I replaced my PLM and now none of my Alexa Routines work that trigger Scenes. When I run the scene test all of them fail. I did go ahead and delete and re-create one of the scenes and now it works. I hope I dont have to do this for all of my scenes. My keypad scenes do work when I press the buttons on the keypad.

I'd look at the device tables for the devices in the scenes -- right click and then choose device table under diagnostics. Then use compare button to compare to the iox links table. Use restore device to eliminate discrepancies. Hopefully that will restore communication between devices and PLM and fix the issue.

(This assumes you used Restore Modem (PLM) to accomplish the replacement of the PLM--otherwise first follow instructions for that. )

I checked one device and it shows 6 missing records. So I now need to do a restore device. Correct?

Yes. There is also the "restore devices" command from the File menu that restores all devices but somehow this didn't work entirely for me.

You can check afterward by doing the link table compare again. If the links are still not identical the next step is to do a factory reset on the device and do restore device again. On a KPL keypad the factory reset is to push the airgap button at the bottom and hold until it stops beeping.

I ran the restore and compare on the Keypad and now no errors. I went back and checked the scene and see no changes same errors

Did you check all the devices that your error log says can't be contacted?

I just checked all the devices. One had an issue and I restore it. I then ran the scene test and same result. Thoughts?

Do the scenes run from the admin console or the Eisy-UI? I am not familiar with running scenes from Alexa. There are people usually on the forums who are much more expert than I; perhaps one of these will know what to suggest.

How do you run a scene from the admin console. I dont see the option when I right click the scene. I only see scene test

The scenes still run from the keypads because the keypads have the scene links in them as a controller. So they work without the PLM being in the loop. Presumably ALexa is interacting with the IoX on Eisy, probably via REST, and then the IoX on EISY goes through the PLM to all the devices in the scene to activate the scene. So either the EISY isn't seeing the PLM or the PLM doesn't have the links for the scene responders defined properly. Maybe try following the instructions for restoring the PLM again.

When I click on a scene (not right click) the main part of the page has buttons along the bottom including On OFF FastOff and FastOn. That's what I meant by running the scene from the admin console. Scene test does turn the scene on and then off and reports.

They seem to be running from the keypads. I have done a PLM restore earlier. I thought when I do a table list and then compare any PLM errors would show up. Since there are no errors after doing restore to individual devices I dont understand why all of my scenes fail when I run the scene test. I am not sure how Alexa would work if the scenes all test failed

I thought your problem was that Alexa wasn't causing scenes to tun -- so now I don't understand what is working and what isn't. The device table compare shows what links are in the devices but not what is in the PLM's link table. It sounds like that is where the problem lies. Under Tools in the Admin Console there is a show PLM links table but I wouldn't know how to analyze what's there. (There's no "compare" button.)

Clarification-- there are 3 types of link tables. The IoX keeps a record of the links that are supposed to be in each device and also the links that are supposed to be in the PLM links table. So you did a compare of the IoX "should be" device table with the actual device table, for particular devices. The restore device re-writes the device link table to reflect what's in IoX. I don't think restore device affects what's in the PLM device table (but it might be intended to--I am not an expert).

added clarification

Again my understanding is that scenes will run from keypads with no PLM plugged in. (Unless they need programs on IoX to run properly.). Of course EISY wouldn't know whether they have run or not or have any idea about changes in device status.

The scenes will run from keypad with PLM plugged in. I have never unplugged the PLM. In the ISY admin console when I run the scene diagnostic I get the error saying each device Failed and then link for responder xx xx xx not found. I dont understand what the test is doing. When it says device Failed or link responder not found does that mean it is missing from the PLM or where

I was just saying that the fact that the scenes run from keypads means nothing about the status of the PLM links table. Not suggesting you actually unplug the PLM. You haven't said whether you can turn the scenes on and off from the Admin Console but I assume based on the diagnostic that the answer is no. This means either that the EISY is not communicating with the PLM (the fact that the diagnostic says specific links not found probably means that this is NOT the case. Also the fact that recreating the scene worked suggests that the connection between EISY and PLM is working. ) OR more likely that the PLM does not have the proper links in it to activate the scenes. I would try rerunning the restore PLM procedure following the instructions exactly. Maybe restore the EISY from backup again first. But again others know more than I about all this.

fixed typo

Thanks. I did respond back that I dont see how to run the scenes from the admin console. When I right click a scene I do not see a run button. Where do I find the run scene button. I assume you want to use the procedure for replacing a PLM. I really appreciate your help today.

The on button is on the lower left. If you don't see it increase the width of the window

THanks. I get the same error. I am trying PLM restore now.

No change. Same errors

The ISY/eISY "Scene Test" is basically a worst case "torture test" scenario. In my experience, it's not uncommon for a scene to completely fail the "Scene Test", but work just fine in real life. Also, since getting my eISY a year ago, every one of my scene activations shows "Link responder for aa bb cc not found" for each device in the scene. This message did not appear when using my ISY. Nobody on the forum, that I know of, has been able to explain the message, and since all my scenes work fine, I've never asked UD what it means.

Each of your Insteon devices keeps a list of the devices it will communicate with. One of those devices is the PLM. So when you replace your PLM, it's necessary to tell all of your Insteon devices to replace the ID of your old PLM with the ID of your new PLM. That is what the "Restore PLM" process does. It generates a lot of activity on your powerline, so if the communication with any of your devices is marginal, it's possible the the old PLM ID won't get replaced with the new PLM ID, and in that case, that device will not respond to your new PLM. Also, if you have any battery operated devices, they won't be updated unless they have been put in the SET mode, and unfortunately they only stay in the SET mode for a couple minutes, and the Restore PLM can take longer than that before it gets to the battery operated device.

Once the Restore PLM is done, you should look at a couple things in the Admin Console"

• Tools->Diagnostics->PLM Info/Status: Make note of the xx.xx.xx that appears before the "/ Connected". That is the address of your PLM. It should appear in the Device Links Table of every one of your devices.

• Tools->Diagnostics->Show Device Links Table (can also be found by right-clicking a device->Diagnostics->Show Device Links Table): Every device should have an entry that begins with "A2 00 xx xx xx" and "E2 01 xx xx xx", where xx xx xx is the address of your PLM. If the device belongs to any scenes, it should have entries that begin with "A2 yy xx xx xx" where yy is the scene number and xx xx xx is again the address of your PLM.
