About the profile data
The Powercalc profile library is a public, community-maintained catalog of measured device power data. Powercalc uses these profiles to estimate consumption for devices that do not report their own power use.
Who maintains it
Community members measure devices and submit their results publicly. Powercalc maintainers review and integrate those contributions, while this site makes the library easier to search and inspect.
Meet the contributorsData provenance
The source of truth is the public profile_library directory. Each model has a model.json file describing its identity, measurement method and calculation strategy, with measured CSV data where the strategy needs it.
Refresh frequency
In production, the site refreshes its prerendered library and analytics content every hour. Accepted changes become visible after the source data and public API have updated and the next refresh has completed.
Analytics and privacy
Powercalc analytics is optional, aggregated and disabled by default. It can report counts such as profile, device-type and strategy usage, but not device names, Home Assistant credentials, power readings, IP addresses or precise locations.
API and source
The viewer reads the public Powercalc API. The complete library is also available as raw JSON, and both the Powercalc project and this viewer are developed in public.
