Zigbee2mqtt 2nd server: autodiscovery?!

Hi,

I am still new to zigbee, but I integrated an SMLIGHT SLZB using my hassio and zigbee2mqtt.
Now I have a raspberry pi with a CC2531 USB dongle, where I also installed zigbee2mqtt (standard raspbian).

So far so good, the devices from the SLZB are also added automatically to HA.
But altough I turned homeassistant to true in the configuration.yaml of the raspberry and I can see the mqtt-publish under homeassistant/binary_sensor/1221051039810110197122_0x00124b001949dcfa/connection_state/config no devices are auto-created in HA. What did I miss?

no glue why, but now the devices appeared… strange
