Replicate status of two switches or dimmers

Developer's Corner Scene Scripting

Hi:

Which code could I use to replicate the status of two switches or dimmers? I.e if switch 1 is on, then switch two should be off and viceversa.
Same thing for dimmers.

Thanks!!

Easy to implement via GUI (setup two scenes and use the events ‘A device is turned on/off’), but IIUC you are asking for Luup code.

Untested (might require some additional typecasting …):


SwitchPower_SID = "urn:upnp-org:serviceId:SwitchPower1"

Switch_IDs = { 36, 42 } -- adjust accordingly

for i=1,#Switch_IDs
 do
  luup.variable_watch( "synchronize_SW", SwitchPower_SID, "Status", Switch_IDs[ i ] )
 end

function synchronize_SW( lul_device, lul_service, lul_variable, lul_value_old, lul_value_new )

 for i=1,#Switch_IDs
  do
   if tonumber( lul_device ) ~= Switch_IDs[ i ]
    then
     luup.call_action( SwitchPower_SID, "SetTarget", { newTargetValue = tostring( 1 - tonumber( lul_value_new ) ) }, Switch_IDs[ i ] )
    end
  end

end
