I have a SWL (older version) that wasn’t responding properly. It wouldn’t come on with a scene but would if you told it to separately. I tried airgapping it and factory resetting. Then restoring device in the GUI. Now tonight it’s not really responding and sometimes it ramps up to 100% on its own with no prompt

Is this salvageable or a remove and replace situation?

Just popping in to bump the post to see if anyone has an idea before I just start replacing devices.

If you're saying the device responds to direct on/off commands but doesn't respond as a member of a scene as a responder, the first thing I would check is if the links were created for the scene. You can manually test this by linking the Switchlinc to be controlled by another device like a Switchlinc with no load or a Keypadlinc and assigning it to a button that is not the first button on an 8 button Keypadlinc or one of the four buttons on a 6 button Keypadlinc.

Things seem to have gotten worse. When I turn on the SWL with the app it ramps up and down, it doesn’t respond to voice commands and will only turn on by controlling the paddle of the SWL itself.

How old is it? Possible it's end of life

You have tried the power down and back up reset?

Factory reset and restore?

I have. That’s when the issue seemed to have gotten worse

That’s what I’ve been thinking. I’ll replace it today and see if that doesn’t help.

A few years ago I had the same problem, so I disassembled it to have a look at the internals. There was leakage and corrosion around some of the capacitors, simply a mess.

I just replaced it.

I'm trying to replace what I believe is a faulty SWL with a brand new one.

But I can get into Start Linking because this keeps popping up

If for whatever reason your ISY is stuck in this state, you will just have to power cycle it, even though it says don't do that. There are legit reasons for this message, but they shouldn't persist. So if hours go by and this still happens, you will need a power cycle.

I was going to say the same thing about the caps. For fun I replaced capacitors on some old 2476D's I had and sure enough, they came back to life. For the most part though, it doesn't make a lot of sense repairing them.

Just in case it is a link table issue, it would be easy enough to factory reset it, delete the device from ISY, then add the device back to ISY and re-create all the scenes and stuff. Before you delete it from ISY, take some screen shots of the scenes and stuff so you can quickly put it back as it was. I have had mis-behaving switches in the past where this fixed them.

EDIT: Just to be clear, ISY can have bad/wrong links tables and simply factoring resetting the device and restoring it will just put the same bad links on it. If you delete it and start from scratch, this won't be a problem. I have had this happen a handful of times over the years.

I've replaced the SWL and it seems to be working. I'll post back in a few days to confirm the issue is solved.

Thank you all for the help as always.

One thing I’ve noticed is the light doesn’t change when I tell Alexa to change the scene

(Ex “turn on Livingroom 30% changes all other lights except the newly replaced swl)

What have I forgotten to do?

You might have to go to Alexa and say "Discover devices".

If that doesn't do it, you might have to remove the device and any related scenes from Alexa, re-add them, and say "Discover devices"

I'm going to assume that you have a scene and that in the portal you set the scene to be controlled by Alexa (not individual devices).

Since Alexa still is controlling the scene, it sounds to me like the new switch isn't in the scene. If you did a "replace with", then it should be in the same scenes as before. If you deleted the old device and added the new switch, then perhaps you never put it into the scene.

I used the GUI to ‘replace’ and it’s in the scenes in the gui as it should.

I’ll try that.

If Alexa is controlling the scene, then Alexa won't know if you swapped out a device in the scene. Alexa doesn't see the individual devices in a scene. Alexa triggers ISY to issue a "scene on" and from there it is all Insteon configuration as to what responds to the scene.

What happens if you trigger the scene from the ISY admin console? If that works, then I can't understand how Alexa isn't unless Alexa isn't triggering a scene but rather a device.

When you open the ISY portal and go to Amazon echo:

Is the "ISY category" for whatever it is listed as a "scene" or "device"?

They are all listed as scenes

When I trigger the scene in the GUI the GUI says the light changed but in reality it hasnt

Also, this keeps opening when I open the GUI

So the problem is with ISY, not Alexa. If the light doesn't turn on when you turn the scene on from the ISY admin console it isn't going to turn on when Alexa triggers it either.

I have also had this (edit, by this I mean it keeps doing the pop up) happen after adding a device and ended up having to power cycle ISY. A bug in one of the more recent firmwares I guess. I have now seen at least a couple other people report this.

I would start with rebooting your ISY (eisy/polisy/whatever model). Then see if the scene works. My bet, however, is it will not. Perhaps the "replace with" command did not function correctly. You can always try a "restore device", but I usually just completely delete the device, add it back, and configure it back into all the scenes.

Just a little clarity. True that if the ISY can't turn it on, neither can Alexa.

If you use the ISY to turn an individual device on, the ISY get's a confirmation from the device indicates on or gives an error.

Scene members don't confirm they've received the message. When you activate a scene from the ISY, it's fire-and-forget.. and the ISY assumes its on and indicates that.

It could be the switch, the scene or noise problem, but I think you might have eliminated one or more of them.

• Go to tools / diagnostics / Event Manager and set it to level 3 at the bottom

• Fire off the scene

• Turn that specific device on directly

• post back the results

This indicates the scene isn't programmed correctly for IoX to be the controller. You might need to rebuild the scene or change the settings for IoX to control the scene the way you want it to.

You might want to open a support ticket with UD on this one. Seems like you added a device and it might not have completed accurately. You might need to remove it, reset the device, and add it again. But support might be able to give you other troubleshooting tips.

I have had this same problem after adding a device. It did add the device, and the device worked properly, but the popup just keeps happening every time I opened a new admin console session. After rebooting eisy it stopped. I feel like it is a firmware bug. I have added multiple devices and it didn't happen every time. I never saw this problem in the 15 plus years I have had an ISY until just a few months ago.

Regarding the OP's issue. I think the scene is corrupted. I would delete the device completely from ISY, factory reset it, add the device back into ISY, and then put it back into the various scenes. Hopefully it isn't a super complicated set of scenes/programs.

Restore Device did the trick it seems.
