Showing online wanted messages in the logbook

Hi,I want to see only the message “motion detected” and not the messeage “no motion detected” in the logbook. How is this possible?

Zigbee Bewegungssensor

Could you do something with custom logbook entries for motion detected using the logbook.log service?

Another idea:

Write an automation which is triggered by motion detection (if you haven’t got one already) and log that.
