Thank you to all that replied.
Let me try to answer some of your questions.
The drapes are operated by a Makita RC10 drapery controller.
By going to RemoteControl.com I found out that it is an IR system.
There is a local set of control buttons but I have never been able to program them and always found the RC10 is more convenient.
Using BVC appears to be inconvenient for my purpose. I want the AHP program to open and close the drapes at dusk and dawn automatically without me having to use a voice command. push a button or even be home, or don't I understand its functions?
The suggestion of the USB-UIRT seems promising but:
1. How can it be programmed with AHP's timers to operate at dusk & dawn?
2. Is it capable of learning Makita's codes?
3. Since it connects to a computer via the USB port does the USB-UIRT have to be in the same room as the drapes (line of sight) or can a PowerMid be used?
I have requested information from the seller.
Thanks again to those who took the time to try and help me. Respectfully, Graphics Guy
