Clipboard log sheets prove nothing. A live audit trail proves everything.
“L8 compliance, statutory water safety”
Legionella is the standard where the regime matters as much as the threshold. ACOP L8 carries near-statutory weight; HSG274 sets the temperatures; HTM 04-01 adds NHS-specific rules. Continuous monitoring replaces the monthly clipboard with a defensible, second-by-second record per outlet.
Three capabilities, one feed.
Per-outlet temperature
Hot pipe, cold pipe, hot return, calorifier. Sustained < 50°C hot or > 20°C cold auto-raises a corrective-action ticket.
Automatic flush trigger
Stagnant outlets identified by flow events. Integration with automated flush valves where installed — schedule generated, not remembered.
Augmented-care thresholds
NHS HTM 04-01 augmented-care rooms have tighter rules (hot ≥ 55°C). The system applies the right rulebook to the right outlet automatically.
Sustained temperature dropout flagged in minutes, not at the next month-end log review. The Wavetrend / Strega tier of probes feed the same loop.
It doesn’t stop at the screen.
The reading is checked against the rulebook on an orchestration engine. When it’s out of band the job is created, sent to the right person and chased until it’s signed off — and every step is logged. Here’s a real flow for legionella.

The log writes itself.
The clipboard becomes a document that writes itself. Every outlet's hot, cold and return temperatures are logged continuously, then rolled up on the schedule you need — a weekly digest of what moved, and the full monthly HSG274 / ACOP L8 monitoring log. It lands in the responsible person's inbox ready to read, sign off and file. When the HSE asks, the evidence is already written: pass or fail, per outlet, per month, with the reading and the date behind every cell.
The audit trail it builds.
One sensor stream. Multiple rulebooks. Each row links to the full entry in the Standards matrix.
