I know when the house is on generator power that there's a specific way to shut it down (video below). I did that today when we went to visit my dad so it wouldn't run while we weren't there, but we apparently have power back. I was thinking my SmartThings hub would come back online to let me know, but it hasn't. My Ecobees aren't up either and I know our internet is working as it's fiber and has had zero issues, but not totally ruling it out.

I'm guess when I turned the transfer switch off, it never transferred back to shore power (whatever it's called), so that's why.

When I get home, do I need to just turn the transfer switch on and it'll click over once it realizes power is back on? And then when I turn the generator to "auto," I'm assuming it'll see it has power and just go back into standby mode rather than starting. Is that correct? I see a video of what to do to shut it down but nothing on what to do if power comes on while you have it down.

Followed this video to shut it down:
