Sensors going Offline
I have whole groups of entry sensors going offline. In the 'devices' web page, I have tried removing and then reinstalling them. The issue is that now, other sensors show as offline. I went through the exercise 2 or 3 times, and every time another sensor or group of sensors is offline. Making the issue worse is the fact that the SAVE button hangs for minutes or longer, and I ended up having to reload the page in the browser.
So far, I have not been able to resolve this.
