Hello, it's a silicon ring that acts as a protection, you have to remove it to load the button, if you remove it it may slide more easily on a piece of furniture, but that doesn't change anything to its correct operation.
Hi Dasmuh88,
This is not the case for me. The power switches appear in GoogleHome, but the Wifi button does not.
I also have some difficulties in iobroker to integrate it. It appears there, but the events are not visible.
