Fully agree that not everything needs internet access, but you listed some useful ones. I don't think this is actually a hardware company at all, to be honest.

Fully agree that not everything needs internet access, but you listed some useful ones. I don't think this is actually a hardware company at all, to be honest. The actual hardware here is practically trivial, like an ESP8266 that bitbangs the legacy interface. Hopefully some tinkerer would design some PCBs once and just release them as CC, problem solved forever. It's fairly straightforward to send a request to the adapter node and have it do a thing. Again, a hobbyist could probably come up with a reasonably coherent protocol in like an hour or two. There is some small value in a company that can make the act of pairing less painful for consumers, but tinkerers probably won't care. The actual hard part is coming up with software that does useful things with those peripherals/API. He's selling an app, basically.
