[FEATURE REQUEST] circle color for values=0

[cpohli]

Is your feature request related to a problem? Please describe. I do have times, when my grid has neither production or consumation values. The color of the ring seems to keep it's last state.

Describe the solution you'd like I would very much appreciate an option for the ring color being selectable if value is 0 (real 0 or "display_zero_tolerance" 0). My (personal) idea of configuration would be red-consumation, green-production, grey-value0. That i would apply to grid, battery and individual (which is my car. charging-red, not charging-grey).

Describe alternatives you've considered I considered to hide the circles when values are 0 (already possible), but i have configured secondary infos, that i like to see even when actual values are 0.

Again, thank you for you efforts with this card. It's so damn useful for a quick glance and overview. It's my most looked at card at the moment :-)
