AirCon and MQTT issues

Hi All,
I configured the AirCon addon to run my AirConditioner through the AEH-W4E1 HW. The addon detect corretcly the wifi HW of the AC but it seems having issue with MQTT.

Here the AirCon addon logs:

D0408 16:25:41.998  selector_events.py:58] Using selector: EpollSelector

Here the CORE logs:

Platform mqtt does not generate unique IDs. ID ca2c4fad63c2 already exists - ignoring climate.piano_terra
 16:29:10 – (ERRORE) Termostato - il messaggio si è verificato per la prima volta alle 4 aprile 2022, 23:04:06 e compare 9587 volte

Here the MQTT logs:

1649428150: New connection from 172.30.32.1 on port hidden3.
1649428150: New client connected from 172.30.32.1 as auto-4BE41805-BCD8-8468-8BFF-5C3F78D43EE0 (p2, c1, k60, u'hidden4').
1649428150: Socket error on client auto-4BE41805-BCD8-8468-8BFF-5C3F78D43EE0, disconnecting.
```Any ideas on how to solve it?

Thanks in advance
Alessandro

Home Assistant believes that device_id is already in HA, which usually means you have not cleared a old integration of that equipment before connecting a new install of the same equipment.

Thank You Sir_Goodenough - do you have any suggestion on how to clear the integration?

Open your Home Assistant instance and show your devices.
Remove the device from here, restart HA to reload everything, and try again.

I did but I am getting the same error. I tried also to uninstall the addon that create the device but I fall on the same the behavior :frowning:

Anyone have any additional idea? or logs to see to understand the root cause of the issue?
