What we will need:
– MPDMv4 Universal AC Dimmer – available also on Tindie Store !
– Raspberry PI 2 Board
– Domoticz
Latest available, on a Raspberry PI 2 Board install :  

      sudo curl -L install.domoticz.com | bash

Software 

1. PIGPIO library for Raspberry PI install script:

rm pigpio.zip
sudo rm -rf PIGPIO
wget abyz.co.uk/rpi/pigpio/pigpio.zip
unzip pigpio.zip
cd PIGPIO
make -j4
sudo make install

save it in the choosen directory for your PIGPIO library as “install.sh” and run also command:

chmod 775 install.sh

2. Testing script:

#!/usr/bin/env python

#*** MPDMv4 Universal AC Dimmer PWM Example  ****************
#*                                                          *
#* This demo is using RPi2 GPIO18 (header pin 12)!!         *
#*                                                          *
#* Wiring table:                                            *
#* MPDMv4      Raspberry PI 2                               *
#*   VCNT  ->  GPIO18      - header pin 12                  *
#*    GND  ->  GND         - header pin 6                   *

import pigpio

GPIO=18

pi = pigpio.pi()

if pi.connected:
   print("Connected to pigpio daemon !\n")

dm = 0
while dm < 860:
    dm = input("Enter Dimmer Value: ")
    dm = int(dm)
    pi.hardware_PWM(GPIO, 5000, dm*1000) # 5000Hz dm*1000% dutycycle

print("\nOut of range. Exiting...")
pi.hardware_PWM(GPIO, 5000, 860000) # 5000Hz 95% dutycycle
pi.stop()

save it as “test.py” in the PIGPIO folder generated after the full install is done.
