if we remove a device, we can add it back but it loses the unique device number, causing automations to break. I found this out not too long ago, and in my like 200 automations i probably have around 800 device ID's.
I now have to manually open all automations to delete the device and add entities instead. This will probably take me many, many hours. while currently home assistant knows what entity it has to react with. or you could ask the user for confirmation....but no..there's no way to convert this all.
It makes me feel device ID is something broken, and could have been fixed. If entity matches, take on the last device ID, for example. or ask if thats ok. Or simply delete devices...
Oh well, its a sunny sunday afternoon so lets pour some time into this....
