IoT Solutions Group (IoTSG) provides COSIE, an API-connected evidence layer that helps housing and estates teams manage risk with defensible in-home data, at scale across complex portfolios. Battery-powered IoT sensors work without resident Wi-Fi or mains power. Recovery-aware analytics reduce false positives and wasted visits, while exception-led alerts and automated reports support audit readiness. COSIE starts with damp and mould risk, and expands into retrofit performance evidence and water safety compliance for Legionella control. Insights can feed existing BAU workflows through dashboards, reports and APIs. Privacy-first by design, COSIE uses no cameras or microphones, and is delivered with operational support.

COSIE homes Pro proves real-world retrofit performance, continuously, in occupied homes. COSIE homes Pro is a SMETER-compliant module within the COSIE platform that replaces point-in-time assumptions with always-on in-home evidence.

What it measures (and why it matters):

• Heat loss, quantified: Calculates Heat Transfer Coefficient (W/K) to show how much heat the dwelling is actually losing, before and after retrofit.
• Moisture risk, tracked: Monitors dewpoint change to flag ventilation/condensation conditions that drive damp and mould risk, especially post-retrofit.
• What it enables:
• Evidence PAS2030/PAS2035 compliance with time-stamped, defensible performance data
• Validate retrofit outcomes across programmes, not just at survey milestones
• Reduce post-retrofit damp & mould risk by detecting adverse trends early and targeting interventions

Delivered as a fully managed service: Dashboards, human-readable reports, and API integration so evidence flows into BAU systems and processes, scaling across stock and risk areas without becoming retrofit-only tooling.
