KC868-COL support use analog sensor that 0-5V output, if you already have 4-20mA sensor. you can use a 250 Ohm resistance connect with signal input port and GND to convert.

To convert a mA analog input signal to voltage you need to attach a inline resistor. The size of your resistor will determine the output range of your voltage. 

Resistor Calculations are as follows:

Using ohms law V = R(I)  (Voltage = Resistance * Current)


If we were to scale a 4-20mA to 1-5V

For the 0 Value: .004 Amps * 250 ohms = 1 Volt

For the Max Value: .20 Amps * 250 ohms = 5 Volts

How to add RF light switch with KC868-G to SmartHome app?

Hello, I bought the component to connect Alexa to my Home Domotic. Does it is possible to change the luminosity of the light? In Sinric or Alexa application I can change the luminosity, but from Alexa serial interface I read only RELAY-SET-255,2,1 (for ON) or RELAY-SET-255,2,0 (for OFF).
The KC868-Hx Alexa Voice Module does not change the "value", for example from 255 to 125 for 50% of luminosity. 
How it is possible to send the "value" to the serial port?

Thanks in advance

Massimo

KC868-H32 relay controller PC software add "auto off" option. If enable this option, when you press "ON" button, will auto OFF after 2 seconds.
update version V20201119
download link: https://www.kincony.com/download/PC-KC868-H32B.zip

KC868 relay controller integrate to domoticz soon making the plugin file. It will support by KC868-H32,KC868-H16,KC868-H8,KC868-H4,KC868-H2 all relay controller.

we have recorded many videos will help you.

1. How to wire? you need to know the hardware interface and diagram.

10. If you already have one user account of mobile phone, but more people want to use.Then you can use grant authorization function to share deivce.(Note: one controller only can add to one phone account)

11. If you want to relay controller's input port trigger output. Such as input 1 -> relay1 ON,relay2 OFF.
  step-1: create the scene for relay output actions.  https://youtu.be/XzfLEUbYxI0
  step-2: set input port trigger with which scene you have created.(Note:when you press relay for ON/OFF,must press the relay name text position when save)  https://youtu.be/-JuWCZC39rY

12. If you want to relay controller's input port trigger for a alarm message send to all user.

Somebody try register new account on existing controller, where I already registerd. After open app. how they can see my controller, and other definitions.

Do you plan make automatic refreshing switch states on mobile and PC application. When both application running and change for example relay over mobile it not automatic refresh on PC display. I see it can manually 'refresh' but it should be better if all application synchronized every some seconds automatically.

I try to development software for connect and turn ON/OFF relay
I can connect with Local network 
but I need to connect outside network 
I have public IP server for install or config but I don't know how to config
And I develop Software with Java language



when I connect with Local network I config at attachments
