Hi @heinemannj , I stumbled upon your post Googling and actually have the exact same need.
I want to use the powerflow plus card, not the standard energy card because I want to display a combination of power and energy. So at the grid I want to display Energy in kWh not power in kW, but like you I have the same problem. Although the entities I entered in the grid are in kWh and I add
unit_of_measurement: kWh
in the card code, it still shows as kW.
I am a bit of a HA novice, how did you solve this in the end? Thank you.
