Insteon-MQTT commands timeout (no response)

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?

Hi. I just started on insteon-mqtt and have exactly the same problem. Did you find a solution?

Thank you.

I finally got Insteon-Mqtt to work. It didn’t seem to be the websocket error. In my case I had to set the modem ID very explicitly (not sure why the “right” way didn’t work, and I’ve been working through too many other issues!). In my case, it was:

# PLM Modem option (Serial or USB)
port: /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_AK05Z7PL-if00-port0

Feel free to ask - insteon-mqtt is great, but there are a lot of little gotchas not immediately apparent to us noobies.
