improvement:

1. KC868-COLB default set "enable" for  auto upload function, before version default is "disable".
2. Fixed problem that if have a DS18B20 temperature value auto loaded, other temperature sensors will stop upload, until temperature value changed will auto upload again. Now all DS18B20 temperature sensor will all auto upload.
3. Support use MQTT function by ethernet. it will easy integrate to third-party software, like home assistant, details see our tour: https://www.kincony.com/knowledge/home-assistant


KC868-COLB V1.8 firmware download:
download the ZIP file , unzip update the bin file for KC868-COLB logical controller.

Is it possible to obtain a schematic to be able to fully program the unit with our application? or way to transfer our own binaries to the system?

Thanks and best regards

improvement:
1. Improve the stability of anti-interference, if ethernet line failure by interference , now will automatic restart ethernet chip.

KC868-H32B V4.20 firmware download:
download the ZIP file , unzip update the bin file for KC868-H32B relay controller by USB-RS232 cable.

improvement:
add digital input auto upload function. Now not always to search or read the DI input. when every DI state changed will auto report.

Unzip file , use Bootloader tool update BIN file by USB-RS232 cable.

I am interested in your product to create HomeKit automation to control lightning.
But I have the question - is that possible to use impulse relay output?
Asking that because my home system is build in impulse relay switches 24v to toggle lights. And I am looking for a solution to control that from HomeKit
Thanks in advance for help and suggestions.

this is arduino code for voice module (ESP8266) control by Amazon alexa. it not need use sinric or any third platform. just voice module connect to alexa cloud server directly.
MAX support device number :10pcs. if want to support more, need change the code, or you can use google find out some code solution.
make sure install espalexa.h library file on arduino IDE.

improvement:
add scan device Broadcast command for UDP. This command for software developer scan KC868-COLB in network.

use local network port=4000  send Ansi-String "scan" to remote IP:255.255.255.255 Port:4001
all KC868-COLB in same network device will feedback: device's IP,Port,UID,type
for example:
send->scan
feedback: 192.168.1.200:4196,uid:xxxxxxxxxxxxxxxxxxxxxxxx,type:COLB

now you can weld a RF receiver module (315MHz or 433MHz) with ESP8266 module (voice module).
write some arduino code will support RF sensor decode ,it's easy to integrate RF sensors for trigger any relay output or do scene mode.
   
   
   

MulitiBoardCtrl tool is windows software for PC and tablet. it support use KC868 all relay controller model and all KC868-COL/COLB logical controller. 

1. one software window support MAX 254 device (relay board+COL/COLB board).  
if you add 254 units of KC868-H32B, then you can control total 254*32=8128 channels relay output.

2. we have add the log function, every relay state changed by ON/OFF, will save the data the time to log file.

3. software is open source, write code by visual studio C#. anyone can modify and update it.
