I'm trying to remote control some power outlets with my Raspberry Pi and I'm following the tutorial from this page. However, I have been unable to get any output from RF sniffer, I have 3 RF receiver/transmitter sets, and neither have worked. I've tried them on a Pi 2 model B and a Pi 3.
This is my terminal output after trying to reformat my Pi 3 and installing all the requirements.
My connections look as follows:
I have no idea where to start with troubleshooting, since I am a programmer. I have checked the source code for RFSniffer and codesend, and it seems to connect to the correct pins. However, when I use Python to print the value of GPIO pin 27 it seems to give 0s and 1s intermittently.
I have read that this might mean that it registers no connection, or can it mean that there is some radio frequency being registered? I am unable to discern any difference in the output by eye when I press buttons on the remote or use codesend to try to send codes.
Is there any way for me to detect if it receives anything at all, or any other pointers as to what is wrong?
Thank you for reading.
