OH3.1.0M3 running on centos 8. I’ve set up an expiration timer on a bathroom fan switch. When it’s set to say 5 seconds it works just fine. I reconfigure it for two hours which is what I want eventually and the fan never turns off. The toggle switch isn’t getting activated by hand, the OH software …

More from the guru :slight_smile: [image] Expire Binding - Not Expiring Bindings events.log does not include Item Updates. But based on the description, it sounds like the Item is being updated once per half hour. It is not unusual for bindings to update Items …

A wild guess. Do you use persistence? Could it be that ‘something’ is updating your timer items? Have a look in the /var/log/openhab/events.log

Depending on the device technology, periodic routine updates may be sent. Updates to same state are not shown in logs.

@BiloxiGeek are you using the Expire binding?

Yes, I’m defining the timer in the expiration metadata.

The switch is z-wave, GE 14292 in-wall toggle switch.

Okay, resurrected my old 2.5 timer into a rules file. Seems to be working as expected. Thanks.

@OMR There is no expire binding in OH3. It is part of the core functionality.

Expiration timer sometimes fails

Permanently powered zwave device make periodic status reports. You won’t be able to use a long ‘expire’ directly, because the periodic update restarts the timing.

[SOLVED] Rules with timers or virtual/dummy switches

OpenHAB 3.1 expire command does not always work
