This isn't exactly a Flipper project per se, but the Flipper was extremely helpful if not integral in completing it so I figured it might be appropriate to post here.
I'm using a Raspberry Pi as a smart hub to control various "dumb" lights with radio frequencies. That's where the Flipper comes in, I used it to capture and analyze the RF signals of the different commands for the different lights. I then wired up an RF transmitter to the Pi and wrote a Python script to send out the signals based on the given commands. I'm using Node-RED and a Discord bot to communicate with the Pi. I'm pretty stoked on it and I hope my writeup can help someone else out there with similar projects.
