Give your clients continuous legionella compliance — not clipboard checks.

We build bespoke IoT temperature sensors and a white-label dashboard so your water hygiene business can sell 24/7 monitoring. ACoP L8 and HSG274 compliant out of the box.

Your engineers are still doing monthly sentinel checks with a thermometer and a clipboard.

Every missed reading is a compliance gap. Every gap is a liability. Your competitors are already offering remote monitoring — reducing site visits while charging recurring fees. Building this in-house means hiring hardware engineers, firmware developers, and cloud architects you don't have. We do the entire build so you can focus on selling and servicing.

The problem

Monthly and weekly temperature checks at sentinel points are time-consuming, error-prone, and create compliance gaps between visits. Manual records don't survive scrutiny in an incident investigation.

What we build

Wireless temperature sensors at every sentinel point, streaming to a dashboard your clients can access. Automated alerts when temperatures drift outside safe ranges. Reports generated on demand — not manually compiled.

Outcomes

  • Continuous ACoP L8 / HSG274 compliance data
  • Automated alerts — hot water <50°C or cold >20°C
  • Audit-ready PDF reports in one click
  • White-labelled dashboard for your brand
  • Fewer site visits, higher margin per client

US — ASHRAE 188 / CMS Healthcare

The problem

CMS-certified healthcare facilities must comply with ASHRAE 188 water management programs. After a Legionella outbreak, litigation costs dwarf the monitoring investment. Manual checks don't provide defensible evidence.

What we build

Same sensor architecture, configured for ASHRAE 188 requirements. Continuous temperature monitoring with complete audit trails for CMS survey readiness.

Outcomes

  • ASHRAE 188 water management program support
  • Defensible digital records for CMS surveys
  • Litigation risk reduction through continuous monitoring
  • Dashboard designed for hospital facility teams
EU — Drinking Water Directive 2020/2184

The problem

Germany's Trinkwasserverordnung requires hot water ≥55°C and cold <25°C at all times. The EU Drinking Water Directive mandates risk assessments for priority premises — hospitals, care homes, hotels. Manual checks can't scale across multi-site operations.

What we build

Localised compliance dashboards with regulation-specific thresholds. Same sensor hardware, adapted reporting for each national framework.

Outcomes

  • Trinkwasserverordnung continuous compliance (DE)
  • Priority premises monitoring for Directive 2020/2184
  • Multi-site portfolio dashboard
  • Automated alerts per national threshold standards

We build the full product. You sell it.

Temperature Sensors

Custom PCB design optimised for water hygiene monitoring. Battery-powered, waterproof, designed for pipe-mount or immersion installation.

  • ±0.5°C accuracy across 0–100°C range
  • Battery life 3–5 years (configurable)
  • IP67 rated for wet environments
  • BLE / LoRa / NB-IoT connectivity options

Device Firmware

Reliable embedded software that handles sensing, transmission, and OTA updates without failing silently in the field.

  • Configurable reading intervals (1 min — 24 hrs)
  • Low-power sleep scheduling
  • OTA firmware updates
  • Edge alerting for offline operation

Compliance Dashboard

Client-facing dashboard powered by Paqett. Real-time readings, historical trends, automated compliance reports.

  • Live temperature readings per sentinel point
  • ACoP L8 / HSG274 compliant report generation
  • Alert configuration (email, SMS, webhook)
  • White-label ready — your brand, your domain

Pilot & Rollout Support

We don't hand over a prototype and disappear. We support through pilot, rollout, and ongoing iteration.

  • 3–5 site pilot programme
  • Installer documentation & training
  • Ongoing platform hosting & maintenance
  • Hardware iteration as you scale
