I really have no idea which forum to stick this to. My wife and I both have iPhones, iPad, and one ATV 3rd gen. I would like to get started with home kit. The wiring in our house is fugged / ancient and for example we can't install timers on outside light or bathroom fan because our wiring is old and does not have the third wire (and there is no room in conduits to run lines). So I would like to get started with Home Kit. The thing is can it be tied to TWO Apple IDs? Right now we have separate Apple IDs and Apple TV is signed into mine. Which brand(s) to go with? for starters I'd like to accomplish the following: light bulb outside the house turn on and off at specific time, is it possible to still turn on/off with the wall switch? at specific times (night) have the bathroom lights set to soft white / dim when I turn them on with the wall switch migrate from a programmable thermostat to a homekit so it can be fine tuned depending on weather etc and adjusted when outside the house. We have a set schedule M-Th, and Fri-Sun always on set temp as most of Fridays my wife works from home, but I know this can be tuned better. Thank you for your assistance.
