Hey @ryan.mercer - It was definitely the PLM. Everything has worked perfectly since getting it repaired.

Hey everyone! Finally have an update on this... It was the PLM on the fritz after all. I purchased a used one on eBay and it arrived DOA. After some negotiation with the seller, I got a partial refund and then sent it off for repairs. Got the repaired unit back yesterday and swapped it in this morning, and everything seems to be working reliably now! 🎉 Thanks for all the help! 🙏

Yup. I also upgraded from 4.x to 5.x at the same time (since that was necessary for ISY Portal/Alexa). Thinking back, I hadn't yet unplugged the Hub at that time, and I did find that Alexa was only intermittently able to control devices. I didn't think much of it until we realized our regular evening programs (turning on a few lights) were not running consistently either (more accurately: I think they were running but not actually getting the lights to turn on). And then when the new Insteon owners sent out an email saying that the servers were back on, I started to think that maybe the two Alexa skills (one for the hub, one for the ISY) were competing with each other, and that's when I unplugged the Hub. So, the problems definitely were happening before unplugging the hub the first time. Anyway -- I've started emailing with Michel, and I will work through whatever he says to do... and will also try running that Topology this weekend and see how it goes. Thanks again, and hopefully I'll have something new to report soon. Have a great weekend!

Buuuuut.... I've plugged the hub back in (and it has a green light) and the issues remain (and are getting worse). ? I barely used the hub for anything, too. Really I used it only for Amazon Alexa. ?‍♂️

Hi Geddy, thanks for following up. It's still problematic; I haven't updated here because I ran out of ideas.. ? We've also started to see some other weirdness when programs run -- which is making me think that the PLM may actually be on its way out. Last night, at 9:49pm a program correctly ran on the ISY that should have turned off a single dimmer. Instead, all but one one dimmer in the house turned off (there were at least 3 or 4 that were on at the time, and should not have changed). Definitely not normal! Yes, I set up all my devices long before I had the ISY, using the old-school manual device-to-device linking method. But, that has all worked just fine for like 9+ years. And now, devices that are linked directly still work and communicate perfectly with each other. It's only ISY/PLM <--> Insteon communication where there are issues. Did that shortly after upgrading. I did have some problems after the upgrade, because I was using version 4.x of the admin console without realizing there was a new launcher. So I had the 4.x admin console and the 5.3.4 firmware... and things were running really poorly or not loading. I also had accessed the admin console with an https:// URL and it was super-super-slow. Once I changed to the new launcher, and used an http:// URL, the admin interface worked just fine... but while troubleshooting that, I did increase the Java memory. But may be my admin mismatch caused some issues with the ISY? Yep, I agree, and will do. I think at this point I need to figure out if the PLM is dying, as the erratic behavior is starting to make me think that's sadly maybe the case. Hoping the new Insteon owners can get production of new units up and running soon! (Or maybe I'll have this person refurb mine?) I also wonder if I should try rolling back the ISY to version 4.x (if that's even possible?) and/or doing the full reset on the PLM? But I'll see what support suggestions. Thanks again - I'll definitely post back here if I have any updates.

Just to confirm the links tables, I did a "Show PLM Links Table" again and got 141 links (same as before): I then tried doing a "Show Device Links Table" for the Kitchen Ceiling dimmer and it went through for a bit and then failed... maybe this error is informative? I tried doing another "Restore" for the Kitchen Ceiling dimmer and it choked again: However I've been able to get a couple of other devices to complete the "Restore" process successfully... Though I don't think that's likely to actually help. I also then tried to get the Device Links Table to compare to what the ISY has on file, and I was able to read some devices, but not others. I would think that if this was an issue with "dead" or "orphaned" links I shouldn't be seeing these kinds of communication issues?

Oh, no, that's not the case. The hub is currently plugged in and things are still not working properly. It's just that I was able to complete the "restore" process on one device successfully, once... but with intermittent signals/responses I think that was actually more of a lucky fluke than anything else. ? When I am in the ISY interface and view details for one of my devices, and then click "On" or "Off", sometimes it works but only about 25% of the time. Other times I can see the ISY sends the command and nothing happens. As far as I know, the Hub didn't actually "do" anything with linking and the ISY. It's been many years so I don't recall for sure. I don't think I factory reset them though, I probably just linked them in the Admin console. Ah, yes, we did do a link count (also eaten by the forum). Got a consistent 141 links on each of three runs. ?‍♂️ I just unplugged the Hub, and then successfully turned the Kitchen lights on via the "On" button on the ISY Admin panel. Here's the event log for that one action: I then clicked "Off" and it didn't work, and this is the only thing in the log: I then kept trying (and also tried a "Fast Off")...and after a number of additional tries they actually turned off: I did just recall, that I had to replace my PLM a few years ago. At the time, I think I followed the procedure for the "Restore PLM"... and I vaguely remember some notice about the ideal way to do it was to factory reset every device as well, and I didn't want to go down that road (I have quite a few!). So maybe there are old/dead links to my old/dead PLM that's no longer around? I don't know why that would suddenly be an issue after upgrading to 5.x but maybe there's something to that? Or, maybe my PLM really is just on the fritz and it's a dumb coincidence? ?

I don't think that's the case? I think everything was actually linked to the PLM. How can I verify this?

Thanks @Geddy. I was able to "restore" one specific device, but I think I just got lucky. I tried restoring another device (twice) and could not get the restoration process to complete successfully. I've since plugged the Insteon Hub back into the wall, so my hardware setup is now exactly the same as it was before I upgraded the ISY to 5.3.4. And to be clear, the links on devices themselves are working just fine -- all my KeypadLincs, for example, talk to other switches just as reliably as before. So there are no communication hiccups or glitches when it's from device-to-device. The problems are only when the ISY tries to communicate (via the PLM) to devices. So... I'm confused as to why the Hub would be an issue?

No new electrical devices... can't think of any recent changes that might interfere with the Insteon signal (and, devices can communicate directly with each other without any issues). I've rebooted the ISY and PLM a couple of times, but can certainly try again! If I'm going to factory reset the PLM and then restore it, are there any pitfalls to watch out for? The instructions here seem to pertain to replacing a PLM with a new one, rather than a factory reset and then restoring the same hardware. ... so I just want to be sure this won't make anything worse! https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:File_Menu#Replace_Modem_.28PLM.29 Thanks again!

I turned off automatic updates to battery devices. The kitchen sink and kitchen ceiling, which I've been working on above, are both hardwired dimmers. The light on the PLM is solid green, yep.

Oh, hey, just tried it again and it worked! Not sure if that's just because I got lucky and one of the intermittent failures didn't happen? Here's the activity log in case it's useful?

I did try to restore devices and it ultimately failed. Now my ISY is showing all of the devices have pending updates with the "1011" icon: So I just right-clicked on "Kitchen Sink" and selected "Restore Device."... and this is all that happened: So then I did a "Write Updates to Device"... It popped open the status window and ran a bunch of commands -- and then when it got to about 99% it gave me a "Cannot communicate..." error again.

Hi @Techman, thanks for jumping in here. (A couple of other folks chimed in over the weekend, but I guess there was a forum crash and those got lost? Finally able to get back on to reply!) I had used the Insteon Hub to integrate with Amazon Echo - that's basically it. All my other programming was done through the ISY. When Insteon died, I learned that ISY could now integrate with Alexa, so I upgraded it to be able to use that instead. So the only physical change to my system was that I had unplugged the Insteon Hub (since it was useless). This weekend I plugged it back in, but that hasn't made any improvement. My PLM is a 2413S v2.2 1629. I have unplugged it and plugged it back in, but have not done a factory reset on it. I know it's common for old PLMs to start failing, but since it was working perfectly before upgrading to 5.x I'm skeptical that this is the actual issue. (I'd buy a new PLM just to be sure, but of course that's not an option at the moment...) Some of the switches are 8+ years old, however, (1) I've never had this "All On" issue before, and (2) All Insteon switches (and the mini-remote) are communicating just fine with each other. The only communication issues are when the ISY tries to trigger something. Not sure if this helps, but: If I view a specific device in the ISY control panel, with the Event Viewer open, and then click "On" or "Off" and the device does not respond, I will see only one logged entry, like so: If the device actually responds, the log entry will look like this: Seems like the next steps are probably to reset some devices and try rebuilding links? I'm unclear on the best way to do that -- I find the UD docs quite confusing and I don't want to go out of order and make anything worse! Thanks again!

Ok, so after I posted this I realized I could try resetting all devices: https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:File_Menu#Restore_Devices I have the Event Viewer window open and, near the start of the process, it tried to reset the PLM and then said it could not reset the PLM: It's now proceeding through all the devices and I've gotten a number of popups saying that it "Cannot communicate with X device. Please check connections". Considering I've never had any communication issues in the past (and I haven't made any physical changes at all), this seems quite odd. It just finished after about 30 minutes, and although there was lots of traffic in the event viewer, it seems that none of my devices were successfully updated: I saved the event viewer log - happy to share if that might be helpful?
