Information on getting to and reading the energy monitoring tool in HS4.
Use the Energy page in HS4 to keep tabs on the energy consumption in your home. Any Z-Wave device which reports energy usage will feed data to this database, as can devices from compatible plugins.
The Energy page can be accessed from Tools > Energy
When devices have reported energy consumption data, it will automatically be graphed out and the table filled out at the bottom. The axes are labeled for all graph types, and all values in the middle of the table are KW as reported form devices while those on the right are energy costs based on the cost of energy in your area.
