Somfy blinds in 2025

What's the best way to control Somfy blinds in 2025. What options are available, and what type of blind motors do I need? Thanks

 

Hi,
Yes always use 240v motors and control them with shutter relays.

 

Yes but how does it work? Do I program a time into Cbus or do they have hall sensors or what?

 

C- bus shutter relays have timers to cut off supply and a timer between changing direction. The blind typically have travel limit switches which are set on installation.

 

So can I use a relay unit to control up and down functions I wonder?

 

yes the c- bus relay can provide up, down and stop feature.
but you need to purchase a blind motor that has the ability to be controlled via normal switches hence electrical control, not data control

 

Hi Tension,

With sites operating with a Shac/Nac - Look into the Bond Bridge unit to allow for RTS control without the need for Shutter controls. Bond Bridge have an API

BLW

 

Thanks. I've ordered an extra battery powered handheld RTS remote, I'll open it up and solder wires to the buttons and connect it to some spare relays. Hopefully I can trigger them as a kind of doorbell press to open and close.

 

So I've hit a snag. On my eDLT I want to use a single dual mode button with one side of the button to activate the 'close' relay, and the other side to activate the 'open' relay. It seems if I set the function on the eDLT to doorbell press, it forces both sides of the button to do the same thing, which is no use. I don't want to use two separate buttons.

Am I missing something or will I need to just buy a shutter relay?

 

Does the button have short and long press options, that might work if it does.

 

Doesn't seem to unfortunately.

 

Can you make it a new page button and put the 2 actions on that page.

 

Could do. But that's not a very elegant solution. Each button on an eDLT has 2 potential functions.

 

No idea about the eDLT or blind motors, but on the DLT I use a timer funtion instead of bellpress.
Press button, led on, a couple of seconds later off. This means it stays on long enough for people to see and the old piced logic to detect.

 

I'm not familiar withball the logic stuff. Just working everything out as I go along. I'll just get a shutter relay I think
