OH3 Item Expiration Timer gets fired athough nothing changed

[rossko57]

@csand

the timer now gets fired every 15 seconds although nothing changes

Expire works on updates, not changes.

See -

Expire timer does not always work

Expire timer restarts when the target Item receives any update. I expect your zwave switch is issuing routine status messages every 15 minutes? Expire does not solve all timing requirements, sometimes you need rules.
