ratgdo Garage Door Controller

The ratgdo exists because of a cloud shutdown: when Chamberlain cut off third-party access to myQ in 2023, this small board — "Rage Against the Garage Door Opener" — became the community's answer. It wires directly to Chamberlain/LiftMaster openers (or any dry-contact opener), runs open-source firmware, and needs no account, no subscription, and no vendor server. As a hedge against exactly the kind of lock-in that killed its predecessor, it is one of the most BIFL-minded devices in the smart home.

Ring Video Doorbell Pro 2

The Ring Video Doorbell Pro 2 is Ring's flagship hardwired video doorbell, pairing 1536p Head-to-Toe HD video in a tall square aspect ratio with radar-based 3D Motion Detection and a Bird's Eye View overlay that maps how visitors approached your door. It wires into an existing 16-24 VAC doorbell transformer, so there is no battery to degrade, and it connects over dual-band Wi-Fi. As a piece of hardware, it is one of the most polished and durable video doorbells on the market, and that build quality is why it appears in this directory at all.

Aqara Door and Window Sensor P2

The Aqara Door and Window Sensor P2 is a small Thread-based contact sensor that reports whether a door, window, drawer, or cabinet is open or closed. Unlike Aqara's older Zigbee sensors, the P2 speaks Matter over Thread natively, so it pairs directly with any Thread border router and Matter controller, an Apple TV 4K, HomePod, Home Assistant with a Thread radio, or a SmartThings hub, without ever touching an Aqara hub or the Aqara cloud. Pairing is a QR-code scan, and from that point everything runs on your local network.
