I3 Switch Setting - Relay at Full On?
I don't have an EISY, but I'm guessing the feature relates to the following: https://www.insteon.com/simple/#Manually-change-switch-modes-dimmer-or-on/off-mode

Motion Sensor Only Works in Scenes, not Programs
I don't have a good answer to your question on how to determine PLM link record #'s. Earlier posts suggested putting the PLM on a filterlinc to "reduce" insteon communication (https://forum.universal-devices.com/topic/6979-countingestimating-plm-links/#findComment-55359). I've actually had limited success with that - probably due to RF communication. As far as reducing the link count - have a look at your large scenes to see if you have redundancies. Unfortunately, if you can't get a good link count, you won't know how many links to delete. Thanks for the Aeotec info.

Motion Sensor Only Works in Scenes, not Programs
Not quite. The ISY knows the address of the dimmer module - it sends that address to the PLM so it can communicate with the device. If you are over the link limit, the PLM will not be able to find the address of the dimmer. If you manually activate the dimmer, the PLM will ignore the communication (just as it is doing with the MS). The Z-wave motion will circumvent the problem for the time being. No telling how many devices/links you have that are beyond the magic #. Which Z-wave motion are you using? I'm always on the lookout for reliable motion sensors.

Motion Sensor Only Works in Scenes, not Programs
Sounds like you stepped over the magic line again. I find it is best to run the PLM test in the early AM when the rest of the house is asleep. Two consecutive tests with the same # of links is considered a good test. You could also try performing a "restore modem". In doing this the ISY may be able to recover link records by consolidating memory from deleted devices and scenes. Perform a ISY backup first to be safe. I just performed this on my PLM and was able to recover 150 records (I do a lot of adding/deleting during testing).

Motion Sensor Only Works in Scenes, not Programs
#4 - sounds like you ISY (EISY) is being interrupted during the PLM record read. You may want to try in "off" hours. I was asking you to "trigger the motion sensor" (create motion) to see if the PLM registered the communication. Since you did NOT see any communication in the event viewer, you are NOT receiving the signal from the motion sensor. Either your PLM is outside the RF/powerline range of the motion sensor (unlikely since your just re-added the sensor), ...or the PLM does not have the correct link records to receive the communication. Normally, that would imply that you have exceeded the PLM link record capability (~1000 links).
-
Motion Sensor Only Works in Scenes, not Programs
That should work. If it doesn't your PLM isn't hearing the Motion Sensor or has lost the link for it. Open the Event viewer and trigger the motion sensor to see if the PLM is registering the communication. You should also see the program executing your "study cans on" command. Please post the results. Other options: Make sure your program folder isn't disabled. Power cycle the PLM and ISY. Check the number of links in your PLM (max 1000)

Why did I have to recreate my scene?
I missed the fact that you located an incorrect INIT value... Beyond that, I'll admit that the scene adjust method produces elegant results. I personally don't care for the overhead involved. In terms of the write cycles involved, you probably will not wear out the EEprom before something else dies (power supply, etc). Most EEprom devices are rated at 100,000 cycles. At 2 writes (AM/PM) per memory location per day your device EEprom would last 137 years. Sorry - I should have used my Maths before my previous post. The raw amount of communication required is a concern. Communication errors could result in corrupted device link tables and scene errors. You can check this by performing a link table "compare" from the admin console. You can use a time qualified program to call a scene and produce similar results. Use the scene controllers as the program triggers. My example scene above would look like the following. Note that I inserted a second wait After the Trigger and before calling the Scene - This is because the trigger (BSMT Stair) is part of the Scene (BSMT ENTRY). Best practices call for the wait to prevent potential communication collisions at the PLM which can in turn trigger the dreaded "ALL ON" phenomena. The event viewer communication for the command is shown at the end.

Why did I have to recreate my scene?
Wow, that's a lot of updating for day/night on levels. I'll confess that I've never really used the "Adjust Scene" program feature. I prefer to generate specific scenes for different levels and call them through a program. I'll admit that what you are trying to do would result in an "elegant" changeover in device on levels. The price you pay is an extreme amount of communication and many writes to device and PLM EEprom memory. The high communication level opens the door for errors. Excessive EEprom writes can actually wear out the memory devices. You also need to be very careful that you are writing to ALL the scene controllers as well as the Admin Console scene (in case the scene is called by a program). At a minimum, you should insert some wait statements to allow the link table writes to complete. Based on what I'm seeing with PLM write timing, the wait should be around 5 seconds. Try opening the Event Viewer (level 3) and manually running your program. You'll be amazed how much communication results. I tried adjusting 1 scene with 1 controller - the program and Event viewer communication are shown below. You will have MANY times this amount of communication. Answering "Why did I have to Re-create my Scene" - Communication errors during link table writes - or - Worn out EEprom memory (PLM or Devices). Hopefully it's #1.

Issues after installing Tesla powerwall 3
I have been unable to locate any specifications on the RPC1508-64. I did find the following Enphase filtering document that recommends the use of a RP240-80-10-S for noise issues (https://enphase.com/sites/default/files/2021-06/Power_Line_Filter_Single-Phase_TechBrief.pdf). This device is available @Newark for $233 (https://www.newark.com/astrodyne-tdi/rp240-80-10-s/filter-1-phase-80a-250v-chassis/dp/85AJ1317). Specification lists insertion loss (filtering) @150Khz of 40/60 db for CM/DM signals (https://www.farnell.com/datasheets/3622987.pdf). ...not much of a specification. The Enphase document indicates that it's Microinverters communicate over the powerline @144Khz. The filter is used to clean (or isolate) power to allow the communication. I would not have purchased this filter expecting it to filter/isolate noise in the 130Khz Insteon communication range. While the current range is applicable, the filtering range is spec'd from 150K up to 30M. Too expensive to roll the dice hoping that a device spec'd for 150Khz and above can filter sufficiently in the 130Khz range. Based on the results that @NCSTATE78 is seeing, the filter has sufficient bandpass to cover the Insteon range as well - at lease for the RPC1508-64. Just another data point. NOT proposing that anyone try this. It COULD be something to mention to your installer.

Higher Voltage Options for Insteon 6-Button Keypad?
OK, 277 volts would correspond to a 480V 3-phase installation (277V is one leg of the 480V 3-phase). That is truly a commercial install. If you are trying to communicate with devices on all 3-phases you will need RF coupling devices on all 3-phases. That's a different topic, but mandatory for 3-phase (passive coupling will NOT work). The SKU you provided led to the following specification: https://www.ali-corp.com/Upload/File/f184035e-11c7-4c50-92ae-1d016b64d611/Linear Strip-1,.pdf Your lamps can be powered by by voltages ranging from 120V to 277V. Unfortunately, the specification indicates that they must be dimmed by a separate 0 - 10V signal. If this is the correct specification, you should NOT use a Insteon Dimmer with these lamps. The lamps were designed for a dedicated switch (or relay device) to supply power, and a separate 0 - 10V dimmer. Insteon does make a 0-10V dimmer, but it installs at the device and is controlled via RF (https://www.insteon.com/0-10v-ballast-dimmer). I have never used one of these. It is rated for 277V, but I am not certain that it is appropriate for a commercial installation. You would obviously need a separate RF controller for the dimming function.

Issues after installing Tesla powerwall 3
@NCSTATE78, excellent data point - thanks for sharing. Sounds like Tesla is coming up the learning curve on how to avoid powerline communication problems. Not an easy task. The Enphase filter certainly has to power rating (64A) to handle the Powerwall. There are unfortunately not many specifications on load isolation and filtering. Usage and installation is include in the following (LONG) document: https://enphase.com/download/planning-enphase-energy-system-tech-brief If someone has the technical specification on the device itself, I'd be all ears.

Higher Voltage Options for Insteon 6-Button Keypad?
It sounds like you are using a Insteon 2334-232 Dimmer as the controller for your garage lights. I'm guessing this because a dimmer will get hot when overloaded whereas a Relay (On/Off) switch will simply erode (or weld) the contacts and stop functioning. The specification for the 2334-232 is 600W incandescent or 150W LED (https://shop.insteon.com/products/dimmer-keypad-6-button). If you truly have 600W of LED load on the circuit, you are way over it's rating. It's not the easiest to find the LED ratings for these devices, but I'm surprised that your electrician didn't look harder. It's incumbent on him to ensure that the installation is safe. The 227V (??) rating is likely the "maximum" voltage the where fixture will operate safely. LED fixtures incorporate internal power converters that will often handle between 120 and 277V. Your 2334-232 is actually specified to operate over 120 to 277V. If you are in the us, you are using plain Jane 120V/60Hz The normal device used for a high wattage installation like this would be an On/Off switch (as @paulbates indicated). I actually have a similar installation in my garage that consumes 432W and I am using a 2477S. The Manual for the 2477S does not have a separate specification for "LED load". It simply specifies "1800 Watts" and I am well within that - ignorance is bliss. The current 6-button KPL On/Off switch is unfortunately nor rated for 600W either (https://shop.insteon.com/products/insteon-remote-control-on-off-keypad-6-button) The webpage shows 450W Led load maximum. Not sure how to interpret that since it likely uses the same relay that is in my 2477S switch (should have the same ratings). If you can provide some additional information on the Make/Model/quantity of fixtures you are using, that would be helpful.

Ghost links
@SirParadox , your device B isn't capable of "pushing back" a link to device A. The only way for device B to write links in device A would be if you Manually linked the device. If that were to happen, the ISY would have no record of the links (it would show up as a mis-match) and you could easilly restore the device. If you believe the link tables in both devices are incorrect, you will need to delete, factory reset, and re-add both devices.
-
Ghost links
@SirParadox, the device 3D.96.1C appears to be a PLM. It is listed as a controller for group 0 of your family room overhead device. It is possible that this is an OLD PLM (check your current PLM address to verify). In any case, the ISY believes the links to be correct. Restoring this device from the ISY will simply re-write the same links. If you are sure that the links are incorrect, the quickest way to rectify is to proceed as @apostolakisl indicated in his Option #2 above (delete device, factory reset, re-add to the ISY).
-
PLM Links Table question
@Tmc, I'm in agreement with @paulbates. Since it appears that you have having problems communicating with numerous devices, it's likely you have a noise source or signal absorber near the PLM location. Look for PC's, chargers, printers, UPS's that are common culprits, and remember that electrical devices do go bad. Another option could be your phase coupling. It's interesting that your system was working with the 2412S which is not dual band. The 2413S is dual band and would presumably perform better in a noise environment. How were your phases coupled before? Note that the 4 tap test (beacon test) that Paul suggested is an excellent way to detect phase issues.

Add Hue bulbs directly to the eisy, partial success.

ERV Air Testing Routine - Improvement Suggestions
@pjjameso, your timer program is marked "Run at startup". Can you see it running in the "program summary tab" (you've probably already looked). If not, try a manual start (Run Then) to see if things run and continue. If everything looks good with the timer program, try re-writing and saving the "Airthings AQ Normal" program. I have seen instances where the "text" of a program is correct, but the saved XML is not. A simple Edit/Save will not correct this.

New PLM. EISY can transmit but does not receive.
@AD8BC, as you probably already realize, your PLM is only linked to 4 devices. Something is seriously wrong with the restore. If you have a recent backup, try restoring the EISY then follow with a PLM replace procedure (EISY needs a reboot to recognize the New PLM).

PLM Links Table question
@Tmc, sorry for the delay in responding - I was on the road. Answers: I "save" the PLM table as an XML file and then Import to Excel as an XML table. it allows be to sort columns and select individual device addresses for inspection. Unfortunately the values in the XML file are in decimal. You have to convert to Hex (+dec2hex) for them to make sense. Curious - my file save with an .XML extension. Most browsers can open it and it appears as you have shown above. In order to format the data, you can open the file with Excel or use a XML viewer. The link 325 that is shown is a "responder" link. As I indicated earlier, I believe the ISY leaves these. As @Techman indicated, the PLM link read isn't perfect and can be interrupted. I run the process 2 - 3 times in a row to make sure things are consistent.

PLM Problem? Uncommanded ON for multiple devices
@walkman9999, Had the chance to look at the files you up loaded. Your _Northgate program has a lot going on. Many Device Direct Fast ON commands in succession, followed by a scene command, and then more Direct commands. The rapid succession of these commands are bombarding the PLM and may be confusing it. In my experience, the PLM is rather good at handling stacked commands (back to back). But then I use the older ISY994. The EISY is far faster, and may be capable of overwhelming the PLM. I've posted a section of your event viewer below the program listing. Your fist Insteon command is a Fast ON to device 29.18.D7 Highlighted yellow). The normal sequence would be: Wed 02/12/2025 16:46:26 : [INST-TX-I1 ] 02 62 29 18 D7 0F 12 00 (Fast on Command to PLM) Wed 02/12/2025 16:46:26 : [INST-ACK ] 02 62 29.18.D7 0F 12 00 06 LTON-F (00) (Acknowledge from the PLM) Wed 02/12/2025 16:46:26 : [INST-SRX ] 02 50 29.18.D7 71.1B.41 2B 12 00 LTON-F (00) (Acknowledge from the device) I've highlighted all 3 in the event viewer listing below. These would normally be in sequence. As you can see, you have many other commands in between, as well as the curious "Link for responder XX.XX.XX not found". I believe this is the PLM informing the ISY that it doesn't contain the link for these devices. The thing is, I looked at your PLM listing and it most certainly does contain the links for these devices. As I said, confused. In general, the communication response activity I see in the event viewer log looks rather good. Two or three hops remaining fall all devices (Including older I1 devices). You may have some communication issues, but they were not apparent in the log. That's good. You may have "isolated" issues on some circuits, rather than wide spread issues due to a problem PLM location. Suggestions: Insert some short waits between some of your Insteon commands. If you suspect a scene issue, insert a longer wait before the scene command. Your programs were attached in an XLM format. Very few forum members can interpret it (and I have trouble). If you would please right click on the program and select "copy to clipboard", you'll be able to paste a "text version of your program. Many far more experienced people than I will be able to assist with suggestions. It looks like the Eisy is still using the deprecated Peek/Poke method of restoring your older devices. Did you try switching the Eisy to the "Device Reported" mode under "Advanced Options"?

PLM Problem? Uncommanded ON for multiple devices
@walkman9999, unfortunately I am traveling through Friday. Can't help with the link tables at the moment. I did look at the restore log. You encountered an error writing to a device 1b.b0.cc. This looks like an older device that may be powerline only. As @oberkc indicated, this device would be a prime candidate for a restore. I'll try to have a look at the rest when I return.

PLM Links Table question
As usual, I could not leave this alone... Anyone who has read my posts knows that they are rarely short, and never very interesting. Read on at your own peril... I ran another test deleting a KPL from my PLM. I compared the PLM link tables before and after the delete. Observations: The ISY deleted the control link (E2) for group 0 at address 14H from the table. This makes sense - leaving the link would allow the PLM to try to interrogate the device even though it didn't exist. Think PLM timeouts, retries, and the whole mess. The ISY DID NOT delete the responder links (A2) for groups 1 though 6 (main button and secondaries). I suppose these are viewed as harmless links. The can't do any damage if the device isn't there to communicate with the PLM. With the "deletion" of the Link @14H, all of the following link addresses shifted up by 1. The PLM now shows 1 fewer total links (497 vs 498). The above makes sense to me except for Item 3. There is no way the ISY had time to delete the link @14H and REWRITE ALL OF THE FOLLOWING links. Anyone who has restored a PLM knows it takes a significant period of time. This operation took seconds. This leads me to the conclusion that the ISY DID mark the record @14H as "available" (22). During the subsequent PLM link table read, the record @14H was IGNORED since it was marked as "available". The PLM Link read operation is very different from the device link read operation. The device read operation is handled by the ISY through read commands for each link location. The ISY displays all Link table information including "available" records. The PLM Link Read operation is handled by the Insteon "Get Next ALL-Link Record". This command apparently skips the records marked as "available". I now yield the soap box... IM

PLM Links Table question
@Tmc, my apologies - I was wrong. I just deleted a device from my system and the PLM responder links are still are still there. I'm scratching my head at the moment...

PLM Links Table question
@Tmc, you are correct that there is a record with your device address still in the PLM. If you look at the flag column you should see a "22". This is the sign that the ISY has marked the record as "Unused". In order to completely remove the information, all of the links following the record would need to be removed. Simply marking the record Unused gets the job done quickly. If you find that you have many "unused" records you can perform a PLM restore to rewrite the entire PLM. The ISY will remove the unused records. The same technique applies to devices. The "22" is used to mark records unused, and a Device Restore will rewrite and remove the unused records.

Write to device fails after PLM replacement
@walkman9999, your Switchlinc Dimmer appears to be a 2476D that is powerline only. Communication with the device isn't great and that can be a problem when trying to restore a device. It might be possible to install a dual band LampLinc or other RF device electrically near the Dimmer to help with communications. It's also possible that the noise or signal absorption is temporary due to a problem device in the vicinity. Try inspecting for typical problem devices (PC's, chargers, UPS's, etc) in the vicinity. Another thing that is not in your favor is that the ISY is using and old I1 programming mode with this device. The Event Viewer communication below is from your Restore sequence. The Red section is where the ISY attempted a I1 write sequence that timed out after 3 tries. The following green section is a successful write that was performed using I2 (much faster). You could try to "force" the ISY to use I2 communication by going to Link Management/Advanced Options and selecting "Device Reported". The I2 protocol allows the ISY to transfer data in far fewer command sequences than the I1 mode. The communication is still susceptible to noise/absorption issues, but there are far fewer opportunities for failure.
