I run openhab 2.4 on a Raspberry 3+, openhabian distribution.
Starting yesterday (it worked fine for about a year or so), my echo dot and echo show stopped working with my openhab hue emulation. When I tried to use one of the voice commands, Alexa replied that the device does not respond. The echo control binding works fine.
Here is what I tried so far:
I cleared the list of devices through the alexa web interface, set the hue emulation via Paper UI in pairing mode and searched for devices again - the devices were found again, but no change in the reaction of Alexa to the voice commands
I reinstalled the hue emulation and restarted openhab – no change
I reset my echo dot (this had helped in the past when I had similar problems)
I deleted the devices from Alexa through the web interface one by one (the first time, I deleted them all at once). This time, when I tried to pair them again, Alexa did not find any of the devices that should be exposed by the hue emulation at all
Does anybody have a clue, what could have happened?
