This is what an alert on WhatsApp looks like
The moment a temperature drifts out of range, the power cuts out or a door stays open too long, you get a message straight away. No dashboard to log into, no app to install. The message arrives where you are already looking.

This is how your HACCP records build themselves
Every reading is recorded. At the end of the month a complete, inspection-ready PDF report is waiting, with your temperature logging and your deviations log. No more rounds with a clipboard.

Within rangeThis is how the corrective action log works
When there is an alert, the WhatsApp bot asks what you did, with tappable options. Your answer goes into the HACCP report with your name and the time. This is exactly what the NVWA checks, and it is unique at this price.
Measure continuously, see the moment something goes wrong
A fridge swings all day long. Coolwatcher knows the normal rhythm and only raises an alarm when a limit is really crossed.
The tech, in plain language
Works without WiFi
The box uses NB IoT over the mobile network. No password, no outage when the router hiccups. It even works in the basement.
One measuring point per sensor
A thin 1 meter probe runs through the door seal, into your fridge or freezer. Measuring range roughly minus 55 to plus 125 degrees, accurate to half a degree.
Years on a single battery
The battery lasts for years and can be replaced. If the network drops for a moment, the box stores the readings locally and sends them later.
Nationwide coverage
NB IoT has coverage across the Netherlands, even in spots where regular mobile reception falls short.
