Device allowed working voltage

This command sets the allowed working voltage. If the battery voltage drops below the set value the valve state is automatically set to open and can’t be changed anymore.

Setting a value less than 0x1F is not acceptable as it is not sufficient for the operation of the onboard MCU and/or radio!

SET

The command explanation is in the table below.

Byte index	Hex value - Meaning
0	09 – The command code
1	XX - Allowed working voltage XX = (Voltage[mV] - 1600) / 8 Default value is 1850mV

Example command: 0x0932

32[HEX] = 50[DEC]

50 = (Voltage[mV] - 1600) / 8 Voltage[mV] = 50 x 8 + 1600 = 400 + 1600 = 2000mV = 2V

Set the working voltage to 2 Volts

GET

The command explanation is in the table below.

Byte index	Hex value - Meaning
0	11 – The command code
1	XX - Allowed working voltage XX = (Voltage[mV] - 1600) / 8

Example response: 0x111F

1F[HEX] = 31[DEC]

31 = (Voltage[mV] - 1600) / 8 Voltage[mV] = 31 x 8 + 1600 = 248 + 1600 = 1848mV = 1.848V

The device will stop working when the voltage drops below 1.848V
