HassDataFace

PV HASS Face - Home Assistant data on your wrist A clean watch face with a central clock and date surrounded by 8 fully configurable fields. Each field shows either a built-in watch metric or the live state of a Home Assistant entity - ideal for solar/PV production, hourly energy balance, and any other sensor you expose. It ships with a ready-made solar + energy-balance layout that you can fully re-map. IMPORTANT - read activation info first! FEATURES - Central clock + date (with a selectable clock size), 8 independent fields arranged around it - Optional second screen: a double wrist-raise (or a tap on touch models) switches to a second page with 6 more fields (F9-F14, 14 in total) and two mini charts that plot any field's recent history as a line or bars - Each field: choose a built-in metric OR a Home Assistant entity - Built-in metrics: Time, Date, Seconds, Battery, Heart Rate, Steps, Calories, Floors, Distance, Active Minutes, Notifications - Home Assistant: all entity-backed fields are fetched in a single efficient request (template API); updates run in the background - Icons for built-in metrics, or your own text label instead - Goal / progress visualizations, with the max taken from the system goal or a manual value: * Rings around fields * Two rim arcs that you can assign to any field (with an optional label/icon) * Horizontal bars that fill left-to-right or right-to-left depending on the goal's sign - perfect for signed values such as energy import/export - Adaptive layout: disabling a field lets its neighbours use the freed space, without ever clipping at the screen edge - Per-field font size, custom label and unit; optional fixed decimal places for numeric Home Assistant values - Configurable colors: labels, standard data, Home Assistant data, clock, date, and background - Optional live system seconds with a progress ring - Configurable refresh interval (5-60 minutes) - Night mode: on a schedule (default 19:00-08:00), slow the HA refresh to a separate interval or turn it off entirely to save battery - Stale-data indicator: out-of-date HA values age automatically - dimmed once stale, then shown as "--" after an hour - so you always know the data's freshness - Settings organised into clear groups in Garmin Connect / Garmin Express ACTIVATION - Reading Home Assistant data is unlocked with a one-time activation key. Until then the face runs in demo mode: HA data is shown only 1 minute in every 3; the rest of the time the HA fields read "***" and the device ID takes over the lower fields. The device ID needed to obtain a key is shown read-only under Settings - Activation, and in that demo message. Built-in metrics (battery, steps, heart rate, etc.) work without a key. - You are welcome to request the key for free (use "Contact Developer" form, provide device ID). During test period limited quantity of keys will be available for free so I can test the face on multiple devices. I will appreciate feedback for such free version. - You can also support my work on: https://ko-fi.com/998vsid CONFIGURATION (in Garmin Connect Mobile or Garmin Express) - Home Assistant URL and a Long-Lived Access Token; activation key - Per field: source, entity_id (for HA), label, unit, font size, icon on/off, gauge on/off, decimal places (for numeric HA values), and goal/max (may be negative for the bar fields) - Arcs: pick which field each rim arc shows, plus an optional 3-char label - Charts (page 2): enable/disable the second page; per chart pick the field (1-14) it plots and the type (line or bars) - Night mode schedule and night refresh interval - Clock size, colors, and refresh interval REQUIREMENTS - PLEASE READ - Reading Home Assistant data requires a one-time activation key (see ACTIVATION above). The rest of the watch face works without it. - Your Home Assistant must be reachable over HTTPS with a publicly valid certificate

- Second screen (charts): a quick double wrist-raise switches to an optional second page (a tap also works on touch models). It adds 6 more fields (F9-F14, for 14 in total) and two mini charts that plot the recent history of any field as a line or bars. Turn it off entirely if you don't want it. - Demo mode replaces the old lock screen: before activating, Home Assistant data is now actually shown - but only 1 minute in every 3 (the rest of the time the HA fields read "***" and the device ID takes over the lower row). Enough to test your whole setup before you get an activation key. - HA decimals: choose a fixed number of decimal places, per field, for numeric Home Assistant values. - Smarter stale-data handling: out-of-date HA values now age automatically - dimmed once stale, then shown as "--" after an hour (the old on/off setting is gone). (Earlier additions: night mode, activation, assignable rim arcs, clock size, and adaptive layout when a field is disabled.)
