Zepp Tennis Sensor Requirements

The Zepp Tennis app only supports the Zepp Tennis 2 sensor. The Zepp Tennis 2 sensor has different capabilities, and different internal components, then the Zepp 2 Golf/Baseball sensor or the Zepp 1 multi-sport sensor.
As such, you cannot use the Zepp 2 Golf/Baseball sensor or the Zepp 1 multi-sport sensor with the Zepp Tennis app. You also cannot use the Zepp Tennis 2 sensor with the Zepp Golf or Zepp Baseball apps.
