go to OH console and run
bundlr:list | grep Shelly
I suppose you‘ll see 2 entries
- remove the shelly har from the addons folder
- re-run the command to get the id of the trmaining one
- use „hundle:uninstall id“ to get rid of the 2nd one
- stop OH
- run openhab-cli clean-cache
- start OH, wait a minute
- copy shelly jar to addons folder
- noe you should only have 1 instance in bundle:list and no duplicate thing types
- use auto discovery/Scan - no need to add things manually
