I didn’t change anything on the Shelly, it was apparently configured correctly as relay. If I use the first screen of the device in Homey (with the slider) I get the 400 error message: “400: Onbekende fout, weet je zeker dat jet het juist IP adres hebt opgegeven en dat het Shelly apparaat op hetzelfde netwerk zit als Homey?”
If I use the second screen (with the 3 buttons, Up, Circle, Round), I don’t get an error message. But if I change a setting, I can hear the Shelly click and hear the ventilation change, it automatically resets after a few seconds.
In the previous version of either Homey or Shelly App. it added two devices, so I used these instructions to add flows for the ventilation to go either Low, Medium or High:
Changing the settings via the Shelly website itself works correctly, there it also shows the two separate channels.
