EasyLog Case History


For a large number of businesses and applications, temperature monitoring and cold storage systems are an absolute necessity. Materials and products stored in the cold room can be of significant economic value, and it is vital that they remain at a sufficiently low temperature to avoid being rendered unusable. What often happens in reality?

  • Often temperatures are not monitored, or temperature reports are not presented at the right time.
  • Temperature deviations from established norms are often not reported.
  • Paper reports are not drafted, lost and difficult to analyze.
  • Updating centralized record sheets is difficult and time-consuming.
  • The quality of stored food can suffer due to a lack of easy-to-use monitoring solutions.
  • Employee training takes a long time.


To avoid product deterioration and for the health of consumers, it is essential to monitor and maintain the appropriate temperature.
Proper maintenance of product temperatures inhibits the growth of pathogens and reduces the risk of spoilage. In an industry where efficiency and profit margins are constantly scrutinized, it is important to ensure product quality.
In addition to the finished product, monitoring of the systems that create the ideal environment for storage is also very important. It is not uncommon to find obsolete and malfunctioning cold rooms, with components and control systems that are damaged or not fully functional.

The solution

Combining a data collection system with the control system allows you to constantly check your warehouse.
EasyLog is the ideal solution for collecting data and sending them to a centralized database.
EasyLog is able to collect data from temperature controllers and control systems equipped with ModBus protocol, it samples significant data and sends them remotely at regular intervals without needing an operator.
If critical thresholds are exceeded, there is the possibility of being notified by e-mail or Telegram message.

Benefits obtained

Our client had the following needs:

  1. Continuously and constantly monitoring chillers in the store of one of its end customers
  2. Knowing how the end customer uses his systems
  3. Monitoring the performance of compressors
  4. Integrating the system into the Industry 4.0 plan

The temperature monitoring period showed that most of systems worked well without particular problems, but some of them had been configured by the customer with too low intervention thresholds. Once the correct set-points were set, the end customer was able to save almost 6% of energy. In some systems that generated alarms, the notification arrived quickly and the problem was solved remotely without intervention on site.

In one case it was also shown that the efficiency of some systems is well below the average of similar products. This is probably due to the age of the devices. Even these elements emerging from the monitoring activity can be used later to continue the optimization and preventive maintenance process.
