All it takes is money....
I know Somfy makes a RS-232 interface for their system (at least the hardwired systems). But I believe it is around $500. Of course you have the cost of the motorized blinds and power supplies on top of that as well.
I don't know of an inexpensive solution out there.
Yeah, I think this project, for the shutters, will be pushed to the back burner. In part, because of money, but mostly because I'll have to run power to each window, requiring drywall/paint. It's in the plan for the next 2 years, to repaint that room (and do a partial kitchen refinish - 1 continous, large room), so I guess I'll have plenty of time.
Now, though, I can experiment with using linear actuators on the stereo cabinet side doors, for ventilation.
Is it really this simple, though? DC linear actuator controlled by IR-equipped controller? IR code 'learned into' universal remote? Actuators and controllers seem to run ~$100 each.
What devices would I use to incorporate temperature-regulated control?
