I know with the 2.0 modules the raise and lower for volume on generic devices isn't working for us. It does work on the older modules (alexa raise kitchen music). We are able to set the volume to a level with the set alexa command (alexa set kitchen music 20%). I only put the 2.0 on one site so far but will try and test through tstat commands and also see if raise and lower still work for the lights.?
