Ok, here I am again,
I adapted the ezr2mqtt.yaml to my ip addresses and started the ezr2mqtt and the mosquito plug in. However, none diverse show up.
In the mosquito broker I get following protocol
[s6-init] making user provided files available at /var/run/s6/etc...exited 0.
[s6-init] ensuring user provided files have correct perms...exited 0.
