Thanks, I'll give it a look and report back. I am dreading replacement of the ISY and all the other stuff I would need. Looks like ~$500 in my case (EISY, Z-Wave module, PLM), unless I can reuse my serial PLM (and it is not the culprit).

For the past week or two my ISY has been rebooting repeatedly. It works OK when it has finished but (obviously) doesn't while it is restarting and polls some 75-80 IoT devices in my home network. It worked perfectly for several years until now. UD Mobile and Alexa connectivity is hit and miss too. Yes, my portal subscription is up to date. I have tried shutting off Email notifications, and stopped polling the ISY's API with some Arduino software I wrote - this did not help. I do have a Z-Wave module installed in the ISY. Any ideas on what could be the cause or has anyone had a similar experience?

I am using an IOLinc to control and monitor my garage door. The problem is when the magnet moves close to the reed switch it closes and opens the sensor circuit a couple times before finally turning "on". I can see the green light on the IOLinc stutter a couple times before going solid, indicating a closed door. The stuttering is probably due to vibrations as the door closes - it is a heavy, hurricane-proof door and weighs a ton. The problem is that the IOLinc sensor sends 3-5 open/close messages to the ISY before stabilizing. This fires my door-status program multiple times in the ISY, sending numerous false SMS messages to my phone. The last SMS is correct, but it is driving me nuts. Does anyone have any clever programming tricks to inhibit the sensor-status program from firing multiple times? I do need it to fire once when the stuttering is over. I also need the sensor program to fire reliably if someone pushes the legacy garage wall opener-button or uses the car-remote.

I tried all of the suggestions in this thread, and still can't get NTP to work. I get endless DNS errors and my clock drifts. I do have my ISY-994i on port 443/SSL and can communicate successfully with it from my LAN and WAN. My log is full of 60006 errors. I updated to firmware v4.2.7 - no help. Any ideas? I attached a screen shot of the admin console.
