I don't even need to stand by the window.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.
Something like this works perfectly fine for the backyard hives (and can just sit right on your computer table - so you can read BS and look at your hive sensor feeds at once):
The thing about "loss prevention" - you will simply see how the temp in a hive will drop abruptly - you will go and check - you will see the dead bees.
These sensors are largely "reactive" data readers; not "proactive" and can not look ahead of time.
It is also not a good idea to react every time to temp/humidity changes - you just bother bees for not reason most of the time - most of the time those changes are just a norm.
Ask me how I know.
