I have three pi’s that I use to monitor temperatures in three buildings using DS18B20 sensors. Two of the installations are completely trouble free and the third keeps dropping the connection to myDevices. Usually a simple power cycle of the pi restores the connection. Sometimes it may go a week, other times only an hour or two. All are wifi connected to the internet, the troublesome one likely has the weakest connection. The troublesome one is also a pi2 whereas the other two are pi3’s. Today, the situation is a little different. The troublesome pi shows that it is on line in both the web interface and in the Cayenne App but the widgets show 0% and the temperature is stuck at 62.04F. If I try rebooting remotely nothing happens. It is like the pi is offline but indications are that it is on line.
Does anyone have any idea regarding trouble shooting this problem? Thanks in advance.
