Hello
I’m wondering how to pass a parameter to executeCommandLine.
I want to control brightness of LED by PIGPIO with pigs command (pigs p gpio_number pwm_value). So I created item:
and slider in sitemap.
But I’m stuck on my rule, as I’m not sure if PWMValue is passed correctly in executeCommandLine:
rule "LED1 dimmer"
when
Item LED1 received command
then
val DimmerPercent=LED1.state as DecimalType //Input Level
val PWMValue=(((DimmerPercent*255).intValue)/100).intValue //Calculating Value for PWM
executeCommandLine("pigs p 21 {}", PWMValue)
end
In log viewer there is no info that executeCommandLine happend.
How to pass PWMValue to executeCommandLine correctly?
I changed my code a bit to round the value for PWM and to see what’s happening in LogViewer. But it still doesn’t work
rule "LED1 dimmer"
when
Item LED1 received command
then
var DimmerPercent=LED1.state as DecimalType //Input Level
logInfo("demo.rules", "Percent from dimmer " + DimmerPercent)
var PWMValue=((((DimmerPercent.intValue)*255).intValue)/100).intValue //Calculating Value for PWM
logInfo("demo.rules", "Value for PWM " + PWMValue)
executeCommandLine("pigs p 21 {}",PWMValue)
logInfo("demo.rules", "Command executed")
end
