I have a KC868-A16S with the following code on it , After installing it it now will not respond,
the relays will only activate via the on board push button not via home assistant interface?
Home assistant show the switch turn on but the board does nothing.

I there any suggestion why this is happing ?

Dose the code look ok and can I reset the board and reload the firmware.

I'm trying to program four momentary switch via bluetooth commands. I don't understand why I can't enable  "Relay3".
To compile KC868-A4 code I'm using "Arduino IDE". To program Android code  "MIT App Inventory" .
 Here is the codes I Used.  Can some one help me to understand where is a mistake ? Tank You.

AI Code     

Arduino IDE Code:

#include "BluetoothSerial.h"
BluetoothSerial SerialBT; // RX | TX
int Relay1 = 2;
int Relay2 = 5;
int Relay3 = 15;
int Relay4 = 4;
void setup() {
  pinMode(Relay1, OUTPUT);
  pinMode(Relay2, OUTPUT);
  pinMode(Relay3, OUTPUT);
  pinMode(Relay4, OUTPUT);
 
  Serial.begin(19200);   // Serial monitor
  SerialBT.begin(19200); // Bluetooth serial communication
 
  Serial.println("Bluetooth Control for KC868-A4 Relays");
}
void loop() {
  if (SerialBT.available()) {
    char command = SerialBT.read();
   
    // Command format: '1' to '4' for relays 1 to 4
    if (command >= '1' && command <= '4') {
      int relay = command - '1' + 2; // Calculate the relay control pin
         
      digitalWrite(relay, !digitalRead(relay));
   
      Serial.print("Relay ");
      Serial.print(command);
      Serial.print(" is ");
      Serial.println(digitalRead(relay) ? "ON" : "OFF");
    }
  }
}

Hello, 


I can use a flux sensor in KC868-A16S in ports AI1-AI4?

I think sensor use pulses.


Thanks

Hello, I am an IoT Maker and I would like to ask regarding the KC868-AG IR Controller:
1. What software do I get with the device when I purchase it?
2. Does the software come in source code? I am asking this as I would like to develop my own code for the device (extend its capabilities)
3. Is there a version of the device with just only its IR capabilities (no need for RF433) for a reduced price? I only need its IR capabilities to control my AC and other IR controlled devices at home
Thanks a lot!

Hi everyone, I need to know which screws to buy to be able to fix the card directly to the back of the box (as indicated in the photo). I need to remove the front part of the box because in the European control panel the default box does not fit, it does not allow it to be closed correctly, so I have to find the correct screws to be able to do it. I attach photos. Thank you

Hi Kincony,

I am building a new house and looking to use Kincony products to control lighting only. Well, maybe some aspects of security as well.

Differences from a usual case are:
1. Not interested in any existing home automation software, I want to write my own software in Arduino to do specific tasks only.
2. Not interested in things like Wifi control, phone apps etc etc. Mostly for it to work standalone.
3. Also not interested in 4G, voice controls etc etc.

I want to use wireless light switches only, for my own reasons. They can be Zigbee or RF433 from what I see sold on Aliexpress. I would like to have them talk to one central wireless hub that either talks to the central controller or is a central controller itself. 
Estimating <32 line outputs for lights, so probably using something like 2x KC868-E16V2 would work?

Can you recommend a suitable Kincony product(s) for this case and are there enough examples on how to work with Zigbee or RF433 and Kincony?

Many thanks,
Jack

Hello,
Since a few days I have been having problems with the analog outputs on my KC868-AIO. (KC868-AIO-EXTAO--V1.2)
channels 1 to 6 work normally
Channels 7 and 8 are off and no longer respond to anything. (the LEDs on the PCB are also off. With a voltmeter I measure 0V on the output)
channel 9 works normally.
Channels 10 and 11 are off and no longer respond to anything. (the LEDs on the PCB burn at 100%. With a voltmeter I measure 11.72V on the output)
When other channels are at 100% I measure 10.2V on the output.
channels 12 to 16 work normally.
When I disconnect all outputs, the above remains the same.
All other inputs and outputs work normally.

I have no idea what happened.
My configuration has not changed.
All outputs are connected to the exact same type of dimmers.

What else can I test?
Is there something wrong with the "KC868-AIO-EXTAO--V1.2" board?

Thank you in advance!
   
   

Hi,

I've been strugeling with a calibration issue.

Hello engineer 

Now I am trying to use Modbus by kc868-server and kc868-HAV2

I can send orders  on and off by injecting node-red as attached photo 

 how can I make node control on and off kc868-server by kc868-HAv2 throw node-red

I received the board yesterday and start trying. The wifi state led blinks when its looking for conection, but after connect the led turn off, the switchs on Tuya app does not respond. After clean wifi config and connect again the app shows the switchs at the last change I did, and the wifi led star on and turn off after couple seconds. At the Tuya app shows all 32 switchs and the digital the inputs correct.
