...your information though, not the product. They'll sell you out if they get the right MBA.
Homekit is dodgy, for some strange reason stuff randomly disconnects from the network here and there, and require a hard reset every so often.
No idea why but homekit sometimes fails to see some devices, but the manuf app is able to work with them.
Siri is also pretty dumb, for example "Turn off Lights" isnt smart enough to turn off any lights that are on. One must say "Turn of ALL lights".
