ERROR MQTT: Unable to decode MQTT message

[amaisano]

Problem/Motivation

Using ControllerX, my app settings for the IKEA Symfonisk dial no longer work. Each time I dial it the AppDaemon log is filled with these errors:

2023-09-24 18:12:34.999330 ERROR MQTT: Unable to decode MQTT message, with Traceback: Traceback (most recent call last): File "/usr/lib/python3.11/site-packages/appdaemon/plugins/mqtt/mqttplugin.py", line 271, in mqtt_on_message payload = payload.decode() ^^^^^^^^^^^^^^^^ UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

My other Z2M integration settings and actions work fine (I have several IKEA switches).

Expected behavior

Interacting with the E1744 should perform the HA actions configured in app.yaml. See https://xaviml.github.io/controllerx/controllers/E1744/?h=e1744#zigbee2mqtt-light

Actual behavior

Errors occur above. Other devices continue to work as configured.

Steps to reproduce

See above config and use E1744 hardware. Currently the device is on firmware 587683377 (not the most currently - have not been able to every update this device but it works fine before the most recent HA Update 2023.9.0).

Worth noting a small change has been added to app daemon (but has been unreleased) that will make the debugging of this issue in your environment easier:

Closing this on this end, as this is an issue with AppDaemon, not the add-on itself.
