Identify threshold values for honey harvest

There is almost no information on threshold values for the honey harvest, but placing the hive on a scale allows to gather information about possible honey harvest times, or to estimate the amount of food reserves. Collecting continuous data provide information on not only colony growth or food consumption, but also on swarming, variations in nectar or pollen availability, and absconding of colonies. It has to be mentioned, that weather conditions and the hive itself (various moisture level) have influence on the weighting-data (e.g. strong winds, snow, rain, …).
