RFXtrx433E battery powered relay.

I am trying to source a battery powered relay switch
Compatible with them and RFXtrx433E.
I do not have a neutral connection at the switching point.
The Aoke mentioned in rfxcom manual looks ideal

But i suspect it is unlikely to be supported by Fhem?

Appreciate your thoughts/ comments
