Hi Raynaud,

When the timer is attached to the faucet, you can do the following steps to test if the timer can connect to the WiFi router:

1. Take the timer outside to the faucet. Press the power button for 3 seconds to turn on the timer. If the timer is already on, turn it off first by pressing the power button for 3 seconds
2. The timer will try to connect to the router
3. Wait for 15-30 seconds
4. If the connection is successful, the LED light will turn green
5. If the connection is unsuccessful, the LED light will turn red. You might need to move the timer closer to the router or add a WiFi extender

Thanks,
