Shelly Plug S (consumption (W)) with HWiNFO

Would like to read out the current total consumption at the socket (Shelly Plug S) in real time with HWiNFO.

How do I get HWiNFO to read Shelly's information (static IP on the network)?
We have no information about this device's protocol and how to access the relevant information. Does it have a web interface or USB perhaps?
This is a quite high-level interface, not ideal for integrating into HWiNFO.
There's a possibility to use a custom user sensor to import data from other sources into HWiNFO. But someone would need to write a wrapper from its MQtt/web interface into the format (registry) for that custom sensor.
