Evcc Eebus wallbox integration

Hi, I’m using Home Assistant installed as an ova-image on a synology nas running virtual machine manager (vmm). Evcc is installed as an addon and running fine with one wallbox. Adding a second Eebus wallbox results in crash of Evcc, although the same evcc.yaml works in a stand-alone Evcc-debian-system.
The log of Evcc running as an addon in HA shows “eebus: machineid: machineid: open /etc/machine-id: no such file or directory”.
Creating machine-id manually under /etc/ is not successful.
Can anybody help?

Hey, any progress? I’m having the same problem. Elli connected via WIFI, certificate generated in windows and then inserted into yaml.
