Frequently asked questions
Short, clear answers to what hospitality owners ask us.
Yes, digital records are fully allowed and often easier to prove than paper. The NVWA asks you to log and keep your temperatures consistently, not that they sit on paper. Coolwatcher records automatically and turns it into an inspection-ready PDF report every month.
An NVWA fine for missing records starts around 525 euro. Strikingly, missing records are the single most common reason for a fine, even when your temperatures were perfectly fine. With automatic, complete records you no longer run that risk.
No, Coolwatcher works without WiFi. The box sends its readings over NB IoT, a mobile network with coverage across the Netherlands that even works in the basement. There is no password to set up, and a flaky router never takes it down.
Installation takes about ten minutes and needs no technician or tools. You mount the box with magnets and slide the thin probes through the door seal. We ship everything by post, so you can get going right away.
Coolwatcher starts at 29 euro a month for one sensor with two measuring points, for example a fridge and a freezer. That includes your WhatsApp alerts, automatic HACCP records, batteries, replacement and support. Bigger businesses pick Plus at 49 euro or Pro at 89 euro a month, with more measuring points.
The moment a temperature goes out of range, the power cuts out or a door stays open too long, you get a message on WhatsApp straight away. That lets you step in before your stock is lost, day or night, weekday or weekend. Afterwards the bot asks what you did and records it in your HACCP report.
