You can see the current weight, the weight change in the last 24 hours, the last 7 days, the last 30 days (in the web application), and the weight curve over the whole season with the white curve. The red line allows you to set the reference weight when you start the measurement on the season as a comparison (web application).
The number of active bees is calculated from the morning weight loss when the bees leave the hive, based on the weight of one bee, 0.1 gram.
Weight: shows current weight and daily, weekly or monthly increases or decreases
The weight is also sensitive to weather (frost, dew, rain, direct sunlight). Then the weight can fluctuate so that it is more the long-term trends that you have to look at. However, it is quite sufficient for beekeeping needs.
