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- Stale-data indicator: out-of-date HA values age automatically - dimmed once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.

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
