KC868-A16 rev1.6 firmware - maurus44 - 04-15-2026

Hello,
I am using a KC868-A16 board (REV: 1.6) and I would like to confirm which firmware is correct for this device.
I have been flashing firmware using the ESP32 Flash Download Tool (v3.9.2). So far, I have tested the following firmware versions:
  • KCS_A16V3_V3.24.3 → I was not able to access the controller after flashing
  • KCS_KC868_A16_V2.2.4 → I could access the controller, but the input table was incomplete / partially missing
At the moment, I am using:
  • KC868_A16_V1.0.10 → this version works, and I can access the controller
My question is:
Am I using the correct firmware for KC868-A16 REV: 1.6, or is there a newer recommended version that is fully compatible?
Thank you in advance for your help!

your board A16 , only use by KCS v2 firmware, KCS v3 firmware use for A16v3 board , that use for ESP32S3 module.
here is newest firmware for your board: https://www.kincony.com/forum/showthread.php?tid=9205

Hello,
Thank you for your help.
I followed your instructions and used the ESP32 Flash Download Tool (v3.9.2) with the following settings:
  • chipType: ESP32
  • workMode: develop
I downloaded and flashed the firmware:
  • KCS_KC868_A16_V2.2.20
Before flashing, I clicked "Erase", and then "Start". After that, I power-cycled the board.
A new Wi-Fi network appeared, and I connected to it. I opened:
http://192.168.4.1/input_setting.htm
I logged in using the default credentials (admin).
However, when I go to the "Input" tab, I see fewer configuration options compared to what is shown in the tutorial video.
My question is:
Did I make a mistake somewhere, or is this normal behavior for this firmware version? I added some pictures.
Thank you in advance for your support.

it's correct. because KCS v2 use by IFTTT. you config digital input with OUTPUT by IFTTT webpage.
you can see KCS v2 online guide firstly: https://www.kincony.com/esp32-kcsv2-firmware.html

RE: KC868-A16 rev1.6 firmware - maurus44 - 04-25-2026

Hello,
I am currently using a Raspberry Pi 4 with Home Assistant installed.
I am working with a Kincony controller and would like to integrate it with Home Assistant.
My main goal is to:
  • Monitor the state of Kincony inputs (digital inputs)
  • Monitor the state of Kincony outputs (relays)
  • Control/change the state of the outputs directly from Home Assistant
At the moment, I am not sure what is the best way to achieve this (e.g., MQTT or another method), and I am also unsure how to correctly set it up so that both input and output states are visible and controllable in Home Assistant.
I would really appreciate any guidance, examples, or documentation.
Thank you in advance!

the easiest way is config by esphome yaml.
