@Brian H Revision 2.6 1223 on the PLM. I replaced this one with a new one with the same revision and date code... what a nightmare.. more to follow! And nothing at all has been changed or added in the last year. The status quo remains on all of that stuff. I can think of nothing new, added or plugged in, but I am starting to think that maybe something is creating noise or it is coming in from the lines or I have a faulty eISY, like the USB chip or driver got flakey.
Last night after physically replacing the modem, plugging it in and plugging in the eISY, it was doing a query. That query ended up with nothing being found of course. When complete, I did a File>Restore Modem (PLM), (which I have had to do in the far past), and nothing seemed to be found... a few nodes were found and updated, however the rest were Failed Communication. The dreaded red exclamation mark. Being frustrated beyond all belief and wanting to just chuck everything, I walked away. About 10PM, I started to click and query each device one at a time. About half of my devices or nodes responded with the green Write Update to Device icon and I was able to individually update each device. HOWEVER, there were a few that after showing up and working just lost communication and the red exclamation mark reappeared. Then I could not get a positive query of other devices for some time. I tried to note the HVAC fan motor or anything else that might be running but nothing was. After letting things sit again for a few minutes, I was able to continue my manual query and write updates. There were a few that I had to Restore Device but by the time I went to bed everything was found and seemed to be working. When the HVAC came on everything was still alive and I just have no idea what if anything is making noise. I have to admit, I am looking at something flakey with the the eISY and figure it might be to my advantage to put in a ticket and pay whatever to try and find a fault somewhere in the eISY or at least where to start looking. At the time of this writing, 1030 AM MST, everything still seems to be working.
In hindsight, (I have two locations and two eISY's), this one that I am having problems with did give me an issue with Notifications running but not connected during the big upgrade, which reinstalling the plugin twice, fixed, but I have had other issues with this one in the past. Especially after updates. I am not pointing the finger to the recent updates as it has worked great since that time, but something weird was going on and I have no idea on where to start sniffing. Now, I am wondering if this latest "fix" will stick or what may happen next but I will report back.
Thanks!
