I think I have found the error: The config_flow crashed when it was searching for my KWL-type (it’s 40054-003).
I tried adding this number to the array in deviceList.py but this didn’t work.
When i comment out line 76 in EasyControls3Instance.py everything works like a charm. Except device-type is probably “None”.
Perhaps you could add 40054-003 for others…
Thanks a lot!
