Now writing the program code
       

Hi,

I have installed COL + H32L module to automate home.
however i have problems programming COL, as i cannot get the output on relay 30 when digital input 2 is active.


I see input 2 active, but out 30 never works.

Dear Admin.

How do I change the color (Green, Amber and Red) on the measuring bar as a picture? 
For example, if the temperature is between 30C to 35C it's green and when the temperature is between 36C to 40C is Amber and 41C onwards is Red.

I can't find what the code is and where to place it. 
Could you please show some examples?

Thank you
Subas

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 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.

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.
