Sensors

Know what's happening at home, wherever you are. Door, window, motion and leak sensors nudge your phone when something changes, from a door left open to water under the sink.

Before you buy

  • Most need a Zigbee hub. Most battery sensors use Zigbee and need a hub, but last for years on a coin cell.
  • Presence or motion? Presence sensors notice people sitting still; motion sensors only detect movement.
  • Catch leaks early. Put one under the washing machine, dishwasher or boiler to catch drips before they matter.
