How to delete Fibaro Dimmer 2 switch

I had a Fibaro dimmer 2 switch in my old kitchen.
I’ve since removed it from the wall and want to delete it from ST and getting this. I click on link and website doesn’t exist. :thinking:

If the dimmer module has power, when starting Z-wave exclusion, if you triple click the button on the module, you should get a successful Z-wave exclusion message in the app.

It doesn’t have power unfortunately
