Hi friends, as the title, my question is how to convert RGB string to HSB string and vice versa in .rule file? I created this .rules file to convert RGB to HSB values but didn’t success: import java.awt.Color var HSBType hsbValue rule "RED DIMMER" when Item WIFI_RGB_RED_DIMMER received comma…

I don’t see where you’re assigning/declaring redValue, greenValue, and blueValue. Did you omit that from your posting, or is it missing from your rule too? Also, color.toString returns something like this: java.awt.Color[r=100,g=75,b=55], which I don’t think is accceptable in the HSBType constructo…

Oh I forgot to post those variables from my post. They do exist in my rule file I declared outside the rule “Red DIMMER” Then I moved it inside the rule, like this: rule "RED DIMMER" when Item WIFI_RGB_RED_DIMMER received command then var int percent = 100 if(WIFI_RGB_RED_DIMMER.sta…

[image] Nguy_n_Phuc_Anh_D_ng: var redValue=percent var greenValue = 75 var blueValue = 55 These should probably include the type: var int redValue=percent var int greenValue = 75 var int blueValue = 55

@marcel_erkel OK, I changed: rule "RED DIMMER" when Item WIFI_RGB_RED received command then var int percent = 0 if(WIFI_RGB_RED.state instanceof DecimalType) percent = (WIFI_RGB_RED.state as DecimalType).intValue if(receivedCommand==INCREASE) percent = percent + 1 if(receivedComma…

As previously stated, this is never going to work as an input to the HSBType constructor: [image] namraccr: java.awt.Color[r=100,g=75,b=55] It needs a string in the form “val1,val2,val3”, where each is a string representation of an acceptable value for H, S and B.

How about this: Add the following import: import java.util.List rule "RED DIMMER" when Item WIFI_RGB_RED received command then var int percent = 0 if(WIFI_RGB_RED.state instanceof DecimalType) percent = (WIFI_RGB_RED.state as DecimalType).intValue if(receivedCommand==INCREASE) percent…

For completeness, here’s my test code which includes the conversion from RGB to HSB and from HSB to RGB: Required imports import java.awt.Color import java.util.List // from RGB to HSB val List<Float> hsb = Color.RGBtoHSB(250,150,50,null) val float hue = hsb.get(0) val float saturation = hsb.…

You can use this to convert into HSB:

hsbValue = HSBType.fromRGB(redValue,greenValue,blueValue)
