This article describes some common remote commands that you can issue through the LoRaWAN server to achieve remote control of the device.
The port number is 3.

- ADR:
01 represents ADR, and 00 represents fixed DR.
- Confirm:
01 represents confirm, and 00 represents no confirm.
- Interval: LoRaWAN reporting interval, HRI-3633 will send the valve status to the server according to the Interval. In hexadecimal, in seconds. In this sample,
64 means 100 seconds.
- DR: When fixed DR is enable. In this sample,
01 means DR 1.
- Power: RF power, unit'dbm'. In hexadecimal, in seconds. In this sample ,
16 means 22dbm.
- Timezone:
00 represents East, 01 represents West. Example 00 08 means East 8.

Query GPIO status
| Description | Command type | Quantity | Mode Change | Mode | Status |
|---|
| Length | 1byte | 1byte | 2byte | 2byte | 2byte |
| Query | 02 | | | | |
| Feedback | 02 | 02 | 00 03 | 00 03 | 00 03 |
| Error | 02 | FF | | | |
- Quantity: Quantity of GPIO.
- Mode Change: Each bit representing the state of a GPIO.
0 means "Mode change enable", 1 means "mode change disable". In this sample, hexadecimal value 03 converted to binary value "11", means 2 GPIO are "change enable".
- Mode 2byte: Each bit representing the state of a GPIO.
0 means "input", 1 means "output". In this sample, hexadecimal value 03 converted to binary value "11", means 2 GPIO are "output".
- Status: Use 4 bits represent the state of a GPIO, and each representing the state of a GPIO.
0 means "low", 1 means "high". In this sample, hexadecimal value 03 converted to binary value "11", means 2 GPIO are "high".
Set a single GPIO state

| Set | 03 | 00 | 01 | 00 | 00 |
| Feedback | 03 | 00 | 01 | 00 | 00 |
| Error | 03 | 00 | FF | | |
- Quantity:
00 means set a single GPIO.
- Mode:
0 means 'input', 1 means 'output'.
- State:
00 means 'low', 01 means 'high'.

| Feedback | 03 | 01 | 01 | 00 | 00 |
| Error | 03 | 01 | FF | | |
- Quantity:
01 means set multiple GPIO.
- Number: Each bit representing a GPIO. In this sample, hexadecimal value
03 converted to binary value "11", means 2 GPIO will be set.
- Mode: Each bit representing a GPIO. In this sample, hexadecimal value
03 converted to binary value "11", means GPIO0 is 'high' and GPIO1 is 'high'.
Query RS485 commands

| Feedback | 06 | 01 | 01 | 00 | 13 | 10 | 7F |
| Error | 06 | FF | | | | | |
- Number: Command number on the configuration page, 0~15.
- State: Command state,
01 means enable, 00 means disable.
- Operation type:
00 means periodic command, 01 means timed task.
- Time(hour): Which hour in a timed task, in this sample,
13 means 1 p.m. When "Operation type" is 00 (periodic), this section is invalid.
- Time(minute): Which minute in one hour in a timed task, in this sample,
10 means 13:10. When "Operation type" is 00 (periodic), this section is invalid.
- Repeat: The way of repeat about timed task. We use 8 bits from low to high, representing Sunday to Saturday. For each bit,
0 means don't operation, 1 means operation, then converted to hexadecimal. In this sample, 7F == '0111 1111', means this command operation everyday.
