Can't comment on the color wires. Yes just 3 wires. If yours is working then you got it correct.

Yes both the IRLinc Transmitter or Receiver. Are both power line only. Faded memory here. I believe they where in the drop down list with other unique modules like the motion sensors.

Just try to duplicate how the old one is wound and taped.

I have some power strips that also have a AC rated Capacitor across the line and load. They work good to remove power line noise but also absorb Insteon and X10 power line commands. That extension cord. Looks like it has no signal conditioning at all. Turning off load sensing may show something. Capacity of the two conductors or noise absorbed by the coiled cord. Maybe but maybe hard to pin down.

Openadr was standard in every ISY994i Portal Integration and Networking where purchased added modules. You can no longer purchase them and if you want to transfer it from one to a different one. The end of service post. Seemed to indicate they would do it for $125. I only used the A10/X10 module as an example. I don't know how many here actually have it. Now over on the X10 forums. Where I am a Community Advisor, I have seen some using an ISY99i or ISY994i exclusively for X10.

Especially if the load sensing feature is on.

If the restore from a unit with the A10/X10 to one with out the A10/X10 module. It probably would go through but if the A10/X10 module's features where being used by the old ISY994i. It could cause issues. Though that module was cosmetic and allowed X10 and A10 module to be seen in the console tree. Data on the A10/X10 feature. Just the info. Being available now is over. Since the ISY994i is discontinued a few years ago. https://wiki.universal-devices.com/ISY-994i_Series_INSTEON:Enhanced_A10/X10 We have seen issues with a backup from a PRO on one with no PRO. If the scene and programming information was larger than the standard unit was using. I don't have any thoughts on the. Portal Integration module.

Did a test with my spare ISY994i. Using a backup from my main ISY994i. Spare does not have the Networking Module installed. PRO,A10/X10 are on both. Also no installed Insteon modules in the spare. The backup for the main unit did program the spare. Including the Insteon modules in the main unit. Insteon modules didn't respond to tests as the PLM on the spare has a different six digit ID. The Networking Module did not get installed from the main unit backup. Password from the main unit did transfer to the spare. As did the name of the ISY994i. As my main one was an early one called My Lighting and the spare ISY. I don't think an ISY994i that includes the PRO add on. Would be a problem. As it adds more space for programs and scenes. Control of automatic writes to changes to the system. Going the other way may make a difference if the original with PRO had more programs and scenes in it than one without the PRO.

Yes the Polisy section of the UDI Wiki shows it has serial port. Polisy supports the following PLMs: 2412S and 2413S through the DB9 connector on the back. 2413U and 2448A7 through the USB port on the back. If you have a 2413S (serial), you will need our Serial PLM Kit. My thought are if you want to use the 2413S on a USB port then the adapter is needed. Since that model is supported. Opening a ticket may get more results. https://www.universal-devices.com/contact-us/

The modules are tied to the ISY994i's UUID number. That is different for each ISY994i. If you buy a used one ask the seller exactly what it has in it. You may find a similar set of modules in the replacement. The backup has the scenes, programs and setting in it. I don't believe the backup has the firmware and installed modules. My backup files also have the title with the UUID in it and my second ISY994i has its UUID in the backup's title. I will try a test if I can. To see if a backup from one ISY994i worked on second ISY994i. If both have the same set of modules them.

5.3.4 is the last firmware version for the ISY994i. It is what I have in mine and a spare. Manually is the only way. With the firmware file. To see the whole thread. Including a link to the firmware Click on the up arrow in the post from Geddy

If you can get into the Help Info Tab on your present ISY994i. It will tell you what you now have. So you can see what the ones on the auction sites have. Like the Pro and other add on features are in them. Pro adds more link and scene space you can use in the ISY994i and also allows you to turn on and off automatic updates. Your present ISY994i may also have other ones like Networking. So features you now use will still work if you get a replacement ISY994i.

Long shot here. We have seen strange things happen when the wall wart supply starts to fail. You may want to just try one and see. ISY994i has a wide input voltage range. UDI last time I looked was selling a 12VDC 2A. My originals where 5VDC 500mA or 1A

The cable between the ISY994i and the RJ45 style serial port on the PLM. Is a standard network cable. So trying new one should not be too hard. Mine came with a 3' Cat5E. I am using a 6' Cat 5E from my ISY994i and the PLM. The SID message could mean the SD card in the ISY994i is corrupt or failing. There are some reports of that also.

The choice was by the former owners Smartlabs/Smarthome. Some of the other pins on the RJ45 type connector. Are TTL in and Out. Older 2412S also has a unregulated +12VDC (19VDC)thankfully not in the 2413S PLM.

Correct on the USB to serial cable. The PLM serial USB to RJ45 connector side uses three connections (Send, Received and Common) not in the normally used pin out. The UDI one is special in its connections.

The I/OLinc has a switching power supply in it. Along with the capacitor issues. They did replace the main cap with a larger capacity one with a higher voltage rating. My old V1.0 the supply voltage dropped every time the relay was turned on.

If you have all the features you want or need and a new supply puts you back in business then an upgraded ISY device is not need. Though new features are nice. I don't need and use any of the new features. So my ISY994i will be all I need and use. Besides I even have a backup ISY994i.

Power supply was one of the frequently reported issues with an ISY994i and older ISY99i. My original was a 5V 500mA and it failed similar to what you where seeing. After an AC outage and restore. The LED's sarted to flash as it tried to boot and then reset due to low voltage.

ISY994i has a wide DC input range. Many here use 12V 1 or 2 amp. Been awhile but last time I looked. UDI was selling 12V 2A units for the ISY994i https://forum.universal-devices.com/topic/31558-isy-994-power-supply-question-regarding-voltage/

Plug in On and Off module? Not one of the new dual function I3 switches that can be a dimmer or a switch? The dual function module look like it has a triac so it can dim maybe in on off it is locked on or off. Unless they have a triac and a relay (doubt it).

If you did not use the replace with function. All the modules being controlled may still have the old KPL ID in them and will not respond to the replacement. With out some manual intervention.

I would also suspect the PLM. If it is a 2412S. It would also be supplying unregulated filtered +12VDC to the EZIO8SA. On the serial cable from the PLM to the EZIO8SA. It is usually around +18VDC. I see you also have a power supply. If the supply is 12VDC the 2412S is running it. As there is a network in the unit to use the higher DCV. Now if it is a 2413S the external supply is needed and 2413S PLM units have a poor reputation especially the early versions. If you post the PLM data someone can give you more information. As it could be one of theirs also.

Well one thing to think about. There was a word wide wide IT outage early this morning. I know for a time. There was or still is a FAA ground stop for all major airlines, some Microsoft Windows functions where not functioning, some banks where having issues and some Amazon functions also where not working. Overseas where also having assorted issues. Cloudstrike was mentioned. On the front page of the Frontier web page. Could be completely different than this but could be a possibility.

Not too sure if they are close enough in features. If the replace with choice is there. That would be the easiest. It does sound like the old one is failing. Probably a power supply issue.
