A No ET Communication Alert is a communication alert that occurs when ET data (Evapotranspiration) has not been received for 5 days. The controller will continue to irrigate all stations using the last received ET message for 5 days. After 5 days the controller will use the backup ET value.   

Possible Causes:

• Improper microzone has been assigned to the controller
• Intermittent communication
• The ET subscription has expired
• Make sure controllers' antenna is not inside a metal enclosure. Cell signals can penetrate plastic, but not metal. If placing a controller inside a metal enclosure, be sure to install an external antenna.

Possible Fixes:

• Call HydroPoint Customer Service to verify the microzone and ask for a new ET signal to be sent. Confirm ET message is received.
• Renew WeatherTRAK ET Everywhere subscription.

To clear a No ET Communication Alert:

A No ET Communication Alert will automatically clear when communication is restored.
