Energy accounting
Cumulative kWh, tracked the way the utility bills you
Bronze polls each meter's cumulative energy registers and stores boundary readings in PostgreSQL. Set your billing-cycle start day (1 to 31, with short months handled correctly and DST-aware in your site time zone) and Bronze builds cycle totals that line up with the invoice.
- Meter Totals, Month-over-Month and Breaker Detail reports
- Blended-rate estimated cost per meter, breaker and cycle
- Missing readings are reported as unavailable, never extrapolated
- Branded landscape PDF reports with summary cards and page numbers
- CSV export for spreadsheets and accounting systems

Operations
Small footprint, serious plumbing
Bronze is deliberately simple on screen and deliberately robust underneath.
Isolated PostgreSQL
Bronze installs its own PostgreSQL 18 instance on a dedicated port, separate from anything else on the machine, or connects to a PostgreSQL you already manage.
Verified backups
Manual and weekly backups use pg_dump and are verified with pg_restore before they are reported as good. Every update takes a verified backup first.
Signed self-update
Updates are downloaded over HTTPS, verified by signed manifest and SHA-256, staged by a scheduled task, and rolled back automatically if the new service fails its health check.
Local accounts
Admin and user roles with a 15-character passphrase policy, rate-limited sign-in and server-side sessions. No directory dependency.
Light and dark appearance
Per-browser theme preference. Light by default for control rooms with bright lighting; dark for the rest of us.
Offline licensing
Activate online, or export a machine ID and import a signed license file for sites with no internet at all.
Honest scope
