Platform esphome does not generate unique IDs

[DarkWarden85]

The problem

Hi,

I have the following error that keeps showing up in my logs when restarting Home Assistant:

Logger: homeassistant.components.climate
Source: helpers/entity_platform.py:540
Integration: Climate (documentation, issues)
First occurred: 12:55:49 (2 occurrences)
Last logged: 12:56:01

Platform esphome does not generate unique IDs. ID ventilation-controlclimatezehnder_comfoair_550_luxe already exists - ignoring climate.zehnder_comfoair_550

It refers to a climate entity I have set up in esphome. The strange thing is that it works absolutely fine. When looking into core.entity_registry, core.device_registry or the esphome config itself I cannot find any duplicate unique IDs. I've been having this problem since setting up the device nearly two years ago, but I simply cannot get to the bottom of this.
Is there anything else I could do in order to troubleshoot this?

What version of Home Assistant Core has the issue?

Home Assistant 2023.2.3

What was the last working version of Home Assistant Core?

No response

What type of installation are you running?

Home Assistant OS

Integration causing the issue

I have now installed the new esphome version 2023.2.0 and can confirm that the issue is still present.

[verjager]

Might be solved by using App.register_component instead of App.register_climate
See: wichers/esphome-comfoair#20 (comment)

Hi @jgverweij. That is actually my comment on the esphome-comfoair repo. I have posted a possible solution, but am waiting for confirmation that my approach is actually the right one.

[verjager]

Ah, didnt't see that it was you but recognised the same problem on two places. Have been researching this in the past as well, but still cannot seem to get a connection to my whr930.
