I would be interested in the tutorials you followed, I am looking at several and would like to look at a few more.
My goal is Oregon Scientific and other WX station 433.92Mhz devices.
Which receiver did you choose?
But RFSniffer doesn't get anything when I'm trying to sniff my electric gate remote or my electric stores remote although the LED blinks (meaning they use 433 Mhz?).
No, not necessarily.
This applies to the US ONLY. If NOT In the US, then you can just quit reading. I have no clue on authorizations outside the US.
Many garage door openers are at 315MHz in the US, along with some other frequencies for older ones.
If your testing with the devices in close proximity to the receiver... The receiver may be overloaded, and getting enough interference from a 315MHz device at 433.92 to cause the LED to light, but as it can't decode it is not valid data due to being off frequency.
Move the the device under test outside the area of the board, say 20-25 feet, and then retest.
If in the US you look up to see if the device is a 433.92 device by looking up the FCC ID number on the OET site.
