Windspeed bar range about lovelace-windrose-card

[aukedejong]

Yes, that would be an useful feature.
Also the option to define the colours per speed range.
I'll start working on that.

[aukedejong]

Good idea. I think adding two configuration options could fix this.
windspeed_bar_max: 20
windspeed_bar_step: 5

With this configuration the bar gets there ranges:
0 - 5
5 - 10
10 - 15
15 - 20
20 - infinity

The unit depends on the output unit configured. Defaults will also depend on the output unit.
When output unit is Beaufort (the default) an error shown, because Beaufort uses fixed speed ranges.

For now, you can set the windspeed_bar_full options to false.

windspeed_bar_full: false

This way the speed ranges that are not used, will not be rendered.

Released version 0.6.0.
Implemented what I described in my previous comment.

Very nice, thanks a lot. I'm going to try it this weekend.

This is great, thank you! Might it be possible to define our own custom steps? The use case for me would be more or less (semi) replicating the Beaufort scale, but in miles per hour. I find it helpful for the legend to show values in mph rather than the Beaufort number, as they're a more familiar unit to me. Relatedly, I'm generally interested in greater resolution at lower mph and less concerned about distinguishing anything above a near gale.

The handy custom:compass-card lovelace card uses a configuration where you can define start points for bands. For example, this is the relevant part of the configuration I have

indicator_sensors:
  - sensor: sensor.tempest_st_00086807_wind_direction
    indicator:
      type: arrow_inward
      dynamic_style:
        sensor: sensor.tempest_st_00086807_wind_speed
        bands:
          - from_value: 0
            color: green
          - from_value: 4
            color: yellow
          - from_value: 6
            color: orange
          - from_value: 8
            color: red
          - from_value: 11
            color: purple

Released version 0.7.0

Added speed_ranges configuration. Same style is the compass-card. There is an example in the readme.

Can you do some tests, see if everything is working as expected. Thanks.

[srwareham]

Thanks!! Testing now. The colors specification works but I 'm seeing something a bit odd with the binning. I tried recreating the beaufort scale using the m/s values used in the code. However, I'm getting different results.

I used the m/s thresholds defined in the code:

lovelace-windrose-card/src/WindSpeedConverter.ts

Lines 137 to 152 in 9222416

	private generateBeaufortSpeedRanges(): SpeedRange[] {
	const colors = new ColorUtil().getColorArray(13);
	return [
	new SpeedRange(0, 0, 0.3, colors[0]),
	new SpeedRange(1, 0.3, 1.6, colors[1]),
	new SpeedRange(2, 1.6, 3.4, colors[2]),
	new SpeedRange(3, 3.4, 5.5, colors[3]),
	new SpeedRange(4, 5.5, 8, colors[4]),
	new SpeedRange(5, 8, 10.8, colors[5]),
	new SpeedRange(6, 10.8, 13.9, colors[6]),
	new SpeedRange(7, 13.9, 17.2, colors[7]),
	new SpeedRange(8, 17.2, 20.8, colors[8]),
	new SpeedRange(9, 20.8, 24.5, colors[9]),
	new SpeedRange(10, 24.5, 28.5, colors[10]),

	new SpeedRange(12, 32.7, -1, colors[12])

Nice test. I'll try to reproduce and fix.

[aukedejong]

First try, I got 2 perfect equal windroses.
Next try, copy pasting your configs, they where not equal.

And found the problem. The input unit is mph on the first one en mps on the second one.
That explains it, you agree?

[srwareham]

Yes, apologies for wasting your time with that one 😞
But on the brighter side, looks like the implementation is good to go!

[aukedejong]

Happy to help.
