Description

In zigbee2mqtt rename device with the box "Update Home Assistant entity ID" checked, changing the entity ID from, e.g., "climate.trv_küche" to "climate.trv_kueche".

Steps to Reproduce

Expected behavior:

I expect renaming to be handled more gracefully.

Actual behavior:

The log shows this exception multiple times:

You are renaming the device inside home assistant.
Why should better Thermostat pick up the new name, if to this plugin it just looks like there is a new thermostat installed.
This behaviour is totally expected and not a bug.

I mean. Correct me if I'm wrong, but better Thermostat has no knowledge about changes within home assistant, so this is unfixable.
Just don't rename your thermostats or simply set up a new one within better Thermostat.
