Discovered entities with a name that starts with the device name

[tankdeer]

Release 2023.8.0 of Home Assistant introduced some changes to how MQTT entities work. Documented here:

https://developers.home-assistant.io/blog/2023-057-21-change-naming-mqtt-entities/

And now shows with this warning/fix in Home Assistant:

Some MQTT entities have an entity name that starts with the device name. This is not expected. To avoid a duplicate name the device name prefix is stripped of the entity name as a work-a-round. Please inform the maintainer of the software application that supplies the affected entities to fix this issue.

Here's an example of the warning logged in the log file:

2023-08-02 15:33:30.970 WARNING (MainThread) [homeassistant.components.mqtt.mixins] MQTT entity name starts with the device name in your config {'availability_topic': 'octoPrint/mqtt', 'payload_available': 'connected', 'payload_not_available': 'disconnected', 'name': 'Ender 3 Print Status', 'unique_id': 'f3ced1a508db4ed5bd4f3d59757faf2c_PRINTING_S', 'state_topic': 'octoPrint/hass/printing', 'json_attributes_topic': 'octoPrint/hass/printing', 'json_attributes_template': Template<template=({{value_json.state|tojson}}) renders=0>, 'value_template': Template<template=({{value_json.state.text}}) renders=0>, 'device': {'identifiers': ['f3ced1a508db4ed5bd4f3d59757faf2c'], 'name': 'Ender 3', 'manufacturer': 'CREALITY', 'model': 'OctoPrint', 'sw_version': 'HomeAssistant Discovery for OctoPrint 3.6.3', 'connections': []}, 'qos': 0, 'enabled_by_default': True, 'availability_mode': 'latest', 'force_update': False, 'encoding': 'utf-8'}, this is not expected.

I'm no longer seeing this warning for Octoprint after upgrading the plugin to 3.7.0.

EDIT: It's the weekend and I had some time to figure my errors out.

Searching with MQTT explorer for "3.4.0" as I see that the three messages have 'HomeAssistant Discovery for OctoPrint 3.4.0' in common. then clearing the old retained messages did the trick.

All good now.

Many thanks.
