the number.mycar_charge_limit and number.mycar_charge_current are forced by code to be presented as a digital input box by the following line : https://github.com/Teslemetry/hass-teslemetry/blob/54b9da01b991320d1ce0ee405832735d406cf4fe/custom_components/teslemetry/number.py#L76

Describe the solution you'd like

However, the "slider" is much easier to use in my opinion, and that option is unlocked by not forcing the input to be a box. Consider changing this line to

mode=NumberMode.auto,

Which is in-line with recommended practice in HA documentation.

Additional context
