Send command only if requested status is not true

[Razeeer]

Hello @hans-1
thanks a lot for this great plugin. I noticed one thing that could be improved.

If a switch is included in a scene that turns off all devices, for example, this switch is always activated even if it is already off. This is of course bad for devices that have only one command for on and off, because the device will be switched on unintentionally when the scenes are activated.

This is unfortunately a circumstance that Apple pretends.

I know from other plugins that it is possible to add a check that the switches are only activated if they do not already have the requested state.

@hans-1 would it be possible to add this function to your plugin? I would be very happy about it.

Regards!!!
