I got the nest installed a few weeks ago and have been playing around with the home/away assist. To begin with I had both my phone and the thermostat set to decide if someone is home but it wasn’t triggering so best suggested switching to just my phone for a few weeks to let it settle which worked great but if I was out and someone was home no heating
So I thought I’d switch it back to both yesterday and again it isn’t triggering that I am out. Does it take a while to trigger that no one is home if it’s set to both? For example If I go out to do the school run and am gone 30 mins is that not long enough?
