I have been measuring my hives for weight and temperature for several years. I have found it very helpful to keep tabs on the progress of the hives through the summer, particularly in remote locations. Here are my current hives with the last seven days of data.

If you're interested in instrumenting your hives, all of my instruments are from Broodminder. They have been doing some amazing things with instrumentation, and they are doing great work for both commercial and hobbyist beekeepers.
