Help > Sensor Types > [0x1F] Binary input

•         The return value is non-zero unsigned 2-byte wide containing a state, a class and a counter of the binary input. The format is the following:

•         b.0                   0: binary input is inactive
                  1: binary input is active

•         b.1-b.7            Counter of the input state changes. Maximum value 0x7F overflows to 0x00.

•         b.8-b.14           Class of the binary input

•         0x00           Unused

•         0x01-0x0F   Unspecified1-Unspecified15

•         0x10           Window open

•         0x11           Door open

•         0x12           Flood

•         0x13           Presence

•         0x14           Fire

•         0x15           Smoke

•         0x16           Water level error

•         0x17           Power on

•         0x18           Occupancy

•         0x19           Problem

•         0x1A          Moisture

•         0x1B          Light on

•         0x1C          Heat on

•         0x1D          Garage open

•         0x1E          Charging

•         0x1F           Motion

•         0x20           Tamper

•         0x21           Locked

•         0x22-0x7F   Reserved

•         b.15                 0: value ok
                  1: error

 

The recommended visual numeric representation is the c.s.nnn where c is class in decimal radix, s is a state and nnn is counter. Example: 16.0.123 is Closed window while the window was open/closed 123 times.

 

•         FRC 2-byte: FRC return value equals unmodified return value.
