Aeon Labs Smart Energy Switch: unexpected child devices

I have a Aeon Labs Smart Energy Switch since many months.
It is this model: http://www.domadoo.fr/produit,2577,1,AEON-LABS--Module-prise-commutateur-Z-Wave-avec-mesure-d-?nergie.htm

Few days ago, for a reason I ignore, 10 child devices of type BinaryLight have been created. The parent of these devices is the normal and usual device of type BinaryLight that I use to control the device. They are named 1, 2, …, 10 and they have e1, e2, …, e10 as altid.
I tried to delete few of them but they are automatically created again !

Why did I get these devices ? Why now ? How to suppress them ?

I 'm experiencing similar issues. this just popped out of no where. i thought it was solar panel inverters, but it was not,

can anyone assist with this.
