I use the echo control binding. It was configured with thing/item files in Openhab2. and running since 2 years.
I use nextAlarm and textToSpeech (and lastVoiceCommand for debugging).
NextAlarm stopped working on Oct. 14. textToSpeech is all ok. lastVoiceCommand is also not working.
I did rebuild the Items with Openhab3 interface. Same result - no nextAlarm and no lastVoiceCommand; textToSpeech working.
