      By splitting one line, so for the intercom the black cable to the module, then a cable from the module to the connector where the black cable was connected.

      Same for the lamp.

      Can't seem to get a good readout from the module yet.

      Tried the following code

      /*
      Measuring Current Using ACS712
      */
      const int analogIn = A0;
      int mVperAmp = 185; // use 100 for 20A Module and 66 for 30A Module
      int RawValue= 0;
      int ACSoffset = 2500; 
      double Voltage = 0;
      double Amps = 0;
      
      void setup(){ 
       Serial.begin(9600);
      }
      
      void loop(){
       
       RawValue = analogRead(analogIn);
       Voltage = (RawValue / 1023.0) * 5000; // Gets you mV
       Amps = ((Voltage - ACSoffset) / mVperAmp);
       
       
       Serial.print("Raw Value = " ); // shows pre-scaled value 
       Serial.print(RawValue); 
       Serial.print("\t mV = "); // shows the voltage measured 
       Serial.print(Voltage,3); // the '3' after voltage allows you to display 3 digits after decimal point
       Serial.print("\t Amps = "); // shows the voltage measured 
       Serial.println(Amps,3); // the '3' after voltage allows you to display 3 digits after decimal point
       delay(2500); 
       
      }```
      
      

      It gives me the following readout, tried the multi meter on signal and also a lamp on ac. It shows these values even if nothing is connected. Connected the module to pin 0 on the arduino and provided it with 5v from the arduino.

      Raw Value = 876 mV = 4281.525 Amps = 9.630
      Raw Value = 877 mV = 4286.413 Amps = 9.656
      Raw Value = 878 mV = 4291.300 Amps = 9.683
      Raw Value = 877 mV = 4286.413 Amps = 9.656
      Raw Value = 877 mV = 4286.413 Amps = 9.656
      Raw Value = 875 mV = 4276.637 Amps = 9.603

      What would be the formula to just show Voltage?, when the door is ringed the voltage changes from 20v to 23~24v, when the button is pressed to open the door it drops to 17v.

      The ACS712 should arive today, however I couldn't find the sketch to send over the voltage measurements, maybe I'm overlooking but which sketch can I use?

      Could I also use a ACS712 30A Module to see if there is a change in voltage with a script in domoticz?

      Hi Sparkman,

      Used the multimeter and it gives a reading of 20v dc. when the button for the door is pushed two metal parts touch each other and will send a signal to open the door.

      Soldered 2 wires to those connections and it seems to work with the relay, the only thing I need to figure out now is how to get a signal when someone rings.

      Yes, this is the inside box in my appartment, I think the green wire is for opening the door. When I get home I will try to solder a wire to the button and use a relay. That sould work I think, then I need to create a blocky in domoticz that when I push the virtual button inside domoticz it turns the relay off again.

      There is indeed no separate power line, I have a multimeter, could you help me which setting I need to "detect" a signal on one of the cables when I push the button?

      Hello,

      I don't know if this is the right place to ask for help for my project.

      I live in an apartment building, so I have an intercom to open the door downstairs if someone rings my doorbell. I want to use mysensors to get a notification via domoticz on my phone trough pushover, and be able to open the door via domoticz.

      I just started with mysensors, and I'm also new to the electrical stuff so hopefully I will learn how to this kind of stuff.

      My intercom is a SSS Siedle, it has 2 wires going in a black one and a green one. one is probably for opening the door and the other for the voice.

      I would really appreciate some help how to wire this up to an arduino, but still be able to use the horn and button on the intercom itself.
