Can't tag thing using Habmin for Homekit on Openhabian

I’m trying to tag my wemo switch so I can control it with Eve app. I get an error when I add the tag “switchable” to the wemo switch. I added the homekit.cfg to the service directory and added the port, pin , and network interface to it.
Any suggestions? I’ve added a tag before this way but never got an error.

The the message on the third screenshot looks like you are trying to tag an item defined in an .items file. I guess this is not possible in Habmin and must be done in the .items file instead.

The syntax for tagging in .items files can be found here:
