💬 Roller Shutter Node
-
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 :+1:
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 . .

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.

@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 :+1:- 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

well, it is a zener, not wheeling diode, which should be enough..

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
-
Dont Care :-) its cool. Zenner its not enoth but dont worry. I need it .. the nrf is verry "female" :-D (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.

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.

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 -
Hi, I make this project, pretty cool.
How I can upload the firmware? What I need to do?

@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.
- in arduino ide, program bootloader (for these, i used the sensebender board in Board manager).
- 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 ??

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 :

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

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.
