Secplus for 433Mhz?

[KjellKriminell6]

hi! I would like to use 433Mhz in Europe. Would that be possible? thanks!

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.

Thanks for your reply!

It works fine changing the QT GUI Chooser. But when trying to execute, I get an error saying "secplus_decode Param 'Code' Can't interpret source code: No module named secplus"

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

[KjellKriminell6]

Thanks argilo. When I execute sevplus_rx.py from terminal it works fine but I can not choose 433MHz. When trying to execute secplus_rx.gnu inside GNU Radio I get the error mentioned above, "secplus_decode Param 'Code' Can't interpret source code: No module named secplus"

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

[KjellKriminell6]

No, sorry, starting gnuradio-companion in CLI in projects root folder did not erase the errors mentioned above.

I would really like to try this script at 433,92Mhz, can you add that frequency please?

[argilo]

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, then open secplus_rx.py in a text editor, and change the frequency lists on lines 92-95:

[KjellKriminell6]

Thanks a lot, that worked out great adjusting it to 433,92MHz! Keep up the good work!

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