Orbit B-hyve XD Sprinkler Timer

Through the B-hyve app and an active Wi-Fi connection, the XD can use local weather information and rainfall forecasts to create or delay watering schedules. Orbit's Smart Watering system also considers details such as soil type, slope, sun exposure, and sprinkler-head information.

The XD can be controlled locally over Bluetooth, but remote Wi-Fi control and weather-based Smart Watering require the appropriate Gen 2 B-hyve hub. Bluetooth-only use also removes automatic weather delays and requires the phone to remain within roughly 50 feet.

Yes, Bluetooth pairing can control and program the timer without Wi-Fi. Orbit's setup instructions specify two fresh AA batteries and note that Bluetooth control requires staying within about 50 feet of the device.
