Hi, I can't find a solution to my problem.
I'd like to change the name in a function in a for loop. If it is possible?

for (i=1; i<5; i++){
int value[i] = debouncer[i].read();
}

Thank you for your help. It was enough to add the if condition depending on the message.sensor.

Hello, I've got Raspberry PI with Domoticz, and Arduino Mega 2560 as Gateway USB.
I want to two dimmer controling on Domoticz, and two switches (on/off) controlling on Domoticz and manual switch. My sketch don't work coretly. Switches (unit 1, 2) controlling also dimmer (unit 0). Please help why this is happening?
