Precision for secondary info & hiding numbers

[JonahKr]

Original issue by: @Lateadapter #131

1. Precision control for secondary info
2. Custom Color ranges: Duplicate of Allow custom ranges for colors #123
3. Possibility to hide (or recolor) the number of primary entity (originally my idea was to write the SOC-percentage as secondary info instead of the name and nothing at the place of arrows, but that is not possible; the hiding of the number itself would be possible by choosing an alternative attribute, but than the color threshold doesn’t work anymore)

very much appreciated, thanks

I’d be really keen to see precision control for secondary. The display seems to ignore the precision set on the sensor in the HA interface and uses the precision displayed in Developer > States which is provided by the integration. Some integrations provide a method to set precision but many do not as it is now selectable on the HA sensor configuration.
