I checked the site for the Jalousier Blind operator, very nice design and also very smart operation.
I assume it will be a lot cheaper than what I used 20 years ago.
I have a Somfy motor about $ 450.00 each then, also have a heat sensor on the window, which monitors the temperature, the sensor is connected to my ADI Ocelot Home Automation controller.
The vertical blinds can either close if its too hot or too cold based on a programmed condition.
Oh yeah, I forgot, I also had to fabricate the stoppers, in order to close the blind when either fully open or fully close.
So, yes the Jalousier is a great idea.
