Thanks to the work of github member “Hypfer”, it’s now possible to use the cheap IKEA PM2.5 sensors as a MQTT source. I set it up with my homey as follows: - Applied the hardware mod with a Wemos D1 Mini - Put the supplied sketch onto the D1. - Installed MQTT broker and MQTT client on Homey. - Set up MQTT on the D1 - Create a virtual device on Homey (type: sensor, air quality) by using the [Virtual Devices app](https://homey.app/nl-nl/app/com.arjankranenburg.virtual/Virtuele-Apparaten/) - Add a flow to homey: " IF MQTT Client Trigger when a message is received on “/home/data/pm25/1” THEN PM2.5 (virtual sensor) Set the value of a virtual sensor measure\_pm25 to “message recived via topic” It will work like a charm 😄 ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/6/661bd2ef740265911d9f309efdd01509e4826c08.png) And it’s pretty cheap for a smart sensor of this kind.

Awesome find! How often does the Vindriktning update PM readings? ---

A couple of times every minute. ---

Did you modify the .ino file or did you just uploaded it to the Wemos? ---

I didn’t modify anything, just uploaded it. Configuration is done through the web portal. ---

I have done al the steps as mentioned in the first post. Unfortunatly I don’t receive anything from the sensor. In the developer tools I see that it is pushing data to the pm25 sensor. But still nothing is received… ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/c/cc98334ff24064723686cf86e26cd5a64447fbd7.png) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/b/3bfea95ab2f3ed616a419b158dee7d273b49b0ba.png) ---

I’m fairly sure your sensor data isn’t being published to `/home/data/pm25/1` but to `esp8266-vindriktning-particle-sensor/VINDRIKTNING-XXXX/state` ---

That did the trick (first time MQTT is a little bit a search ☹ ). Now i’m receiving data: {“pm25”:9,“wifi”:{“ssid”:“ssid\_name”,“ip”:“192.168.1.122”,“rssi”:-58}} ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/8/98bd2d5f6e1e856d453e8f916ec63092769699ff.png)
