The payload is present in the "data" field as a base64 value "data":"AAAzMgGA" The base64 value is converted to HEX and the output is decoded using the "decode_MLRT_HB_P_Uplink" function The "decode_MLRT_HB_P_Uplink" function uses HEX Payload as input "data":"AAAzMgGA" in HEX # HEX BUFFER : [0x00, 0x00, 0x33, 0x32, 0x01, 0x80] # In DECIMAL : [0, 0, 51, 50, 1, 128] Example Decoded Output: Sensor_1_Raw: 0 Sensor_1_Offset: 0 Sensor_2_Raw: 25.5 Sensor_2_Offset: 25 Energy_Storage: 0 Radio_Communication_Error: 0 Received_Signal_Strength: 0 Sensor_2_Failure: 0 Sensor_1_Failure: 1 Storage_Voltage: 2.56 | |
