP8266 unit with ESPEasy. The old format that places configurations under the switch platform key I have some Sonoffs flashed with Tasmoda that work perfectly. Thanks for sharing this, Chris well laid out and clear to follow. A simple MQTT connection only requires a broker address (and probably username/password). 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. Some are even a little smarter and trigger when there is motion in the room. Go ahead and toggle the switch while still tailing the log of the device and you should see it restart. I got it mostly to see what it was like and whats possible in the world of home automation. To determine the switchess state result of this template will be compared to state_on and state_off. That is a gold mine. should no longer be used and is deprecated. Certainly, if ha had turned sprinklers on, expect an exorbitant water bill. For me, the data is as much fun to play with and analyse as the tinkering with all the hardware. Now need to add the new platform devices to that same section (dont create a second switch entry). The payload that represents the unavailable state. The correct topic names are shown at boot: But it does not listen (e.g. Thanks to some @esphome_ + @home_assistant + some pretty magic! true if no state_topic defined, else false. These units typically run on a schedule and spray some kind of air freshener into the room. The MQTT topic subscribed to receive a JSON dictionary payload and then set as sensor attributes. Thats a lot of things you get for just a little bit of YAML! But with all these crazy ideas I wasnt going to compromise on the aesthetics. In an ideal scenario, the MQTT device will have a state_topic to publish state changes. Finally, we set the class of the device to motion which will set the appropriate icon in Home Assistant. The maximum QoS level of the state topic. To determine the devicess availability result of this template will be compared to payload_available and payload_not_available. It is as simple as that. Follow me as I work with Microsoft 365 and help our customers achieve more. 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. The payload that represents on state. Lets create the Git repo and secrets file, replacing the details below with your own. This is entirely wasteful and not very smart. This really could not have been made any easier and that is down to two great projects Home Assistant and ESPHome. In fact, no programming is necessary! A PIR sensor connects to ground and 3-5V, with data connecting to a GPIO pin (lets use 34 in the example). Thanks for posting your experiences, Id love to know more. Information about the device this switch is a part of to tie it into the device registry. 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. Now I just need some time to try it out for myself. It checks which room Alexa was used in and then activates the air freshener a few times in that room. Wow I had no idea we had this easy a framework for HomeAssistant to make ESP32 devices work easier. The name to use when displaying this switch. MQTT enables powerful integration with services like Node-RED, Homeseer, Domoticz and more. As before, after the device reboots again we should see the new PIR device appear in Home Assistant. A MQTT device can reset the current state to unknown using a None payload. Room based triggers. Yep. Tried ESPHome to control sprinklers. 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. 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). Cheers. Notice the red plunger gear is only two-thirds round. I planned to use a smaller ESP32 dev board but for this prototype, Ive opted to use the standard board for ease of access. Should be able to, so you want the LED to reflect the state of the relay? Remember we already added a switch component for the reboot platform? Help us improve this article with your feedback. We all know there can be those moments when a little fresh air is most welcome. The encoding of the payloads received and published messages. This started as a crazy idea after not being able to sleep one night and all I could hear was my air freshener clicking. The relay is fired by pulling a GPIO pin high or low I assume? Otherwise, the initial state of the switch will be unknown. Lack/use of quote marks on the topic names? 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). Im keen to learn more! 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.
