Refrigerator Temperature Monitoring System

Use Casesvg>

Brief: I want a refrigerator temperature monitoring system.

In the hospitality sector, it’s crucially important that the temperature of refrigerators, freezers and cold rooms are continuously monitored and recorded. Manually recording this data is extremely painstaking and time-consuming. However, with Loxone you can commission an automated refrigerator temperature monitoring system – allowing exact temperature recording, but also immediate notification should the temperature fall below or exceed a pre-defined range.

Solution: Using Loxone to create a refrigerator temperature monitoring system.

With Loxone, there are many ways of collecting and storing data. In this Use Case, the temperature of a cold storage room is being measured with the Room Comfort Sensor Tree. It has a measuring range of -40°C to 120°C, making it the perfect tool for precise temperature recording of a cold rooms, refrigerators or freezers.

The recorded values will then be displayed within the Loxone App – so they can be checked at any time. By using the Logger function on the Minisever, these values can also be stored on external data servers or on FTP (File Transfer Protocol).

Particularly in the commercial sector, it may be necessary to log temperature undershoot or overshoot. In our example, this was solved using the function block “Min Max Since Reset”. The maximum and minimum temperatures witnessed for each day are captured with a daily impulse at 23:59:39. At the same time, these daily minimum and maximum values are displayed in the Loxone App using the “Tracker” logging feature.

If the temperature deviates for more than 3 minutes, then a phone call will be made via the Loxone Caller Service to inform the relevant people.
