Re: Remote Garage Door opener
"P.S. They have actually existed since 1950s, also if you are IN the car, needing to use a phone app is a retrograde step from models fitted on a car."
Back in the day, 1982 or 1983, my dad fitted an opener for our garage(1), remotely triggered by a short-range radio widget clipped on the driver's side sun visor. No third-party servers (FFS the ARPANET had only just switched to TCP/IP), no WiFi, nothing like that.
(1) The less said about the placement of this garage the better, mostly because sane people would use highly bleepable language. A previous owner of the house had demolished a ground-level garage beside the house in favour of digging a hole in the ground, knocking a hole in the side of the house, and converting that end of the basement into a garage. The result was that in heavy rain conditions, the drywell under the lowest part of the drive backed up and the drive flooded. My parents bought a submersible pump for it, but even with that, on one memorable occasion we baled it out because the pump wasn't able to keep up.
