@electroman00, your statement of “Currently the Gen 2 Vue does NOT make any direct connection to the electrical system to enable voltage measurements.” is categorically and definitively false.
The Vue2 device literally has a physical connection to leg A, leg B, Neutral, and Ground (this is what the 4-wire connector connects to). So, the “direct connection to the electrical system” needed in order to provide voltage monitoring definitely exists. If what you’re saying is that the internal wiring within the Vue2 device doesn’t connect these 4 leads to an input or sensor that can read analog voltages, then fair enough, voltage tracking is impossible due to hardware limitations.
Unless you either work for Emporia or have taken a Vue2 device apart and reverse engineered it yourself, you’re probably not in a position to declare that the hardware renders this feature impossible.
I for one, hope that these 4 leads are wired to input pins on the microcontroller that happen to have the capability to read analog voltages (ADC capability). If this is the case, then it really is just a matter of some programming on Emporia’s part and pushing out a firmware update to enable the ADC feature of these pins and allow the Vue2 to perform voltage sensing.
