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.

improvement:

1. add read input state http command for developer integrate to third-party software. you can send http command to get information of 6 channel digital input port state.

Command is like this, send:  http://192.168.1.xx/sw_ctl.cgi?RelayFF=RD&postpwd=XXXXXX
Then will feedback all state.

2. support use MQTT function by WiFi. it will easy integrate to third-party software, like home assistant...
how to integrate to home assistant by MQTT, see this link: https://www.kincony.com/kc868-h32b-integ...-mqtt.html

3. add option on config webpage, you can chose whether relay will remember the state before power off. Just whether receover relay sate when power on.

4. add option on config webpage, you can chose any relay channel for momentary work mode, and set the delay time for auto off.

HI, CAN I USE ONE KC868 COLB TO manage multiple Relay boards. for example :
Am working on a project that needs multiple KC686-H32B Relay assembly.
and i want to use one KC868 COLB to drive up to 2 units of KC686-H16 and i unit of KC686-H32 located at different remote location from each other.

The power outlet products, with the same style as switch panel products, are used together with switch. You can DIY smart home automation by different color style as you like.  

Hello. I am new to the forum, I have just installed a KC868 H16B controller, I managed to control it remotely with a 4G router, it works fine.
Now I want to install it on a remote site powered by solar panels, to manage my watering system.
I have several questions: how to create timers for each output? How to activate inputs from a contact, I would like to activate an input from a dry contact, and this input will activate an output. Is this possible?
I have ordered a HC868-COL B, I will set it up and associate it with the H16B. If you can help me please.

Is it possible to configure this module so that every time a pulse occurs on switch 1, the status of relay 1 is changed?
Like this video https://youtu.be/HlxVVIB2yXk

I need this to happen on the device independent of network connectivity, so each device can be a standalone unit.


I will use Home-Assistant with Node-Red. However, if I depend on Node-Red for this, i have the risk of not being able to light a lamp locally if my HA is unavailable.

Thank You

Marcio

Are there any adapter plates that will allow these switches to be mounted in a standard 4X4 American wall box?
