PIR (Motion sensor)

PIR State

This commands allow you to set/get the PIR state - whether it's enabled or disabled at all. By default, the PIR is enabled.

SET

Byte index	Hex value – Meaning
0	2C – The command code.
1	00 – Disable the PIR sensor; 01 – Enable the PIR sensor. Default state.

Example downlink: 0x2C00 – Disable the PIR sensor.

GET

Byte index	Sent request	Received response
0	2D – Command code	2D – Command code
1		00 - The PIR sensor is disabled. 01 - The PIR sensor is enabled.

Example command: 0x2D

Example response: 0x2D00 – The PIR sensor is disabled.

PIR Active Reporting period

SET

Byte index	Hex value – Meaning
0	2E – The command code.
1	XX – PIR-active reporting period data, bits 15:8;
2	XX – PIR-Active reporting period data, bits 7:0. Default value is 10min.

Example command: 0x2E003C – Set the PIR-Active reporting period to 1min.

GET

Byte index	Sent request	Received response
0	2F – Command code	2F – Command code
1		XX - PIR Active reporting period - bits 15:8
2		XX - PIR Active reporting period - bits 7:0

Example command: 0x2F

Example response: 0x2F003C – Blind period of the PIR sensor is 1min.

Note: Acceptable values: 5...65535sec. (1sec. resolution).

PIR Sensitivity

The PIR sensitivity can be set from 12 to 255. The minimum value we advise setting is 12 or 0x0C - the sensor will be super sensitive to movements.

The higher the value, the less sensitive the PIR sensor is to movement.

Minimum = 12 - very sensitive

Maximum = 255 - less sensitive

SET

Byte index	Hex value – Meaning
0	3Е – The command code.
1	XX - PIR sensor sensitivity. Default value is 20.

Example command: 0x3E1E – Set PIR sensor sensitivity to 30.

GET

Byte index	Sent request	Received response
0	3F – Command code	3F – Command code
1		XX - The sensitivity of the PIR sensor

Example command: 0x3F

Example response: 0x3F1E – The sensitivity of the PIR sensor is 0x1E => converted to decimal => 30.

Note: Acceptable values: 12...255.
