No display comes with the unit—the real-time data is viewed via computer or smartphone. Data can be downloaded to Excel or other data management software for further analysis.
One unique twist on Wattvision’s approach to energy monitoring is the ability to “share and compare” your use with the electricity consumption of other Wattvision users. This has the opportunity to encourage engagement about energy consumption. The Wattvision unit is available on the company’s website.
Although it falls outside of the scope of single-residence monitoring, one group of products in particular is worth mentioning—The E-Mon D-Mon (emon.com), which has been a workhorse of the electrical monitoring industry. The E-Mon products are targeted at commercial, industrial, multi-tenant facilities. Many electricians are familiar with these robust revenue-grade metering products, which start at $400.
But for monitoring a single source, the Blueline, OWL, or Wattvision products are good candidates. For monitoring a few circuits with some optional features, the EnviR and TED will probably do the trick. With more rigorous monitoring requirements, the eGauge, eMonitor, or LGate are the meters worth considering.
