I am looking on adding a multiple sets of window shades. I think I will go with Somfy mostly based on reputation for reliability and quietness. I will need custom window treatments and rollershutters for my windows as they are odd sizes. I know this will not be inexpensive.
A couple of questions for those who have Somfy systems and have integrated them into OpenHAB (I have not been able to find satisfactory these answers via search here or Google).
(1) Somfy systems seem to have 16 channels. Does this mean you can only control 16 shutters? Or can you put two shutters on a single channel if you don’t want to control them individually?
(2) I wont be hardwiring these, do the Somfy solar panels provide enough charge to not have to charge the batteries? Assuming the blinds are used 1x per day, how much direct sunlight per day does the solar panel need?
(3) There seems to exist multiple ways to integrate a Somfy system with OpenHAB either via Tahoma or MyLink. Is there a benefit to one system vs the other? What sort of range do these systems provide? I have one room - over the garage that can be hard to reach with centralized wifi, etc.
If the goal is a highly reliable system with minimal maintenance (including battery swapping) is there a better system to look at besides the Somfy system?
