Lights switch on at random times

[jlloyd_UD]

I upgraded my ISY994ir to an eisy several weeks ago, and after some minor problems, I finally got my Insteon devices and programs reinstalled, along with my Alexa "spokens."  For the past several weeks, everything worked as it had before the upgrade without any glitches..  Yesterday evening, many, if not all, of my lights were randomly switching on with no command, either by voice or through a program.  The lights were switching on in the middle of the night without explanation.  I rebooted the eisy (power off and on), and that did not change the behavior.  What should I look at to see what might be triggering this unwanted activity?  I have just upgraded my subscriptions to Alexa (new voices and more conversational), but I do not think that is the trigger, although it was a coincidental change I made and the random light switching followed soon after.  I ask Alexa to switch the lights off and she is able to do that.  Does the Amazon change possibly create a trigger signal somehow?  I am using IOX version 5.9.1 of the eisy and have a serial PLM, and my Internet is disabled.

Take a look at this article

INSTEON Random All On Events - Universal Devices, Inc. Wiki

You should also do an "upgrade packages" on your eisy which will update you to 6.0.0 and contains substantial upgrades/improvements over your current firmware.

Techman, I upgraded my eisy to version 6.0.0. I had been meaning to do that, and your prompt caused me to get it done.  Thanks. After upgrading, the random light behavior remains. I had hoped it would solve the unexplained behavior.  I read the article and, to the extent I understand its content, I am not thinking this is a source for my problem.  This is not an "all lights on" situation.  This is individual lights that come on at unexpected times (middle of the night, for example) when there should be no events that trigger the behavior. So far, there have been no instances where more than one light switches on at a time, and, therefore, these events appear to be independent. When I look at the log I can see where the light switches to an "on" state but there is no indication why it changes its state from "off." What else might I investigate?

Is there any pattern to it? Like the same light coming on at the same time? Do any of your programs have time triggered events?

How old is your PLM? An older PLM nearing end-of-life is a possible explanation. If you don't know, there's a white sticker on the back with 4 numbers on it. What are those numbers?

paulbates, my dual band PLM is Model 2413S revision 2.4, 2817

Guy Lavoie, I have several programs that are triggered by sunrise and sunset times and are typically offset by minutes.  But the lights affected also include lights that are not in programs.  I have not determined that there is any pattern involved.  Some lights are also linked by several Insteon switches, but some are commanded only by one switch

Ok. That means it was manufactured in the 28th week of 2017 and making it 8 years old. There's a time around then when Insteon remedied a problem with capacitors that caused the early demise of PLMs, I don't know exactly when so it's candidly tough to call it as the root cause to  me. 

I would still say it's likely

Here's some more steps

• In iox. Go to tools / diagnostics / PLM info. What does it say?
• Report that back
• There's another step but it comes after hearing what the first step reports

If you're seeing the on command for the light(s) in your log then it's most likely not connected to an all on event.  I would focus on a program that's probably turning on the light(s)

Take a look at your program summary tab to see if a program ran at the same time your light(s) turned on.

It's also possible that the link tables for the light(s) got corrupted. Try doing a factory reset on the light(s) then a restore device

paulbates, I am attaching a snip of the information for my serial PLM.

I just had one of my lights illuminate and looked at the program summary tab.  Of the 8 programs I have that are enabled, all were idle at the time the light was switched on.  I will, at some point, perform a factory reset and restore in case the link tables are corrupted.  This situation affects at least 7 lights, and I am still thinking the events are independent.

The next step is suggest is a restore modem / plm from the file menu in iox. If that works, it's likely a bad plm on the the way to failure.

Let's see if it does help. Again, if it does help, it is not all set, this is a symptom of a dying plm

If it doesn't work, now much lost including time.

I just did a restore PLM command.  It paused and then displayed a bar that counted up to 2% before disappearing.  Is that a normal response to a restore plm command?  I have been waiting to see if the random lights illuminate again. So far, none have after 5 minutes. I will report back if this has temorarily resolved a failing PLM.

Just after I responded, a light illuminated, so maybe the restore step either did not properly function or it made no difference.

or, the PLM is having difficulties and the restore prompted it. Hard to say. 

Have there been any power surges that you know of, or brown outs blackouts recently?

Another test of the PLM, which will affect programs, is to unplug it and wait for the problem to reappear... but if anything critical is handled by your iox programs then DON'T do this test.

V2.4 has the later capacitors and new serial port board. Including the better serial port interface chip and protection on the two serial interface signals.

I really do not have anything critical especially during the overnight hours.  I will disconnect it when I go to bed tonight. If I do not have lights coming on when I unplug it, does that mean it is isolated as a problem emanating in the PLM?

I have whole house surge protection and have not had any weather-related surges that I know of.  I have a Ting power quality monitor and no surges have appeared before Monday last week.  I will get a weekly summary tomorrow that will identify any power surges for any reason that have happened in the past week.

I guess that is an indication that my PLM was an improved version, but does not guarantee that it is not failing due to advanced age.  Thanks for the information, Brian.

[paulbates]

Brian would know that answer for sure. It looks like the plm as a problem is a dead end, unless you find no other solution.
