ZMK — gates and doors

ZMK is a remote in your phone. Barrier, gates, entrance door, garage and lights — one button, directly over Bluetooth, no internet. One big button: press it without leaving the car, and the barrier goes up. You add the devices yourself and name them as you like. With a single device the screen stays simple: one button, nothing else. From the second device on, pages swipe sideways — Barrier, Entrance, Garage. How it works The app talks to the controller directly over Bluetooth, like a remote. No internet, no servers, no account. All you need is the device code, which your building administrator or the device owner enters on your phone. What matters • Works with no network. Underground parking, roaming, mobile data off — all the same. • A Timer for lights and other appliances: switch on and off from your phone, a weekly schedule and a hold-to-run mode. • "Open: …" shortcuts: long-press the app icon and the right device opens with one tap. • Collects nothing and sends nothing anywhere. Device codes and controller addresses are stored on your phone. • The code is never shown on screen. The administrator enters it and the resident never sees it — so it cannot be passed on. • Every device has its own code. The barrier is shared by the whole building, the entrance by one stairwell, the garage only by you — a neighbour who knows the barrier code cannot get into your garage. • No ads, no in-app purchases, no sign-up. • Existing remotes keep working. The app complements them. • Only someone with the code can open the gate. The code is never sent over the air in clear text: the phone signs a random number that the controller issues anew for every connection, so a captured message cannot be replayed. • The code can be changed from the app while standing next to the device — no need to remove the controller or attach a laptop. That requires the owner's master code. • Russian, Kazakh and English, chosen by the phone's language and switched with one tap on the main screen. Requirements A ZMK controller on the device and the code, entered by your building administrator or the device owner. The first time you tap OPEN, the iPhone asks for Bluetooth access — without it the app cannot find the controller. Location is never requested.
