Automatic blinds / Somfy?

In my case I got this AB, on the backside it says IO

As far as I know io is a somewhat newer protocol. Rts is a older protocol, looking at your AB is looks a little bit older. Maybe you can ask Somfy customer service if they know what you have.

Okay, i’ve managed to get the supplier of the blinds and they could figure out what kind of system it is based on the remote control unit.

It’s the following:

  • fequency 433,32 Mhz
  • Asa ETR & ETR-A devices

So it is safe to say i’m fced, right? There is no app for this in the store.

How hard is it to for example get a version of one of the apps above and change this to this brand? Is it just changing hardware ID’s and some pictures, or do you actually have to work with spectrum analyzers to analyse the frequencies which are send to the device?

There is a Tool in Homey Developer that maybe can help you:

I thought that was just for internal facing emulation. So record en play as incoming signal, it doesn’t push out the commands.

Have you tried the ‘Brel’ app as suggested above?

Yup, doesn’t do anything unfortunately. Has a complete other way of paring, or seems to be like that.

Need to press up and down button to pair. But don’t know how to pair these, so did exactly what it suggests, but doesn’t do anything. Neither does pressing the button on the bottom side.

If you have any thoughts, please do share

Different question; Would it be possible to add a ‘dimmer2’ from Fibaro or even a smart implant to the rollers? This way i could circumstance the remote and just to it by Z-wave, right? I haven’t opened the rollers yet, first wanted to check if it is a possibility.

Hey Martijn, ik heb dit opgelost door de originele receiver eruit te slopen (ook een of ander vaag merk). Vervolgens goed in kaart brengen waar elke kleur draad heen loopt en hoeveel het er zijn. Dat uittekenen, zodat je weet wat je straks moet aansluiten. Tot slot heb ik er een ASUN650 (KAKU tbv zonwering) tussengezet. Zeer waarschijnlijk is dit inmiddels ook mogelijk met een Z-wave module.

Hey Martijn, I solved this by removing the original receiver (a non-supported brand). Next step was to map the original wiring (how many wires, what colour goes where, what’s the function). Then at last I used an ASUN650 (KAKU for sunscreens) to have the same functionallity, but with Homey-support.
I guess there’s also a Zwave module for this task.

The thing is, the sunblinds here have no wall-socket. So there is no place I can put in the ASUN650, I have not tried opening the outside unit, because that seems to be a bit hard being it build in the wall pretty tightly.

I think I’ll have to push the button … …

Ok, that makes it a bit more difficult, but I still think it can be done. In the end you’re only exchanging the current internal
device for the ASUN, which gives you domotica-options. The current device should be replacable, because after all, it will not have eternal life. Also for maintenance it should be possible to acces the electronics. If you want, I can have a look at it. Just to see if it is possible. If it works here, it should also be doable at your situation. If you want you can also have a look at how I did it here. Maybe it gives some ideas!

Make sure to pair any 433MHz device using a crispy new power supply on your Homey.
Been there, done that… and it worked for me.

Yes, I know, but it has this. Unfortunately none of the apps work.

@Koert_Walraven I have removed the ‘kapjes’ (?) but all electrical stuff had been built into the wall. I cannot get to it. So either have to completely replace the blinds (€€€) or find a way to emulate the 433mhz signals, which is no option currently in Homey… Again, i’m forced to use a button…

Or maybe some day, the “Microbot” will be an option (isn’t available in Europe for now)

Maybe a broadlink rm pro is somthing for you.
IT can learn 433mhz.
There is also an app for homey

That sure sounds like a solid idea! Then there is no position calculation, but it just replaces my remote buttons. I have looked for the device, but it seems a bit hard to find a webshop who sells them. I can find the mini, but that only does IR.

Does this seem like a trustworthy shop?

This is the RM4, there is also, which one do you advise?

mmm… it seems the latest devices are not supported and the developer is not responding. …

Sounds like a difficult situation. Let’s hope that the build-in electronics stay alive, because even with an emulator, it still depends on the “old” hardware for receiving/interpreting, so if that goes to electric heaven, than you still stay in the monkey (in de aap gelogeerd) :wink:
If I find a solution, I’ll put it here. And the offer of having a look at it, still stands, should you be willing that.

You must buy a old version to make it work

I’ve been looking for such a device, but it’s a complete gamble. I have looked for it on marktplaats (dutch site to sell and trade rubish) but there was only one advertisement and it got pulled when I made an offer, I assume he already sold it.

Since there is no way to know if you are buying a new or old model, i recon most stores have new models. This sucks.

There was mentioned some guy managed to get the pro4 working through MQTT but, that is a lot of effort and a lot of components…



I still read it doesn’t work on homey though…

It’s been a while since I last posted in this topic, but I managed to solve it.

I have bought the Broadlink Pro (all versions are supported nowdays using the community store apps). Unfortunately the BroadlinkPro doesn’t support rolling encryption systems. Copying the remote does work, but since there is a rolling encryption the copied remote changes and thus doesn’t work anymore.

Eventually I’ve bought a RFXCom433E and with this I can add my ASA blinds. It is a bit of a hassle because Homey doesn’t support it, I therefor have added them to Home Assistant and pushes the devices back to Homey. This works great.
