To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and activate the PS-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

	1309	Calculation formula：
	1310
	1311	Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
