The most likely reason that you are unable to turn on smart watering is that your timer is not connected to your home WiFi. In order for our B-hyve hose timer models to connect to WiFi, there must be a B-hyve hub for them to connect to. (For the B-hvye XD models you will need our GEN 2 Hub, and for the B-hyve hose timer model you will need our GEN 1 Hub)
Without the hub, the hose timer will only be able to be controlled in the B-hyve App via Bluetooth.
Since the device would only be able to be controlled via Bluetooth, smart watering would not be able to activate/work as it requires both a WiFi connection and a home address to get access to live weather forecast and other information that smart watering uses to create programs, and add delays to programs.

If you have a B-hyve hose timer and the hub that is associated with that device and are still seeing this issue please reach out to our Customer Care Team.
