A small two-piece sensor that tells you the moment a door or window opens. One half sticks to the frame, the other to the door, and when they separate the sensor sends a message to your hub — which pushes a notification to your phone wherever you are. It uses a solid-state hall sensor rather than the old glass reed switch, so there is nothing mechanical inside to wear out or break. Once it is on your network it can trigger other things too: a lamp that comes on when the back door opens, or a routine that tells you the garage was left open.

4	Once it appears in the app, decide where it goes.
5	Stick the larger half to the frame and the smaller magnet to the door.

8	Set up any notifications or routines you want in the app.

IMPORTANT NOTES

• A Zigbee 3.0 hub is required. This sensor does nothing on its own and it will not join a WiFi network. Check the compatibility section above before you buy.
• This is a notification sensor, not an alarm system. It has no siren. It tells your hub a door has opened, and your hub tells your phone. It is not a monitored alarm and it will not satisfy any home insurance requirement for an alarm.
• It detects the two halves separating. It does not detect motion, people or animals.
• Notifications depend on your hub being powered and your internet being up. If either is down, you will not be told.
• Keep the gap between the two halves small. If the halves are too far apart when the door is closed, the sensor will think the door is open.
• Indoor use. -10°C to 50°C. In an unheated garage or shed through a UK winter, expect the battery to last less time than indoors.
• Please allow slight variation in measurement as items are measured by hand.
