Hi

To allow easy integration to some of the tools I'm using, I'd like to have the option to monitor/control KC boards (such as the KC868-AI) via a REST API. Would it be possible to add this to the KCS firmware?

I could probably roll my own, but would like something officially integrated into KCS.

Hi

(Running KCS1.0.24, with TCP Server enabled)

Trying to read the state of the inputs on a KC868-AI via C# with TCP. I've found this article (https://www.kincony.com/smart-controller...tocol.html) but I'm not getting the data they describe.

Whenever I pull digital input 1 to 9 to ground, I read 17 from the socket. Whenever I pull digital input 10 through 48 to ground, I read 18 from the socket.

What is the protocol for TCP on KC868-AI?

Hello everyone ! I have bought some KC868 - A6 modules, a Dwin DMG10600T070 display, which has a configurable RS232 or TTL serial interface port. The screen is powered at 12V and GND is linked to the power and RX - TX communication pins (DB9, pin 2 TX2, pin 3 RX2, pin 5 gnd). When I use the screen simulator and connect the KC868-A6 module to the PC's USB port, the program works perfectly and the communication executes the programmed commands. My query now is how can I program the arduino based KC868-A6 module for RS232 serial communication with the display with the RS232 port that the module has!.

improvement:

add "MOTT feedback all channels" option in webpage setting. Support home bridge.

Enable= MQTT message will feedback all channels state
Disable= MQTT message will feedback single channel

   
   

Can anybody help me with information relating to the ESP32 GPIO pin used to connect the IRQ (nINT) from the PCF8574 (Digital inputs 1 to 6).

I need to be able to capture very irregular (maybe 10 per minute) but short pulses (< 10mS duration) pulses without missing any.

I would hate to have to schedule I2C reads every 5mS or less to make sure nothing is missed.

I have had a look at the KC868-A4 schematic and the DI1-DI4 pins are directly GPIO connect, not through a PCF8574 GPIO extender.

Hi
It's possible to use the bluetooth of the A8 ;
How to have access to bluetooth (esphome, tasmota, KCS); 

Thank you.
