I used to have a good My Solar Divert app showing the amount of excess PV going in to my HW, but I have lost track of it since getting a Powerwall, and would like to renew it all. So little diverted energy goes in to the HW now that I am going to ignore it.
But I am not quite sure how to handle the fact that the Powerwall can “consume” energy as well as give it out - unlike a HW tank.
The required fields are …
Use (total use in watts, inc diversion)
Use_kwh (cumulative total use in kWh)
- is this just the data from a CT on my main “Mains IN” cable, or do I need to filter out exports?
Solar (pv generation in watts)
Solar_kWh (cumulative solar generation in watts)
- easy to determine
Divert (Immersion usage in watts)
Divert_kwh (cumulative divert energy in watts)
- the obvious thing to use would be my “Powerwall IN” feed, as opposed to either my Powerwall OUT or Powerwall NETT feeds, but that would include energy going in during the night time cheap rate, so it’ll be too high. How might I resolve this
Import_kwh (cumulative grid import in kWh)
- do I need to create a feed that filters out any exports?
