The clip-on revolution
Why we still pay people to hold thermometers.
Every month, housing officers and compliance contractors drive to a site to do one thing: hold a thermometer under a tap.
They're checking a sentinel point for HSG274. If the hot water reaches 50°C within a minute, they tick a box, log it in a spreadsheet, and drive to the next one.
It's an administrative answer to a physical problem.
And it costs the sector millions a year in fuel and engineer hours — to capture a single number, once a month, that's already out of date by the time the van pulls away.
A snapshot can't see Friday.
A reading from last Tuesday doesn't tell you the boiler failed on Friday. It doesn't tell you an uninsulated pipe is bleeding heat into the cold main right now, turning a dead-leg into somewhere legionella is happy to live.
The risk doesn't keep to the inspection calendar. The monitoring shouldn't either.
Clip it on. Walk away.
The fix is non-invasive and continuous. A clip-on LoRaWAN temperature sensor fixes to the outside of the copper — no plumber, no cutting in, no breaking the seal of the system. It streams the pipe temperature back to the dashboard every few minutes, around the clock.
Now the building checks itself. The thermometer-under-the-tap round — the one that filled a calendar and a tank of diesel — simply stops existing.
The point.
Stop paying people to hold thermometers.
Let them fix the problems the data finds instead.
