Node-red-contrib-shelly Troubleshoot

Hi All,

I have installed [node-red-contrib-shelly] on my Victron Cerbo.
I can connect to my Shelly device if it is on the same network as my Cerbo GX.
However, if I try to connect to another Shelly device which is on a different network than my Victron Cerbo, I can't access it.

Therefore, I would like to know how I can connect my shelly device to my Cerbo's Node Red when the shelly is on a different network.
