### Payload format
BLE advertisements must contain `070848415f424c45`, which means `shortened local name` = `HA_BLE`. This will make sure BLE monitor recognizes the packet. The packet id is optional (see below). The payload has to contain at least one of the above measurements. It is allowed to have multiple measurements (e.g. temperature and humidity) in one BLE advertisment. However, the data must follow the above format.
