you don’t really need to log every state change in your events.log. You can lower the log level for this type of entry
either via openHAB console:
log:set WARN smarthome.event.ItemStateChangedEvent
or from the log config file: see example here: Log4j2 Sample Config
Notes:
- By default, this log category is at INFO level, so it’s normal that you are getting these entries logged
- It’s not binding specific. All item state changes will be logged, independent of binding config
- As mentioned above, you should increase the NTP interval. 60 secs is too small
