Status of item (String) is not updated

Hello
I’m trying to run a rule to know the wind direction with the data that come from openweather, but it does not change the item, I was wondering if you know why, here are my sitemap and items.

when
Item LocalWeatherAndForecast_Current_WindDirection changed
then

if(LocalWeatherAndForecast_Current_WindDirection.state > 0 || LocalWeatherAndForecast_Current_WindDirection.state < 49.9 ) {
	direc_viento.postUpdate(" N ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA N")
}

if(LocalWeatherAndForecast_Current_WindDirection.state > 50 || LocalWeatherAndForecast_Current_WindDirection.state < 89.9 ) {
	direc_viento.postUpdate(" NE ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA NE")
}
if(LocalWeatherAndForecast_Current_WindDirection.state > 90 || LocalWeatherAndForecast_Current_WindDirection.state < 129.9 ) {
	direc_viento.postUpdate(" E ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA E")
}
    if(LocalWeatherAndForecast_Current_WindDirection.state > 130 || LocalWeatherAndForecast_Current_WindDirection.state < 179.9 ) {
	direc_viento.postUpdate(" SE ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA SE")
}

if(LocalWeatherAndForecast_Current_WindDirection.state > 180 || LocalWeatherAndForecast_Current_WindDirection.state < 229.9 ) {
	direc_viento.postUpdate(" S ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA S")
}
if(LocalWeatherAndForecast_Current_WindDirection.state > 230 || LocalWeatherAndForecast_Current_WindDirection.state < 269.9 ) {
	direc_viento.postUpdate(" SW ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA SW")
}
if(LocalWeatherAndForecast_Current_WindDirection.state > 270 || LocalWeatherAndForecast_Current_WindDirection.state < 319.9 ) {
	direc_viento.postUpdate(" W ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA W")
}
if(LocalWeatherAndForecast_Current_WindDirection.state > 320 || LocalWeatherAndForecast_Current_WindDirection.state < 360 ) {
	direc_viento.postUpdate(" OW ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA OW")
}

end

greetings and I await your answers

Do any of the logInfo statements show in your log?

Additionally your conversion of directions is wrong!

rossko57 · May 30, 2019, 11:13am

I’ll bet LocalWeatherAndForecast_Current_WindDirection has UoM and is expressed in degrees. (a Number:Angle type)

You’d need to extract the number part only, or compare with angles.

mdepablo · May 30, 2019, 11:16am

thanks for the speed of response
nothing comes out in the log
Why is the conversion incorrect?

mdepablo · May 30, 2019, 11:17am

thanks for the speed of response
that item gives a number in degrees that’s why my conversion attempt

rossko57 · May 30, 2019, 11:22am

Yep, so you are comparing apples with oranges.
32 ° > 30

Try

if(LocalWeatherAndForecast_Current_WindDirection.state > 0 | "°" ....

to get both sides in degrees.

opus · May 30, 2019, 11:36am

When using 8 steps (N, NE, E,SE, S, SW, W, NW) each step has 45 degrees, the one for N goes from 337,5 over 360 to 22,5.

There are no log entries because of the problem mentioned by @rossko57

mdepablo · May 30, 2019, 3:08pm

I think I understand the fault, but when doing the rule to the system I would not give the same unit that puts only should act on the number, I do not know if I explained, and if not how I could fix it

opus · May 30, 2019, 3:12pm

Did you try the example as given by @rossko57?

rossko57 · May 30, 2019, 3:47pm

If you mean “how do I get just the number part of a number with units”?

(MyItem.state as quantityType).intValue

mdepablo · May 31, 2019, 10:57am

thanks for the help @rossko57 but I do not know how to use it, I searched but I do not see how, you can give me a little light

rossko57 · May 31, 2019, 11:02am

Instead of

use
if ( (LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue > 0 || ...

I think to save typing I’d do it once.

var Number xx = (LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue
if ( xx > 0 || xx < 50 ) {

mdepablo · May 31, 2019, 2:20pm

thank you very much, the first part if I understand it I think it would be like that

`rule “cambio de direccion”

when
Item LocalWeatherAndForecast_Current_WindDirection received update
then

if((LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue > 0 || (LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue < 49.9 ) {
	direc_viento.postUpdate(" N ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA N")
}

if((LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue > 50 || (LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue < 89.9 ) {
	direc_viento.postUpdate(" NE ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA NE")
}
if((LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue > 90 || (LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue < 129.9 ) {
	direc_viento.postUpdate(" E ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA E")
}
    if((LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue > 130 || (LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue < 179.9 ) {
	direc_viento.postUpdate(" SE ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA SE")
}

if((LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue > 180 || (LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue < 229.9 ) {
	direc_viento.postUpdate(" S ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA S")
}
if((LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue > 230 || (LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue < 269.9 ) {
	direc_viento.postUpdate(" SW ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA SW")
}
if((LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue > 270 || (LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue < 319.9 ) {
	direc_viento.postUpdate(" W ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA W")
}
if((LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue > 320 || (LocalWeatherAndForecast_Current_WindDirection.state as QuantityType<Number>).intValue < 360 ) {
	direc_viento.postUpdate(" OW ")
	logInfo("TIEMPO", "DIRECCION CAMBIADA OW")
}

end

`
I’m sorry but the second part I do not understand

when the rule works we will start if the conversion of the degrees is correct @opus

opus · May 31, 2019, 6:12pm

For a solution look into that one.

mdepablo · May 31, 2019, 9:10pm

hello the rule already works … but badly this is the log

he ignores the more and less, and I do not understand why.
thank you very much @opus then I will see how to modify the values

rossko57 · May 31, 2019, 10:14pm

You haven’t asked for more and less, you wrote more or less. Try

if ( xx >= 0 && xx < 50 )

mdepablo · June 1, 2019, 6:30pm

thank you very much to the two already works perfectly with this doubt I have learned to handle the variables “and, or”
