7. Troubleshooting
If you encounter issues with your KUCACCI TTLock WiFi Gateway G2, refer to the following common problems and solutions:
7.1. Connectivity Issues
- Gateway not connecting to Wi-Fi (Red Light): Ensure your Wi-Fi network is 2.4GHz. The gateway does not support 5GHz Wi-Fi. Verify the Wi-Fi password entered in the app is correct. Try restarting your Wi-Fi router.
- Gateway setup times out: If the app indicates a timeout during setup, unplug the gateway, wait a few seconds, and then plug it back in to restart the process. Ensure your smartphone is connected to the same 2.4GHz Wi-Fi network as the gateway during setup.
- Poor connection between gateway and smart lock: Ensure the gateway is placed within 32 feet (10 meters) of the smart lock. Obstructions like thick walls can reduce signal strength.
7.2. Remote Control Not Working
- Unable to unlock remotely: Check if the gateway is online (blue indicator light). Confirm your smartphone has an active internet connection. Ensure the smart lock is properly paired with the gateway in the TTLock app.
7.3. Gateway to Lock Ratio
While a single gateway can theoretically be equipped with numerous locks, it is recommended to maintain a 1:1 ratio between the gateway and the lock for optimal performance, especially considering the 10-meter distance limitation for stable communication.
