One thing people don't realize is that the custom firmware [0] that you can run allows you to receive and transmit on a wide range of frequencies under 1Ghz. Lots of things use that range (garage doors, gates, fan remotes, etc.) and are not very secure. I think that this will be a time looked back on where it's possible to interact with those devices without having to buy a custom PCB transmitter or somewhat expensive and complex SDR.
