So I am trying some new things this year to prevent the loss I have occurred over the last cold winters here near the Great Lakes. Created a quilt box and hives wrapped in 2 inch foam insulation.
But the newest addition is a Govee bluetooth temp and hygrometer monitor in each hive. Now I can stand at the back window of the house and get a readout on the temp and humidity levels inside the hive.
So far it has been working great. I even have alarms set for low/high temp and humidity levels and my phone will get an alert when I sync up if something is wrong.
