So Yurii’s suggestion to use IFTTT works like a charm and will be perfect for my needs!
For me It’s about turning on the cameras, and the motion detection, when I’m NOT home. Currently I have to manually turn them off whenever I’m home to avoid motion detection notifications constantly. Then I have to remember to turn them on when I leave; which I usually forget. This is especially a hassle if you are going in and out.
I have routines set up with google assistant when I leave and come home. The very least I would expect in the integration is the ability to turn them on and off together with my home/away routines.
You may try adding “turn off (camera name)” as a “try adding your own” trigger on the routine. I’ve started having the opposite problem. I want to keep my cameras on but recently Google started turning them off along with everything else when I turn off a room. I don’t remember it ever doing that before. Maybe they added a power off ability I didn’t even consider they might not have had before in the first place? In any case your scenario may just work now.
