Light Two Troubleshooting


  • Turn off cellular data. Wi-Fi Assist features on both iOS and Android devices can interfere with your local Wi-Fi networks by switching to the strongest network available inadvertently.
  • Check your network. Ensure you're connected to a network broadcasting at 2.4 GHz. -- If in doubt, create a guest network using default router settings.

    Wi-Fi requirements are:
    • 802.11b/g/n (2.4 GHz) -- dual band (2.4 / 5 GHz) supported, but "blended" networks are NOT recommended.
    • WPA2 Personal (WPS and WPA2 Enterprise are NOT supported)
iOS (Apple)
  • Connect to the desired Wi-Fi network you wish to add the controller to via your phone's Wi-Fi settings.
  • Apple saves your Wi-Fi network password(s) and will share it with the Rachio app.
  • Connect to the desired Wi-Fi network you wish to add the controller to, via your phone's Wi-Fi settings, to ensure you have the correct password.
  • Unlike Apple, Android devices DO NOT save your Wi-Fi network password(s) to share automatically with the Rachio app.
