@Michel_Bos Thank you for your welcome words.
I managed the next day to connect with Google Home for some reason. But now I have a different problem that a number of Hue devices go offline in Homey after a number of hours or days with the message:
“Matter device was set to factory settings or was removed externally from Homey [originally in Dutch]”
I see no other way than to restart Homey as there is no app to restart nor does Homey have an option in the tools site.
I found this thread, but there seems to be no active thread on this?
I am not amused.
