Disconnects from meter for days at a time

[rehanson]

This integration is great when it's working. However, every couple of weeks or so, it will stop reading data from the EMU-2 and report 0 kWh for a few days. Eventually it will start reading the EMU-2 again, and all of the energy usage that was missed while disconnected will show up as a huge usage of energy in a single moment. It makes it difficult to read and analyze our power usage over time.
