Short and long press differentiation

[derc...@googlemail.com]

Hi folks,

I want to use something to distinguish between short and long presses of buttons. There are rules like:

rule "Schalter_EG_Bereitschaft"
when
    Item Schalter_EG_Bereitschaft changed
then
    if(Schalter_EG_Bereitschaft.state == 1)
    {
        timer = createTimer(now.plusSeconds(3))
        [|
            if (bereitschaft == false)
            {
                bereitschaft = true
                sendCommand(Lichter, OFF)
                sendCommand(Steckdosen, OFF)
                sendCommand(Hinweis_STANDBY, ON)
            }
            else
            {
                bereitschaft = false
                sendCommand(Strom_EG_WZ_HiFi, ON)
                sendCommand(Hinweis_STANDBY, OFF)
            }
        ]
    }
    else
    {
        if(timer!=null)
        {
            timer.cancel
            timer = null
        }
    }
end

Now I'd like to create a rule that does a different action on long and short press:

Example:
Press button for 1 second, excute rule 1, but keeping the button hold for >3seconds execute rule 2 without influencing rule 1.

Thanks for help,
Carsten

I am pretty new for openHAB, but maybe it can be done in these ways (unfortunately I don't have openHAB installed now, so it is just an idea, not tested).
1. Both short-click and long press reacting on button release and we manually counting how long it was pressed:

import java.util.Date

var long lastButtonPressTime

rule "short_long_press_v1"
when
  Item MyButton changed
then
  if ( MyButton.state == 1) {
    lastButtonPressTime = new Date().time
  } else {
    if (new Date().time < lastButtonPressTime + 3000 ) {
      // do short-click stuff
    } else {
     // do long-click stuff
    }
  }
end

2. Short-click react for button release but long-press react for timeout:

import org.openhab.model.script.actions.*

var Timer longPressTimer = null

rule "short_long_press_v2"
when
  Item MyButton changed
then
  if ( MyButton.state == 1) {
    longPressTimer = createTimer(now.plusSeconds(3)) [| /* long-press stuff */]
  } else {
    if (globalLihghtOffTimer != null) {
      var boolean cancelled = longPressTimer.cancel
      globalLihghtOffTimer == null
      if (cancelled) {
        // do short-click stuff
      }
    }
  }
end


P.S. Seems like GoogleGroups don't work good with Opera, so I don't know if my previous reply wasn't sent or this is just premoderation. I'm sending it in the second time, sorry if it will be double.

Found a mistake, in the second example globalLihghtOffTimer should be replaced by longPressTimer.

Hey Alexandr,

thank you very much for your examples. I've implemented the second one cause I need immediate response if timer expires. And it works like a charm!

Some minor changes to make it more compact. The result looks like this:


import org.openhab.model.script.actions.*

var Timer longPressTimer = null

rule "short_long_press_v2"
when
  Item MyButton changed
then

  if (MyButton.state == 1) {
    longPressTimer = createTimer(now.plusSeconds(3)) [| /* long-press stuff */]
  } else {
    if (longPressTimer != null) {
      if (longPressTimer.cancel == true) {
         // do short-click stuff 
      } 
      longPressTimer = null
    }
  }
end

Thanks again,
Carsten
