Hi there

I'm having an issue with getting the KC868-A6 RTC working.

I've taken the example code in the A6 thread as per below, and it returns an error of "Couldn't find RTC".

I've made sure that the I2C SDA and SCL pins are set correctly in the NodeMCU-32S config file.

The RTClib I've used is the Adafruit library below:
https://github.com/adafruit/RTClib

The battery has been installed into the socket on the board.  I've successfully coded up things so that the PCF8574 outputs and inputs to work so I know that the I2C SDA and SCL are working.

The comments in the example code mention the Wire lib, so I've tried including this as well, but it didn't fix the problem.

Any thoughts would be appreciated.


/*KC868-A6 DS1307 CODE*/
// Date and time functions using a DS1307 RTC connected via I2C and Wire lib
#include "RTClib.h"

RTC_DS1307 rtc;

char daysOfTheWeek[7][12] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};

void setup () {
  Serial.begin(115200);

#ifndef ESP8266
  while (!Serial); // wait for serial port to connect. Needed for native USB
#endif

  if (! rtc.begin()) {
    Serial.println("Couldn't find RTC");
    Serial.flush();
    while (1) delay(10);
  }

  if (! rtc.isrunning()) {
    Serial.println("RTC is NOT running, let's set the time!");
    // When time needs to be set on a new device, or after a power loss, the
    // following line sets the RTC to the date & time this sketch was compiled
    rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
    // This line sets the RTC with an explicit date & time, for example to set
    // January 21, 2014 at 3am you would call:
    // rtc.adjust(DateTime(2014, 1, 21, 3, 0, 0));
  }

  // When time needs to be re-set on a previously configured device, the
  // following line sets the RTC to the date & time this sketch was compiled
  // rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
  // This line sets the RTC with an explicit date & time, for example to set
  // January 21, 2014 at 3am you would call:
  // rtc.adjust(DateTime(2014, 1, 21, 3, 0, 0));
}

void loop () {
    DateTime now = rtc.now();

    Serial.print(now.year(), DEC);
    Serial.print('/');
    Serial.print(now.month(), DEC);
    Serial.print('/');
    Serial.print(now.day(), DEC);

    Serial.print(" since midnight 1/1/1970 = ");
    Serial.print(now.unixtime());
    Serial.print("s = ");
    Serial.print(now.unixtime() / 86400L);
    Serial.println("d");

    // calculate a date which is 7 days, 12 hours, 30 minutes, and 6 seconds into the future
    DateTime future (now + TimeSpan(7,12,30,6));

    Serial.print(" now + 7d + 12h + 30m + 6s: ");

We have designed KC868-E8T with Tuya module , 4G LTE module and ESP32, the 8 channel removable relay board.

You can integrate KC868-E8T to home assistant by ESPHome use follow resource:

a. 8 relay relay, 8 channel digital input for switch panel. 4 channel AC220V energy meter (BL0939 energy chip) for load's voltage, current, power, power consumption. DS18B20 temperature sensor.

b. support use Tuya mobile phone application remote control 8 relay by internet , monitor 4 channel load's energy meter and temperature by DS18B20 sensor.

Hello.

I need to know how to completely reset the H23B, Seria number H32B200812520, I don´t have access to it and I can´t configure it for WEB access.
It´s very old firmware, and never been done, which if you have i want update.
I couldn´t find the manual or the PC software on the website kincony.
Thanks

Hi there
I'm trying to get the relays to work on a KC868-A6.
I'm using the KC868-A8 example source code as the basis for this and modified it as shown below:

#include “Arduino.h”
#include “PCF8574.h”

#define I2C_RELAYS_ADR 0x24
PCF8574 pcf(I2C_RELAYS_ADR);

void setup() {
Serial.begin(115200);
Serial.println(F(“Start Kincony KC868-A6 Relays example…”));
pcf.pinMode(P0, OUTPUT);
pcf.pinMode(P1, OUTPUT);
pcf.pinMode(P2, OUTPUT);
pcf.pinMode(P3, OUTPUT);
pcf.pinMode(P4, OUTPUT);
pcf.pinMode(P5, OUTPUT);
Serial.print(“Init PCF8574… “);
if (pcf.begin()){Serial.println(F(“Ok”));}
else {Serial.println(F(“Error”));}
}

void loop() {
pcf.digitalWrite(P0, HIGH);
Serial.print(F(“Relay #”)); Serial.print(P0); Serial.println(F(” ON”));
delay(10000);
pcf.digitalWrite(P0, LOW);
Serial.print(F(“Relay #”)); Serial.print(P0); Serial.println(F(” OFF”));
delay(10000);
}


Using this example, the pcf.begin statement fails and returns "Error".
Looking at the schematic diagram for the KC868-A6, the I2C SDA is set to pin 26, and the SCL is set to pin 23.  By default the PCF8574 library will default to other values, so I tried changing the statement below to the following which matches the format noted in the readme file for the PCF8574 library
 PCF8574 pcf(0x24, 26, 23);

This didn't work either and so I tried the various I2C scanners and they don't find any I2C device.

I've also ensured that the relevant pins_arduino.h file has been edited to reflect the correct SDA and SCL pin values.

One other thing I have noticed is on startup there is a strange error, see below:

The highlighted line in red looks odd but I can't find anything online to help. 

Any assistance would be appreciated.

Hi

I would like to have a wall switch status monitored in Home Assistant using Node Red to do automation.  I have this configured and working as per the 4-Wall Switch Wireless remoter video.  I can see the button state change in Node Red using the debug option.
 
However the default behaviour without any programming is for the switch buttons to control the corresponding H16B relays, switch button 1-16 control H16B relays 1-16 directly.
 
After I configured Node Red in HA I can make Switch button 1 turn on H16B relay 2 but is also turns on relay 1, (by default).
 
Is there a way to turn off this default setting so the switch buttons don’t change the H16B relay states unless I configure it in Node Red?
 
Set up is
HA running Node Red
KC868-H16B V4.34  Work Mode: TCP Server for both Ethernet and Wifi
Switch Terminal Board V2.1 connect via Rs232
6 Gang Wall Self Reset Momentary Switch Toggle Button Dry Contact.  Connect via KCom and K1-K6

Any help would be appreciated.

Hey,

i am interested in a tutorial showing how to make multiple esphome kincony devices talk to each other over rs485. is this possible?

i know that you actually do it via homeassistant - but this way it is failsafe.



and the other thing what i want to do is connect a dmx interface via rs485.

https://github.com/andyboeh/esphome-dmx512

is that possible with esphome and the kincony rs485?

Are there any examples of how to use the A32 board with an I2C device?  I have 5  SHT30 I2C Temp/Humidity Sensors that I have connected to an ESP32 Dev board and working.  I've upgraded to thge A32 board as everything is integrated but I'm confused how to wire the sensors to the A32 board and read the values. I cannot find documentation that shows how to wire into the GIO pin on the A32 board.   Do you have any example code and/or wiring diagrams on how to connect  these?  Thank you in advance for any advice

Hello!

I have a TV, a stereo and a fan with different remotes.

1) How i can make KC868-AG "learn" the remotes.
2) How i integrade them with home assistant.

I saw your video with A/C and i want to do the same with the other devices
