I have installed some new lights, and they each come with an identical-looking but apparently differently encoded remote controls. The remotes control only one lamp each.

Not infra-red as I had assumed until just now it seems. Signal hasno trouble passing through walls. Surprising.

Anyone know if there's a way to capture the signals from those remotes and install some USB device on my computer that can repeat them?

I figured there would be when I assumed they were infra-red remotes, coz surely a infra-red flasher/recorder is easy, but now I suspect it's probably some encoded encrypted wifi-band signal or something that there's no hope of intercepting.

@pre If they work without direct line of sight then it’s radio controlled. You could have a look inside the remotes and figure out the transmitter IC, which should give you a hint re the modulation used. After that, the least friction path is to get a HackRF and duplicate the signal from software. Mind you, all this is not trivial.

@rimio Yeah, that sounds beyond me. Fair chance I'd just break the remote trying to take it apart.
