Problems adding LOGAREX SmartMeter to Home Assistant

Hi,
im new to HA and wantet to add my power consumption to my HA. Unfortunately i have a LOGAREX LK13BE 8030x9 and it seems that i can not use this LED because it is not IR.
The other option is, to use the optical control unit. But how does this work? I installed HA on my Synology NAS using Virtual Machine Manager.
