Wireless LoRaWAN Sensor Data Format
LoRaWAN Format: Picture as below, FRMPayload is sensor data.

Sensor Data Definition

Multi-temperature (0x14)
Adapt N-way temperature according to length. If N is 1, the basic temperature type 0x04 can be directly used. If N > 1 channel temperature needs to be transmitted, merge similar data items in the following order.

Type: 1 Byte 0x14
Length: 1 Byte
2*N
Value int16_t No.1 temp
Value ... ...
Value int16_t No. N temp

Multi-humidity (0x15)
According to the length, N channels of humidity can be adapted. If N is 1, the basic humidity type 0x05 can be directly used. If N > 1 channel of humidity needs to be transmitted, merge similar data items in the following order.

Type: 1 Byte 0x15
Length: 1 Byte
N
Value uint8_t No. 1 humi
Value ... ...
Value uint8_t No. N humi

Local Configuration:
Note: Factory reset data uploading is every 10 mins, customers can change data uploading frequency as below: Connect sensor with a USB-C cable to computer for local configuration, through local configuration, you can change the packet frequency. Refer SensorTool Manual.

Multi-temperature（0x14）
Adapt N-way temperature according to length, and if N is 1, the basic temperature type 0x04 can be directly used.

If N>1 channel of humidity needs to be transmitted, merge similar data items in the following order.

FRMPayload Example: 007F101404033C033A15024445
00 7F10 Device Information, 7F is battery level = 31， which means battery is 100%, we measure battery level from 0-31, which means 0-100%. Version is 0x10, which means Rejeee temp/humi sensor.
033C and 033A is temperature, is 0x033C = 828 = 82.8℉, 0x033A = 826 =82.6℉. ℉ is only for US market, for other market sensor will send ℃ by default. The first temp is from built-in sensor, and the second one is from external sensor.
44 and 45 is humidity, is 0x44 = 68 = 68 %RH, is 0x45 = 69 = 69 %RH. The first humi is from built-in sensor and the second one is from external sensor.

Local Configuration:
Note: Factory reset data uploading is every 10 mins, customers can change data uploading frequency as below: Connect sensor with a USB-C cable to computer for local configuration, through local configuration, you can change the packet frequency.
