Communication Protocol
The device can be controlled directly via LoRaWAN. For this purpose, different commands are defined, which are
used either 'uplink', i.e. from the device to the LoRa network, or 'downlink', i.e. from the LoRa network to the
device. Commands can be cascaded up to the maximum number of 52 bytes. All values of the command
descriptions are bytes, unless otherwise specified.
Downlink-Commands (using FPort 2):
•
0x03: Get hardware ID, device answers with uplink command 0x03
•
0x04: PP VV_MSB VV_LSB: Set configuration parameter PP for new 16 Bit value VV
•
0x1a: Get firmware version, device answers with uplink command 0x03a
•
0x14 PP: Get configuration parameter PP, device answers with uplink command 0x04
Uplink-Commands (using FPort 2):
•
0x03 XX YY_MSB, YY_LSB: Report hardware version XX and device capabilities bitmap YY
•
0x04 PP VV_MSB VV_LSB: Report 16 Bit Value VV of configuration parameter PP
•
0x06 YY VV_MSB VV_LSB: Report 16 Bit Sensor Value
•
YY=0x01: Temperature in 0.1 Degree Celsius
•
YY=0x03: Uptime in hours
•
YY=0x82: Rain level in measurement interval in 0,5 mm water level.
•
0x0a YY_MSB YY YY YY_LSB: Report firmware version as 32 Bit value
•
0x0b XX YY ZZ_MSB, ZZ_LSB: Report alarm state XX (1 or 0) of alarm type YY with optional value Z. Current
alarm types are 0x03 = sensor alarm, 0x0c = battery alarm
•
0x12: XX YY_MSB, YY_LSB: Battery level. XX = voltage in * 50 mV, YY Consumption since reboot in mAh
Configuration Parameters
Parameter 2 – Heartbeat Interval
Description: This parameter defines after how many measurement intervals the sensor will send a report regardless
of rainfall. The factory default is 24 which translates together with the default value of parameter #1 (900 seconds
= 15 minutes) into 24 * 15 minutes = 60 seconds.
Parameter 3 – Heavy Rain Threshold
Description: This parameter defines the heavy rain level as time interval (in seconds) for 0.5 mm rain. The default
value of 120 means that 0.5 in 120 seconds or less will cause heavy rain alarm. This translates into 15 liter/h.
Parameter 4 – Measurement Interval in Seconds
Description: In case of rain the device reports regularly to the LORA network. This parameter defines the time
interval for these reports in seconds. The default is 900 = 15 minutes. The value range is 10 – 60000.
