  KC868-A6 Outputs
Posted by: petez69 - 09-14-2022, 03:25 AM - Forum: KC868-A series and Uair Smart Controller - Replies (5)

Hi Kincony

I have a relayboard that turns relay on when pin goes to GND.  I see A16 digital outputs go high when turned on....Can I invert this to make actuve GND ?

Thankyou..Peter

  [Arduino source code for KC868-A4]-18 one GPIO with multiple DS18B20 sensor
Posted by: admin - 09-14-2022, 01:49 AM - Forum: KC868-A4 - Replies (4)

these 10pcs of DS18B20 temperature sensors work with one ESP32 GPIO. program will print 10 sensor's value at the same time.
   
   
   

Code:
// Include the libraries we need
#include <OneWire.h>
#include <DallasTemperature.h>

// Data wire is plugged into port 2 on the Arduino
#define ONE_WIRE_BUS 13
#define TEMPERATURE_PRECISION 9

// Setup a oneWire instance to communicate with any OneWire devices (not just Maxim/Dallas temperature ICs)
OneWire oneWire(ONE_WIRE_BUS);

// Pass our oneWire reference to Dallas Temperature.
DallasTemperature sensors(&oneWire);

DeviceAddress sensor1,sensor2,sensor3,sensor4,sensor5,sensor6,sensor7,sensor8,sensor9,sensor10;


void setup(void)

  // locate devices on the bus
  Serial.print("Locating devices...");

  Serial.print(sensors.getDeviceCount(), DEC);
  Serial.println(" devices.");

Big Grin [Arduino source code for KC868-A4]-17 homekit work with 4 relay and 4 switch buttons
Posted by: admin - 09-13-2022, 02:51 AM - Forum: KC868-A4 - Replies (8)

this arduino source code for KC868-A4 work with 4 relay and 4 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.
here are KC868-A4 board with 6 gang switch panel (actually I have used 4 buttons) and iPhoneXR.
   

this is demo video:
   

here is source code:

.zip   RealPushButtons-4DO-4DI.zip (Size: 624.09 KB / Downloads: 770)
this is firmware and source code, BIN file included.

if you want to use source code, you should do:
1. install ESP32 V2 board in arduino IDE.
   
2. install "homespan" library for arduino.
   

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.

Photo kincony_kc-H868B_relay32B HomeAssistant Mqtt Not Working After 2022.12.0 Update
Posted by: Shemi - 09-08-2022, 01:27 PM - Forum: KC868-HxB series Smart Controller - Replies (1)

Hi,
I updated HOME ASSISTANT to the latest version and now I get an error message. 
The controller is an H32B model, And the connection is via MQTT.
I can't connect to the controller and nothing is responding, through the HOMEASSISTANT interface.
Before the update I could activate all the relays and see the state of the inputs.


The controller itself works and I can enter the settings through the WEB interface.

This is the message I see in the HOME ASSISTANT interface:
https://im.ge/i/Screenshot-2[img]Manually configured MQTT switch(s) found under platform key switch.[/img]022-09-08-15552800002.OkBDd9



[Image: 72a659600ea6bc80f7ff00799a07540993a558fc.png]


I am attaching a picture of the settings:

[Image: 70496a3eda87726c9a2f3732b93f4167e3db657b.png]



I tried to change the settings to the new format as shown in the instructions and that doesn't work either.

[Image: 159df7bd75704d204ff13ac4286a5dfe7b75fbc3.png]

I assume the problem stems from incorrect settings in the CONFIGURATION.YAML file.
The format should probably be changed.
I would love to get help please.

Thanks in advance,
Shemi Cohen

  Poor IR transmitter range
Posted by: onlyoneme - 09-08-2022, 11:13 AM - Forum: KC868-AG / AG Pro / AG8 / Z1 - Replies (3)

Hello, I've just bought this device and after some preliminary tests I've noticed that IR range is terribly poor comparing to my another transmitter, which is a cheap Tuya based device.

Is it a matter of weak IR LEDs or reason is something else?
