CRITICAL MQTT: There was an error while processing an MQTT message: <class 'IndexError'> list index out of range

[Shaun-Harrison]

Hello

First time using appdaemon and monitor together, currently running the old monitor as a service on rpi's around the house, so getting myself up to speed

I've stopped all the current monitor services so that I can get this working on my RPI4 first before looking at using the other RPI's around the house

So this is my appdaemon.yaml

appdaemon:
  time_zone: Europe/London
  latitude: ##
  longitude: ##
  elevation: ##
  plugins:
    HASS:
      type: hass
      namespace: HomeAssistant
      ha_url: ##
      token: ##
    MQTT:
       type: mqtt
       namespace: mqtt
       client_host: ##
       verbose: True
http:
  url: http://raspberrypi:5050
admin:
api:
hadashboard:

And my apps.yaml
home_presence_app:

  module: home_presence_app
  class: HomePresenceApp
  plugin:
    - HASS
    - MQTT
  known_devices:
    - ## Pixel3
    - ## HuaweiP
  depart_check_time: 30
  depart_scans: 3
  minimum_confidence: 60
  not_home_timeout: 15
  system_check: 30
  system_timeout: 60
  log_level: DEBUG

However, when running I'm constantly getting this errror

I cannot find any reason why the critical error is showing, but nothing seems to be working so guessing this is the first issue to tackle

Hello @Shaun-Harrison,

First apologies for the late response. The issue might be how the message is sent from your node. Please ensure that the nodes don't use weird characters in the topic name or something.

I also know the error logs in the MQTT plugin is not so greate so will need to create better ways of outputting the errors so its clearer. But if your issue has been fixed, cool.

Regards
