Roller Shutter

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.

@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.
You can get more informations about this project here https://www.openhardware.io/view/22/Roller-Shutter-Node

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

Guillermo Schimmel

Hi! Is this thread alive? I found this and it's a great piece of soft+hw. Immediately aborted my attempt and adopted this one.

It has however some space for imrovements. So far I have identified two issues that I needed to correct:

Report current position of the rollershutter. It's needed by my controller (openhab via mqtt) in order to show the real position of the shutters. It's working.
The openhab controller also happens to have reversed the 0-100 percent concept of closed/opened, so I reversed that in software.

Are you interested in having some pull request with these modifications? I'm glad to do that.

Thanks a lot for your effort.

Regards

Hi @Guillermo-Schimmel , right now I'm just trying to do what you did. I'm interested in building a home automation system based on openhab and a raspberry pi from scratch, which reliably controls the roller shutters at home. I have already built one in the past, very basic, which using some relays turns on and off the lights and allow to simulate the pressure of the buttons at home raising and lowering the blinds. However it lacks to indicate their real position, and moreover, by pressing physical buttons at home, their new state (fully up or down) can not be communicated to openhab, so I can't know if they are really up or down. So I decided to start from scratch building also a new control unit for the shutters. The hardware of this project is extremely interesting, but I can not figure out how to interface it with openhab.
My idea would therefore be to build two control units, a primary - which I will use for the lights and other sensors, very similar to the one I already built and use - and a second one dedicated to the shutters, based on this project but with the possibility to manage five shutters and connected to the first with serial or rs485 (they would be very close, so I would avoid the radio section with attached authentication). Can you help me, giving me information about the connection between this project and openhab, so I can succeed in this little adventure?
