Adding 1-wire sensors to Fibaro Smart Implant

I’m trying to add some (6) DS18B20 1-wire temp sensors to my HA set-up using the Fibaro Smart Implant but I can’t find them. Is this entity hidden under some cryptic description or what? Would be nice to know what I’m looking for. In my struggle to get this to work I have added and removed the smart implant a couple of times (unsecure) and now I seem to have three instanses instead of one. Even after hours of searching forums and reading HA manuals I can’t figure out how to remove these extras, any help around that would be apreciated.
