I have a lovely Genie garage door opener (I couldn't find a model number but it looks like this) that I've been wanting to upgrade for a while. I'd like to open it with an RF transmitter attached to a Raspberry Pi, as I'm uncomfortable wiring the Pi directly into the opener as some tutorials suggest.
I have been using a Genie GT90-1 remote to open the garage for years, and it seems as though it should be simple to use LIRC with an RF transceiver on the right frequency. This is where I've run into trouble, because while the opener and remote appear to operate on the 390 MHz frequency (reference one and two) I am having trouble finding any sort of 390 MHz transmitter/receiver that will connect properly to the Pi, most devices operating at 390 MHz appear to be Genie replacement remotes.
Is there any way I can make this project work, or is it DOA? The main obstacle seems to be finding a transmitter and receiver. Can I use something of lower/higher frequency, or some other alternative?
