Prevent discovering multiple devices for one hardware device?

[dagobert]

I have a smarkt plug that has the switch for turning on/off the attached device. This switch also exposes a light entity to en-/disable a LED indicator light. The result is that powercalc discovers it twice.
In general it is a good idea (see Aqara light with two lights integrated) but here it is not. I can ignore the LED light indicator but a nicer solution would be an option in the model to prevent this.

Or am I missing something?
