R1HA is a native Android app for controlling a Home Assistant setup, the open source software many people use to run their smart home. It was originally built for the Rabbit R1, a small handheld device with a physical scroll wheel, and works equally well on Android 11 or newer phones and tablets. On the R1 the scroll wheel adjusts any numeric thing in Home Assistant, such as light brightness, fan speed, cover position, or media volume. On a touch screen the same controls respond to drag and tap. The official Home Assistant Companion app is mostly a web browser wrapped around the existing Home Assistant interface. R1HA takes a different approach: it draws most screens natively using Jetpack Compose, and only falls back to the web view for parts that do not fit, such as the automation editor or HACS cards. The trade-off is that R1HA needs Android 11 or newer, while the Companion app goes back to Android 8. The app is organised into three areas. Awareness screens show at-a-glance information: a TODAY dashboard with weather, time of day, who is home, current media, power draw, and battery alerts; a quick search across every entity; live camera snapshots; weather details; calendar events; recent logbook activity; persistent notifications; rooms and zones; energy production and consumption; and full history charts for any entity. Control screens are for taking action. A card stack with swipeable tabs holds favourite entities. There is a launcher for scenes and scripts, a list of automations with run and toggle buttons, helpers like input booleans and timers, a master OFF for all lights or switches, an Assist conversation entry, and an Android quick-settings tile bound to a single entity. Power tools cover the long tail: a Jinja template evaluator, a service caller, a service browser, a system health view, and the Lovelace web view as a fallback.
