I bought this base.
The program will learn from this.
I want to build an environment for attachments.
Please guide me.

Greetings from USA--- I have KC868-H32B Controller with Switch Terminal Board v.2.1.  Controlling 13 outdoor lights, not using remainder relays currently.  Yesterday 2 October, system stopped being responsive to either inputs from app on phone, from remote control, and from push buttons.  Lights that were on before failure remain on, lights which are off can not be turned on.  

I have tried power on/off and I think it is possible the switch terminal board failed since I tested by first removing all loads and also tried to toggle relay by making contact on switch terminal board common + relay and nothing happens.   I have not been able to ever do a firmware update since I do not have Serial to USB cable, but I wonder if it is unrelated to firmware.  Does anyone have similar experience?  Anyone ever have Switch Terminal Board fail?[url=https://www.kincony.com/forum/showthread.php?tid=2320&action=lastpost][/url]

Thank you for your help!

hello!

I have COLB connected with home assistant by mqtt, when i restart home assistant all sensors turn to "unknown" to see the state again i have to restart COLB.
What have to do to maintain the state?

Hello Guys,

I have KC868 Server connected to HA by mqtt, i can read the entities and works well, in the relay board i connect 5 different lights also i add a wall switch which i connected to relay board and make an automation in HA to read the state of lights.
To connect relay and HA i manually add code to configuration yaml file.

My problem is that i have errors since i add switch code to yaml file. what im doing wrong??
Keep in mind that the automation works but when i press the button it has a delay 3 sec until light on

this is log details

Error parsing value: ‘dict object’ has no attribute ‘sw12’ (value: {“relay1”:{“on”:1},“relay2”:{“on”:1},“relay3”:{“on”:1},“relay4”:{“on”:1},“relay5”:{“on”:0},“relay6”:{“on”:0},“relay7”:{“on”:0},“relay8”:{“on”:0},“relay9”:{“on”:0},“relay10”:{“on”:0},“relay11”:{“on”:0},“relay12”:{“on”:0},“relay13”:{“on”:0},“relay14”:{“on”:0},“relay15”:{“on”:0},“relay16”:{“on”:0},“input1”:{“on”:0},“input2”:{“on”:0},“input3”:{“on”:0},“input4”:{“on”:0},“input5”:{“on”:0},“input6”:{“on”:0},“input7”:{“on”:0},“input8”:{“on”:0},“analog1”:{“value”:0},“analog2”:{“value”:0},“analog3”:{“value”:1},“analog4”:{“value”:1}}, template: {{ value_json.sw12.on }})

this arduino source code for KC868-E16S/KC868-E16T work with 16 relay and 16 momentary switch buttons via Apple homekit app. you can download the BIN firmware directly without chanage any code. Or you can open arduino source code project to compile. The source code use homespan library, mainly use PCF8574 extend GPIOs work with homespan.
   
       

here is firmware BIN file for KC868-E16S/KC868-E16T:

  RealPushButtons.ino.nodemcu-32s-BIN.zip (Size: 623.62 KB / Downloads: 730)
here is arduino source code via homekit homespan library:

  RealPushButtons.zip (Size: 2.49 KB / Downloads: 747)

after you downloaded firmware, how to use:

1. power on of your KC868-E16S/KC868-E16T board , connect with USB cable with your PC.
   
find out your USB cable COM port.

   
Set COM port in your arduino IDE "Tool" menu

   
open "Serial Monitor", actually you can use any serial monitor tool, we use arduino , just to use it's "Serial Monitor"

after you downloaded firmware, first time to use, need type "W" in serial monitor, chose number of wifi SSID, input password. 
   
   
   
   

then use your iPhone or iPad to pair KC868-A4.
                                    
if you want to eraser all data , re-config homespan, then you can send "E" to serial port.
   

I am using kincony a16 with 16 relay board with esphome running but at the boot time all the relays  toggle  and make the relays on and off ...is their a way to stop this in the software side..this is become a big problem for me due all the appliance connect to relays suddenly become active and then turn off at the a16 booting up....below is my config

i have used on board extend serial port. actually use want to use VCC,GND,RXD,TXD for Nextion display.

define RXD:GPIO13 TXD:GPIO12 by ESP32

weld Vcc 5V from LM1117 output pin.

here are some photos:

   
   
   

This just a simplest demo, use Nextion display two buttons, press button-one will send 'a' by serial port, press button-two will send 'b' by serial port.
when KC868-A4 received 'a' will turn ON relay1, when received 'b' will turn OFF relay1.

firstly create two buttons UI by Nextion Editor PC software:
   
   

here is firmware BIN file, you can download to KC868-A4 ESP32 directly to use:


  nextion_KC868-A6.ino.nodemcu-32s.zip (Size: 108.86 KB / Downloads: 769)
here are source code:

improvement:
support set "interlock" mode for motor curtain. Because it make the logical by hardware, so it will be safety. when set relay in "interlock" mode, in group relay will never ON together at the same time.
