About

Telemetra is a precision, data-first watch face for AMOLED Garmin watches, built on native vector fonts for crisp legibility at any size. TWO FACES, ONE DESIGN LANGUAGE - Grid - a dense telemetry dashboard: date/condition header, a metric graph, four configurable data fields, up to four progress rings around the bezel, a sunrise/sunset row and a configurable bottom widget. - Apex - a bolder, focused analog layout with a power line, a left data block, a ring, and hourly bars. HOME ASSISTANT Show up to five Home Assistant entities - temperature, energy price, a door sensor, anything - as data fields on any face. Enter your Home Assistant URL, a long-lived access token and up to five entity IDs in the settings; the watch fetches them in the background and shows each with its friendly name and unit, or a short custom label you choose. Any numeric entity can also be plotted on the graph: samples accumulate on the watch and draw as an auto-scaled line, decimals and negative values included. A stale value is marked rather than silently shown as current. One HA sensor can also override the outdoor temperature everywhere on the face, falling back to the Garmin forecast if it goes stale. Configurable refresh (5-60 min). Requires a valid HTTPS URL (Nabu Casa works out of the box). LOOKING AHEAD, NOT ONLY BACK - Projection Ring - extends one ring with a dimmed arc showing where its metric is heading at the rate it has actually been moving. It stays hidden until there is enough history to justify it, and never guesses. - Rain band (Grid) - the rings pull inward and the freed outer edge becomes an hourly rain forecast mapped onto the dial: a mark at 3 o'clock means rain at three. Brighter means a higher chance; dry hours leave a gap, so the shape of the band is the forecast. Choose its source: Garmin's own forecast, Open-Meteo (free, no account or API key), or your Home Assistant weather entity. - Day Shape (always-on) - your day's step profile as a closed 24-vertex polygon, one vertex per hour, with a brighter dot on the current hour. Different every day, because the day was. FULLY CONFIGURABLE Every slot picks from 26 metrics - heart rate, resting heart rate, steps, body battery, stress, VO2 max, calories, floors, distance, intensity minutes, recovery, respiration, pulse ox, sleep score, training status, notifications, battery, battery days, date, weather, sunrise/sunset, and the five Home Assistant fields - per slot and per face. RINGS AND GAUGES - Up to four rings on Grid: left, right, top and bottom. - Four ring geometries: Round, Flat, Wire (thin arc with a bright head dot) and Dashed - each composes with every colour option and every theme. - Ring colours: white, two accents, ten fixed colours and seven gradients (Aurora, Ember, Fade, Glacier, Plasma, Sunset, Toxic), per ring. - Gauge labels: Word (STEPS 58%), Numeric or Off; label colour Faint, Accent tint or White. MORE - 20 colour themes. - Presets - Everyday, Training, Trail, Minimal and Instrument, plus three save-your-own slots. A preset never wipes your Home Assistant credentials. - Configurable graph: metric (built-in or Home Assistant), 1-24 h range, line / bars / off, auto or manual min-max scaling, and an optional background (lines, grid or dots). - Grid bottom widget - classic data row, sun arc, recovery countdown, 7-day step history (days that hit their goal are marked), sun countdown, or a 7-hour rain forecast. - Five always-on modes (dim-full, clock-only, analog, big-clock, day shape) with a Thin or Outline clock style, tuned for AMOLED burn-in. - Battery indicator (text, bar, or bar only). - Full on-watch settings menu - change anything without your phone. - Native vector fonts - sharp rendering, low memory. SUPPORTED WATCHES fenix 8 (43/47), fenix 8 Pro (47/51), fenix E, Forerunner 965 / 970 / 570 (47) / 265, Venu 3 / 4 (45), Epix 2 / 2 Pro (47/51).

What's new

========================================= HOME ASSISTANT SETUP (optional) ========================================= 1. In Home Assistant: Profile - Security - create a Long-Lived Access Token. 2. In this face's settings (Garmin Connect / Connect IQ app): paste your HA URL (HTTPS with a valid certificate — Nabu Casa works), the token, and up to 5 entity IDs (e.g. sensor.living_room_temperature). Each can have a short custom label. 3. Assign "Home Asst 1-5" to any data slot, or pick one as the graph metric. Values appear within your refresh interval. The phone must be connected and online. ========================================= PERMISSIONS ========================================= Communications — fetch Home Assistant entity values over HTTPS, only to the URL you configure; and, if you select it as a weather source, an hourly forecast from open-meteo.com for your approximate location. Background — refresh those values while the face isn't active. Positioning — sunrise/sunset times, and the forecast location if you use Open-Meteo. User Profile — VO2 max, resting heart rate. Sensor History — heart rate / stress / elevation graphs. ========================================= WHAT'S NEW ========================================= 0.7.3 — Fixed: changing any setting from the phone could silently reset the whole face to the last preset you ever applied there. Presets now apply only when you actually pick one (to re-apply the same preset, select None first; the on-watch Presets menu is unchanged). New Theme Accents setting (Both / Left only / Right only) paints the whole face with a single accent - try Ember + Left only for pure signal orange. Also: Home Assistant values and the rain band refresh at full rate again, no more phantom step spikes in the graph after a workout, and saved custom presets need one re-save. 0.7.2 — Fixed: the heart rate graph averaged your workouts away. It now fills gaps from the watch's own recording and keeps the peak, so an hour you trained in reads as the effort it was instead of your recovery pulse. The top forecast row is now three larger cells or four compact, your choice. New Ember colour theme (orange). Pressure now shows its trend arrow in the extra field row too. 0.7.1 — Fixed: forecast widgets never loaded on Open-Meteo or Home Assistant, and background refresh could starve on a watch in regular use. Forecast Source moved to the Widgets menu. 0.7.0 — Weather instruments: barometric pressure with a 3-hour trend, a rain nowcast field in words ("RAIN IN 2H"), and a forecast widget for the top row or bottom band, hourly or daily, with weather symbols in monochrome or natural colour. The forecast has its own source, separate from the rain band's. 0.6.3 — Rain band can read from Garmin, Open-Meteo (free, no account) or your own Home Assistant weather entity. Fixed a manual-scale graph drawing outside its chart. About 15 kB less memory in use. 0.6.1 — Projection Ring extends a ring with where its metric is heading. Rain band maps the hourly forecast onto the dial's clock positions. New Day Shape always-on mode draws the day's step profile as a polygon. 0.6.0 — Instrument look: Wire and Dashed ring geometries, a fourth ring at the bottom, numeric gauge labels, label tint, seven ring gradients, ten more colour themes and an Instrument preset. 0.5.x — Home Assistant freshness marking and temperature override, global temperature unit, 7-hour rain forecast widget, presets, Complication-backed fields, text fitting so no value overruns its column. 0.4.x — Grid bottom widgets, ring colours and gradients, flat/round ring ends, graph backgrounds, grouped settings submenus. 0.3.0 — Initial public release (beta).
