I am running Picroft on Pi3B+ with ReSpeaker 4 Mic Array and Precise listener. I am really struggling with the Wake Word detection. It was working initially, but not extremely. During one of my debugging sessions I spoke the wake word 5+ times and since then Mycroft stopped responding to wake words at all.
The micrphone and the language processing seems to be working as I can set timers if I initiate communication via CLI. This looks similar to the issue described here.
