Once upon a time I relied on ForecasWatch as the daily driver watchface on my beloved red Pebble Time. Recently, the free tier of the Weather Underground API on which the watchface relied was discontinued, making a huge portion of the watchface unusable.

The developer, RCY, is nowhere to be found in the Rebble era. I plan to continue using my Pebble(s) for years to come, so this is my attempt to revive this wonderful watchface—and this time it's open source!

A stable release is was made available on the Rebble store thanks to @joshua. Click here for the store page.

For more cutting-edge features, download the latest forecaswatch2.pbw release. On Android you can use Cx File Explorer to open this file through the Pebble app.

Prerequisites: Node.js and Docker Desktop

# Install JS dependencies
npm install

# Start the detached docker container
npm start

# Build within the container
npm run build

This will build the project inside a docker container containing the Pebble SDK. The .pbw output can be found in the build directory on the host machine.

You can also use npm run shell to access other Pebble CLI commands.

You can create a file src/pkjs/dev-config.js to set values for Clay keys (for convenience), e.g.

var darkSkyApiKey = 'abc123';
module.exports.darkSkyApiKey = darkSkyApiKey;
