So, I noticed the same thing as @Spinny did (he mentioned it in the v5.5 thread…SmartTiles Dashboard v5.5: Added UK 
, 5 × Dashboards, and more! Nov 6, 2015 ) about the multisensor open/close events not showing today in the SmartTiles event history. Yesterday they showed. I have both vibration/acceleration & contact set in my dashboard. In fact, I have all four multisensor tiles on my dashboard. The contact sensor tile shows open and closed when applicable on the SmartTiles dashboard itself, it just doesn’t register in the event history. Also as @Spinny stated, the open/close events show when you look at the sensor’s recent activity directly. The temperature and vibration events are shown in SmartTiles history, just not the open/close events.
My log level is set to INFO. I tried the other four options as well, but nothing changed.
