Unable to delete Duplicate Devices

[spinecho31]

I wonder if anyone is experiencing the same issue or if I have some sort of configuration problem.
Lately I shifted my configuration from using IKEA integration to using the Homekit integration.
This lead to having new entities and configuring them with Powercalc.
The issue now, is I have a whole bunch of duplicate and sometimes triplicate devices

Check this example:

Devices

I have 3 bulbs in the Corridor.

inside the unlabelled device there are no entities assigned

The labelled device has the entities on its correct place and works as intended.

Groups

Using the group feature is also a headache.
I've grouped the lights into one group called "Corridor Lighting"

Now each light has its own personal "Group" and when I try to delete it, it gives me the information that "its not loaded"

Question

Is there a way I clean this up, removing all the dead devices without resetting the whole Powercalc integration (I have a couple of automations running on top of it already)?

@spinecho31 These duplicate entries is a bug which was reported a week ago.
See: #2366

I just released v1.13.2 which should prevent these duplicate entries to be created.

I don't think I can clean up these entries automatically because the HA core code trips on it, because there are multiple with the same unique_id.
Please follow the instructions provided in this comment, that should help you solve it.
I'm sorry for the inconvenience.
