Payload description

This chapter describes the structure of the telemetry data. The number of bytes in the payload depends on the configuration of the sensor. The payload is made up depending on which sensors are provided in your product. In principle, each version has a header. This has information about the version and status of the sensor and also contains a master measured value. This measured value can simply be assumed to be the current measured value. The header is followed by an additional payload section that contains further information, such as special parameters for the measuring principle or settings for position and opening detection.

📢 Not every sensor has an additional payload section.
