Feature release: support HA Beaufort windspeed unit type.

Feature: support HA Beaufort windspeed unit type.

Feature: render speedbar with evenly distributes speedranges.

Feature: new option to render the windspeed bar speedranges evenly distributed.

Currently the width of the block depends on the relative size of the speedrange.
With the new option render_relative_scale set to false (default true), the speedranges are rendered with the same size.
This option is part of the windspeed_entities configuration.

Example:
`
windspeed_entities:

• entity: sensor.wind_speed
  name: Speed
  speed_unit: auto
  use_statistics: false
  render_relative_scale: false
  `

Hide windspeed bars

Feature: new option to hide the windspeed bar(s): hide_windspeed_bar

Bufix: interval refresh broken

• Interval refresh fix.

Feature: new data period option

Before only the options hours_to_show was available and is now moved. This option is the old location is now deprecated but still works.

There is a new data_period object containing hours_to_show and from_hour_of_day.

The from_hour_of_day shows only data from that hour and forward. So set to 0 (midnight), the windrose only uses data of this day.
More info the readme.

Feature: custom entity wind direction letters.

• Feature: added option to modify the letters use by the direction entity for the cardinal directions.
  Some wind direction entities use language specific letters. No need to make an template sensor to convert these to the correct English. letters.

Short leaves fix

Fix: with center_calm_percentage true, the leaves won't use the available space, if the calm percentage is high enough.

Fix: ignored invalid values

• Unit of measurement kn now recognized as knots.
• Not recognized directions now ignored.
• Not recognized speeds now ignored.

Fix: ignore wind direction that are not a number.

• Ignore wind direction that are not a number.

Big feature release, breaking changes.

Big release, breaking changes:

The easiest way to update is to add the card to a dashboard and change the default generated configuration.

New features:

• Option to disable the center calm percentage and show the first speed range.
• Statistics data can now be used for winddirection and windspeed entities. Not all entities support this.
• Windspeed unit is automatic detected, see readme. Depends on the unit_of_measurement attribuut of the entity.
  If your windspeed entitiy uses an unit_of_measurement that's not recognized, please let me know. You can always configure the speedunit your self.
• Log level configurable, level INFO can give you some more information about measurement counts and speed units detected.
  Changes:
• Beaufort is not a speedunit any more. It's more like a speed range option. It can be turned on with a separate property. The Beaufort speed ranges depend on the output speed unit.
• Wind direction speed matching logic changed:
  • When NOT using statistics, when matching a speed to a direction, the matched speed is the last measurements before the measurement time of the direction.
    So also when you get speed updates once in an hour and direction updated every second, matches can be found.
    The direction_speed_time_diff property is not used anymore.
