433mhz QIA-chip switch wiring issue (12v/230v)

[JanC]

Hi,

Just received a few switches to replace a current light switch in my home.
Due to the picture I supposed that I would be able to connect the 230v to the com, the null to V- and the black wire to the NO.
This doesnt work!
As soon as I connect a 12v wire to the V+ it is working, but unusable as a switch for 230v.
What sense does the 250v in the drawing make and is there a way to connect them anyways or should I order some other switches?

Thank you for answering...
I bought it at ali-express with the purpose of using it on 230v but I'm getting convinced of the fact that it aint working without a 12v-dc
