Daikin OnectaWorks CloudOwner reports it works excellently via cloud API
Saved copy
The Daikin AC and Altherma I have all work excellent. The Onecta app and their public API work, but the data they provide is limited, see #46. Also because it is polling there is always a delay and you can only make a limited amount of calls per day. I do hope that at some point we do get a local API again, that would make local control much easier, but until that happens (very unlikely) the public cloud API does work, but it has its limitations.

In ReReHome

Once Home Assistant’s HomeKit Bridge shares it, this device reaches Apple Home as a HomeKit accessory behind your Home Assistant bridge, so ReReHome shows and controls it like any other.
