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.

Hardware issue. The LED is driven right from the ISY994i's internal power supply. So the LED itself or the current limiting resistor are the most likely candidates. If everything else seems to be OK. It may just be a LED failure.

Try a different power supply. There have been reports here of this problem. There are a few message threads here on the same problem you are having. If your old supply has a LED on it. It may not be On or is very dim. I have had three power supplies fail. On various models I have used over the years. ISY994i has a wide voltage range it can use. 5 to 30 Volts DC Center connection is +. Mine where all 5 volt ones. Many here have used 12 volt ones and UDI sells a replacement in their store. 12 volts 1 amp.

Possible the DC output from the old supply. Was full of AC ripple and the ISY994i could not use it but the LEDs sill where lighting. Maybe dimmer than normal.

Thank you for the update. Good to see it is functioning OK. This is from an I/OLinc Hardware Revision V2.3, firmware 41. If yours is newer it could be different. On mine pushing the Set button to toggle the relay. Does not send a signal back to the ISY994i. So it will have no idea you used the local Set Button. To trigger any program.

I have some of the original revision. 2476S SwitchLinc V2 modules. No Air Gap switch. Factory reset was a combination of holding the top paddle for ten seconds and release. Tap the set button. Then hold the set button in for ten seconds.

The 2457D2 would work fine. The 2992-222 Range Extender is a 2457D2 with the dimmer components not installed.

If set to Momentary A as shown for 2 seconds. It should just pulse the relay for 2 seconds and then it would go off. I suspect it does not send a signal back to the ISY994i and it thinks it may still be On. You can look at the LED on the side. If it is dim the relay is Off or Bright it is On.

You asking about the Magnetic Switch or the Output relay in the I/OLinc. The internal relay should be set to pulse on for a few seconds. To simulate you pushing the openers control button. The magnetic switch is designed to be On when the magnet is close to it. As it is a security systems sensor.

The magnetic sensor in the kit was changed awhile back. Did the old kit have a magnetic sensor. That had three connections? Normally Open,Normally Closed and a Common. With the old model sensor you could wire it On. With the magnet near the switch or away from the switch. It could also be possible. They changed the magnetic sensor. So it is now in the opposite state when the magnet is close to it.

The FCC internal photos of a 2475D2. Show it has a switching power supply. Not too clear what type electrolytic capacitors are in it. So not immediately clear if they are rated for a switching supply. Like the 2413S PLM issue we have seen. I may pop one open and give it a look. One symptom on the 2413S was worked for awhile then stopped. Powering it down and let it cool off. It would again work for awhile.

Is it the older power line only 2456D or the newer 2457D dual band model? If it is the older model 2456D2 or 2456D3. I would think it maybe starting to fail. I had the On/Off model 2456S3 starting to pulse on and off at about a 1 second cycle. Was a bad capacitor in the unit. I don't have much experience with the 2457D modules. It could be starting to get flaky.

Wrong UI version. The ISY Launcher. Picks the correct UI for the firmware installed. https://forum.universal-devices.com/topic/24381-isy-launcher/?tab=comments#comment-242590
