A lead QA engineer transforms basic garage door controls into an intricate and personalised home automation system, integrating gates, alarms, a vehicle, and household systems using Home Assistant and custom routines.
What begins as a simple wish to open a garage door from a car screen soon becomes a much wider lesson in how home automation behaves when it meets real life. In this case, the writer, a lead QA engineer who spends his working day automating software flows, started with one practical aim and ended up building dozens of routines across gates, alarms, a car and household systems. The result is less a novelty and more a carefully tuned set of controls that turn repetitive movement in and out of a building into a predictable sequence of actions.
The most technical part of the system centres on Alfred Smart, the access-control platform used in the writer’s building. Alfred Smart says its system is designed to work across protocols including Zigbee, Z-Wave, KNX and Wi‑Fi, but the writer’s building app has no native Home Assistant link. By inspecting the web app’s network traffic, he found a straightforward REST setup: sign-in returns a JWT, and each gate opens through a single device-interaction call. That allowed him to recreate the process in Home Assistant, while also automating token refreshes before the credential expires.
From there, the logic became more refined. Different entrances now trigger different gate sequences, with delays adjusted to fit the route actually taken on foot. The timing was not guessed once and forgotten. It was measured repeatedly and then exposed through editable helpers so the labels and delays stay in sync. The mobile prompt that appears when he is within range only fires if GPS accuracy is good enough, which avoids false triggers from nearby places such as the gym. Home Assistant’s own handling of location accuracy makes that kind of boundary testing necessary, and the writer has used it to keep the automation from behaving too eagerly.
Security is handled through Verisure, linked into Home Assistant with the Securitas integration, which Home Assistant’s documentation says can expose alarm states and related controls, including lock functions and autolock actions. That gives the system a cleaner model than the original app, with clear modes for disarmed, partial and full arming. The writer also extended Home Assistant’s reach into his Toyota, using a HACS-based integration for vehicle status and a separate command layer to add lock and unlock support. That in turn enabled reminders if the car stays unlocked too long, plus timed responses to arriving and leaving routines. He now runs the whole setup on Home Assistant Green, with a YAML-first configuration and a dashboard built from Bubble Card and Mushroom.
