The biggest maker of garage door openers in the U.S. has done the same thing. For a button that goes on the wall to open the door, now it sends an encrypted code instead of just shorting two wires so that you have to use their button instead of a regular doorbell button like people have been doing for decades.

I can't recommend ratgdo (Rage Against the Garage Door Openers) project highly enough. It implements the protocol and allows you to interact with the door: https://paulwieland.github.io/ratgdo/

The protocol itself is crazy, with obfuscated ternary data (instead of binary). People who reversed it are heroes.

Which company, and which product did you see this with?

[cameldrv]

Chamberlain and Liftmaster do this. They’re both owned by Chamberlain group and I believe they are the two most popular brands.

It’s caused tons of headache for people doing home automation stuff, especially since Chamberlain has cut off API access to home assistant. Then the home assistant people figure they’ll just rig a raspberry pi or something to short two wires, but then they hit this encryption nonsense.

That's nuts!

For what it's worth, I bought this for my old chamberlain. https://gotailwind.com

I was looking into replacing the old unit with a new one with myq but then read about all the problems and decided to give this a shot. 3 years in and it's been a good decision.

Heh, bet you can just short the contacts the button usually closes. Really hard to DRM a button.

Chamberlain devices do this. Genie devices do not.

Genie is nice; you can add Homekit with any of Meross's garage door doodads for $50ish

I blame it on cybersecurity experts lol. They probably went all alarmist and decided that having that was a giant security risk.

God that's just insane.
