Cold weather. The temperature is about 12C. Bees don't fly. Ventilation is slightly open in all hives. Most of the bees are inside the "streets" ( between frames). Above the frames there are individual bees. We made control of 2 bee families using Apivox Smart Monitor - families E1 and E3.
In E1, the bees are calm and busy with in-hive works. When trying to see signals in the Monitoring mode, I had to increase the gain so that a yellow warning icon appeared on the screen. This suggests that diagnostics can sometimes be erroneous due to a very weak signal, but in principle it is still possible to work with the device. In the E1 family, the upper ventilation window is open, while it is quite cold outside. Therefore, we see an increased level of emergency heating, although it is not described in the diagnostics, since the increase is not significant.
In E3, the bees are much calmer and the diagnostics indicate the absence of significant works. It's right. The bees are very quiet. The results of brood control in this family in which we destroyed the rest of sealed brood and slightly opened the upper ventilation window indicate that there is no open brood at all. The picture absolutely clear and unequivocal.
