  [arduino code examples for F32]-01 Turn ON/OFF relay
Posted by: admin - 11-03-2025, 11:25 PM - Forum: F32 - No Replies

Code:
/*
* Made by KinCony IoT: https://www.kincony.com
*
* This program controls a 32-channel relay board via two PCF8575 I/O expanders.
* It sequentially turns on each relay and then turns them off in a loop.
*
* Pin Definitions:
* - SDA: GPIO 8
* - SCL: GPIO 18
*
* Delay Time:
* - 200 milliseconds between switching relays

  Using KC868_A8 as switch
Posted by: dco333 - 11-02-2025, 03:52 PM - Forum: KC868-A8 - Replies (3)

Hi

I want to use the board as a switch with the relays.
I have installed KCS Firmware 2.2.14 and activated MQTT to my MQTT broker on Home Assistant.
I followed the instructions with the configuration.yaml File and also replaced all serials by mine.
I can see the switches in HomeAssistant. But when I push the switches, nothing happens on the board. No relay is clicking.

I think I missed something. What else do I have to configure in the KCS Firmware Gui to switch the relays?
I've read many tutorials, intructions and so on, but I don't understand it how to switch the relays.
Also in the KCS Gui I didn't find any switches to test is.
I think, there has to be configured more in the firmware.

I hope to get any adice from you.

Regards

  Update ESPHome-Firmware 2023.12.9 -> 2025.10.1
Posted by: Nobby888 - 11-02-2025, 03:01 PM - Forum: KC868-E16S/E16P - Replies (1)

Hi Community,

friend of mine had ordered a Tiny House and long story short: she was left alone with her automation in HomeAssistant.

First Problem:
- she got screwed with the server. HomeAssistant-OS (HAOS) didn't work and we couldn't reinstall it, because the PC was toast. So we ordered a new Mini-PC (with an Intel N150, 8GB Ram and 500GB NVMe-SSD) and installed HAOS (Version 2025.something) and HACS. We installed the Backup-File (stored on Google) and because there was already a version-gap from 2023 (the time they originally installed HomeAssistant) and 2025 (the time we are trying to fix it) I wanted to update the whole system and the modules in HAOS.

And now the probelm:
I want to update the ESPHome firmware of the KC868-E16S over OTA. Because of the Version-gap between ESPHome-Builder and the Frimware of the relay-module the integration doesn't work properly in HAOS.

Hardware: KC868-E16S
The Version of ESP Home Builder: 2025.10.1
The Version of the ESP Home Firmware 2023.12.9


I found out, that there are a lot of changes over the time, so I already made some changes in the original YAML-File (see attachet):
- adding on OTA: platform: esphome
- changed "dallas" to "one-wire"
but I could not make an OTA.

After trying to make an OTA I get the attachet message.
   

Please help! What am I doing wrong? What am I missing? Could you please correct the YAML-file?!
And please avoid: "Why did you update?! Never touch a running system ... well, it wasn't running and I like an up-to-date-system"

Thank you so much for your help!!

I’ve recently got this board and intend to use it for operating several valves.
Could someone confirm if it’s possible to run 24 VAC through the output channels?
Thanks in advance!

  Request for Technical Support – Controlling KC868-A8 Relays via Physical Buttons
Posted by: sson6203 - 10-31-2025, 08:47 AM - Forum: KC868-A8 - Replies (1)

1. 현재 설정
현재 MQTT 와 HTTP 명령을 통해 KC868-A8 장치 의 릴레이를 제어하고 있습니다 .
(설치는 사진 1 에 표시된 지침에 따라 수행되었습니다 .)


2. 목표
물리적인 푸시 버튼을 사용하여 각 릴레이 채널(CH1~CH8)을 제어하고 싶습니다 .
물리적 버튼을 누르면 해당 릴레이가 토글되어야 하며, MQTT 상태도 그에 따라 업데이트되어 Home Assistant(HA) 토글도 실시간으로 변경되어야 합니다.


3. 문제 이를 달성하기 위해 여러 Arduino IDE 스케치를 시도했지만( 사진 2~7
참조 ) 컴파일 타임 오류가 발생했습니다.

========================
#error 이 코드는 ESP32 플랫폼에서 실행되도록 설계되었습니다! 도구->보드 설정을 확인하세요.
종료 상태 1
========================


보드 설정을 올바르게 구성하는 방법이나 MQTT 작업과 함께 물리적 버튼 제어를 구현하는 방법을 잘 모르겠습니다.



4. 요청
다음 사항에 대한 단계별 지침(초보자 수준)을 제공해 주세요 .

  KC868-A16 - IP & PORT ?? Important !!!
Posted by: Guele1 - 10-29-2025, 07:28 PM - Forum: KC868-A16 - Replies (22)

KC868-A16 - IP & PORT ?? Important !!!

I would like to control my KC868-A16 (V1.6) module using my mobile phone within my local network (without Internet access).
When setting up the "K-Box Smart" (version 2.0.9) software, I’m asked to enter the IP address and PORT XXXX
The module is connected via LAN cable to my Fritz!Box 7530 router.
I was able to find the IP address in the router menu, but I’m not sure which port number I should enter in the app or where to find it.
Could someone please explain:

which port I should use for the KC868-A16, and
whether a port configuration is needed in the Fritz!Box
if I only want to use the system within my local network (without Internet access)?

Thank you very much for your support!

Best regards,
Günter Lehner
