3. Setup Guide
Follow these steps to set up your SINGCALL WE57 SOS Emergency Button with the Tuya Smart app:
- Download the App: Download and install the 'Tuya Smart' or 'Smart Life' app from your smartphone's app store.
- Add Device: Open the app and tap 'Add Device'. Navigate to the 'Sensors' category and select 'Emergency Button (Wi-Fi)'.
- Connect to 2.4GHz Wi-Fi: Ensure your smartphone is connected to a 2.4GHz Wi-Fi network. The device requires a 2.4GHz network for initial setup. If your router broadcasts both 2.4GHz and 5GHz, select the 2.4GHz option.

- Pairing: The app will begin searching for the device. Ensure the SOS button is powered on and within range of your Wi-Fi router.

5. Maintenance
The SINGCALL WE57 SOS button uses a LIR2450 rechargeable battery. While specific charging instructions are not provided, ensure the device is regularly charged to maintain functionality. Due to its IP55 waterproof rating, it is protected against dust and low-pressure water jets, but it should not be submerged in water.
6. Troubleshooting
- Device not connecting to Wi-Fi:
The pager must always be in the 2.4GHz Wi-Fi environment in which it was registered in the app. Ensure your router is broadcasting a 2.4GHz signal and your phone is connected to it during the initial setup. - Phone not receiving prompt information/notifications:
When registering the SOS Wi-Fi button with the Tuya app, ensure all notification permissions are enabled for the app. After setup, your phone can receive notifications even if it's on a different network, but the pager itself must remain connected to the registered Wi-Fi network. Check both the Tuya app's notification settings and your phone's system notification settings.

- Consistent Wi-Fi Connection: For continuous functionality, ensure the SOS button remains connected to the 2.4GHz Wi-Fi network it was initially paired with.
- Notification Settings: Always double-check that notification permissions are fully enabled for the Tuya Smart app on all linked smartphones to ensure timely alerts.
