because KCS v2 for KC868-A64 and KC868-A128 sometimes not very stable, not enough memory.
we suggest use this special firmware KCS v1.0.27 for KC868-A64 and KC868-A128. 
improvement:
support timer set delay value from (1-65535), before version is (1-255).

I am using KC868-A16S and two regular switches, with firmware version KCS V2.1.9

I have attempted to create an automation, but it was unsuccessful, and I am unsure of the cause. Here is the description of the automation

The condition for Output 1 to work is that the second input is always in the OFF position and the first input is in the ON position.

 Output 1 is turned off if either the first input is switched to the OFF position or the second input is switched to the ON position.

Hi everyone, I am new to Kincony products, and have liked them very much until now. 

I have 12x KC868-A4 boards and 24x Dwyer DM-200 Differential Pressure Transmitters connected to the A4 boards on the A1 and A2 inputs that are 4-20mA. (Please refer to enclosed file: Dwyer DM-200).

The DM-200 Transmitter has a range (measured and confirmed) of 4mA = 0 Pascal (Pa) and 20mA = 62.21 Pa (Please refer to enclosed file: Instrument Scale), therefore, I assumed that Custom Value 1 is 0 Pa and Custom Value 2 is 62.21 Pa (Please refer to enclosed file: 4-20mA Scale).

When we go to "Monitor" icon to see what values Kincony is reading live at around 37 Pa on Dwyer, Kincony is showing 35 Pa, and at 0 Pa on Dwyer, Kincony is showing around 8 Pa. The 4-20mA signal is clearly arriving to Kincony, we checked the values of the signal and we get 4mA and around 12 to 14 mA when values of 30 and up Pascal. 

Thinking we where doing something wrong, we put: Custom Value 1 to "-15.56" Pa and Custom Value 2 to 62.21 Pa, like Instrument Scale picture, and values were also not coincident. 

We think there is a problem with scaling inside the KCS_KC868_A4_V2.1.9 firmware. 

Can you check? And let me know?

Thank you.

Hello, I would like to understand the logic, on the board, I find 3 I2C ports:

I2C-0
I2C-1
I2C-10

When i make this: 

i need A4 module to drive 5v IR module with length of cable of up to 2 meter.
our can i get the 5v
