Frequently Asked Questions
Do I need a hub for these sensors?
Yes, most of these devices use Zigbee technology, which requires a compatible smart home hub (like an Aqara Hub or compatible Xiaomi gateway) to communicate with your mobile app.
Can these work with my existing camera system?
Absolutely. By using platforms like Apple HomeKit or Mi Home, you can set "if-this-then-that" rules, such as having your security camera start recording the moment a door sensor is triggered.
Is the installation difficult for beginners?
Not at all. These sensors are designed for DIYers and usually come with pre-applied adhesive tape. You simply peel, stick, and pair through the app.
How long do the batteries last?
Due to the efficiency of the Zigbee protocol, these sensors often last between 1 to 2 years on a single coin-cell battery under normal usage conditions.
What is the difference between the E1 and the original sensor?
The E1 model supports the newer Zigbee 3.0 standard, which offers better connectivity and power efficiency, though the original version remains a gold standard for basic reliability.
