It would be nice if it was possible to have ‘merged’ devices and their entities.
What I mean is probably best explained with an example.
My Aircos (Mitshubishi Electric) can be controlled from HA through the Melcloud integration. I can also get these Aircos in HA through my ‘Niko Home Control’ Integration which also talks to Melcloud.
However, both these have a relatively long update interval.
It would be much easier if I could ‘Merge’ the devices into one. Overlapping entities could be merged also to give a more accurate status (depending on which integration supplied a value last).
Actions could be sent to whichever of the integrations provided the latest status.
Another example is Tesla Fleet API + Tesla BLT (Esphome).
