I can’t help you with that, since I’m not currentlyl using HA. I’ve got an old LiteTouch lighting automation system in my house, and am running UDI’s Eisy home automation box, which has great Insteon support. I’m using the KLF via its contact closure, as that is the easiest way to get my over a quarter of a centry old LiteTouch system to operate the skylights, but that doesn’t report open/close status. So, to get status back I’ll need to (finally) get on the Home Assistant bandwagon, but I’m a bit hesitant to start up a third home automation controller/system.
I’m using the KIG as Velux intends - via its own mobile app and its own scheduled automations. I can do some schedules/automations via LiteTouch for the skylights, but it’s pretty limited).
I think this post/thread is relevant for you:
