My electrician plugged this thing into the 3-socket outlet in the server cabinet and connected the power strip to it. This was done during the renovation of the house, where the entire electrical distribution was redone and only RCDs are now present. Does this thing do anything except make the electrician money and cover two of the three plugs in the triple socket?

I wouldn't hang it in front of my server. It is very sensitive and has already tripped on me from time to time without me being able to see a reason. The RCD is more about personal protection, I personally don't see the need for it in the server cabinet - especially if the whole house already has RCD switches.

I have a Powerstation Ecoflow delta max that I connect to the motorhome's external socket. Would this be fused with this Fi switch plugged in?

RCDs measure the differential current. So if the current is discharged incorrectly somewhere, it trips and thus protects. If you have your own/autonomous power supply, you will hardly have a real earth and the current is not discharged anywhere, which means that in many cases the RCD will not notice anything. It would protect a little if there were continuously earthed cables and faulty equipment insulation somewhere. If, on the other hand, a single bare live cable (without contact to the earth conductor) is touched somewhere, nothing happens with or without a residual current circuit breaker. In this case, the RCD is of somewhat less use than usual. However, it is not a bad idea to use it, especially if it is also used in a stationary power supply (where not all installations have an RCD).
