Mqtt integration entities have duplicate names

[Largus72]

For several days now, all device entities added by the MQTT integration have had duplicate names.
There is nothing wrong with the names of the devices itself.

I run the Mosquito MQTT Broker Add-on on the Home Assistant and use the MQTT integration.
In the meantime, I have already removed all devices, both once via Home Assistant itself and via MQTT Explorer.

Within my Home Assistant, MQTT adds 35 devices, with a total of 110 entities, so renaming is not an opions.

Below is an example of 2 lamps. First the devices, then the entities.
How can I get this back in order quickly?

Hi Fransis,

I have come across this message, and others. Just not the way I can solve this.

I have no idea if the problem lies there, but I do see an issue (MQTT Name changes in Home Assistant 2024.2.0 #99). I just don’t see many responses there
In the meantime, unfortunately, I am left with 110 entities that I have to rename manually.

Probably Homey did not update it’s app to the new format.
