Expire works on updates, not changes.

See -

> [@Expire timer does not always work](https://community.openhab.org/t/expire-timer-does-not-always-work/114568/3):

> 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.
