I installed insteon-mqtt & mosquitto as add-ons in HA Supervised running in Debian VM on a Mac Mini.
They appear to be communicating, but I do see one error when Insteon-mqtt starts:
The WebSocket transport is not available, you must install a WebSocket server that is compatible with your async mode to enable it. See the documentation for details. (further occurrences of this error will be logged with level INFO)
Whatever I try, I can’t seem to get a command from Insteon-mqtt to work. It seems like they run up against a brick wall and timeout. Is the error above causing this?
