Hi I am graduating and had a project to control my sunshades with a android tablet. After searching the internet I found Openremote. This project is great and I have used it as basis for my project. Finally I added a new protocol/plugin to control my Somfy RTS sunshades. And it's working as you can see in this video http://www.youtube.com/watch?v=q8YSP8nRsnI&feature=plcp

At this moment the controlling of the sunshades is done by a regular telis 4 remote with some extra hardware. I needed some learning curve and had to design software and hardware. So I didn't choose to use the 16-way multi-controllers from Somfy itself. But my solution is also expendable to make it a 24 channel remote if I want by adding some regular telis 4 remotes.

I had some nice comments and was asked to drop a post on this forum. So feel free to ask questions if you like to know more about this project.

Hello Mark,

Thanks for getting in touch, would definitely like to understand in more detail what you've done and whether it would be useful to share with the community.

Please feel free to email me directly: juha at openremote dot org

Best regards,

– Juha

I also have Openremote and Somfy RTS at home. I actually also had some hardware in mind building of a Telis remote. I would be glad to have a look at your hardware design if you would like to share it.

Hi, i also have some Somfy RTS motors and am intrested to hear how you guys hacked the telis remote. do you simulate button presses with relais or somthing like that ? I ve looked at rs-234/rs485 rts interfaces but found them way to expensive.

Hello Juha,

it look's like an hardware/brick-remote/soldering/Arduino hack... => http://androidzonwering.blogspot.de/2012/07/doelstelling-week-19.html

so there is no io-homecontrol 128Bit encryption/decryption implemented

He said "Somfy RTS is secure" => http://androidzonwering.blogspot.de/2012/02/somfy-rts-is-secure.html

... it's all on Mark's blog => http://androidzonwering.blogspot.de/

Kind regards
Patrice

Be reminded there are different versions of the Telis remote around. There are some pictures on the internet showing how to solder the wires. Unfortunately on some models the switches have been rotated 90 degrees. So do measure the connections of individual pins to the power source. I found the device has pull-up or pull down (I don't exactly remember) resistors of about 10K. If you want to do it cheap, you have to solder unfortunately. I am looking into a solution using Z-Wave, which I hope to do for under 100 Euro. Maybe I know more in a month from now.

This might be a solution which does not require soldering the remote http://www.automatedshadestore.com/shop/product-info.php?pid324.html

Yes, I agree. But close to 400 USD is quite a bit. Dismantling a remote is for the poor man's solution. I am presently looking into cheap devices similar to the Flyport Ethernet (http://store.openpicus.com/openpicus/prodotti.aspx?cprod=015356) which are in the price range of a Z-Wave module. On the other hand they are so powerful that it seems a bit overkill for simulating only three buttons.

Here is another solution that should work together with some switch actuators: http://www.smarthome.com/318276/Dry-Contact-Interface-for-Somfy-RTS-Motors/p.aspx

That's indeed a box with the Somfy remote inside, and the wires soldered on instead of the buttons. This device still has to be connected to some protocol that OR supports, or if one happens to use a Raspberry Pi to one of the GPIO pins

I described my GPIO solution here: OpenRemote 2.0 How To - Control Sunshades - Somfy with Raspberry Pi
I expect it will work with the Dry Contact interface that Marcus mentioned.

Hi I have just read that there is a new product from rfx which will control RTS blinds. It costs about 100€ so a lot cheaper than the current options.

I am tempted to buy one but would need help with getting it to work with OR. Is someone able to check whether it looks compatible?

Here is the link

rfx

Thanks
Jules

Interesting. From the "supported sevices"specs it looks like it does control Somfy. IIRC there was something funny with rotating id-codes with the Somfy, which made it impossible to do it with an off the shelf RF device.
Because of that I did chose the GPIO solution

Posted by pz1 at Jun 03, 2014 11:02

Reading a few sites it looks like it certainly is designed to work with somfy. I found this link which mentions jsnode which I am already using for my sonos interface do you think that would work with OR?
