Built for the daily reality of the kitchen

Alerts and reports arrive on WhatsApp, right where you are already looking. No app to install, no dashboard to log into.

There is nothing to learn and nothing to open. Coolwatcher sends a message the moment something is off, and your monthly report lands in the same chat. Everyone in the kitchen knows WhatsApp, so everyone can keep an eye out.

Your temperature logging and deviation log run on their own. Every month an inspection-ready PDF report is waiting for you.

No more rounds with a clipboard and no lists that go missing during an inspection. Coolwatcher records every reading and builds your records automatically, saving well over 1,000 euro a year in manual work. Note: this covers your cold storage and the corrective log, not the core-temperature probing you do while cooking.

Coolwatcher uses NB IoT over the mobile network. No password, no outage when the router hiccups.

The box needs no WiFi or fixed internet connection and even works in the basement. NB IoT has coverage across the Netherlands, including spots where regular mobile reception falls short. If the network drops for a moment, the box stores the readings locally and sends them later.

Mount it with magnets, no drilling and no technician. We simply ship the box by post.

You hang the box on or beside your fridge with the magnets provided and slide the thin probe through the door seal. Within ten minutes Coolwatcher is measuring and you get your first message. No tools and no installer needed.

Instant alarm on a temperature deviation, a power failure or a door left open too long. One prevented incident pays for years of subscription.

A fridge that fails over the weekend can wipe out 2,000 to 8,000 euro of stock before anyone notices. Coolwatcher warns you straight away, in the middle of the night and on weekends too, so you can step in on time.

On an alarm the WhatsApp bot asks what you did, with tappable options. Your answer goes into your HACCP report with your name and the time.

Pick product discarded, thermostat adjusted or technician called, and Coolwatcher records it instantly. This is exactly what the NVWA checks and it is unique at this price. That way you show not only that you spotted a deviation, but also what you did about it.

Coolwatcher learns the normal rhythm of your fridge and warns you days ahead about a dirty condenser or a compressor on its way out.

Instead of only beeping once things have already gone wrong, you see a problem coming. That lets you plan maintenance calmly rather than calling an emergency technician in a panic. This feature is coming soon.

The hardware stays with Coolwatcher. Batteries, replacement and support are part of your subscription, with no upfront investment.

You pay a fixed amount each month and nothing unexpected on top. If something breaks, we replace it. Cancel monthly, so you are never locked in.

Your data sits on European servers and a data processing agreement comes as standard. An accredited ISO 17025 calibration certificate is available on request.

Your data is safe and traceable, exactly as an inspector or accountant wants to see it. If you want demonstrably calibrated readings, you add a calibration certificate to ISO 17025 per measuring point. That makes your records not just complete but watertight.
