I have two power sensors coming from my EV changer:
- prism_potenza is the power provided to the car
- prism_power_grid is the total power drawn from the grid (house+EV)
I have created a 3rd sensor to get the power used by the house (by difference)
- platform: template
sensors:
prism_potenza_casa:
value_template: "{{( states('sensor.prism_power_grid') | float(0) - (states('sensor.prism_potenza') | float(0)) ) | round(3) }}"
unit_of_measurement: "W"
The EV charger is setup to hover around 6kW (total grid draw) and I noticed that every time it stops charging there is a 6kW spike on the “house power” sensor (“prism potenza casa”
This seems to be due to the fact that the 2 sensors don’t update exactly at the same time, is there a way to fix this?
