How to Produce KC868-H32's PCB:


Following is the introduction and solutions of KC868-H8/KC868-H32 controller which we plan to introduce in January-December 2019 on "Radio Magazine" in China. There are only Chinese language,but some of them will be translated into English language. You can visit our website for viewing.We will continue to update.

This is a sample code for Turn ON/Off 's Hello World demo.

This is anlysis KC868-H32&KC868-H8 Controller's communication protocol

how to remote control relay by http string

This is smart lighting control system implementation case

We also writed some kinds of Smart Home DIY books to help people learn IOT knowledge.

Software Operation (For Engineer Development)

1. Opening the network debugging tool to detect the IP address and port of the device (see below figure)

2. Clicking【Device】, see below figure


3. Double clicking 【the Name】, set up the network parameter of the device


4. Choosing the working mode, TCP is for local area network setting or secondary  development; UDP is for APP controlling.

Secondary Development Communication Protocol

1. Relay Controlling(SET):


 RETURN: RELAY-SET-x(1bytepack_num),x(1byterelayserialnumber),x(1byteaction0/1),



 2. Relay Status(READ):


RETURN: RELAY-READ-x(1bytepack_num),x(1byterelayserialnumber),x(1bytestatus0/1),OK/ERROR


3. Input Status(GET_INPUT):


RETURN: RELAY-GET_INPUT-x(1bytepack_num),x(1bytestatus),OK/ERROR

Secondary Development Program Toolkit

We supply complete source program Toolkit of VS2005(Microsoft Visual Studio 2005) , and we give the controlling examples through RS232 serial port and Ethernet socket,to help customers carrying on the secondary development.

The PC software can control the relay switch and also show the input state.Details showed from below screenshots.


We can supply the DEMO code of C++Builder, Delphi, VB.Net, Python and iOS versoins.
