Does it need a separate hub or bridge?
Does it need a separate hub or bridge?
No. The PR57 connects directly to your 2.4GHz WiFi network — no hub, no bridge, no extra hardware required. Just download the Smart Life app, connect, and it's live.
How do I get notified when a door opens?
How do I get notified when a door opens?
The Smart Life app sends an instant push notification to your phone the moment the sensor detects separation — whether it's a front door, back door, window, or drawer.
Can my whole family receive alerts?
Can my whole family receive alerts?
Yes. You can share the sensor with multiple family members through the Smart Life app so everyone gets notified at the same time — useful for parents tracking kids coming home, or couples monitoring the same property.
Does it work with Alexa or Google Home?
Does it work with Alexa or Google Home?
Yes. The PR57 is compatible with Amazon Alexa and Google Assistant — you can ask your voice assistant the current status of any sensor or include it in smart home routines and automations.
Can it trigger smart lights automatically?
Can it trigger smart lights automatically?
Yes. Using Smart Life scenes, you can set your smart lights to turn on automatically whenever a door opens — useful for hallways, garages, or late-night kitchen runs.
How is it installed?
How is it installed?
Adhesive tape is included — just peel and stick the sensor on the door frame and the magnet on the door itself. No drilling, no tools, and no damage to surfaces.
What batteries does it use?
What batteries does it use?
Two AAA 1.5V batteries per sensor, not included. Battery life is long given the ultra-low quiescent current of ≤8µA.
What's the maximum gap before it stops detecting?
What's the maximum gap before it stops detecting?
The magnetic control distance is ≤10mm — if the door or window opens more than 10mm from the magnet, the sensor registers it as open and sends an alert.
