Up/down switches for roller shutter

(Stephane BUISSON) #1

Does anyone had found a solution to command up/down a roller shutter ?
ideally small enough to fit in the wall box behind the mechanical switches.

Sonoff ? (sonoff basic (1 IP) with a second relay on pin 14 with Tasmota firmware, or is that too complicated), thank for your help …

I have thought about using these. They have remote control that perhaps can be hacked. One controller can also be programmed to control multiple windows.

I am trying to stick with Google Home. I don’t know that tasmota directly will support GHome.

I am having difficulty determining what roller shades to use with these. They need hollow metal tubes and everything so far that I found have solid cardboard tubes. I am also not sure what size tube to buy for these.

I have also read that Ikea is coming out with smart shades that are GHome compatible.

thank’s @donkjr, but the roller shutters are already in place with mechanical switches (2 push buttons, not On or Off). I would love to replace those with a remote one (from bed), and still be able to have a mechanic one next to the shutter. (I just find out some chinese products (Xiaomi Aqara) are too big to fit the EU standard wall box, another parameter to take account of).

my shutters are the type with slots in for daylight, if not completely down they let some light to go trough. so I would like to “say/ask” put the shutter X% or full up full down day/night/siesta (based on full operation time/cycle).

as per standard (xbee, etc …) I would prefer to stay just IP/Wifi (like sonoff) an be free to any proprietary softwares or big data (Snips voice control) in case I lose internet (which happen in my country side).

As per home server my research lead me to Jeedom or Hass.io at the moment, still digging.

but I have to say, it’s big bit to swallow, a lot to read and learn … more I dig in more I realise my goals are very basic in terms of devices (few on/off unit, media center, temp control) , but the scenarios (scenes) on server side.

MQQT, NodeRED, home server, Snips, … plus huge amount of other things to read & understand before discarding them. If only I could find a good article to summarize all these techno with +/-.
We are not here yet, but I dream of home server’s graphic UI (OS dedicated to home use make a lot of sense to me in terms of devices/unit, users&group, events , security), where you pick and set your components, link them with arrow (function), then create your scenes yourself with no coding. (dream vs nightmare)

fit in without enclosure, could fit in with enclosure with a bit of persuasion.

EU box is 90x70mm.

I had a similar problem in that I wanted to turn on my bed heater remote so that I could have it toasty when I arrived for bed. I did not want any chance a wifi hack could turn on a heater so I used a 433mhz controller with a fob that I keep next to my TV chair.

I ended up hacking the control panel on the bed heater and inserting a relay(s) where the up down buttons were.
I found a RF remote control and controller with a fob (car remote like) to turn the beds on. You can have four functions.
Perhaps there is some combination of this setup albiet manual-remote not voice that would work for you.

However while getting a link for the above from amazon I found this up down remote motor controller that could be wired directly to your shades motor? I notices quite a few versions of this type of motor controller.

@donkjr Don’t think 433MHz is safer than WLAN. It’s the oposite. Most cheap 433MHz remotes just use a simple ASK modulation without any encryption. They just send one code for on and another for off. Anybody in the receiption area could capture your on/off code and send it out when they wish.

I agree but I am not much worried about my blinds or bed heater being hacked :)!

OK I found a solution witch also allow me to keep the push buttons, the sonoff 4ch describe there :

(Don Kleinschnitz Jr.) #9

How do you plan to control the motors with this?
Configure relays in an polarity reversing format?

(Stephane BUISSON) #10

simple connection as per following design.
the 4ch pro is compatible with tasmota, Mqtt will be the way.
my problem is the size of 4ch pro it don’t fit the wall box behind the push button.
if only it was a 2CH pro …that would have been fantastic.
