MMM-xiaomi - Temperature and Humidity from your smarthome
- 
 Am sorry, it was my mistake. I did not checked my config.js. Out of nowhere there was again devices:instead of rooms:Thank you for your help! I’ve tried to get the icon for the open state of the window sensors working this way: 
 The first ID is the temperature sensor, the second one the window sensors:{ module: 'MMM-xiaomi', position: 'bottom_left', header: 'Temperatur / Feuchtigkeit', // This is optional config: { gatewayIP: '192.168.2.160', gatewayToken: '6ebf9b84e5c615c09268166a99b95f0a', showWindow: true, rooms: [ { name: 'Wohnzimmer', sortOrder: 30, devices : ['158d00015736a8', '158d000119fcb2'] }, ] } },and this way: { module: 'MMM-xiaomi', position: 'bottom_left', header: 'Temperatur / Feuchtigkeit', // This is optional config: { gatewayIP: '192.168.2.160', gatewayToken: '6ebf9b84e5c615c09268166a99b95f0a', rooms: [ { name: 'Wohnzimmer', sortOrder: 30, showWindow: true, devices : ['158d00015736a8', '158d000119fcb2'] }, ] } },Both times MM did not started because of errors in the config. How is the right way to get this solved? 
- 
 Your first config is correct, I guess you might have made an error somewhere else in your config, I could run your config successfully. 
- 
 Hmm… I must have had a typo somewhere. Now the config is working for me as well but still no icon. this is how it works so far: { module: 'MMM-xiaomi', position: 'bottom_left', header: 'Temperatur / Feuchtigkeit', // This is optional config: { gatewayIP: '192.168.2.160', gatewayToken: '6ebf9b84e5c615c09268166a99b95f0a', showWindow: true, rooms: [ { name: 'Wohnzimmer', sortOrder: 30, devices : ['158d00015736a8', '158d000119fcb2'] }, ] // See 'Configuration options' for more information. } },This is what I get:  mm out: > magicmirror@2.1.3 start /home/pi/MagicMirror > sh run-start.sh Starting MagicMirror: v2.1.3 Loading config ...

 Note that the icon only appears on open windows - its a white star. If the window is closed you will not see any icon. Also I have noticed that the open state is not really reliable, need to check with miio why there are so many false states sent.

 @mirko3000 said in MMM-xiaomi - Temperature and Humidity from your smarthome: Note that the icon only appears on open windows - its a white star. That was the point that i’ve missed! when I open the window, the white star appears impatiently! I love this module! Thank you for your work!

 Don’t forget to update the npm packages (miio), there is a bugfix which caused wrong close events of the windows. Either ‘npm update’ in the MMM-xiaomi folder, or delete the “node_modules” folder and simply execute ‘npm install’ again.

 My new sensors are arrived… I love it! Great work!  Which lights are supported? 
- 
 Check your devices here: 
 https://github.com/aholstenson/miio/blob/master/docs/devices/README.md#models-by-nameAs you see not all Yeelights are supported, others are untested. My module retrieves all devices of type ‘light’, so it might work for all of them.

 hi, finally my gateway arrived today. Great. it is working after a little struggeling to get the correct App to initally configure the stuff. I added 4 temp/humidity sensors and i am wondering how to see in the miio discovery whick one is in which room? 
 Any chance to get that ?
 I the app itself i sadly can’t see the IDs of the sensors?How did you figured this out?
