It depends on the devices.
A proxy is really just a proxy: It acts as an extension of the HA bluetooth to extend range.
Next is to add those devices to HA, whether by auto-discovery or manually, depending on the installed integration handling them, if any.
@koying Many thanks for your answer !!!
Can you confirm proxy is setup correctly from pictures ?
and that esp32dev in bluetooth is de-activated is right behavior ?
I can not re-enable it, so thats why I’m not sure this is working properly and this is the cause devices are detected but not lead to new integration or sensors
