ejn1 Posted November 24, 2016 Share Posted November 24, 2016 Appreciate if anyone has a view of what's the best way to integrate a somfy blind system? I know previously I was looking at their RTS rs232 interface but something tells me their is a newer better way to integrate? Link to comment Share on other sites More sharing options...
VINCELdUB Posted November 24, 2016 Share Posted November 24, 2016 For wireless blinds, the URTSii is the best option. However, there are issue associated with using a wireless system. I have Ahmad some blinds in same room randomly nor receive signals while ones next to it work. I would call it a 85% perfect solution. I found that I would use a rs232 to rs485 adapter to allow me to plug into a controller far away and have the URTSii in same area as the blinds. Using cat5e or other wiring. Rs485 only requires 2 conductors and can be small gauge in most cases. I guess I should have started with; Are the blinds already installed and do you have an option to run alarm wire or cat5e wire to each motor still?

I have a hc800 in the same room so was thinking about putting that Somfy URTSii controller connected to the hc800. I thought I saw that Somfy was some new wifi interface and app so didn't know if there was a better solution. It's worrying your comment on random reliabiliy... thanks!!!

VINCELdUB Posted November 26, 2016 Share Posted November 26, 2016 How may motors do you want to program? Also, the wifi interface would be the same. It is a URTSii with a network connection instead of the rs232 interface. For control4, the rs232 to your controller in the same room should yield good results.

VINCELdUB Posted November 26, 2016 Share Posted November 26, 2016 If you want 6 individual controls then the URTSii is the one for you. If they already operate one one or two channels on an existing somfy remote or keypad then there is another product. A single channel remote the connects to the relay output on the hc800 controller. This is more reliable than the URTSii but is limited to one channel per device. https://www.somfysystems.com/file.cfm/Dry_Contact_RTS_Interface_1810493.pdf?contentid=199692 This is what you want. It uses two of the relays on hc800 but works flawless. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

I have no means to run any wires to the blind location so think URTSii is the only option for me. Link to comment Share on other sites More sharing options...
VINCELdUB Posted November 26, 2016 Share Posted November 26, 2016 Sorry. This can sit on top of your rack at the controller. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
VINCELdUB Posted November 26, 2016 Share Posted November 26, 2016 No need to run wires. The short tail from device will plug directly into the hc800 Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
