Since the I/OLinc is also power line only. You may have some new or declining electrical device in play.

Yes. You can use them for better communications. I have two of the older style 2443 Access Points. In the ISY994i system. You don't add them or the Access Points to the Administrative Console. Just plug them in. You can use their built in communications test if you want to see how well they are communicating. If you care too. I can't comment on how a HUB handles them as I never use a HUB.

The 2450 I/OLinc also has a switching supply. My old ones was a 10uF/25V C7. Then they tried a 10uF/50V C7. My latest one is a 220uF/50V C7.

You did a Factory Reset on the SynchroLinc? That should have cleared its link database. I tested with a Factory Reset SynchroLinc and added it to my ISY994i 5.0.16C firmware. The show devices links test showed one entry. The link starting with E2 and then the PLM's six digit Insteon ID. I looked inside mine and as pointed out by larryllix it has the poor capacitors in it as a PLM and the values seem to point out it also has a switching power supply. Though the supply chip must be on the solder side as I can't verify it is a switcher.

If the problem moved to where ever you installed it. It does sound like it was a bulb possibly making noise and triggering the 2457D back on.

What Insteon module is controlling the lamp? Some Insteon plug in modules have Local Control Sensing. If the module was off. Toggling the loads local power switch off and back on would turn the module on with out an Insteon on command. The electronics in some LED bulbs could trigger them back on when turned off.

I too have had a few wall warts fail. On ISY99i and newer ISY994i. I would try a supply and see if things are better. If the ISY994i works correctly but the power LED on it is off. There are a few reports here where the power LED does not light but everything else works 100%.

The hardware revision number is on a white sticker on the back of the PLM. You have to start a communications test from another dual band module. For the LED to flash red or green. Some modules out of RF range may not cause the LED to flash at all. Goes On and then Off is something I am not familiar with. So I looked at the Modem Developers. There is a data bit that can be set in the Set IM Configuration command to turn off Automatic LED operation. Then an LED On or Off command is then needed to turn the LED On and Off. I can't imagine how that could have been set or even if it is the problem.

Mine is also on solid green. If a dual band module is doing a Communications/Beacon/4Tap test. It may flash green or red. To indicate it is receiving the test signal and on the same or opposite phase of the power lines. What hardware revision is the PLM and its firmware reported in the PLM Info/Status test in the Administrative Console tools?

The manual and photos of the 2234-223 Serial and 2234-222 USB versions. In the FCC Database. Indicate it has a universal power supply 100VAC to 240 VAC, 50Hz/60Hz. Larger Link Database of 4000 over the 2413S 1000. Internal photos show a separate AC input plate. Only a guess but it should be easy to change the plate to match other parts of the worlds AC standards and tune the RF section to match other countries allowed frequency. So maybe eventually others may see a PLM that works in other areas of the world.

If you factory reset the modules and are using a HUB with an ISY994i. The reset will clear out all of the links in the module including the HUBs Insteon ID and links it wrote to the module. So the HUB will not control them. The ISY994i and HUB will not know each other or see changes made. So they could over write unknown links from the other interface in the modules.

Where the Switchlinc modules linked with the manual set button method or did you use the ISY994i to do the linking? The ISY994i should be used to do all the linking between modules. Manual set button links maybe corrupted or over written. Many here recommend a factory reset on any system that was manually linked. To start fresh with no possible half links in modules.

Salt may eventually corrode the sensing pads or maybe do a false wet condition. If the salt absorbs some moisture from the air.

I think the Power LED is run directly from the ISY994i's internal power supply. As the power LED lights almost immediately on powering up the unit. If the ISY994i is working normally except the power LED is out. The LED or the current limiting resistor for the LED has probably failed or their is a bad solder joint, PCB run. If the whole thing stops work after trying the recommended 30 second power cycle. The wall wart is probably failing. I have seen another post here where the power LED was out but the system was still functioning. I would see what UDI says about it.

Both the Insteon modules you posted on. Are not in any version 4 firmware. Took quite awhile for my siren modules sitting in storage for version 5 to be released. As Smarthome dragged their feet on getting UDI needed information on both modules and the Alpha and Beta releases of 5 where tested. I am using 5.0.16C as I have no need for any present ZWave card support.

If you want to go safely. Smarthome has the 2472DK replacement key showing as in stock. $1.99 but I suspect shipping will make it a much more costly purchase.

It is a magnet in the key that you put on to the device plugged to it. You can tape a magnet over the area where the key normally activates the outlet to operate.

Some electronic devices. Have a nice AC rated capacitor across the power line to keep its internal noise off of the power lines. That capacitor will also absorb Insteon power line signals. All it would take is the manufacturer to put a coil on the input before the capacitor to fix the issue but that would add a few pennies to the parts cost of the unit.

The new LED disk light is rated to be on a dimmer and the manufacture did not say it had to be on a dimmer specially designed for it?

New devices may cause issues. There is a tutorial on such things in the JV Digital Engineering troubleshooting area. A cell phone charger made lots of power line noise directly on the X10 frequency of 120KHz. That is not very far away from the Insteon 131.65KHz. Older Insteon modules like the 2450 I/OLinc are also X10 enabled.

The six digit ID number sticker was inside the battery compartment on all of mine. Not too easy but in a pinch you could manually link it to a module in the ISY setup. Then do a Show Devices Link table on that module. Then a compare. The extra link in the module is the six digit ID on the 2440. I found with mine it could not be close to the 2413S PLM for it to use its Insteon RF receiver. I had to put it far enough away to make a different RF receiver like an Access Point, Range Extender or Dual Band module to receive the RF commands and relay them back to the PLM on the power lines. I had to start the 2440 in its linking mode than run back to the ISY994i and start the adding the module. Are you using the Link a Remotelinc choice in the Link Management Menu? Where you put the six digit ID and a name for the 2440 into the add screen. Then put the 2440 into its linking mode and tell the program to find it. The Start Linking mode has never worked for me only the choice in the Link Management menu. If you have a PRO version. Enable automatic writes to battery modules. The old RF receiver should not be needed. Though you could temporarily put it back far enough away from the PLM so the power line was used back to the PLM. Then use it to add the 2440 into the system.

What version firmware and does the UI match the firmware version? What is the device's part number you are trying to add? Looks like you using the Start Linking method and not the Add a New Device choice from the drop down menu? From the Event Viewer information you posted. After the initial ID by holding the Set Button On the Device and it being seen. It is not sending back any more details on what it is. When it is being sent a request for information on it. You may want to try a Factory Reset on the device and see if it may have some corrupted information in it.

If you just disconnected the old PLM and did not reboot the ISY994i. It will think the old one is still there. As the PLM is detected when the ISY994i is powered up.

The replacement supply in the UDI store is 12Volt 1 Amp. So that will be fine.

Homelink uses X10 310MHz RF frequency. So the 2342-222 Mini Remote can not directly control Insteon modules. As Insteon is 915MHz. May be the remote could trigger an Insteon program or scene. The ISY994i and PLM can do X10 power line not RF. Can't say about the Homelink Poly.
