I have a few old Microsoft MCE remote kits floating around. Is there any way I can use the emitter cables that came with the MS kit with the Wemos D1 Mini I am already using as a 433mhz gateway? I already have the IR receiver bit covered by using the same IR receiver cables I built for my Pi/Kodi HTPC setup.
Since the gateway is already sitting near the TV/Amp, it would be handy to add the functionality of controlling these devices.
