Here is download tool, you can connect with USB-RS485 adapter, work with 38400 Baud rate.
   
first, let your USB-RS485 adapter connect to KC868-HA by RS485 "A" and "B"


step1- change Baud rate to 38400
step2- "Open Port"
step3- power on of your KC868-HA, then RED LED on board will blink, must during blink time, press the button "bootloader Detect", pc software will detect the board.
step4- Open File, chose your BIN file. Note: you downloaded is ZIP file, you need to unzip, then will find the BIN file.
step5- Press "Download" button, begin download
step6- Click "Run" or re-power on of your KC868-HA will begin work.

KC868-HA can be used with KC868-A8S module?
What is the type of communication over RS485.
Do you have some sample Arduino IDE code to use the KC868-HA button module.

My Next Question.
How the digital inputs on the KC868-HA button module are used in cooperation with the KC868-H32B Pro, how they are displayed in Homekit with the firmware downloaded from the kincony website.
Can I use one module of buttons with relay and one module as Digital input example motion detect?

This is a special firmware version, if you want to use 32 channel (SW1--SW32 - green terminal) + 2 channel (ALL ON, ALL OFF - orange terminal) + 6 channel (sensor input ports - blue terminal) feedback ON/OFF state by MQTT message, you can update this firmware for KC868-H32BS smart controller.

Hello,

is it possible to somehow speed up sending statuses via MQTT to Home Assistant? I have the Tasmota firmware installed on the Kincony KC868-A8-v1.5, and if I switch on a relay via the web interface, the change of state is written to me immediately. The problem is with Digital inputs, which are sent in up to 4 minutes. The Tasmota firmware is yours modified in version 10.0.0.3

Thank you for your response

Hi

I'm using H32B with switch terminal board. I connected a push button/switch to the switch terminal board. It is controlling perfectly the relay.

The problem/bug/issue I have is the following:

- Initial status all relays off. I query the relay status over HTTP with "http://192.168.1.9/sw_ctl.cgi?RelayFF=RD&postpwd=<myversecurepw>". It shows all relays off.
- I push the button to turn on relay on. The relay turns on.
- Then I query the relay status again with the same HTTP command but still shows off!!! but the relay is physically ON.
- If I change the relay status over HTTP command (ON/OFF) and query again over HTTP command as above then it is reporting the relay status properly over the HTTP command.

I can also reproduce the same with any of the relay outputs.

Can you have a look on this? Maybe a firmware bug?

thanks.

find that file, replace SDA and SCL with your board's.
   

Hello,

I want to use the outputs of a KC868-A8 to control 8 of my heating valves. They require 230V and not too much power, this should work fine.

However, I would like to use the inputs to read the state of the wall thermostats. These are usually connected directly to the valves, and are therefore delivering 230V if closed. Can you recommend a good way how I could connect these to the KC868-A8 inputs?

Thanks you!

We have designed the new version of "switch terminal board" -- KC868-AK. This is a powerful ESP32 programmable keyborad , support by home assistant via ESPHome for home automation DIYer. It also can work with KinCony's smart relay controller. let your wall switch panel can work with "1-click" , "2-click" and "hold on" actions.
