One plugin. Multiple AI providers. Unlimited possibilities.

Universal AI connects Pebble applications to your choice of AI service through a single, standardized interface. Instead of requiring separate integrations for each AI provider, applications can communicate with your preferred AI using one plugin.

Supported AI providers:
- Google Gemini
- OpenAI (ChatGPT models)
- Anthropic Claude
- xAI Grok
- OpenRouter
- DeepSeek
- Muse

Features
- Choose your AI: Configure your preferred provider and model.
- Bring your own API key: Each provider has independent, securely stored credentials.
- Full responses: Returns the complete AI-generated response to the requesting application, rather than just a notification or delivery confirmation.
- Conversation memory: Maintains conversation context across multiple messages.
- Universal compatibility: Provides a standardized API for Pebble developers.
- Privacy controls: Manage and clear locally stored conversation history.

How it works
Install Universal AI on your Pebble phone app, select an AI provider, enter your API key, and choose a model.
Compatible Pebble applications can then send requests through Universal AI and receive responses directly. Each application decides whether to display, summarize, speak, or otherwise use the response.
Universal AI handles communication with the AI provider. The application handles the user experience.

Important: An API key from your chosen provider is required. API usage may incur charges. Subscriptions such as ChatGPT Plus, Claude Pro, or Google AI Pro do not necessarily include API access.

For developers
Universal AI supports Pebble's standard "send_to_agent" action, "agent/chats" and "agent/configured" sources, plus an extended request/response API with conversation IDs, request tracking, and response retrieval.

**Reliable and configurable**
Weather+ includes data validation, source diagnostics, manual refresh, and worldwide provider testing. Advanced diagnostics are hidden by default and can be enabled when troubleshooting. Diagnostic reports can be saved to your phone.

**Requirements**
Weather+ supplies weather data to compatible Pebble apps and watchfaces; it is not a standalone weather display. Some features require internet permissions, and OpenWeather requires your own One Call 3.0 API key and subscription.

**Support development**
Weather+ is independently developed and maintained. If you find it useful, you can support continued development at: https://ko-fi.com/ericmccormick

**Pebble Weather Plugin Compatibility**

Weather+ can also use the official Pebble Weather plugin as a weather data source, providing a convenient option for users who already have it configured.
However, selecting the Pebble Weather plugin instead of Weather+'s direct weather providers may limit the weather information available, including the number of supported data fields and how far into the future forecasts extend.
For the most comprehensive weather data and longest available forecast range, we recommend using Weather+'s built-in providers, such as Open-Meteo, MET Norway, NWS, or OpenWeather.

Your next 48 hours, visualized. Built specifically to push the limits of the Pebble Time 2's high-resolution display. Whether you're coordinating a Scout campout, dialing in your morning commute, or tracking incoming storms, Timeline WX delivers precision meteorological data at a glance, with no squinting required.

Instead of static daily summaries, smoothly scroll through a continuous 48-hour timeline. We have stripped away cluttered text and replaced it with clean, data-driven visual indicators so you can assess your environment instantly.

THE ARCHITECTURE
Instant Offline Resume: Your timeline is cached directly to the watch's flash memory. Launch the app and see your forecast instantly, even if your phone is disconnected.

Auto-Pruning Timeline: The watch continuously syncs with the hardware clock to automatically hide past hours, ensuring your scroll always starts exactly at "Now."

Ultra-Battery Optimized: Completely rewritten to run natively on the Pebble OS background clock, reducing battery drain by up to 98 percent.

FREEDOM OF WEATHER DATA (NO API KEY REQUIRED)
You are no longer locked into a single weather provider. Timeline WX now features an internal translation engine, allowing you to seamlessly swap between four world-class meteorological APIs directly from the settings menu. Choose the provider that works best for your specific geographic location:

Open-Meteo is the default option. It is great for global use and requires no API key, though it relies on broader aggregated models.

The National Weather Service (NWS) is highly accurate for US locations using regional grid data, but it is restricted to the US and lacks UV Index data.

Yr.no / Met.no provides world-class precision MEPS modeling for European and Nordic locations, but also lacks UV Index data.

OpenWeather OneCall 3.0 provides complete global data including the UV Index, but requires registering for a personal API key.

(Note: If a selected provider does not support UV data, the UV safety bar will gracefully hide itself rather than displaying false information).

SMART ENVIRONMENTAL WARNINGS
Stop reading numbers and start seeing conditions. Timeline WX actively processes combinations of temperature, wind speed, UV, and humidity to color-code threats.

Dynamic Hazard Badges: A colored badge sits directly behind the weather icon based on a custom algorithm. Yellow means uncomfortable (muggy, hot, or cold). Orange means a warning (high winds, severe UV, or approaching storms). Red means dangerous (extreme temperatures or severe weather).

Temperature Alerts: Values turn Red when blistering hot (90F or higher) and Blue when freezing (32F and below).

High Wind Warnings: Wind speeds turn Orange when gusts exceed 20 MPH, which is perfect for knowing when to tie down the tent fly.

Midnight Dividers: High-contrast double lines and red timestamps explicitly mark when the forecast crosses into a new day.

INTUITIVE RAIN AND UV TRACKING
Rain Pie Charts: Ditch the confusing percentage text. Custom blue pie charts show you exactly how likely it is to rain, hour-by-hour.

UV Safety Bar: A dynamic, color-coded safety bar runs down the right edge of the screen, letting you know exactly when you need sunscreen on a Green to Purple scale.

CORE FEATURES AND CUSTOMIZATION
On-Wrist Settings Menu: Long-press the Select button to toggle Dark Mode or swap units directly from your watch, and changes instantly sync back to your phone.

Decoupled Measurements: Mix and match your preferred units. Supports Fahrenheit, Celsius, Kelvin, and Rankine for temperature, alongside MPH, KPH, m/s, and Knots for wind.

Dark Mode: Invert the UI for a high-contrast, low-light optimized viewing experience.

Live Telemetry Banner: The bottom banner dynamically displays live countdowns to the next refresh, active server connections, and current location.

Precision Location: Choose between automatic Phone GPS or a manual Zip Code, with background refresh intervals adjustable from 15 minutes to 2 hours.

SETUP INSTRUCTIONS
Install the app, and you are immediately ready to go using Open-Meteo as the default provider!

If you prefer to use OpenWeather, you will need to supply your own key to keep the app free. Sign up for a free account at OpenWeatherMap.org. Subscribe to the "One Call 3.0" API and generate a free API Key. Set your daily call limit to 1000 to ensure it remains completely free. Paste the key into the Timeline WX settings page, switch the provider dropdown to OpenWeather, and save.
