Hi,
In upcoming HA release 0.118 the Shelly integration is not using aiocoap anymore.
beta for 0.118 is already out if you want to try it, if not I suggest to return here after 0.118 release.
Just to verify, which Shelly device did you try add?

@thecode Shelly1 and Shelly2

[thecode]

OK, These devices should be supported, hopefully 0.118 will be released within few days, please update and report back with the results.

Update done, everything works perfect now, THX!!!! 🙏

So please close the issue.
