Disappearing/reappearing device

I’ve got a mystery I hope someone can solve for me. I have a 4 in 1 motion/temp/light/humid sensor (one of 3 such units installed) that is reporting strangely. In my UI 17 the device disappears, leaving only the battery state visible. The space that the unit would normally occupy on the page is there, but nothing shows. When I shrink the room using the “minus” button, the room shrinks to just it’s header. When I use the “plus” button the room opens up to show all the devices, including this problematic one. Then, a moment later the device in question disappears, reverting back to just the battery display.

The unit appears to be working correctly, scenes are triggered by motion.

Is this issue replicating on Firefox?
Have you tried a different web browser, like Chrome?

Hadn’t thought of that. Yup, the device reporting seems to be stable in MS Explorer. So I guess I’ll live with it, seeing as how the device seems to be working correctly.

thanks!
