I agree that you strictly speaking do not need an energy monitor to know when to charge your vehicle in your situation. When on NEM 2 and on a TOU plan, you should consume power as if you don’t have solar, i.e. for most TOU plans that typically means EV charging from midnight to 6 weekdays and midnight til 2 pm. on weekends.
The only exception to this would be if your solar array is significantly oversized, in which case it becomes less important as the NEM 2 true up pays you a pittance for net excess kWh’s come true up time.
That being said, I find the energy monitor to be hugely helpful as it allows you to monitor solar production and all of your high power consumption devices such as el dryer, heat pump, AC, water heater etc, etc. If you are close to being in balance on a yearly true up basis, it will help you to know what to focus on in terms of other appliances etc. to ensure that you end minimizing/eliminating any true up payment.
The only issue I have is that the utility rates are outdated. The app allows you to select your TOU plan (in our case SDGE EV-TOU-2) but in looking at the consumption stats it seems to apply rates that are 1+ year old.
