Yes i know, like i said in the first line for 1 or 2 its nice but when you need more its not a great way to do it.
or the pcb's are very small.

If you are doing only 1 pcb or 2 it is oke to use a cnc milling machine,
i needed a bunch of boards for my home automation project and it took way to long.
Changing bits for engraving/drilling etc and then the costs of the pcb itself.

I went to https://www.itead.cc/open-pcb/pcb-prototyping.html , double sided smaller circuits then with your milling machine and coating , looks like factory pcbs.

it is fun to see the machine working though, made some timelapse videos.
click for the video

This looks very nice. Love the led to see what's still on

Thanks Awi for the reply, i just noticed it and actually forgot to look.
This is great news , i will start collecting some parts i need and a few Arduinos to make it hopefully work.
Will report how it goes !

This is great , exactly what i was looking for.
I do have a few questions, is it possible to double the amount of inputs ?
I "need" 24 or 25 inputs since i got so many meters like on the picture.
Or is it possible to build 2 of these devices and that domoticz detect it ?

Also, can you maybe tell me if it is possible to keep a log from all the sensors apart from each other ?
So you can check what meter 1 has used for the amount of days/weeks/years ?
Or it it all combined to 1 number ?
