Creation of redundant loadpoints within Sunny Portal / Sunny Home Manager 2.0

Description

The SMA Sunny Home Manager integration of SMA via the SEMP protocol leads to the creation of redundant loadpoints within the Sunny Portal. I have one wallbox, which is exposed to the Sunny Home Manager via EVCC and I have not changed anything about the standard configuration since it became enabled per default. I now have 3 different "Non-controllable loads" for the same wallbox, of which only one is actually displaying energy values. I know that there were only 2 when I checked the last time. In the event monitor of SMA I can see that it regularly registers "EM devices" but that was happening regularly before it created additional loadpoints. I cannot tell if the behavior is caused by SMA or by evcc. It might also be some artifacts of energy usage which were not correctly attributed to the wallbox. I'll try to attach screenshots. I cannot pinpoint to a specific date/time when the loadpoints were created. I registered the loadpoint once within the sunny portal after being promted about it, when evcc was setup.

Steps to Reproduce

Run evcc
Run SMA Sunny Home Manager
Unwanted creation of additional redundant loadpoints after normal operation within Sunny Portal
