ZHA does not Create Zigbee network with SBT-2 coordinator

Situation:
i had a working zigbee network, but the Coordinator failed.
So i bought a new one, the SBT-2
But now After installing it i have no Zigbee network, no icon at HA->Devices&Services.
I see the device at Settings: Devices&Services-> Devices. Device shows only Firmware

anyone a idea what is happening?

logs are enabled but in Core logs i only see:
– – 0 0 1 1 0 2026-08-03 11:44:32.996 DEBUG (MainThread) [homeassistant.components.zha.radio_manager] Attempting to probe radio type RadioType.ezsp

Fix it… pfff

setup was ‘corrupt’

  1. went to Home assistant witch Samba. Config->.storage (=hidden file)
  2. open with e.g. notepad ‘core.config_entries’ , remove all entries with new and old coordinator.
  3. Open ‘core.device_registry’ and remove here also entries new and old coordinator.
  4. if present, delete ZHA config in configuration.yaml file
  5. now you can install ZHA again.

took me some time, but i also get the reward!
Peace
