the UI button in the UI says my config is fine, but I still get the message:
The following components and platforms could not be set up:
* [device-tracker](https://home-assistant.io/integrations/device_tracker/)
Please check your config
The UI checks for syntax. Your problem is that many versions ago, the unifi device tracker was moved to it’s own platform, and no longer sits UNDER device tracker. Remove the unifi section under the device tracker domain.
Did you have made it work the integration of unifi controller on Hassio? I try for hours to integrate, with UI or Yaml but nothing, i recevie the message : no Service
if i test the connection on a PC from same Subnet it works.
