  Troubles UART
Posted by: ksarz - 06-26-2025, 08:54 AM - Forum: KC868-A6 - Replies (12)

Hallo!
I bought a new KC868-A6 (V1.4SP) board.
I will planned work with relays and sensors (temperature and gas concentration). Programming in IDE 2.3.6 (nodeMCU-32S).
Questions.
1. Do I need to update (install firmware)?

2. How can I check the correctness of switching on/off of the relays (6 pcs) and LEDs?

3. Does the KC868-A6 V1.4SP board support UART with a supply voltage of +5 V? The Winsen Electronics ZM106, ZE16B, | MH-Z19B gas sensors that I selected require a supply of +5 V and data exchange only via UART. How can I implement this on the KC868-A6?

4. I2C does not work and cannot be diagnosed. Could this be the problem?

Thanks.

  Question about i2c oled and KCS firmware
Posted by: mumin50 - 06-24-2025, 08:53 AM - Forum: KC868-A16 - Replies (1)

Hi ALL Smile 
My first post.
Want to use KC868-A16 board to do some automation but would like to add Oled on I2C (SSD1306) to show IP adress and some dots representing outputs and inputs
Is there a Source code for KCS v2 firmware so i could add it myself or is it already in? 

Would like to skip rewrite of whole firmware myself  Big Grin

  Help Needed: KC868-A4 Relay Module Integration with Home Assistant
Posted by: mitechlljohnsons - 06-24-2025, 07:32 AM - Forum: KC868-HxB series Smart Controller - Replies (3)

Hi everyone,

I am currently working on a home automation project and just got my hands on the KC868-A4 relay module. First off.., big thanks to KinCony for creating such an affordable and compact board—really impressive stuff !!

I have gone through the official documentation.., but I am still a bit stuck integrating it fully with Home Assistant via MQTT. I have configured my broker and can see some communication.., but the relay toggling seems inconsistent. Sometimes it works, sometimes not. I’m wondering if it’s a timing or topic sap fico training in bangalore formatting issue ??

Can anyone here share their YAML config or best practices for setting up the KC868-A4 with Home Assistant: ?? Also, should I be using Tasmota or stick with the original firmware for more stability: ??

Really appreciate any guidance or even a simple example setup. I am not super advanced but have decent experience with ESP modules and MQTT.

Thanks in advance for any help !!

Mitchel

  AG8 + Daikin AC
Posted by: tenabiker - 06-23-2025, 10:27 AM - Forum: KC868-AG / AG Pro / AG8 / Z1 - Replies (1)

Need some help for Daikin AC control with AG8.

First tried ESP Home firmware using Daikin_ARC  for ESPHome.
Unfortunatelly it was not able to controll the AC Unit.
Them, tried all other Daikin AC for ESP Home (Daikin_BRC and simple Daikin)
None of them worked.

I also flashed AG8 with KCS firmware, but when learning is done, it says SUCEEDED but no code is shown. After trying to send code to AC Unit, it does not work either.

In  the back of AC remote control, it says ARC452A10.

What else can I do ?
