How TEMPASCAN works: automatic temperature monitoring and HACCP documentation for the hotel and catering industry

In a nutshell: TEMPASCAN monitors cooling appliances around the clock using wireless Bluetooth sensors, automatically transmits the measurement data to the cloud and notifies the team by email, text message or WhatsApp as soon as a limit value is exceeded. The sensors are manufactured in Finland, the software is developed by Claysoft GmbH in Berlin, and all temperature data is stored on German servers in compliance with the GDPR and can be accessed at any time for 10 years.

The problem: manual temperature checks take time and are prone to errors

In hotels, restaurants, catering businesses, and food production facilities, regularly checking the temperature of refrigerators, freezers, and cold storage rooms is mandatory. HACCP requirements mandate complete documentation, but in practice this often means handwritten lists, missed inspection rounds, and—in the worst case—loss of goods that isn’t noticed until it’s too late.

TEMPASCAN solves this problem with a fully automatic system that works without manual intervention.

How TEMPASCAN works: the technical process in five steps

Step 1: Wireless Bluetooth sensors measure temperature and humidity

Each cooling appliance receives its own wireless Bluetooth sensor. This is installed directly in or on the cooling area, i.e., in the refrigerator, freezer, cold storage room, or preparation area. No wiring is necessary, nor is any software installation required on the cooling appliance.

The sensors are manufactured in Finland, one of the world’s leading locations for precision electronics and sensor technology. This means robust, industrially proven hardware that is designed for continuous use under demanding conditions. The battery lasts for approximately two to three years and can then be easily replaced with a standard button battery.

Step 2: The gateway receives the data and forwards it to

A central gateway at the facility receives the measurement data from all connected sensors via Bluetooth. The gateway serves as the technical bridge between the physical cooling points and the digital cloud platform.

Three options are available for the Internet connection: WLAN, LAN or a mobile SIM card. This means that TEMPASCAN also works in locations without a stable landline network, for example in catering businesses, at festival stands or in food trucks.

Step 3: The TEMPASCAN Cloud securely stores all measurement values

After being transmitted via the gateway, the data is stored in the TEMPASCAN Cloud. All temperature and humidity readings are stored there for 10 years. The software is based in Berlin and is developed and operated by Claysoft GmbH. Hosting takes place exclusively on servers in Germany and is fully GDPR-compliant.

This creates seamless digital documentation that replaces handwritten lists and can be retrieved at any time during internal audits and official inspections.

Step 4: The web app makes all data visible and analyzable

The stored measurement values can be accessed via the TEMPASCAN web app using a PC, tablet, or smartphone. Current temperatures, historical trends, and deviations can be viewed at a glance.

This is particularly valuable for companies with several sites: all refrigeration points can be monitored centrally without anyone having to be on site.

Step 5: An alarm is automatically triggered when a threshold is exceeded

As soon as a sensor measures a value outside the defined range, the system automatically sends a notification via email, SMS, WhatsApp, or push notification. The alarm reaches the responsible team in real time, without the need for manual intervention.

Typical triggers are open refrigerator doors, power failures or technical defects. Early notifications reduce loss of goods and protect the cold chain.
