I'm turning the "away from home" function on, but it's not responding to motion. I have double checked that notifications are on, and that the settings call for alarm lights with motion detected. I am using one motion sensor and have space sense set up in two other rooms. When I press play all the lights go out and it seems to be armed, but after a few minutes when I start to move around the house nothing happens. I can walk through all three motion detection areas with no response. All the motion inputs work normally in their own.
