Hi! I love the proximity sensor bit would request one change: the ability to set a numerical precision, i.e. the number of decimal points for a calculated value.
As an example, I like to use proximity to determine how close I am to home, and for convenience, I prefer to use miles as the unit. (Why yes, I am American, how did you guess? 
) However, this results in limiting the usefulness of the sensor… For instance, it will often read as stationary even though I’m clearly moving around often by several city blocks.
If I could set the numerical precision or decimal points of the sensor, this would be great. Then I and my automations could detect a change from e.g. 0.6mi to 0.5mi.
I know there are other ways around this, such as using a smaller unit, and/or creating template sensors to calculate a more precise value. However, this feature seems like it’d be relatively simple to implement with potentially significant benefits.
