FAQ
1. The Zigbee signal is unstable and the device frequently goes offline?
If your device often goes offline, it could be due to the long distance between the device and the gateway (we recommend no more than 50 meters through walls), or obstacles/interference blocking the signal. Try adjusting the placement of your device and gateway, or use additional Zigbee router devices to strengthen your Zigbee network coverage.
2. Missing features after pairing with the eWeLink app?
Please ensure both your Zigbee gateway and the eWeLink app are updated to the latest version. If the device was added using an outdated gateway firmware, remove the device, update the Zigbee gateway, and then re-add the device.
3. Device not working properly in low-temperature environments?
In environments approaching extremely low temperatures (e.g., -20℃ / -4℉), the device may encounter:
① Greater deviation in temperature readings (up to ±0.7℃ / ±1.3℉)
② Significant battery capacity drop
③ Ghosting on the screen during refresh
These effects will improve as the ambient temperature rises. However, please note that due to battery characteristics, the battery capacity may not fully recover.
