ESPHome device configured, stays offline and appears as adoptable. why?

Hi all,
A few weeks ago I added my first ESPHome device, the Atom Echo. This went suprisingly werll.
So, yesterday I’ve added my Tasmota Zigbee Bridge (ZB01) with ESPHome.
Flashing succeded, And Zigbee2MQTT picks it up and all works well.
But, In ESPHome the config stays offline. (although I can re-flash it and see the logs and enter the web page). And ESPHome shows a new device that can be adopted (beeing the ZB01).
Why? and how to fix this?

The yaml in the ESPHome is as followed:

  name: "athom-zigbee-gateway"
  friendly_name: "Athom Zigbee Gateway"
  room: "Hal"
  device_description: "athom eth zigbee gateway"

EDIT:
Found it.
Enabled Ping instead of mDNS in the config of ESPHome.
Now it found it.
