It's fine to continue the discussion here, since others may be interested. Do you have the Raspberry Pi's TXD pin connected to the base of Q2? That pin is normally...

My garage door opener limits current to about 150 mA, so I didn't bother adding a current-limiting resistor on the 12V line. Perhaps a pull-up resistor on the base of...

If you want to force a particular device, you could open up the flow graphs and fill in the "Device Arguments" property of the osmocom Source / Sink. It could...

I don't have a WiFi bridge, and haven't investigated the opener's WiFi communication. However, I have confirmed that the door status is transmitted in wireline packets. (Some details are here:...

Yes. Open secplus_rx.grc in gnuradio-companion, then edit the frequency list in the "QT GUI Chooser" block. Then press the Run button to execute the modified flow graph.

If 433 MHz works, let me know the exact frequency and I can add it into the program for everyone.

Make sure you execute `secplus_rx.py` from the project's root directory (i.e. the directory containing secplus.py).

If you start `gnuradio-companion` from the command line while in the project's root directory, it will probably work in GRC as well.

I'll add the frequency if and when it's confirmed to be used by actual hardware. If you can't figure out how to edit the flow graph in GNU Radio Companion,...

Were you able to decode any remotes at that frequency? If so I'd be curious to know what the model numbers are.
