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.

You may want to look at the +5 volts to GND on the I/O terminal block to see how it is acting. Since C7 is probably horizontal to the PCB. If you are careful there should be ~22VDC on C7. That may give some clues. Since the PCB is double sided with plated through holes. It is possible one got damaged and is no longer making connection between the layers. I know I damaged one in a 2443 V2 Access Point and I had to use some wire wrap wire to reconnect the missing connection. Small solder splash bridging runs. It is possible the small transformer in the switching supply went bad but it would not be on the top of my list. Maybe a diode or Zener could have also been bad.

You can still find it in a web search. I suspect it was discontinued. Though the page I found in the search. Says "GET NOTIFIED WHEN BACK IN STOCK". I also think the older designs and slow movers maybe gone or on their way out. The new owners have said they are Internet Things oriented. https://www.smarthome.com/synchrolinc-insteon-2423a5-power-synching-controller.html I just ordered a new 2413S PLM in the sale. Will be reporting on it in a week or so. If I read the sales page correctly. It indicated a larger link database. >2000 over the 1000 in my V2.3. Time will tell. I did see a photo and the serial daughter board is a new one.

Wanted to verify. Are the Cree's dimmable? Most of their products are. Can you tell if the noise or buzz is coming from the electronics and not its buzzer? Some dimmers will buzz when near 100% On. Maybe you have one with a slightly loosely wound coil in it.

Do you happen to have a X10 Coupler/Repeater still in use from your X10 days? Some of them where known to cause firestorms in some conditions. If disconnecting the X10 wall switches doesn't stop it. You may also want to turn off the coupler/repeater circuit breakers. Then see if it is sending the firestorm. If you have a smart meter from the power company. Though rare. There was one system reported on the X10 forums that was causing issues.

The power line is flooded with X10J Status Requests. Interfering with the Insteon controller sending anything. What is controlling the two remaining X10 Switches. If you are using a controller. Unplug it and see if the signal firestorm stops. Two way. They have an X10 transmitter in them to control other X10 modules or they are in a three way setup where either one can turn the light on or off? If they don't have a X10 power line transmitter in them. They can't send any X10 signals on the power lines. You may have an electronic device making power line noise. Being seen as a X10 J Status request. Any new electronics in the home? You may want to go around and unplug things and see if anything changes. You may find some information on Jeff's excellent set of X10 troubleshooting tutorials. The one on the cell phone charger and CFL-LED bulbs are very interesting. http://jvde.us/x10_troubleshooting.htm

The typical failure was their choice of filter capacitors in the switching power supply. Real long thread here on repairs we did ourselves. This also applied to the 2443 Access Points hardware 2.0 and above. Along with some of the Smartenit modules. They also where on the same base main board. https://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/

I don't think anyone has the latest revision that is more than the two year and a few months typical failure use time. So the jury maybe out on is the reliability issue fixed. The UDI PLM was never completed. The promised firmware chips or license to program Insteon firmware into it. Was promised and then later management canceled it. I believe it had to be mothballed. I would think you could use any Dual Band device in the second outlet. So the extra PLM isn't powered up all the time. The passive coupler could be used but I would test how the system is working with no added devices in the second outlet.

A great loss to all users Stu has help. https://forum.universal-devices.com/topic/24103-sad-news/

I still use a HR12A and UR19A remotes. Through an RR501. To control my older Insteon modules that could be programmed with an X10 Primary Address. X10 chime modules triggered by an ELK930 Doorbell Sensor. The chime modules also get sounded when it is time for my ISY994i to wake me up. I do have a JV Digital Engineering XTB-IIR coupler repeater. Blasts over a 10 volt X10 signal on the homes power.

UDS? You mean UDI? The Simplehomenet products do some unique things with the Insteon protocol. That only they seemed to use. For awhile Simplehomenet {now Smartenit} was not providing information to UDI so total support of their products was not possible. Not too sure if they freely exchange data now. I think the other program you maybe thinking of. Was the Simplehomenet Utilities. I looked and the link seems to be gone . Their help forums also seem to be gone of new posts. Just what was there a few years ago. I did find it directly where they stored it. https://sourceforge.net/projects/shnutilitysuite/ My EZX10RF was an early model and it would take an All Units Off and resend on the power lines a All Lights Off. That my X10 appliance type modules ignored. Sent it back and they reflashed the firmware. Unfortunately it still did it when I got it back. Sounds like something may have changed. X10 RF remotes always send multiple RF commands. Your unit for some reason is decoding it more than one time for each button push.
