This can occur if the timer has a program that is running but has lost its connection to the server and is not sending the watering events to the watering history endpoint.
Please ensure your timer is still connected to WiFi. If your WiFi SSID (name) or password has changed you’ll need to connect to the timer to reset the settings. Whether it is or is not connected, a power cycle (unplug and plug back in) might reestablish the connection and get it sending the watering events again.
If power cycling does not not work please contact our tech support team at [email protected] or call 1-800-488-6156 for assistance.
