Temperature history shows how a measured temperature develops over time.
VAKTEN does not only display the current measurement. The history presents the measurement series over a selected period and places it in the context of the selected rule.
Periods in temperature history
Different periods are available for evaluation:
- Today: shows the measurements of the current day at high temporal resolution.
- 7 days: shows the temperature development over the previous seven days.
- 30 days: provides a longer-term view of changes and recurring deviations.
- Date: allows a single historical day to be selected, even when it is more than 30 days in the past.
This makes it possible to assess the current development as well as review a specific day in the history.
Minimum, average and maximum
In addition to the temperature curve, VAKTEN displays the main values for the selected period: minimum, average and maximum.
Individual points on the curve can be inspected using a mouse pointer or touch. Measurement coverage and visible data gaps help indicate how completely the selected period was recorded.
The rule gives the measurement meaning
The technical temperature measurement belongs to the signal. Its operational meaning, however, is created in the context of a rule.
The same temperature source can therefore be used in different contexts. One rule may evaluate room temperature, while another application monitors a temperature limit in a refrigerated area.
The signal measures. The rule interprets.
Measurements become concrete tasks
A temperature measurement can have different meanings depending on the monitored area and the rule. The same technical foundation can therefore be used for very different applications.
Room temperature monitoring
A room can be monitored separately. If, for example, the temperature exceeds 25 °C, VAKTEN can trigger a rule and send an email asking for the heating to be switched off.
A suitable rule could be: Send an email when the temperature exceeds 25 °C.
The user or another selected recipient then receives a notification that the temperature limit has been exceeded and that action is required.
Cold rooms and temperature-controlled areas
In a cold room or another temperature-controlled area, such as frozen storage, VAKTEN can detect when the temperature moves outside the intended range.
A rule can then indicate that the room should be closed, the refrigeration system checked or a responsible person informed.
Evaluating a temperature sensor alone may already be sufficient. When combined with door sensors, it is also possible to see whether an open door may have contributed to a temperature deviation. Temperature history and door state can therefore be viewed together.
A rule can also be assigned to another recipient. For example, a warehouse employee or another responsible person can be informed by VAKTEN when a need for action has been detected.
Temperature history can therefore be used to monitor cold chains over the long term, document deviations transparently and evaluate developments over extended periods.
Monitoring refrigerators and medicine refrigerators
Sensitive goods, medicines and other temperature-sensitive contents require particular attention. VAKTEN can consider both the temperature and additional states such as whether a door is open or closed.
Typical scenarios include:
- Medical practice: The operator receives an email notification if the temperature of a medicine refrigerator leaves the defined range.
- Hospital: Different refrigerators or storage areas can be monitored separately and assigned to different responsible persons.
- Pharmacy or laboratory: Temperature deviations can be documented and, where required, reported to defined recipients.
- Food or refrigerated areas: Temperature and door state can be considered together to help assess deviations more quickly.
The combination of temperature measurement, rules, history and additional sensors turns a simple measurement series into a practical operational use case.
