💬 Roller Shutter Node

[Nca78]

@scalz I agree with you it's not the best choice, I just want to try it anyway and see how it behaves. The configuration you use is probably the one used in commercial products, but my neighbour has some electric shutters with fibaro modules and they are really tiny, I wonder what relays they use. They have an external antenna (a wire) so it probably eases the internal design, they use a transformerles design, but I still don't get how they can fit relays inside and respect clearance/creepage.

I'm tempted with your board, but like many others the SMD components are putting me off at the moment. Wonder if this type of board would not be a good candidate for an ESP8266 module ?
It would take space similar to a radio module, but without any routing needed to connect to atmega. (and the castellated pins are not very hard to solder :))

This post is deleted!

[scalz]

@Nca78 oki it's good to experiment by yourself you're right and if you do something better, sure i would use it I'm not dumb!

for esp8266, i thought about it too.
First, I'm not a fan of wifi for rollershutter, it's like a door..I prefer something more secured with atmel/rfm/signing. But i have tried in eagle to see.
footprint was not really better! just looking at the topview, it's difficult to make smaller..as you can see with @dpressle board, which is nice design though, but 5x5, not same features, and i don't know about thickness, antenna near traces etc..so not same goals as I said.

for fibaro modules, I don't have one so i can't tell, I know they are good in miniaturization. but I'm pretty sure they are using transformless, with a very tight, controlled and professional design etc..but my design is opensource work (almost for the moment) with a current sensor which can add some versatility who knows.

Maybe not so easy to handsolder for noobs, i can agree.
I could have used 0603, instead i kept 0805. in case middle experienced people would build it with moderate tools. even a noob who want to learn and know a bit about AC. On my side, no glasses and i don't need a magnifier with 0805, nor 0603 but it's easier with one. Maybe lucky. Try maybe you don't need it too guys, with little patience, pratice and fun I admit I'm not noob but I'm not former electronician.

A trick: if not really friendly with smd, and need some boards, a stencil costs 15-20$, it's reusable, boost the job, and if you don't have reflow oven, there are multiple alternative like using your solder iron as solder paste is already applied, or hot gun etc.

taste and colours sometimes...

[Samuel235]

@scalz - Where do you get your stencils from, everywhere that i have asked they are $60+

[scalz]

@Samuel235 Elecrow when i order pcb, or oshstencils.com is great too

[m26872]

Beautiful design @scalz ! (I've looked before, but closer this time.) Compact, neat, safe and many features. Another AC design reference to get some ideas and inspiration from.

[Samuel235]

@scalz - Thank you! Finally an affordable stencil provider.

[scalz]

Hey guys

this time is time for update
rfm69 version is uploaded. Added a bit of documentation. github in sync with this topic. gerbers and design files released too.
Only STL and the sketch are missing, not for long, I have just finished to write and try formatting my post, upload and check everything etc.. Maybe there are some typos in doc I think etc..

I am looking if it could be interesting to use PCBA through pcbway or others.
At least, pcb should be available here through pcbway, I have pushed the button

Enjoy

[Nca78]

Great, I would be interested in PCBA board as I'm not feeling motivated for playing with solder paste and buying a reflow oven yet
I'm more interested in a NRF24 version and if you can only get RFM69 version with PCBA then I will adapt, but maybe you can have an option without the radio ?
At the moment I would order only 1-2 boards to make some intensive testing first, I have some big windows (over 2m*2m so it will need a relatively powerfull motor), and tropical weather with high temperature and high humidity.
But if it survives the local conditions I have 9 manual roller shutters in my appartment and I know some neighbours are interested in home automation stuff also, with 350 appartments in my building there's some potential for orders

[scalz]

@Nca78
wow! cool.
I hope it will fit your needs

For the nrf24 version, I just need to add few silkscreen, and it's ok to upload, it's the same version, only rerouted a bit differently at radio side.

don't worry no need of a reflow oven, just a fine solder iron. but I agree, sometimes because I feel something easy I think it's easy for other..
That's why I will ask pcbway for the PCBA and I will ask my regular fabhouse too.
I am thinking :

• only pcb
• only smd parts soldered, up to us to source others component like relays, radio etc..
• full assembled. curious to see the cost.

On my side, I can do very small batch sometimes. like 10-20 boards. But I live in France, so, for far country it may be not interesting regarding shipping fees etc

I'm also actually working on release for others boards..I need to sort all my stuff, to have more air for software and new hardware..

[Nca78]

@scalz in fact je suis Français
Do you think you can have one board ready in around a month time ? I'll have family coming from France at the end of september so I can give you an address in France where to send the board

I'm pretty sure I'll be ok with smd after some time, but I'm just not ready yet. I have bought some kits to train before I try before I do it on real boards/components.

[scalz]

@Nca78 hehe. that's what I thought first time i saw your nick, don't tell me why maybe the 78 that's fun.

I will see. this is nrf24 board you want, isn't it? I have no of these in stock but I have an order of multiple pcb to do this week. so I will buy a set. I will use DHL..not so patient when there are new boards to try So I will tell you what I can do..

[Nca78]

@scalz If you are not ready with the NRF24 version I will be fine with a RFM version, I'll just build a RFM gateway it's not a big deal, and I'll have no excuse not to try all those nice boards with RFM69 that are on openhardware

[scalz]

nrf24 smd version is uploaded. Have fun

[fets]

@scalz I'm another one from France and very interessing in pcba version with rfm69 cause sma is not my cut of tea :).
Anyway thank for your work and ideas,

[scalz]

@fets cool. About PCBA, for the moment; it's on fabhouse hand, I'm waiting for the quotation, and if everything goes well, this board may become a part of Mysensors project, meaning supporting Mysensors, I'm very glad

[coxifred]

@Scalz : Hello, what a great job ! it's exactly the thing i'm trying to do since few months. But severe issues with relay and my 220v rolling shutters. Actually, the relays freeze sometimes and stay glue to a position. I read a lot about the inductive load and snubber, but i'm a newbie with electronics. I tried differents relays : from blue one classic to APF30205, but always fails.
Did you encounter problem with your OMRON G5Q ? Is the varistor the solution or it's only for other purpose (security,...). Here is my project https://github.com/coxifred/PimpMyCeliane/wiki
Thanks for you response, and congratulations (twice).

[scalz]

@coxifred
Hello. sorry for delay..busy time..
I already did my design when I saw your build. But I preferred to not use wifi for rollershutter..

If you're newbie in electronics, be careful with AC and your motors

• I don't see any safety on your build..
• seems your relays are in //, so not interlocked. Better in serie, so you can't do UP & DOWN at same time. Not a problem in software, but if parasitic problems, then it could happen.

I have no problem with my relays but I have only tried on a somfy motor, and another old blind motor.

Relay can stay glued because of multiple reasons, not easy to debug at distance

• EMI parasites etc... esp8266, especially nodemcu module could be sensitive. And lot of wire etc near AC lines etc is a nasty combo. this would not pass EMI tests!
• So, at relay input : EMI for instance or, I don't know if your relay module has this, but that's better to use relay driver or at least some diode. . It can avoid improves false things on relay input.
• If you're sure you have no problem on relay driver/transistor side, then it can be at output. It can be stayed glue in inductive overload for instance. If bad quality relay. If relay is good quality. Perhaps you need an additional snubber. Which is why I have oversized my relays (10Amp).

Maybe I have missed few others points, but I hope that will help you

[coxifred]

@scalz : Thanks for your response. For me all eletronic/software before output is ok. I tried with simple bulbs, works every time, no glue. The problem appears only with rolling shutter motors (wich are not somfy, but 220v). I think i need a snubber (for inductive overload ) but don't know how to wire it at the output, and wich model. I'll buy your relay model and test again. Perhaps i was not lucky with my relay. I even buyed a Chacon/DIO (433) rolling shutter module to see what kind of relay are they using. I have to take a voltage measure on the (chacon) input's relay, not node, too much time:)
Thanks 4 your response.

[tonnerre33]

Hello,

The PCB order link is for nrf24 or RFM69 version ?

Edit :

omg, i see the answer in the first page ^^ it's for RFM69 version .

When will you give the link for order PCB with nrf 24 ?

[tonnerre33]

Hello,

Where can we found the program (.ino) for this board ?

Thx

[Takero]

Where can i find the example sketch?

[Fabien]

There is no official sketch avaiable at this moment. And @scalz is working hard on RFM69 ... I began yesterday to write a new sketch, I will publish in few days (weeks ?).

[scalz]

Why do you want an example sketch ?
hmm..my precious sketch
@Fabien is right that's quite busy days
I didn't published it yet because i prefer release when it's polished as i like..
Well, as Fabien is a betatester
i've published a pre beta version! on my git https://github.com/scalz/MySensors-HW/tree/development/RollerShutterNode/FW/MyRollershutter

BUT i'm actually busy so i won't have time for support on setup. i think it's enough documented for the moment.
I prefer to tell this than giving hope..better like this. I learnt this from a smart guy recently

That said i hope you will have fun! and i will try to update as i can..you've not seen the new version of this board

[Takero]

Hey, no Problem

I just ask for it, as you write it is in the examples folder

Thanks for the pre Beta, i will work on it

[tonnerre33]

@scalz Thanks for the pre beta sketch.
i have searched the sketch many times in the example folder too But no examples folder find
I have posted some pictures of the pcb here i fyou want to see:

http://www.photorapide.com/albums/jordan/khjept/circuit-pcb-roller-shutter-node.html

[Takero]

Hey Scalz, u have forgotten to connect the CSN - Pin in your PCB file for NRF24 I just solder a bridge between NRF Pin 4 and R14

[scalz]

@takero
thx for reporting!
i'm using rfm69, argh. i will take a look asap.

[Takero]

Yah, i know, take it easy this is an minor bug
Your misstake is in the schematic, your wire on the NRF24 CSN-PIN is unnamed.

For feature Update, it is advisable to plug an ELKO ~400-500uF near the NRF24 Power, i have reciving problems whith "RF24_PA_HIGH" but i need hight for the distance.

[scalz]

@Takero

But it was named! or the pullup resistor would not be wired, and it was also present on atmel.. and no airwire, weird!
well, i think it happened during converstion to nrf24.
Hopefully the pullup resistor is just near the radio!

Is RF24_PA_HIGH available for nrf24 smd, i thought this was for High power nrf. i'm certainly wrong..I've no problem with rfm though.

I don't think i will do more, unfortunately, I mean in this case, it's sort of double job, and i'm using rfm69.
but when i can, i put rfm69 and nrf footprint (i have a pcb not released like this, not a shutter node).

Now it's updated rev=1.3a for nrf
See you soon

[Takero]

One question: what are your fuses settings for Optiboot? Dit u use the external 8MHz Clock?
Can you confirm:

L: 0xEE
H: 0xDA
E: 0x06

[Takero]

@scalz Yes, the resistor is very close

In my .sch the wire is not named But anyway it works

[scalz]

@Takero

What the ??
Are you using Eagle 7x ?? I'm still using 6.5..when it works i don't change if no need
but dooo! In my version i see the signal..i think this is sort of very exotic bug case and i got in my face lol

Weird, hein !
no matter thx for reporting, good to know i'll remember or update, we learn from our errors as we say

[Takero]

@scalz
Yes 7.5. Hey it was an "easy to solve" problem

. . . maybe an eagle bug

[scalz]

easy to solve when you've eagle 7.5 ahah

For fuse&bootloader, you can use OTA howto, that's the same : https://www.mysensors.org/about/ota

[Takero]

@scalz Are you sure about the Fuses? 0xE2 is normal for int. clock?! Or i am wrong?

http://eleccelerator.com/fusecalc/fusecalc.php?chip=atmega328p&LOW=E2&HIGH=DA&EXTENDED=06&LOCKBIT=FF

[scalz]

yes this ok, i'm using this for most of my nodes.
And your link shows that it sets internal rc.

[Takero]

Ok, Thanks

[Takero]

Hey Scalz,

my prototype of your RollerShutter works well right now. I have add an Capacitor (470uF) near the NRF (it is realy needed! otherwise OTA CRC Fail, lost packages)

I have a litte bit trouble with the Current Sensor or the calculation of this.
I Used 2 60W Bulbs, if i PressDown or UP the Power Value increase up to 350W and need a loooooooonng time to decrease. round about 1W per sec.

Is this normal? In my opinion not but maybe my ASC is defective? I use a modification of your pre-alpha Sketch

[scalz]

hmm. i didn't have 1w/sec.. perhaps acs.. i've already got a few defective. i'll check a bit when i'll have more time, too much cooking.
In case you can set default define duration, and this works well then.
But looks you got it! Great to hear it though

[Takero]

Yaah dont hurry

[Takero]

It is possible that you dont use the asc for the autocalibration yet? I cant find it in your Code .... I found only the read process.

Corect me if i am wrong.

[scalz]

acs read can set an endstop bool = "event" which trig the shutter state machine. you should see it
in case you have some trouble, then you can set few default define in sketch to set your travel time. perhaps a cleareeprom needed, then shutter should be ready.

[Takero]

@scalz

Yes, i work on it . . . still my ACS wont work well. At the moment i init the node with the Endstop Bool, that works fine.

I work also on an delay between the UP/DOWN States, i don't like it if the shutter change the direktion directly. But . . . not find the right way yet

EDIT: ACS works right now!!! I think my IC was defective

[Takero]

Dont know why but while autocali. they stop messurement of current . . .

If i start the process the first is go UP, my messurment of power is: 30W
if i Power of the attached Bulb the value stays on 30W, so it is normal he cant detect anythink

In your loop:

 // Read current sensor, endstop
  uint16_t acsread = 0;  
  acsread = readAdcWithFilter(ACS712_SENSOR, PS_64); 
  if (acsread < ACS712_LEVELDETECT) {
      // Endstop detected  
      if (getCalibrationState() > 0) setEndStopState(true); 
      else {};
  }

I modified for debug like this:

// Read current sensor, endstop
  uint16_t acsread = 0;  
  acsread = readAdcWithFilter(ACS712_SENSOR, PS_64); 


  Serial.print(F("ACS712: READ DEBUG: ")); 
  Serial.println(acsread);


  if (acsread < ACS712_LEVELDETECT) {
      // Endstop detected  
      if (getCalibrationState() > 0) setEndStopState(true); 
      else {};
  }

It never change the value of acsread after the init process is started. . .

[Takero]

I am finished and everythink is working well right now.

I dit some modifications on PCB:

• add an 470uF near to NRF24
• add two Diodes recovery diode (or free-wheeling diode) dunno how it called in english at the relays

And some changes in your example code

Thanks for the Layout, thanks for the code, thanks for help!

I design a 3D Case, but only the bottom side. . . but not tested right now . .

[Fabien]

Did you try ACS measurement for up AND down ? On my 2 boards, i have problem with relay just over ACS and errors in current measurment (magnetic field of relay just over Hall sensor)
@scalz : I think we could try to turn 90° acs712, it could be fine.

[Takero]

With a Little Bit Trouble yes. The Problem is the Dimension of the amplifier. Below 60W the messured voltage is to Low.

I think it is netter the Diode must be in the Feedback cycle of the amplifier. But in my case the Free running voltage is below 6 and with running Roller above 20. So it is possible to detect the End stops. Just modify the variables.

I will Test it in the"real" System tomorow. If it Works i will post the Sketch.

[scalz]

@Fabien
i will take a look asap.. i'm actually playing with my nano32, and some design
perhaps for the atsam version when more time to release..

@Takero
thx for feedback

• i'll look to your suggestions too. for the wheeling diode if i remember it's integrated in the relay driver. depends what you mean.
• For sketch, hehe, i warned it was not complete but the most important there. I'll look at your change and update it, sure !i have actually no time to play with it, still using an old sketch.

too much coding to do, and hardware to play! but this is so fun

see you soon

[Takero]

@scalz said:

It isn't

[scalz]

well, it is a zener, not wheeling diode, which should be enough..
http://www.onsemi.com/pub_link/Collateral/MDC3105-D.PDF
perhaps not for nrf! cool if it improves.

sidenote: i won't change nrf version in future. as i only have rfm69 (doing nrf was bonus), i don't want to waste my time improving both! and i have enough pcb ahah

[Takero]

Dont Care its cool. Zenner its not enoth but dont worry. I need it .. the nrf is verry "female" (sensible). But i think for both version, you have to modify the current messurment. No Roller shutter has >200w so u are on the Limit below 100w of adc scale.

But hey it Works and your Layout is verry cool and Safe.

[Fabien]

Very stange. Zener in forward side is equivalent to classical diode.
@Takero, you change the amplifier ? Wich mods did you make ?

[Takero]

I was a little bit bussy the last days.
My Nodes are completed installed right now, it works well. BUT, i had to change some thinks.

I had the Probleme of automatic reset of the device if i set the shutter to 50% or anythink else 0% or 100%.
The Diode alone dont solve these Probleme. I think the Problem is to stop the shutter while running. If i set it to 100% or 0% the shutter shut of before the relay falls down.

I solve the Problem with a 220uF Capacitor at the 3.3V Out and deactivate the BOD.

My Fuses right now: L: CF // H:DA // E:07

Now it works very well!!

@Fabien: I dont change the amp . . i just tested some thinks but it wont work . . for i dont use the current messurment and setup the Node with the manual endstop. It works realy good!

Finaly again, Thanks @scalz

The Temp. of the devices is below 30°C

In the picture the green temp.

[fabiancrg]

Hi
I was wondering if the ACS712 can detect the current if the roller shutter power is 85W?

[kduino]

Hi, there is something similar available although without an ac712. So you can't check the percentage o the shutter.
See https://github.com/JanGoe/esp8266-wifi-relay
I had one at home and it is working well. Because of the esp8266 it is directly connected to any controller using udp or MQTT or other protocols.
The only problem is the missing box. I have to admit I wouldn't put this in my wall without a proper box using AC 240 V!!!
The project you proposed is of course the most advanced. Do you think there is a smaller version available perhaps less parts on the BOM and easy to build?
Thank you very much, kduino

[Fabien]

Cloudy/rainning day ... Good for MySensors

[Fabien]

There is a mistake on the above photo. Radios are on the wrong way (180°)

[Fabien]

@scalz, little mistake on BOM, C4 is 100n AND 10n ..

[Sergio Rodrigues]

Hi, I make this project, pretty cool.

How I can upload the firmware? What I need to do?

[scalz]

@Sergio-Rodrigues
It's better to talk about this here instead of private, so other people can learn or help you

it's "like" programming an arduino board.

1. in arduino ide, program bootloader (for these, i used the sensebender board in Board manager).
2. Then, with a FTDI adapter, program the rollershutter sketch.

For more infos on programming arduino:

• see official docs from arduino website
• https://www.mysensors.org/about/fota for a bootloader programming example

What do you need to know exactly ??

[Fabien]

Finnaly I find a solution with a very good WAF !
I want to keep a sort of manual command (not gateway or controller dependant) and I don't want an expensive solution (my ODACE schneider button are quite expensive and I don't want to buy other button).
But these button measure 38mm depth and @scalz board is about 20mm. My wall boxes are 50mm !
Si I find some special wall boxes with an enclosure for home automation module. It's cheap (about 3€) and very well designed (french RT2012 compliant). I update the sketch with MY_TRANSPORT_WAIT_READY_MS so node can work alone. And I update sketch to work with bistable button. Works well on 2 windows since yesterday.
Here is a photo before :

[hek]

Almost looks like this type type of part-rubber box that can be mounted without tearing down the wall:

Some other photos (sorry, first one is not in the same room) :

[Fabien]

One test screenshot (not definitive) of my habpanel (openHab 2.0 part).
I'm using OpenHAB mysensors binding (from @TimO), node-red for rules, habpanel for UI, Tasker on android (for example open all RollerShuter just after morning alarm !).
I can access OpenHAB via nginx reverse proxy with https and on my LAN, home automation have a separate VLAN (for security reasons). Thanks a lot to @scalz for this module.

[Soloam]

@scalz great work, sorry to dig up the topic, but good topics never die ( ). Can you clarify some questions?

• Way did you used 2 different relays? Way not only one type?
• What is the Amp consumption of your motors? I know that 10A is overkill, but just to get one idea. Would 2A do it? (at 220V)
• I see that you added a 8Mhz Cristal, way not use the internal clock? It's 8Mhz
• I see that you use a relay driver, correct me if I'm wrong, that is because the rated coil consumption to those relays is 80mA.

Thank You
Great Work

[Fabien]

@Soloam
2 relay for interlocking system and add more security.
I never mesure my current but it's low ... not 10A !
Internal clock is not very precise and can vary with external parameters like temperature. And for this project it's better to have good precision.
It's always better to use relay driver and not directly arduino pin.

Thank you @Fabien all very clarifying, only one thing that I don't understand (sorry, but I like to use this projects to learn and improve my personal knowledge) I still don't understand way the relays are different model numbers, from what I can see, one is 4 pins, and the other 5 pins, or I'm miss interpreting?

Thank you

[gohan]

one relay only needs to be on/off while the other needs to select between up and down motion.

[scalz]

@Soloam
about relays, imagine there would be two same relays:

• two SPDT would not make sense here, plus it would add more pins.

• two SPST wouldn't be secure, there could be a moment where you could have both relays activated (for example in case pins are not well set on startup, or of bad sketch). That would not be great for motor.
  So there is one (SPST) to enable power flowing to the SPDT which toggle between UP or DOWN.

• there are parts on my schematic which could be optional. I always put as much footprints as I can, for reference, and especially when I need to fix something it's handy.
  Sure crystal could be optional, and you could burn sensebender bootloader for example, or like fabien said it's good to have. It's an AC powered node, so not really needed to try saving something. And also, if you're paranoid about sourcing cheap, and why not out of specs, atmel on aliexpress, then you have the footprints available.

• the relay driver is nice because it helps protecting atmel and improve reliability. It integrates all parts for relays in one package (transistors, diodes, resistors etc.) so it simplifies schematic and takes less place on pcb too.

• 10amp omron relays, better oversize, so you're sure they won't suffer and the board can be used for other stuff needing more power than rollershutters in case.

[Soloam]

@scalz this is a great work, I'm planning on ordering a couple to use on my system.

Besides that, I'm most interested in the integrated Current Sensor, and planning on use it on my one PCB. I've been studding your PCB layout and reading regarding the ACS712 and is integration with the LM321. Way didn't you use the schematic on the ACS712 DataSheet (http://henrysbench.capnfatz.com/henrys-bench/arduino-current-measurements/acs712-current-sensor-user-manual/ page 12) to integrate with the LM321? I see that you use a lot more resistors and caps, and the values are not the same. Was this intencional or you did it to reuse a footprint? Would the layout on the DataSheet also work in you board? (From what I can tell it changes the sensitivity).

Also I see a couple 0 Ohm resistor, I think that that is to reuse footprints correct?

Thank you for your help and contribute to the community.

[scalz]

@Soloam
Your link is about DC. He has another howto for AC, which is based on sampling adc but i was not interested in this one. I didn't want the current measurement dependant on sampling reliability and misses.
So I used part of datasheet schematic, and I adjusted it to my application. If you use it in another projects, you may need to adjust resistor divider etc.
0ohms needs to be soldered.

[hitech2207]

Hi,

I have been searching for a longtime for some decent rollershutter solution. I have about 12 of them and i am currently using a sonoff relay solution which works but i never really know the position if it is open or closed or pourcentage position.

What your solution seems to do.

Is it possible to interface this with amazon echo or google home to ask to open/close the shutter but also ask the status. Are my shutters open or closed? Or open window shutter 1 at 50%?

Also there is a link to purchase 10 pcb at 21$ is the the complete solution (plug &play, including relays, connectors,,,) or is it just the board and do i need to solder everything my self?

Thank you and great job at doing this!

[gohan]

You still need to get parts and solder everything together.

[hitech2207]

Hi,

Where could i buy a finished version of this hardware?

[alexsh1]

@hitech2207 I do not think it is for sale as a finished product.
You still have to get everything assembled as @gohan had.

EDIT: re amazon echo or any other control can be done from RPi hosting a controller.

Hello, nice Node! How to order a NRF Version? If i click buy, i have no choice.

I'm having difficult finding the IC4 ACS712_5A, if I search for "ACS712 5A" I only get the assembled unit. Can I get one of this and unsolder the IC and use it?

you can unsolder, I have repeatedly had to do so))

by the way will share subtlety, in order to get good data from the sensor signal to untie from MCU. Then you forget about noise, electromagnetic interference and so on...

@soloam said in Roller Shutter Node:

I'm having difficult finding the IC4 ACS712_5A, if I search for "ACS712 5A" I only get the assembled unit. Can I get one of this and unsolder the IC and use it?

weird because it's easy to find on aliexpress/ebay like berkso said, or unsolder it it's easy. you can also find it on arrow, digikey.
for rollershutter mode, no need of very precise data, as it's used as a "switch" sensor, and my sketch, adc sampling/basic filtering etc are using state machine if i remember well, so nothing blocking. there is also available footprints for filtering if needed.
but if you don't have any Ic, you still can use the board, just take a look at the defines in sketch and proceed a manual calibration.
enjoy

My current roller roller Shutter switch are two pushed buttons up and down. No stop button. When release the push button up or down, the shutter will stop. WIll it be compatible with this board or will i have to change the buttons ?
