Many thanks to rpertusio for the BlueStacks suggestion! Emporia should promote this, at least as an interim step before releasing their own web-based interface.
BlueStacks/Emporia works great, and with a modern GPU/CPU offers excellent performance. Downloading CSV files is also trivially easy.
Though it is amusing to launch a gaming platform to check energy consumption. 😀
We would not have purchased the Vue Home Utility Monitor without a desktop interface. Browsing detailed data on a mobile device is… sub-optimal. 😏
But our experience with the utility monitor has been so positive that we’ll be installing a 3x Vue system (main + two sub-panels) shortly if the ‘nesting’ works as advertised.
