Controlling openHAB with your voice / HSBType NullPointerException

Setup, Configuration and Use Scripts & Rules
1

Hi,
i found the Wiki entry “Controlling openHAB with your voice” It works fine, until the RGB part.

  } else if (command.contains("rot")) {
        newState = new HSBType(new Color(255, 0, 0));
    } else if (command.contains("blau")) {
        newState = new HSBType(new Color(0, 0, 255));
    } else if (command.contains("weiß")) {
        newState = new HSBType(new Color(255, 255, 255));
    }

When i place the voice command “licht flur rot” i recived.

  1. Did you import org.openhab.core.library.types.HSBType?
  2. Could you instead use HSBType::RED, HSBType::BLUE and HSBType::WHITE?

Hello Watou,

thanks for the reply.

Point 1 Yes/No - i have imported import org.openhab.core.library.types.*

to 2 - tried HSBType::RED instead of HSBType(new Color(255, 0, 0)) and got following

2016-03-09 18:51:01.914 [ERROR] [o.o.c.s.ScriptExecutionThread ] - Error during the execution of rule 'Voice control': index=0, size=0

In the meanwhile, i use this command to got an working rule.

if (command.contains("rot")) {
                        // Wenn eine Farbe angesprochen wird, dann RGB
                itemType = "beleuchtung_rgb"
                        // und entsprechende Farbe
                        itemSubType = "_rot"
                }

Thanks regards Mario

That might be the winner of the award for most obscure, least helpful error message ever. Glad you got it working another way!
