Adding Node Through Fibaro Switch Route

[Nephylim]

Hi,
I've got a problem integrating a TRV into my Network,
the TRV is not reachable by the Controller itself because it is too far away.

I cant add it easily standing next to the controller but it isn't able to send any updates when installed at the radiator.
There is a Fibaro Switch between the two which schould work as a relay but I can't get it to work.

I already tried adding the node while being at the radiator. But it did not work. How can I add the Node to use the switch as relay to the controller?

Thank you for your help

Did you add it to the network, install on radiator (or put somewhere near) and perform a Z-Wave network heal?
This heal re-routes the traffic

That did it. Thank you
