See evolution over time
Monitoring hives is about collecting data and presenting it so that you can see the evolution over time. How you understand and interpret the data depends very much on local conditions and on you.
Indications and trends
They take some time to gain insight and learn to interpret the information. Data and status need not always be exact values, but rather show indications and trends of change. The most important thing is to get an impression of the normal situation in the hives, deviations from this indicate changes that may require action. But not necessarily. By monitoring the hives, you can take action if necessary and otherwise leave the bees alone. You will save yourself work and the bees will remain happier and produce more honey, if you do not open your hives unnecessarily.
