Challenge : LUA scene for KeyFob volume buttons

[peterburgering 0]

Hi all, I have a HC2 and I am trying to connect my KeyFob to my Sonos Playbar to set the volume. I already have it working but now I am finetuning and cannot get to the end. I have programmed my "+" and "-" button on the KeyFob so that they set the volume up and down. But I want to have it more sophisticated. My goal is when I push "+" the volume goes up by 1 on every click. And goes down by 1 when clicking the "-" button. But I need some help with this. 

Does someone here know how I can create the correct LUA code for this?? 

 

Here below the current situation in the scene for the KeyFob:

 

--[[
%% properties
%% events
263 CentralSceneEvent
%% globals
--]]

local sa = fibaro:getSourceTrigger()["event"]["data"]
--fibaro:debug(json.encode(sa))

if ((sa['keyId'] == 1) and (sa['keyAttribute'] ==  'Pressed'))
  then 
  fibaro:debug('key1') 
end

if ((sa['keyId'] == 1) and (sa['keyAttribute'] ==  'Pressed2'))
  then 
  fibaro:debug('key1 double') 
end

if ((sa['keyId'] == 1) and (sa['keyAttribute'] ==  'Pressed3'))
  then 
  fibaro:debug('key1 triple') 
end

if ((sa['keyId'] == 1) and (sa['keyAttribute'] ==  'HeldDown'))
  then 
  fibaro:debug('key1 held') 
end

if ((sa['keyId'] == 1) and (sa['keyAttribute'] ==  'Released'))
  then 
  fibaro:debug('key1 release') 
end

if ((sa['keyId'] == 2) and (sa['keyAttribute'] ==  'Pressed'))
  then 
  --fibaro:debug('key2') 
  fibaro:call(348, "setMute", "1")
end

if ((sa['keyId'] == 2) and (sa['keyAttribute'] ==  'Pressed2'))
  then 
  --fibaro:debug('key2 double')
  fibaro:call(348, "setMute", "0")
end

if ((sa['keyId'] == 2) and (sa['keyAttribute'] ==  'Pressed3'))
  then 
  fibaro:debug('key2 triple') 
end

if ((sa['keyId'] == 2) and (sa['keyAttribute'] ==  'HeldDown'))
  then 
  fibaro:debug('key2 held') 
end

if ((sa['keyId'] == 2) and (sa['keyAttribute'] ==  'Released'))
  then 
  fibaro:debug('key2 release') 
end

if ((sa['keyId'] == 3) and (sa['keyAttribute'] ==  'Pressed'))
  then 
  fibaro:debug('key3') 
end

if ((sa['keyId'] == 3) and (sa['keyAttribute'] ==  'Pressed2'))
  then 
  fibaro:debug('key3 double') 
end

if ((sa['keyId'] == 3) and (sa['keyAttribute'] ==  'Pressed3'))
  then 
  fibaro:debug('key3 triple')
