A low-power sensor on each valve reads the moment it changes state, and the dashboard shows every valve across the estate, with no change to the valves or the plumbing.
Automatic and smart water shut-off valves do one job well: when a leak or abnormal flow is found, they close the supply and stop the water. The gap is not the valve — it is knowing, across a whole portfolio, which valves have closed, where and when. On an estate of hundreds of units that signal usually never leaves the building.
We close that gap with a retrofit sensor fitted to the valve you already have. The valve closing is a clear change of state, and the sensor reads that state directly. Because it reads the physical state rather than the valve's own network, it works the same whether a unit talks ZigBee, LoRaWAN or nothing at all — so a mixed estate of different makes lands on one consistent feed.
The instant a valve trips, that event is pushed as a real-time alert and the valve's status updates on a live dashboard. Routing is shaped around how the estate is run — by site, region, team, time of day and out-of-hours cover — and escalated if it is not acknowledged, so a closed valve reaches a person rather than sitting unseen until a tenant calls.
It is built for retrofit and for scale. Sensors are UKCA marked, low-cost to install with no rewiring, and designed for multi-year battery life, so maintenance overhead does not kill a rollout before it reaches the whole estate. The same architecture runs a single building pilot or thousands of valves across a national portfolio, with the audit trail intact throughout.
This is a visibility and alerting layer that strengthens the shut-off regime you already have. It complements your valves, plumbing design and insurance obligations on a best-endeavours basis; it does not replace them, and it does not control the valve.
