@Boots33 Thanks they are working now!!!!!!!
Unfortunately i dont know about coding, i am more of a hardware guy, so i will just have to live with that.Hoping that in the future someone will write something and share it with us.
Thank you once more.

@hek the think is that the switch works using Domoticz, but when i use the pins for the hardware switch , i get the icons updated in domotics to on or off but my lights stay off

Anyone has the hardware switches working??? I can't make them work!!!! Help please!!!!!

Hi everyone.Its me again!!!!
Everything seems to be working just fine when i am using domoticz interface, but when i am using the hardware switches the icons in domoticz update from off to on but my lights wont turn on. If i turn my hardware switch to off, the state in domoticz stays to on.What am i doing wrong????
My sketch below .

 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 * DESCRIPTION
 *
 * Script for double SSR relay board by Aproxx
 * https://www.openhardware.io/view/77/AC-DC-double-solid-state-relay-module
 * https://forum.mysensors.org/topic/3671/ac-dc-double-solid-state-relay-module
 * Control 2 circuits either from controller or from physical buttons connected on pins 4 & 7
 * Optional DS18b20 is connected on pin 8
 * 
 *  HISTORY :
 * xx/xx/2016 original version by Aproxx
 * 08/02/2016 upgraded to MySensors 2.0 by mr_const
 * 08/30/2016 changes by Nca78 :
 *        - fixed initialization of physical buttons/debouncer status
 *        - centralized pin status change for relays in setRelayState method
 *        - centralized debug information for state changes in one method + added debug info when changed by physical switches
 *        - added #ifdef MY_DEBUG before each Serial.print (saves prog memory when not in debug mode) and F() macros for debug strings (saves RAM when in debug mode)
 *        - added #define USE_TEMP_SENSOR to make temperature sensor optional (not used if line is commented)
 *        - put back #define for repeater feature
 *        - add #define TEMPERATURE_ROUNDING for custom temperature rounding

@stray the think is that the first relay is working normal and i see the updates in domoticz when i turn it on or off.It is just the second relay that gives me power either it is on or off in domoticz.That is why i am thinking maybe the second relay is broken

Either pressing on or off in domoticz, i have always power on the second outpout.

I solved my last problem, but now i see that although both of the switches in Domoticz show off, i have power on the second one. What could be the problem? Faulty ssr?

Hi everyone . I managed to create my first module and it seems to working but why at my domoticz only one switch appears as new device???

Never mind, got them. thank you!!!
