scripts/bench/plugmeter.py prints watts/mA/V/kWh as CSV from the Tuya plug on the LAN
(default) or from Home Assistant on demo-hp's guest. 10-minute side by side and a
3-minute control in documentation/audits/plugmeter-2026-10-13/: Home Assistant alone
did not move for 3 minutes, so the LAN reader is the measurement source.
No key, device id or token in the repo; secrets scan 0 hits with a positive control.
