I've tracked a fair bit of data relating to mpg on our last four vehicles. With a new Clarity Base in the garage, it's time for another Excel file. But I can't quite wrap my head around a method to track this data. Has anyone created an Excel spreadsheet for this? Maybe tracking kWh sent to the battery, miles driven, etc. As the time comes to plan for 240v wiring, why would I want wifi on my L2 EVSE? https://www.amazon.com/dp/B00YY1KOHA this looks great for metering a dedicated 240v charger circuit, but maybe there's something better? Tracking kW usage would be related to cost to operate.
