Lambda Help

Setup, Configuration and Use Scripts & Rules

1

I’m working on setting up my first Lambda to use for making execution of a bunch of switch scenes easier. I’m using the HomeSeer devices which support the double/triple tap options. To make life easier, I’d like to setup a lambda to re-use for multiple different switches, rather than the messy If statements and copying code over multiple times and editing each unique aspect. For some reason, this is not running, but I’m not seeing any errors either helping to point out what I may be missing.

Any help is greatly appreciated, as I’ve never used Lambdas before and seen some difficulty folks have had here even when they’ve used them before.

// Switch scene Lambda
val Function7 hsScene = [
  NumberItem  sceneId,
  Procedure0  singleOn,
  Procedure0  singleOff,
  Procedure0  doubleTapOn,
  Procedure0  doubleTapOff,
  Procedure0  tripleTapOn,
  Procedure0  tripleTapOff  |

  switch(sceneId.state) {
    case 1.0: {if (singleOn != null) singleOn.apply() }
    case 2.0: {if (singleOff != null) singleOff.apply() }
    case 1.3: {if (doubleTapOn != null) doubleTapOn.apply() }
    case 2.3: {if (doubleTapOff != null) doubleTapOff.apply() }
    case 1.4: {if (tripleTapOn != null) tripleTapOn.apply() }
    case 2.4: {if (tripleTapOff != null) tripleTapOff.apply() }
  }
]
