Hi

Do you have a diagram for the number arrangement of relays on the board. 
Which one is 1... 32

I can't see all the numbers on the board

Hi 
I am interested in KC868-A32 to use as a central module with some assistant

I am trying to:
1-control multiple 24V DC LEDs
2-Control an irrigation system
3-connect door/window sensors, motion sensors and other sensors

questions:

1- can this be achieved with one A32 board?
2- wiring the LED (24V DC) to the relay output, I need help with. I will use Mean Well 24V DIN rail mounted power source for the LEDs
3- can I run the irrigation system on the same board? can you give me some direction on this if possible

I will be sing ESPhome
Thank you

Hi,

What is the name of the white I2C connector used on the board if I want to purchase them to make up cables?

Can I use any I2C bus address I choose or is the white connector bus shared with the pcf8574 expanders so I must avoid 0x23, 0x24,0x25 and 0x26?

Thanks!

It seems that my outputs are not working (no leds, no voltage change).

I measured the voltage on the optocuplers and its ~1.1 V beetween optoupler legs (as on image):

   

I tride official firmware and esphome, both are responding to commands (on = 1.1V, off = 0.0V)

Can I connect an RS232 or TTL display directly to the KC868-A16, or do I need to use an adapter to connect it to RS485?

Hello,

I would like to get one KC868-A4 sample for educational purposes.

Here is "KCS" firmware for KinCony M30 AC energy meter board.

  KCS_M30_V2.4.7.zip (Size: 733.5 KB / Downloads: 66)
make sure your M30 ARM CPU firmware >= M30_KU_V10_240904SP

here is link for ARM CPU firmware: 

  M30_KU_V10_240904SP.zip (Size: 9.7 KB / Downloads: 53)
KinCony ARM CPU download tool:

  KC868 Controller Bootloader.zip (Size: 8.56 KB / Downloads: 51)
use USB-RS485 adapter to update ARM CPU, make sure baud set to 38400bps.
   

v2.4.7 improment:
1. support display power with negative. support use for "generator", power feedback to power grid.
   

Hi,

I want to install DS18B20 sensor and use it instead of analog temperature sensor which is not accurate.
Will be using one of the gpio on the white serial port. 

As kcs firmware does not support A32 with DS18B20 sensor, how to make it work.
I can write arudino code to get the temperature if needed, but how can it be use together with kcs firmware?
Need some help. Thank you.

here is KinCony firmware for ALR LoRa board - ALR. it support control relay , monitor DS18B20 temperature and 4 channel analog input, 1 channel digital input state in home assistant by MQTT. You not need config any code for home assistant yaml. Because we have design firmware enabled MQTT auto discovery for home assistant.
   

here are two ALR board.  one work as RECEIVER(gateway), another work as TRANSMIT(read sensor state, control relay), just set DIP switch on PCB, let two board same DIP state, so that they will communication with each other, easy!

   

RECEIVER(gateway) board's LCD displayer will show MQTT broker connection state, LoRa signal value and how many LoRa package have received.
TRANSMIT board's LCD displayer will show DS18B20 temperature value,  LoRa signal value and how many LoRa package have sent.

   

here is two firmware BIN file for different board:
for RECEIVER board:
  ALR-RECEIVER-20240904.ino.merged.zip (Size: 614.04 KB / Downloads: 52)
for TRANSMIT board: 
  ALR-TRANSMIT_20240904.ino.merged.zip (Size: 606.17 KB / Downloads: 49)

download firmware by ESP32 DOWNLOAD TOOL:
   
chose ESP32-S3 and USB mode.

   
chose RECEIVER board's firmware and set address to 0x0

   
chose TRANSMIT board's firmware and set address to 0x0

set router's wifi ssid, password, mqtt broker ip, mqtt port, mqtt username, mqtt password for RECEIVER board via USB-C cable.

config json command:
{
  "wifi_name":"KinCony",
  "wifi_psw":"a12345678",
  "mqtt_ip":"192.168.3.124",
  "mqtt_port":"1883",
  "mqtt_user":"mqtt",
  "mqtt_psw":"123"
}

   
serial port debug tool download:

  UartAssist.zip (Size: 468.4 KB / Downloads: 49)

after config complete and reboot. you can see KinCony ALR board is showed on home assistant DEVICE list:
   

you can add these entities to home assistant dashboard.
   

Hi, I Have just purchased a KC868 A6 unit and would like to see a user guide on how to connect to this device and upload a program to it from Arduino IDE.

I've tried searching but have not yet found a user guide for the A6.

Thank You
