Temperature monitoring and HACCP for the daily reality of the kitchen

Alerts and reports arrive on WhatsApp and by email, right where you are already looking. No app to install and no login required.

There is nothing to learn and nothing to open. Coolwatcher sends a message over WhatsApp and email the moment something is off, and your monthly report lands in the same chat and inbox. Everyone in the kitchen knows WhatsApp, so everyone can keep an eye out. And if you want more overview, you log in to your dashboard, though it is never required.

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.

Stick it on with the 3M tape already on the sensor, no drilling and no technician. We simply ship the box by post.

You stick the box on or beside your fridge with the 3M tape already on the sensor 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.

A WhatsApp is easy to sleep through. On a power outage or a fridge running away the sensor calls you, right until you pick up. One prevented incident pays for years of subscription.

A commercial fridge should be serviced twice a year, and still one regularly fails, usually at night or over the weekend when nobody is there. A full fridge or freezer easily holds 2,000 to 5,000 euro of stock, and it spoils within a few hours. Normal alerts come over WhatsApp, but on a critical failure such as a power outage Coolwatcher switches to an automatic phone call, and calls the next contact if you do not answer. You only have to prevent one such incident for Coolwatcher to pay for itself for years.

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.

No login required, but if you want more: your dashboard shows every measuring point live, the history in graphs, and lets you download your HACCP reports.

WhatsApp and email keep you posted without any hassle. When you do want the full picture, you log in to your Coolwatcher dashboard: live temperatures of all your fridges and freezers, temperature graphs over time, your complete alarm log, and every monthly report to download. Ideal for multiple locations or a strict audit.
