The Android app never connects to MongoDB directly and never contains a MongoDB URI. This service stores completed daily totals in daily_consumption and each completed charge, including its SOC/power curve and price, in charging_sessions.

Run

Copy .env.example to .env and fill in the MongoDB Atlas URI and a random API token.
Export the variables (Node does not load .env automatically), then run npm install and npm start.

Build the Android app with the public HTTPS service address and the same token:

CONSUMPTION_API_URL=https://your-api.example.com \
CONSUMPTION_API_TOKEN=your-random-token \
./gradlew assembleUnstableRelease

If either Android build variable is missing, cloud sync is disabled and local consumption tracking continues unchanged. The car retries locally queued charging sessions every five minutes. Daily consumption is uploaded once after the day closes; missed days are retried in order.

The future mobile client can read authenticated history from:

GET /v1/consumption/:installationId
GET /v1/charging-sessions/:installationId
