Not too sure if this will be what you need. https://developer.isy.io/blog/NVMe/

I have used the loX Finder (start.jnlp) on my ISY994i with the last firmware for it. On a Windows 10 setup. And it works fine. With the Java it has installed.

The 2456S3 has local control sensing and the later Rev 4.0 have a snubber network across the relay. Both will cause flashing or dim glow when off. Putting a small incandescent load or old wall wart. On the string with a outlet tap. May times will correct the issue. The disabling the load sensing does not turn off the sensor voltage. Just the 2456S3 ignores the load changing. So the small current is always there. Even when disabled. The 118 volts is through a high resistance and most meters with a high impedance will see the voltage but the low resistance of the bulb will load it down and the meter will be close to 0 or 0 on the meter. Do they click with no load? Not too often seen but maybe the load is sucking up the power line signals.

I actually saw a condo. Fed from three phase. With each unit using two of the three phase leads and common. To help balance the power line feed. Each unit had 120VAC neutral to each line and 208 line to line. I believe the high voltage appliances where made for 208 or wired for 208. 120 degree phase separation.

Your PLM information. Indicates it is fairly old. Also with only two links. I would suspect the PLM is failing. As two links is way to low.

I don't think that it listens when in power saving mode and not woken up to see commands. It may not even have an RF receiver in it.

Sounds correct. The RJ45 serial 2413S PLM end only had three sires connected. From other posts here.

Be careful. The RJ45 network style serial connection on the PLM end only uses three wires. Other pins on the PLM end are not serial like send and receive TTL level signals. That should not be connected to anything.

Another symptom is a dim or out LED on the side. Can be rebuilt built. These days most go the new latest version PLM.

I believe you also had post on the Insteon forum. I posted a link to the manual there. Though you may already have it since you are using on already.

Yes it is old and 26 pages long but you should find information in it. https://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/

Try clicking on the data line it is displaying and chose of you want a LAN or cloud connection. I use LAN myself. If the LED on the side of the PLM. It is an indication it has failed. If you are handy there are repair threads on repairing them.

I have a few spare PLM modules. As I like to look for obvious changes in the PLM. Along with a spare ISY994i.

Try a power supply. When they fail all kinds of strange things happen. I have had at least one on an ISY26, ISY99i and now a ISY994i. Since you tried more than one PLM. Try a new cable between the PLM and your ISY994i. They have on occasion gotten flaky.

Insteon dual band devices also have a built in communications test you can use. Some manuals call it the 4 tap test, some the beacon test and some have a flow chart to follow to enable the test. The dual band modules and their range extenders [dual band 2477D2 Lamplinc with the dimmer parts left out]. Do not couple or pass on X10 messages. Many of the passive X10 couplers will also couple Insteon power line messages. Some of the active X10 coupler repeaters can see the end of an Insteon power line massage as a bogus X10 message and try and repeat the command. I have a XTB-IIR that knows enough to not false on Insteon. So in my case I have a mixture of X10 and Insteon devices.

Did you have a chance to look at the revision of the 2443 Access Points? Any revision of 2.0 and above are base 2413 PLM electronics and can have the same capacitor issues. One of mine the LED on the side was off and the second one was very dim. In my case the same capacitor fix for the 2413S PLM worked. You can try power cycling them and see what happens. You can also do the 4 tap communications test on them. 4tp test also will run on the 2413S.

You may also want to run the built in tests between the two 2443 access points to see if they are still communicating. If they are any revision 2 units. They are built on the base 2413 PLM and have the same capacitor issues as the 2413S PLM. I had to rebuild mine with capacitor issues.

The DST issues where also reported on the Insteon Forums. So the ISY products where not the only controller with possible issues.

My older ISY994i changed as expected today.

Also they are RF devices and go in to power saving mode. Each one has to be woken up individually and then do a restore on it.

Module has to be restored as there are writes pending to the module. If battery operated module has to woken up first. Also effected by turning on and off automatic writes or battery devices.

If some of your modules are the older power line only models. They can be effected by power line devices as the new devices in the house are added. So in theory older modules may not fair better. Even with the great UDI products.

You may have to have the special UDI USB adapter on the Polisy end. As I am not too sure if it can do serial. I know the eisy can not do serial. There are other signals on the RJ45 style connector that you do not want to connect to anything. Like TTL signals.

The 2413S has a special pin out on network style connector. Only three wires are used. Common, Send and Receive are connected. The signals are true RS232 with a Serial Port interface chip. At the least you would have to create a special cable.

Are you using the USB to Serial adapter cable? The eisy does not work with a 2413S serial PLM. Unless the adapter is used on a USB port on the eisy.
