[APP][Pro] Mitsubishi WF-RAC - Cooling, heating and ventilation

What makes you think that Homey is “kicked out” as a controlling device?
I’ve never had that problem before tbh.

How long did you wait before you re-create the devices?
My connections go down also sometimes, but they will restore eventually.
Did you also try to restart the app in Homey?

Furthermore, I can see a LOT of these lines in your error report (at least every 5 minutes for 1 specific airco):

[Device:xxxxxxx] Last seen changed 192.168.1.68:51443

You need to check your network setup. It always gets the same IP address, but that is looking weird to me.

And every 30 minutes you get this error (for 1 specific airco’s):
[Device:xxxxxxx] [Sync] Error: error.connection

So, 1 airco is “rediscovered” all the time, and 2/3 don’t, but have connection errors.

I found this interesting topic which proves that WF-RAC devices will terminate the network connection to the router every hour!!
