[Hai-users] Somfy blind control

[Dan Hoehnen]

These blinds also have tilt control, as well as up/down.  Do yours have
up/down only, or tilt too?

The DC5 spec's say that a contact closure of less then .5 seconds is needed
to start the blind going up or down.  But, a closure longer then .5 seconds
is needed to start the tilt (for horizontal blinds).  

I guess if you are not doing tilt then the 1 second resolution may be fine
for up/down control.

If you are also doing tilt, please give me a quick scenario of what you do
with contact closures to activate up/down and tilt features.

Thanks so much.

Regards,
Dan

I have the Somfys.

the 1 sec value works fine with the HAT. It is what I use.

400 ms is probably a minimum... 

It works well and I've had no problems. The somfys are very nice.
