HomeAssistant MQTT Breaking changes in 2023.8+

[yozik04]

Hello @nielsonm236,

I trust you are well!

HomeAssistant has thrown some work at us. See Breaking changes, "MQTT" section "Naming of MQTT entities" New entity naming guidelines

Currently we are getting next log lines in the HomeAssistant 2023.8:

2023-08-22 20:31:27.404 WARNING (MainThread) [homeassistant.components.mqtt.mixins] MQTT entity name starts with the device name in your config {'unique_id': '3a7c01fb9b5a_output_07', 'name': 'heat1floor output 07', 'availability_topic': 'NetworkModule/heat1floor/availability', 'state_topic': 'NetworkModule/heat1floor/output/07', 'command_topic': 'NetworkModule/heat1floor/output/07/set', 'device': {'identifiers': ['NetworkModule_3a7c01fb9b5a'], 'model': 'HW-584', 'manufacturer': 'NetworkModule', 'name': 'heat1floor', 'sw_version': '20220921 0050', 'connections': []}, 'enabled_by_default': True, 'optimistic': False, 'qos': 0, 'payload_not_available': 'offline', 'retain': False, 'payload_available': 'online', 'encoding': 'utf-8', 'payload_off': 'OFF', 'payload_on': 'ON', 'availability_mode': 'latest'}, this is not expected. Please correct your configuration. The device name prefix will be stripped off the entity name and becomes 'output 07'

To fix this we need to strip device name from the beginning of 'name' attribute.

'name': 'heat1floor output 07' should become 'name': 'output 07'

That will fix the issue.

OK - Should be easy to do. How soon is this needed?

Till February 2024 😄

Just to clarify the above ONLY affects the Auto Discovery messages, but not any of the other Subscribe or Publish messages, correct? Update: Don't need an answer. I made the changes to the Auto Discovery payload, updated Home Assistant to the latest revisions, and tested the code changes. Both the old and new firmware seems to work fine. I will release with the next General Release.

Addressed in release 20231009 1022

I can confirm that warnings are now gone.

Thank you. Nice when a fix actually works. :-)
