A question

I would like to get a signal to my FHEM software when 230 volt power is
switched on with a regular switch. I googled a lot on this but didn´t find
a good way to do this.

I use a FB7390 and a TrxFrx433 of RFXCOM.

Thanks for any suggestion.

Have you considered FS20-FMS yet?

Use FS20 KSE - Bell Ringing Detector - plus some external components.

Yes but that wouldn't function.

I would like to use it in a situation where pir sensors switch the light.
If I can send a signal to the  FHEM software when the light is on, it can
be used for some kind of security  too.
I now think the KlikAanKlikUit AWMT-230 does this, but it uses a battery as
a power supply. I don't like the idea of having to open the ceiling every
year to change batteries. I know they say about 5 years. But pir sensors
will switch more often as a wall switch and so the batteries will go empty
much earlier.

Yes it would. Think twice, please.
