Hue light metadata

Hi all,

While setting up metadata information for my items to work with Google Assistent, I noticed that Philips Hue items automatically appear in GA as soon as you connect the Openhab Service to it. Now, all items are registered as lights, and I have a wall plug that operates my pool pump. Without success, I tried to add metadata manually to the wall plug item and set it to a common switch. I didn’t find why these items came with metadata out of the box.

Any ideas on how to solve this and change metadata for Hue items?
