@petewill Hey Pete, this is a great project and I'm trying to do something similar but I had Budget Blinds installed in my new home and they seem to be very locked down to protect the dealer/partner channel. Apparently the remotes and automation stuff are made by Somfy and operate on 433.42 MHz.
I started with the project as you describe in this thread, I've been trying to use the terminal monitor with no real results so my next step is to try using audacity to capture the data. If my equipment operates on 433.42 is this problematic? Is it possible to tune the Arduino receiver or does it operate on a wide enough range to capture that? I just want to create a Vera scene to open and close the blinds at specific times.
I hope it's OK to revive this older thread.
