Some devices change state after zigbee2mqtt startup

[fedebruni84]

What happened

When I start zigbee2mqtt some devices change state. In particular one Innr Smart Plug switch OFF and another one switch ON, regardless what was precedent state.

What did you expect to happen

I expect no state change

How to reproduce it (minimal and precise)

I have zigbee2mqtt (+mosquitto server) running on a Raspberry Pi and when I reboot it or restart after an update, the problem occurs.
Looking at old issues, at the beginning I thought it was a problem of state.json/cache but I deleted the file and the problem persists. Also adding "cache_state_send_on_startup: false" to configuration doesn't resolve this issue.
In the log I can see that during startup, zigbee send a message to the plug topic with payload "ON" (or "OFF" for the other plug) and I really don't know why.
I have also home assistant mqtt integration but this happens also when home assistant is shutted down.

Could you provide the debug logging of this? First enable debug logging, reboot your system (and watch the issue happen), then go into the data/log directory and post the log here.

To enable debug logging set in configuration.yaml:

advanced:
  log_level: debug

For sure...
Look at device innr_samsungTV for example.

You have to figure out who sends these MQTT messages, probably these are retained MQTT messages and you need to clear them. (http://www.steves-internet-guide.com/mqtt-retained-messages-example/). If that's the case you can clear them by using an MQTT client and sending an empty message to e.g. zigbee2mqtt/innr_umidificatore/set with retained set to true.

Since it's not a Zigbee2MQTT problem I will close this.
