Dear ALL,
I plan to connect via iic PCF8574 - 4 input - 4 output.
Question: How (or) will the KCS firmware find the PCF8574 and connect these input-outputs to the TUYA? I will buy a TUYA license.

improvment:
1. changed process worm momory size.
2. added different delay time when turn ALL relay ON

there are some different files for v1.0.7. delay time: 1ms, 5ms, 10ms, 50ms    4 version.

just added different delay time when turn ON all 32 channel relay output, you can chose by yourself. added the delay time will protect your power system, because if you have connected 32 channel contactor work at the same time,it will cause instantaneous impact on the power grid.

Hi,

Brand new board, I plug it in > the computer doesn't "see" it. What I've tried so far:
- different power sources
- different USB-C data cables
- reinstalled USB drivers
- 3 different computers (all running different versions of macos)
All of the above tested with a working A8 board that I have in use, so it's definitely not the cable/power adapter/drivers.
Another thing that is strange: as soon as I power it up 3 of the four relays engage and stay ON that until I power it off.

Please help. I just want to install Tasmota on it.
Thank you!

   

Nevermind... I tried another random cable and it finally worked! For others who might be in the same situation: I used a USB-A to USB-C cable with a USB-C dongle to plug into the macbook.

I tried to connect atc with h32b and it didnt work, i tried rs232 cable, i tried directly, nothing works how to solve this

1. install USB driver for Windows PC. here is driver download link: 
https://www.kincony.com/download/CH341SER.zip

2. download firmware BIN file (after you download ZIP file , need unzip it):

  m30-factory.zip (Size: 491.68 KB / Downloads: 763)

3. use ESP32 flash download tool:
when open tool, chose "ESP32" chip:
   
then begin do these 5 steps to download firmware:
   
after you downloaded, connect ethernet cable to your router, re power on of M30 board. now the ethernet work with DHCP mode. you can login with your router to find our the M30's IP address,  then use IP address login by web browser.

Is it OK to connect KCOM with power supply 0VDC so that I can simplify my wiring out to sensors?

This way I will only need 3 cores for powered sensors:

• 0V/KCOM,
  
• +12VDC,
  
• Dry Contact Input
  

Hi, could anyone show me how to solve the following?
I have mini server with home assistant and kc868 - A6 with kincony firmware. I'd like to connect the boards via Rs485 and manage relay and DI of kc868 - A6 from home assistant using Rs485.

Do you have an example on how to add multiple devices (i.e. A64, A16, A8) to a mqtt yaml file?

Is it possible to use 24v for power input instead of 12v?

Why aren't binary_sensor entities for mini server appearing even though I followed the same tutorial in the video 

https://www.youtube.com/watch?v=J5GRh7Gk...KinConyIoT

and used the provided codes as shown ?
I kindly request assistance in using these entities
