Your logbook
writes itself.
Wireless sensors, NFC flushing tags and one app keep your legionella logbook up to date automatically. Water temperatures are monitored day and night, every tap is tagged when it is flushed, the sensor shows for each flushing round whether hot water came from the installation, and the report for the inspector is ready with one click.

Example: this is how your logbook keeps track, day and night.
- Made for campsites, hotels, schools, sports halls, care homes and more
- Installed yourself in 30 minutes, no installer needed
- Works alongside your water safety plan and your adviser
In the box
A box on your counter, not an IT project
You order a kit that is prepared for your site, together with the subscription to the app. Everything is included and you mount it yourself in half an hour, without an installer.

Receiver (gateway)
plugs in at reception and forwards everything; kit L contains two
Wireless sensors
one per hot water installation, with a red probe for the hot pipe and a white one for the cold pipe
NFC flushing tags
one at every tap that is flushed, in one bag per building
Sleeves and mounting material
insulation sleeves, clamps or cable ties, mounting paste, a screwdriver and the installation card for your site
How it works
Sorted in half an hour
No installer, no waiting time, no quotation process. You open the box and get started.
Stick and clip
Clip the wireless sensors onto your hot and cold water pipes and stick a tag at every tap. Everything you need is in the box.
Tap and measure
The sensors measure day and night and alert you to deviations. Your staff member records each flush with one tap.
The logbook writes itself
All measurements and flushing rounds go into your logbook automatically. For the inspector you export it as a pdf with one click.
Verified flushing evidence
A tick is a claim. A temperature jump is evidence.
Your staff member holds the phone against the tag and lets the tap run until the timer reaches zero. The sensor on the hot pipe from the water heater sees for each flushing round whether hot water came from the installation, hot enough for that installation's threshold. So your logbook holds a measurement, not a promise. Exactly what an inspector wants to see.
Made for your kind of site
Every tap in the round at the right moment.
The planning per room knows when your site is empty: the winter closure, the school holidays, the summer break or an empty room. The taps then come onto the list by themselves.
Configure your kitWinter closure and reopening
One button takes closed buildings out of the round; when you reopen, the extra round is ready.
School holidays
The holidays of your region are ready as a period: the classrooms and changing rooms then join the round every week.
Summer break and a bag per changing room
Closed with the water on or drained, and every changing room its own tags.
Rooms and occupancy
An occupied room counts as flow; an empty room comes onto the list after a few days.
Resident rooms per ward
After a departure the room stands empty and belongs on the flushing list, per ward.
Christmas and summer shutdown
Two weeks with nobody in the building: the pantries and showers join the round those weeks.
Prices
Our prices are simply on the website
A campsite, park, marina, school, sports hall or office chooses by the number of buildings with their own hot water supply; a hotel, group accommodation or care home by the number of rooms. All prices excluding VAT; for business customers in the EU the VAT is reverse-charged.
Choose by the number of buildings with their own hot water supply. Buying: the kit once, then the subscription.

More temperatures, same evidence
Coming soonMonitor other temperatures on your site with the same sensors and the same evidential value.
More obligations, one logbook
Coming soonWhat you record for legionella now, soon for other checks as well, in the same logbook.
