@IndyMike I want to thank you for your help. After the delete and re-add modules were communicating properly with EISY and didn't have to replace any modules. Was able to successfully re-link with other controllers and add back to programs. Alexa is even cooperating. In a related topic, mentioned at start of post that numerous electronics went bad at the same time. May have been a surge after a local power outage and surge when power came back but don't know for sure, may have been coincidence. One of the devices was my Honeywell Tuxedo Touch keypad. Have that one in the hallway next to the bedroom. Finally got that back online but lost all programming and firmware out of date. Been working on that one along with the Insteon. Good news, Tuxedo has latest firmware and all programing is reentered.

Deleted the model in EISY. Did the factory reset. Turned circuit off at load center, had wife on phone, held the set button while telling wife to turn power back on and continued to hold set button LONG time, no beep. Unplugged PLM for 20 seconds, plugged back in. Did a reboot of the EISY from the Configuration screen. Tried to add Insteon device in link management using auto and it didn't find the device. Tried again manually adding address while linking and it worked. Device is back and responding. ISY-Events-Log.v6.0.4__Tue 2026.05.26 10.57.56 AM.txt

I think we've achieved the point of delete and attempt to add back. I did get a couple devices to respond to EISY commands but there are several remaining such as Jan's lamp (lamp on end table where she reads) that just do not respond. Shows status but no response. See attached screen shot.

In Link Management-Advanced Options I changed from Automatic to Device Reported. Tried to turn on device, adjust on to 100% and write file. Did another Restore Device and then save the Event Log. Latest attached. ISY-Events-Log.v6.0.4__Mon 2026.05.25 06.29.38 PM.txt

@IndyMike Had to look up how to do a level 3 Event log. Think I got it. One of the devices that I can't get to communicate is the Jans Lamp I tried including before. Did another restore for that module (node) and ran the Event Viewer log. What the log has to say is above my normal grade. ISY-Events-Log.v6.0.4__Mon 2026.05.25 05.53.14 PM.txt

I had my first phase coupler back in the days of X10, later replaced that one with the Insteon phase coupler. Still have one or two Insteon Access Points plugged in. Yup, that old. Also had a bunch of Insteon FilterLinc's and X10 FilterLinc Pros. Use to have extensive saltwater reef systems with lots of large pumps and halide lighting so lots of filters. Still have some of the X10 Pro filters still in use but several of the Insteon FilterLinc's died.

Did get a switch and outlet to respond to EISY that previously wasn't responding. Still having issues with the mini remote for the living room that controls the switches and outlets that are having issues. Progress ISY-Events-Log.v6.0.4__Sun 2026.05.24 06.56.04 PM.txt

@oberkc Network Gateway, EISY, Insteon Hub, security system, NAS, Internet gateway, etc are on battery backup and surge protection. All nodes not working are in wall switches and outlets. Dedicated outlet installed next to EISY has been in place for years. Have somewhere around 30+ nodes communicating but six device nodes that are not. Restore Device performed multiple times on each failed device, tried factory reset and add back, still didn't work All this is after the PLM failed and was replaced. I've restored the PLM MULTIPLE times. Most nodes work, some don't. Only thing I haven't tried is to completely delete the modules and try and add back and see if EISY will communicate again. If so, will need to go and redo all the programs and links that include those devices. If not, If this doesn't work, looks like between $400 and $500 in new modules and a bunch of labor replacing and reprograming.

Tried the airgap factory reset on one of the wall switches with the least number of programs attached. Tried the EISY relink, and the EISY add device. Tried to delete that one switch but stopped when it gave a message about removing long list of devices. Figured that might be that that light is included in several programs with other devices. Wasn't sure if it just removed that light from those programs but the way the warning read look like multiple devices would also be deleted so did not delete. Still no communication, rebooted EISY, did another restore PLM with the mini remote in linking mode. Still have six devices with exclamation points and no communication plus the mini remote. Have an Insteon signal bridge hard wired at load center. Everything except the PLM is plugged into battery backup /surge protector. Moving stuff around is not an option. Photo attached.

Tried the "Restore Device" when right click on the offline devices. Does the System Busy for couple minutes while attempting to update and when done, no change. Devices that aren't responding are all hard wire, either wall switches or outlets. Also tried Query Insteon engine. When done get the Failed Communication With error and "Cannot Communicate With (xxxxx) Please check connections"

Every year Portalshark dings my bank account for MobiLinc Connect subscription. I thought that was just part of the portal service subscription but it looks like UD has it's own ap that seems to work. Since migrating to EISY I discovered MobiLinc Pro doesn't work Wondering If I have to delete that ap, reinstall and start over? Also installed MobiLinc X and tried to login in with my MobiLinc account and that doesn't work. Digging a bit deeper it looks like MobiLinc X is a completely different ap and cost $120 per year! Nope. My bank account was just dinged $50 last month for MobiLinc Pro. Anyone with more Insite?

Update: Finally received the new PLM module. Went through the install steps, rebooted the EISY from inside configuration and then did the restore PLM. Now that system can see the PLM again, I have at least six Insteon modules that are now exclamation marks and cannot communicate. These are probably the most used modules. These all worked before the PLM failure. Not sure if I delete the modules and try to add it back again will restore communication and if so, what that does to my programs.

Migrated all my network equipment, cameras, access points and even the phone system to Ubiquity UniFi. Migrated 994i to EISY R2 about six months ago. Anyone know if any of my existing systems will link with EISY? Have the UniFi phone that shows my Protect cameras, Echo Show shows my Ring cameras but have multiple systems that don't talk with each other

Tried again. Unplugged PLM for about an hour, took Golden for a walk. Did the hold black button in while plugging in and it just went solid red and long beep while holding in, went straight to green when released the button. Checked and still get "Not Connected". Did an eisy reboot from the Configuration tab. Checked again, Not Connected and can't do a PLM restore. Ordered my last PLM through Amazon which showed last PLM was February of 2021. Also, Serial does look to be discontinued so that makes the discission for me, ordered the USB PLM plus a male/male USP cable. Slow ship, full week for Prime delivery.

Update: After the reset attempt appeared to fail, I checked the log file. Looks like about 10K log entries which completely stop as of May 01, 11:23 AM. After that date, lines of 0 and null.

Did the reset with the PLM, Unplugged, held for about 30 seconds or so, held the black button while plugging back in. LED went red and about 3 seconds later went green. Unplugged the eisy, same hold unplugged for maybe 30 seconds then plugged back in. Exited out of Administrative Console and reopened, check PLM status and still not connected. Dead PLM? If so, should I reorder another serial or order the USP module this time?
