@TimO Would you mind showing a sketch of your setup, and the used components?

The thing I don't understand is how you simulate the button push ...
It looks like you use a relay, but is a relay not always on or off? so sending a 24V pulse to the DIN Relay only requires the relay to switch on for 1 sec.

is that what you are doing here?

     // Change relay state
     // WE ONLY EXPECT a 1 == on HERE
     digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);
     gw.wait(1000);
     digitalWrite(message.sensor-1+RELAY_1, RELAY_OFF);

@AWI I think you are right looking that the size to accomplish my goal, the sensor in wall scenario is going to be to big.

Hi all,

I'm looking for a solution to simulate the push of a button to control my lights.
Right now i have wall push buttons installed to control my lights. These buttons close a low voltage 24VAC circuit to operate a DIN mounted relay on my electrical control board to switch my lights.

Is it possible to build an Arduino sensor that (preferably) fits inside my wall switch, and can simulate a pushbutton that closes the 24VAC circuit for a second to act like someone is pushing a button? I would like this to work parallel with the current setup, so it can sense manual buttons pushes as well and report this to my controller.
If not possible to build it very small it would also be possible to mount it at the electrical board.

Any help or tips would be awesome!

Still no update? I would love to see the hardware setup

@twosh any update on your project?
I have exact the same setup, would love to see your code

Hi,

I was looking at the Relay code and noticed that there is no support for multiple relays in the RelayWithButtonActuator code. How can I change this code so I can use a 4 Relay board?
Any help is much appreciated!

Hi ferpando,

I'm also very interested in your project ... so if you can share your full setup that would be very cool. And keep up the good work.

BWT. your sketch looks very advanced, this is not your first time ... right
