One of my Zooz ZSE40)4-in-1 sensors did not trigger this morning when it should have. When I went to look at the logs I noticed that the label icon next to the sensor was red. I have not been able to find anywhere that describes the meaning of Red vs Green vs Gray icon by the device label. Once I started looking at logs and device info the icon is now green it is working. I have not done anything other than look at logs. Why is the device green and working as compared to this morning when it was red and not working?
