MQTT device name is equal to entity name in your config

[dylan09]

Describe the bug I have one Shelly 1PM in my configuration. For this device I get a few Warning messages in HA logs:

Oct 31 16:57:14 haos.home.umartiensen.de homeassistant[559]: 2023-10-31 17:57:14.618 WARNING (MainThread) [homeassistant.components.mqtt.mixins] MQTT device name is equal to entity name in your config {'name': 'hz_sw_heizung', 'command_topic': 'shellies2/hz_sw_heizung/rpc', 'payload_off': '{"id":1,"src":"home-assistant","method":"Switch.Set","params":{"id":0,"on":false}}', 'payload_on': '{"id":1,"src":"home-assistant","method":"Switch.Set","params":{"id":0,"on":true}}', 'state_topic': 'shellies2/hz_sw_heizung/status/switch:0', 'value_template': Template<template=({%if value_json.output%}on{%else%}off{%endif%}) renders=0>, 'state_off': 'off', 'state_on': 'on', 'availability': [{'topic': 'shellies2/hz_sw_heizung/online', 'payload_available': 'true', 'payload_not_available': 'false'}, {'topic': 'shellies2/hz_sw_heizung/status/rpc', 'value_template': Template<template=({%if value_json.mqtt.connected%}online{%else%}offline{%endif%}) renders=0>, 'payload_available': 'online', 'payload_not_available': 'offline'}], 'unique_id': 'shellyplus1pm-a8032abe28ec-0', 'qos': 0, 'device': {'connections': [['mac', 'A8:03:2A:BE:28:EC']], 'name': 'hz_sw_heizung', 'model': 'Shelly Plus 1PM', 'sw_version': '20231031-152218/1.0.7-g5db02bd', 'hw_version': 'gen2 (SNSW-001P16EU)', 'manufacturer': 'Allterco Robotics', 'configuration_url': 'http://shellyplus1pm-a8032abe28ec.local/', 'identifiers': []}, 'origin': {'name': 'Shellies Discovery Gen2', 'sw_version': '2.20.0', 'support_url': 'https://github.com/bieniu/ha-shellies-discovery-gen2'}, 'retain': False, 'payload_not_available': 'offline', 'payload_available': 'online', 'encoding': 'utf-8', 'enabled_by_default': True, 'availability_mode': 'latest', 'optimistic': False}, this is not expected.

I am out of ideas. Have deleted the device from Home Assistant. Deleted all related entries from MQTT broker. Every time I start the script the warnings are back in log file. They are not there for all sensors. I get them for Energy, Frequency, Power, Temperature and a few other.

For Input 0, Firmware, Cloud, ... and others there are no error messages.

What else could I do, to get the entity names correct?

Expected behavior I hoped to get rid of the warnings.

Versions:

• Home Assistant: 2023.10.5
• Shellies Discovery GEN2: 2.20.0
• Shelly device firmware: 1.0.7

Shellies Discovery GEN2 automation:

- id: shellies_discovery_gen2
  alias: "Shellies Discovery Gen2"
  mode: queued
  max: 999
  trigger:
  - platform: mqtt
    topic: shellies_discovery/rpc
  action:
  - service: python_script.shellies_discovery_gen2
    data:
      id: "{{ trigger.payload_json.src }}"
      device_config: "{{ trigger.payload_json.result }}"
  - service: mqtt.publish
    data:
      topic: "{{ trigger.payload_json.result.mqtt.topic_prefix }}/command"
      payload: "status_update"

Is the device name in the device configuration the same as the output name (hz_sw_heizung)?

[dylan09]

Yes. Same Name. And the MQTT prefix is shellies2/hz_sw_heizung

Will it work if I rename the device in Shelly Configuration?

[bieniu]

You should change the device name or the output name.
