Yes I saw that. It was on the sales page when I ordered one during the 25% sale. Guess the sales page was updated before the older stock got sold. Mine did not have the features listed on the sales page. ?

Any Insteon activity while the Link Count is bring done. Can effect the results. I have seen the Smarthome sales page. Saying the PLM now again has a >2000 Link Memory size. Though I have never seen a 2413S with that size. The later production 2412S did and the ISY {I believe it was a ISY99i} controller had issues if you got maybe over about 800. In that case it was the slower memory speed in the 2412S.

The XPF is a 20 amp filter. It is BIG and fits in a triple electrical box. If you wire it in to the breaker panel on a branch circuit. Everything on that circuit would be filtered. Though you maybe able to just filter the feed just to the lights themselves. You would only need one. If you can filter all the lights feed. The link in the earlier post . For the XPF has a manual you can download and see how it connects. I believe some here have used the XPNR wired across the noisy load. Maybe someone could post their findings. https://www.x10.com/x10-pro/specialty-devices/filters/xpnr-noise-reducer.html

This is from the UDI Wiki. https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:File_Menu#Restore_Modem_.28PLM.29 Are any of the LEDs on the front panel On or flashing? Except the power one that should be On. Did you use the tools PLM/Info status test or the Show PLM Link Table test? What did they indicate? An empty or very small table can indicate a PLM issue. One thing if you power down the ISY994i and PLM. Power up the PLM first. So the ISY994i can find it at start up. There is a real long thread here on the 2413S PLM failures and how some of us repaired theirs. It may give more clues. https://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/

You do not need a PLM if you only have Z-Wave. If you have a mix of both Insteon and Z-Wave or only Insteon then a PLM is needed. If you have Z-Wave only. There is a version of the firmware that does not go into safe mode if no PLM is found. There should be a link on each firmware versions release pages on the forums here. You can also use the one with no PLM check and still have a PLM. Just if it dies you will not know it.

Sad to read of your PLM failure. I have seen some changes over the years but seems their guesses have not worked well. I know my recently purchased PLM V2.4, maybe higher revision now. Has a redesigned serial port daughter board. Serial interface chip now one with an ESDI rating and two three pin diodes {maybe a spike suppressor} with resistors on the serial signal pins. Lets hope they may have finally gotten their act together. Past performance don't give my much confidence going forward on a decent fix.

That model is the one with the added ZigBee protocol. Not sure about the main board. Users sheet mentions a switch mode power supply but no Insteon RF mentioned. Maybe a custom manufactured base board for them.

There is a very long thread here on the PLM failures and if you are handy. How to repair it. https://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/

Thank you for the cookbook. I will be starting to look at it soon.

You may want to post in the Insteon or Smarthome Forums for better results. https://forum.smarthome.com/default.asp https://forum.insteon.com/

When you installed the new PLM. Did you power off both the USY994i and PLM. Then power up the PLM first so it initialized first? So the ISY994i could find it when powered up? Z-Wave does not need a PLM so it was still working.

As pointed out. There is a special area in the Link Management Tab for Sensors and which one you are adding. As for external Insteon labels. I have a 2342-232 4-Scene Mini Remote. It has a plasitc type label on its back. As there is no way to put it inside. It is now worn to the point. It is impossible to read. Good thing I keep a list of modules their six digit Insteon IDs. The original Remotelinc had the label inside the battery compartment on the lower edge. You are not alone in missing a internal label in modules. Missed it a few times myself.

Teken. Will #14 wire fit into those small terminals on an I/OLinc?

You could also use the builtin communications tests in the LampLincs and observe the findings. Can't say about the presently sold Range Extenders. Mine have the same FCC ID as the 2457D2 Lamplincs and just have the dimmer components removed.

I have found some of the present manuals show the flow chart Set Button, LED sequence. Don't work on the older hardware modules of the same model number.

For some of the other Dual Band modules you have. Consult their full manuals. Some you can tap the set button four times {you may see it called the four tap test} and it starts the test. Some of the later ones have a flow chart in the manual. Where you observe the LED color and blink pattern to choose things.

Have you tried the Range Extenders builtin communications tests? To see if it is communicating with any other Dual Band device or Range Extender?

The I/OLinc is an older design. Power line only module. You may have a communications issue between the ISY994i and the I/OLinc. Do you have any other Dual Band modules in the garage? As a test you may want to temporarily move the I/OLinc to an outlet closer to the ISY994i. If it links there you probably have a power line signal issue. If the I/OLinc is powered by the same outlet as the garage door opener. You could also try linking it with the opener unplugged. That may show if the opener is making power line noise or absorbing the Insteon power line signals.

Try a power cycle reset. Unplug it for fifteen seconds and power it back up. See if anything has changed. If the LED near the set button comes on for a short while and the goes out again. It probably has a power supply issue. As it uses the same switching power supply IC as the 2413 PLM and may have the same capacitor issues. The Green LED near the terminal strip is the sensor On or Off indicator. It maybe out if the sensor is off. The LED next to the set button should be on dim if the relay is Off or bright if the relay is On. It should not be completely out.

You may want to try . Tools Diagnostics Show Device Links Table. Picking the I/OLinc in question. After the links are displayed. There is a choice to compare what is found to what the links in the ISY table knows should be there. If it does not respond. You may want to open the Event Viewer. Set to level 3. Pick the module out in the Administrative Console and do a query of the module. The event viewer will have what messages sent and received back from the module. That may give a clue also.

The latest version is 5.0.12. Listed as Alpha status. Though many here are using it. https://forum.universal-devices.com/forum/108-50/ 4.6.2 is the latest released version and as you have found. The Siren Module is not supported. Along with the short lived Alert Module.

I have a old V1.0 I/OLinc with the under sized caps in it and I busted the buzzer. I maybe taking it out of the case and seeing if anything pops out. Maybe the Zero Crossing circuit.

I don't have any thoughts on what maybe wrong. If something pops into my thoughts I will post.

Sounds like the power supplies are working. Maybe a different component had failed or there is a bad run on the board.

The older revision 1, 2443 Access Points where built on the power transformer based interface. Also used on the 2412 PLM and 2414 PLC modules to name a few. The revision 2, 2443 Access Points are made with the same switching supply, base interface board in the 2413 PLM. As you found they also suffered from the same capacitor problems. I rebuilt a few myself.
