Extend range with a fibaro relay switch

[Angel L. Mateo]

Hi,

I have installed some danfoss lc13 to control my radiators, but some of then doesn't reach the zwave controller.

So I have bought a fibaro double relay switch to extend the network (and to control some lights too). I have included it in the network, but my lc13 doesn't see it as a neighbor, although one of them is just a few meters from it.

Do I have to do a specific configuration? Is there any step to change the topology? Or it should be changed it just including the new device?
