Which Rain Bird controllers are compatible with the LNK WiFi Module?
The Rain Bird LNK WiFi Module is strictly compatible with Rain Bird ESP-TM2 controllers and Rain Bird ESP-Me controllers that were manufactured after November 2, 2016.
Older ESP-Me models or different Rain Bird series will not have the correct firmware or physical port to support this module.
Does the Rain Bird app require a monthly subscription?
No, the Rain Bird mobile app is completely free to download and use. There are no monthly subscription fees to access remote control features, weather data, or real-time alerts.
You only pay for the one-time purchase of the LNK WiFi hardware module.
What type of Wi-Fi network do I need?
The LNK WiFi Module requires a standard 2.4 GHz wireless router to connect to the internet. It is not compatible with 5 GHz-only networks.
Ensure that your Wi-Fi signal is strong enough to reach the location where your Rain Bird controller is mounted.
How should I prepare my Rain Bird LNK WiFi Module for spring watering?
To prepare your Rain Bird LNK WiFi Module for spring, open the Rain Bird app to ensure your firmware is up-to-date, verify the controller is connected to your Wi-Fi, and ensure "Automatic Seasonal Adjust" is toggled on.
This ensures the smart software will automatically suppress watering during heavy spring rain showers, saving you money early in the season.
