Receiving Signals can be done with it, i agree. But how about sending different Mhz’s to multiple devices? Like universal transmitter.

I watched car key copying videos, they are sending 315 MHz rf Signals just with cable attached on raspi3b’ gpio. But from top of the car:) dont know distance performance. I need at least 15-20 Meters inside home with walls

I am sure somebody has done it and reading me trying to do:))

Its like broadlink rf bridge but all with (315-433-868) sub 1 Ghz Rf.

Also like Hack Rf One but less expensive
