A presence sensor says whether someone is in a room. With the home agent, Readout uses one to keep an eye on the household, gently.

​
Adding a sensor

Sensors are added the way lights are, under Add lights in Menu → Lights:
  • Matter presence sensors, Meross’s MS600 and MS605 among them, with their pairing code.
  • Home Assistant’s occupancy, presence and motion sensors, an Aqara FP2’s zones among them.
They’re listed under Sensors, each saying whether someone’s there, or since when nobody has been.

​
What a sensor can do

Choose from 2 to 12 hours. Only the hours between 7 am and 10 pm count, so a night’s sleep doesn’t. The family is told once, through Menu → Notifications → A room has seen nobody for hours, until someone’s there again.
The first time each day the sensor sees someone, within the morning hours you choose (5 to 9 am). It suits a room people pass through once they’re up, like the kitchen.
From 10 pm to 7 am, one of your lights or plugs comes on as someone comes in, at 10% where it dims, and goes off once the sensor has seen nobody for 2 minutes.
With an OBSBOT Tiny 2 as the webcam on Readout’s screen, a sensor can wake it to follow whoever comes in. Otherwise it sleeps, pointing down, whenever there’s no drop-in or call. Camera stays asleep keeps it that way.
