Fix Ikea Fyrtur state/on value

[IPSAttain]

Behaviour of command "state/on" differs from IKEA kadrilj device .
Also before implement that devices as DDF, it was different.
"state/on" must be true, if "state/lift" > 0

Right, nice catch.
But state/on is deprecated ATM, it's still so important for you third app (cause issue) or it's a just correction.

Hi Smanar,

thx for confirmation.
Yes this causes issues in our implementation. We have a general implementation for every "dimmable light" .
If the light state is off, it will force the dim-value to 0. In the UI you will see the brightness if the state is "on"/true only.

This DDF implementation shows me the brightness always as 0 until it reached the 100%

`
if (property_exists($Payload, 'bri')) {
$bri = ($Payload->bri>1)?round($Payload->bri/2.55):$Payload->bri;
if (property_exists($Payload, 'on')) {
if(!$Payload->on) $bri = 0; // force the dim value to 0, if state/on is false
}
$this->SetValue('Z2D_Brightness', $bri);

}`

Yeah better to have good value, even it's not used every where.
One day state/on and state/bri will be removed for covering device, but I think your code already manage it with if (property_exists
