Hey @drvkatwijik. I assemble this but what its Input voltage? Right now in my PCB it already connected to 24v. But can you share its specifications? What its input voltage? and any tutorial available on this?

@projects_7336 Hello,

I use 12 V input but 24 V should be OK.
I have no tutorial for this.

I use this to control lights and monitor switches. I use the ESP module just to replicate inputs and outputs to my home automation system (Jeedom) witch connect via Wifi to it.
One wire input is used for temp sensors, I have put 10 in parallelle on it using a simple connexion board.

If I may help you for anything ask me.

Kind regards
