@scalz are you going to sell this on openhardware.io as a complete module?

[scalz]

@kenci I think so...this is a very nice new feature on openhardware, not only for commission (sure that could help a little bit for dev cost..) but, more interesting is to have competitive price for some device and make these available for others, that's excellent :) I can't wait to test this, to see what will be the quotation..I will try to do my best ;)

Hi @scalz great work i am working a project like yours but i do not understand teh principle of MDC3105. The shematic i made like yours is below, search a little but don't find anything about it. Is it correct without any resistor, diode etc.?

The normal schematic is below with diode, resistor, transistor etc.

Thanks for share it.

@ddos Yes, that would work - if VIN1 is pin 5, VOUT1 is pin 6, VIN2 is pin 2 and VOUT2 is pin 3, that is.

It's a bad habbit to have "double pins" in the schematic. You should really make a pin for each ground connection - just my 2 bits.

@jbjalling thanks for your quick reply. If this is gonna works without any additional parts my board has more space. I copy the device @scalz schematic i am going to do new library with two GND for it thanks again.

@ddos
jballing is right. the relay driver already handle this. it's integrated, less footprint. be careful playing with AC, you need to know what you do ;)

btw I am a bit cheap on pics and late I know :blush: a bit busy too but few pics of what it looks..

45x44mm seems to fit ok. millings for additional distance etc...

@ddos, Hi Srs., at first moment.. thank you very match to share this project, I like to try this project in my home but I don't know where are the library/code to try to use in my system., someone know where I can found it? :wink:

Thank you.
Antoni.

@anarro sparkfun libraries is good you can find them on github and of course adafruit library. If the device you are looking for is not in the libraries you can find them on google 80% chance. If you can not find them on net you should do your own devices.

@scalz your pcb and cutouts look very good for voltage protection but i think you need a case for 230V AC pins which are touchable right now.

[scalz]

@ddos
thx. of course! i will print an insulating box with some air vents. and i will add some liquid tape for isloating the pads ;)

for software, i need some time to clean and test it. and i am playing with others things+ etc.. I already shared the sketch with only one beta tester here, for the moment. but of course i will share it asap :)

Made my first test tonight. Only a proof of concept with the first board and without auto-calibration. Yes I know, I have only blue wire near me ...

[anarro]

@scalz Hi, I know that you work (I readed your another posts) with code to use with this board, with sensor current and auto calibrate options... so if you need..I can help you.. or I can try it...(-;

Thank you.

[scalz]

@Fabien great :+1: .did you try the sketch too? I will improve it a bit ;)
@anarro : thx. I will install one board at the end of the week and will try to make a small video of the thing actuated by another cool thing I am finishing :)

[anarro]

@scalz ok, I m waiting you news... good news!! :wink:

[ddos]

@Fabien Great demo with blue wire :)
It seems the board will not fit in the wall case behind the switch because of the height, did you try to fit it?

[anarro]

@scalz
Hi, can you install and test the board?, do you have a some news??

[Fabien]

Personnaly I wait for EEPROM (the one I solder are not compatible). And I will try autocalibration.
And I will make PCB with the last version when release (smaller) and a plastic case (3D print) ... Lot of work !

[gonzalonal]

What happened with this project? Has been abandoned or finished successfully?
Have you tried automatic calibration?

[scalz]

Yes this is a finished project on my side.

@scalz Does the NOD works with domoticz? Is it possible to communicate with rs485?
