Homey + fibaro smart implant + siren

I’m so happy with my Homey, every day I add a new domotic function.
My next step will be adding a siren. Homey flow + Heimdall + several Fibaro devices are ready.
I tried to add a Aeotec siren gen5, works bad, sometimes Homey sees it, sometimes not… Even after reset.
So after reading a lot of post here, I bought a Fibaro smart Implant and a classical siren (Altec sx) with SIR wire as command.
My question, does anybody here already tried to use a smart implant with a classical siren?
Does it work fine?
Thanks a lot in advance
