Shelly pro 4pm networking issues

[Hamid]

Good afternoon,

I am very new to home automation and shelly devices, hence, I need the community's help.

I have a large garden, with several lighting, water pump and power circuits. These circuits are connected to an electricity consumer unit housed in a Metal waterproof box with its own 240v, 32A supply cable. I have installed 2 Shelly Pro 4pm devices in the consumer unit. However, due to the Faraday cage effect, of the Metall box, I cannot get WIFI signal to the devices. Hence, I have an ethernet cable, which may be connected to one of the devices. I wonder if I can use the Range extender, of the ethernet-connected device, to connect the second device to my network. If that is possible, please advise as to how it may be achieved>

Many thanks.
