@gopher.ny is Hub Mesh supposed to be enabled by default?
I've never knowingly enabled it and today I happened to be wiresharking an issue with a different piece of hardware and noticed a load of UDP packets from my Hubitat hubs.
Closer inspection showed them to be from Hub Mesh and on looking at the settings on each hub it's enabled on all of them.
I've disabled it now, but would have thought this should have been an opt-in feature as opposed to automatically being enabled by default?
