How TEMPASCAN works: automatic temperature monitoring and HACCP documentation for the hotel and catering industry<\/h1>\n

In a nutshell:<\/strong> 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<\/a> and can be accessed at any time for 10 years. <\/p>\n

The problem: manual temperature checks take time and are prone to errors<\/h2>\n

In hotels, restaurants, catering businesses and food production, regular temperature checks of refrigerators, freezers and cold stores are a must. HACCP regulations require complete documentation, but in practice this often means handwritten lists, forgotten inspection rounds and, in the worst case, loss of goods that are only noticed when it is too late. <\/p>\n

TEMPASCAN solves this problem with a fully automatic system that works without manual intervention.<\/p>\n

\n

How TEMPASCAN works: the technical process in five steps<\/h2>\n

Step 1: Wireless Bluetooth sensors measure temperature and humidity<\/h3>\n

Each cooling appliance has its own wireless Bluetooth sensor. This is installed directly in or on the cooling area, i.e. in the refrigerator, freezer, cold store or preparation area. No wiring is required, nor is any software installation on the cooling appliance. <\/p>\n

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. <\/p>\n

Step 2: The gateway receives the data and forwards it<\/h3>\n

A central gateway in the plant receives the measured values from all connected sensors via Bluetooth. The gateway is the technical bridge between the physical cooling points and the digital cloud platform. <\/p>\n

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. <\/p>\n

Step 3: The TEMPASCAN Cloud stores all measured values securely<\/h3>\n

After transmission through the gateway, the data ends up in the TEMPASCAN Cloud. All temperature and humidity values are stored there for 10 years<\/strong>. The software comes from Berlin and is developed and operated by Claysoft GmbH. It is hosted exclusively on servers in Germany, fully GDPR-compliant. <\/p>\n

This creates seamless digital documentation that replaces handwritten lists and can be retrieved at any time during internal audits and official inspections.<\/p>\n

Step 4: The web app makes all data visible and analyzable<\/h3>\n

The stored measured values can be accessed via the TEMPASCAN web app on a PC, tablet or smartphone. Current temperatures, historical curves and deviations can be checked at a glance. <\/p>\n

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

Step 5: An alarm is automatically triggered if the limit value is exceeded<\/h3>\n

As soon as a sensor measures a value outside the defined range, the system automatically triggers a notification by email, SMS, WhatsApp or push message. The alarm reaches the responsible team in real time, without manual intermediate checks. <\/p>\n

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