SMA load management with Shelly plugs/sockets

I just upgraded my SMA system to Home Manager 2.0 and all seems well. I have a couple of sunny boys and a sunny island. Managed loads now need different traduit controlled sockets. There are quite a few compatible devices in the SMA compatibility list but I cannot find any documentation on configuring the Shelly plugs. I had an Edimax plug so connected that fine, works a treat. I think the Shelly plugs are more versatile, but I cannot find a mention anywhere of how to connect them!
