Control via LAN
LAN control offers direct device management without cloud dependency, provided the smartphone and device are on the same Wi-Fi network. Features like activity notifications, logs, firmware updates, smart scenarios, device sharing, and deletion are not supported when external network connection is absent.
- Manual Mode: Turn the device on/off via the app or the device itself.
- Auto Mode: Automatically control the device by setting temperature and humidity thresholds. You can configure up to 8 auto-control schedules. Auto mode can be toggled on/off with a double-click of the device button or via the app. Manual and auto modes can operate simultaneously; manual overrides will be followed by auto mode resuming based on sensor readings.
Factory Reset
Deleting the device from the eWeLink app performs a factory reset.
Common Problems
Failure to pair Wi-Fi devices with the eWeLink app
- Ensure the device is in pairing mode. It exits automatically after 3 minutes of unsuccessful pairing.
- Enable location services and grant location permission in your phone's settings. This is necessary to scan for Wi-Fi networks.
- Verify your Wi-Fi network is operating on the 2.4 GHz band.
- Ensure you have entered the correct Wi-Fi SSID and password, avoiding special characters. Incorrect credentials are a common cause of pairing failure.
- Position the device closer to the router for a stable signal during pairing.
Wi-Fi devices are offline
Check the Wi-Fi LED indicator status:
- LED flashes once every 2 seconds: Cannot connect to the router.
- Re-check Wi-Fi credentials.
- Ensure Wi-Fi SSID/password do not contain special characters (e.g., Hebrew, Arabic) that the system may not recognize.
- Your router may have a low load capacity or too many connected devices.
- The Wi-Fi signal may be weak due to distance or obstacles.
- LED flashes twice: Failed to connect to the server.
- Verify your internet connection is stable.
- Your router may be overloaded. Check the maximum number of connected devices and reduce if necessary, or consider a more powerful router.
If issues persist, submit a report via the help&feedback section in the eWeLink app.
