How Nest products help presence sensing

Some Google Nest products can use their sensors to detect activity in your home.

These are the sensors each product uses to detect activity:

  • Nest Learning Thermostat and Nest Thermostat E: A motion sensor detects movement in the room. Your thermostat also notes if you manually adjust the temperature on the device.
    • Note: Google Nest Temperature Sensors don’t have activity sensors, so they can’t help with presence sensing.
  • Nest Thermostat: A Soli sensor detects motion proximity and presence of nearby objects. The Nest Thermostat also notes if you manually adjust the temperature on the device.
  • Nest Protect: An occupancy sensor detects if someone is in the room.
    • Note: To maximize battery life, battery powered Protects check in less often, but they can work with other Nest products to help improve presence sensing accuracy.
  • Nest Guard: A motion sensor detects movement in the room. Nest Guard also notes if someone has armed or disarmed it with Nest Tag, the Nest app, or a password.
  • Nest × Yale Lock: An optical sensor detects if the bolt is open or closed.
  • Google Nest speaker or display: Notes if someone interacts with the device using touch or voice control.
  • Google Nest Hub (2nd gen): In addition to touch or voice control, a Soli sensor detects if someone is nearby.

Note: Nest cameras, Nest doorbells, and Nest Hub Max's camera won’t switch devices in your home between Home and Away modes.
