FAQ of window alarm sensors
1. Q: Does this magnetic door/window sensor work with a standard WiFi router (without a hub)?
A: Yes. This sensor is a WiFi-based magnetic door/window sensor (not Zigbee), so it connects directly to your home WiFi network — no extra gateway or hub required. It supports 802.11 b/g/n, making it easy to pair with most standard 2.4 GHz WiFi routers.
2. Q: How long does the battery last and how do I know when to replace it?
A: Under normal indoor use, the battery life typically lasts several months. According to the manual, the sensor draws very low standby current (so it’s energy-efficient). When battery voltage falls below a certain threshold, the system (or app) usually triggers a low-battery alert, prompting you to replace the battery.
3. Q: Is installation complicated? Do I need tools or special wiring?
A: No, installation is generally simple. The sensor is battery-powered (no wiring), and typically attaches with adhesive tape or screws. Then you pair it with your WiFi via the companion app (such as Smart Life / Tuya), by entering your WiFi password. Once paired, the sensor is ready — no professional installation required.
4. Q: Can this sensor send real-time notifications to my smartphone?
A: Yes. Once paired with the Smart Life/Tuya app, the sensor can send instant push notifications whenever the door or window is opened or closed. You can also check the event history directly in the app.
5. Q: How far can the sensor be from my WiFi router?
A: The working distance varies depending on your home layout. In most cases, it performs reliably within 10–30 meters indoors, assuming normal walls. Thick concrete walls, metal surfaces, or large appliances may reduce the WiFi signal range.
6. Q: Will this sensor work on sliding or double-leaf doors and windows?
A: Yes, as long as the magnet and sensor can be aligned closely when the door/window is closed. Ensure the two parts are installed parallel and within the recommended distance (usually a few millimeters) for reliable detection.
