To connect your Rain Bird ESP-ME3 system to your smart home, follow these steps:

1. Download the latest Rain Bird mobile app from the App Store or Google Play.
2. Insert the LNK Wi-Fi module into the accessory port of your ESP-ME3 controller.
3. The module’s light should blink red and green, indicating it is broadcasting a Wi-Fi hotspot.
4. On your smartphone or tablet, open the Wi-Fi settings and connect to the network with "Rainbird" in the name.
5. Follow the app instructions to complete the setup and connect the controller to your home Wi-Fi network.

Ensure the controller has a strong Wi-Fi signal. If the signal is weak, move the router or controller closer or use a Wi-Fi booster.
