I would suspect the wall wart power supply getting weak and causing the unit to do a reset for the password issue. They are known to go bad and start causing problems.

Good to read you found the problem. My bet would be on the wall wart supply.

The PSC05/TW523 is long gone for years now. The XTB-523 is still showing. Since it used a unique set of commands and is opto iolator input signals. Probably not a good way to go. I also think the 2413U USB interface still does X10 commands. As long as the eisy can send and receive X10 commands. If you had the A10/X10 add on module. To have the X10 modules displayed in the module tree. I have not seen anything on it for the eisy. X10 support was one of the original selling points and I doubt it would have been removed.

It should not be using I1 as that module is I2CS and is dual band as you found.. I believe some commands are I1 to determine some information before using I2 or I2CS.

The log shows the I1 protocol is being used. That requires a lot of messages between the controller and the module. Also power line only as pointed out. Another thought is something has changed on that circuit. Like a new signal sucker or noise maker. Besides the fact is is old and maybe on its last legs. The 2477D is dual band so both Insteon RF and power line commands are being used and It is an I2CS device. One command for each byte of data and it has a check sum to help verify the message is not damaged.

The one UDI sells last time I looked was 12V 2A. It has a wide voltage range. My failed one was 5V 500mA but it is recommended you go with 1 or 2 amps. 5V and 12V seem to be the choice of many.

The I/OLinc is a power line only module. If you have a new noise maker on the power lines or a device sucking up the power line signal. You can get no communication to it. If you have a spare dual band module. You could test communications with it in the pass through outlet on the front of the I/OLinc. Another thought is a filter capacitor. That module also has a switching power supply and has the same problem like the PLMs have had.

Glad you found your solution. Misread ID is one of the more common issues. Some are hard to determine between some characters.

Check the power supply or better try a replacement. Known problem for many ISY994i users. That a new supply fixed. Has a wide voltage input range so you may have one handy. No Blue or dim Blue Power On LED would be a clue. Mine just tried to reboot and then tried again in cycle as the supply didn't have enough in it to keep it running. Blue LED kept pulsing on and off.

Here is some information on the ISY994i and its SD card. https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:Replacing/Formatting_an_SD_Card

Just cap it Off. Not capped of could be a problem if it accidentally shorted to something else. Is a common practice even some manuals show that fact to just use the module to control other modules. It is a power line only Insteon Module. If the renovations changed the wiring. You now have a new power line noise maker or signal sucker. That maybe what you are now seeing. As a test or maybe a fix. Depending on having a plug in Dual Band module. Try plugging in a Dual Band module on the KPL's circuit and see if it then can be accessed.

Make sure the PLM is powered on first and fully booted. So the eisy can find it when it boots up. If it has failed and less than 2 years old. You might have a warranty claim. What is the information on the white sticker show? It will give a clue to some things related to it.

Log shows it was not replying to your messages. Only the PLM acknowledging the message from the ISY. Moving the ISY did then find it. There maybe a distance or signal blocked by something. Since it is an RF only device. Moving it let it communicate. You did wake the sensor up before trying to add it?

If this was some older 2456S Appliance Linc units. There was actually a firmware version. Where someone at the old Smarthome. Thought it was safer to always start Off even if it was On at power loss.

For the two that will not register at all. Double check the six digit Insteon ID Number on the sticker. It is easy to misread the some ID characters. Like 0 and a D for one. A wrong ID would certainly cause that error. Anything new or moved electronically. One possibility is a noise maker causing communications errors. Since I am staying with my ISY994i and do not have your system. I can't say if the problem is a software issue.

Extending distance may depend on the serial interface chip in the adapter and maybe the 2413S. V2.3 added a more ESD safe serial chip. V2.4 added the chip and a transient suppressing network on the two serial signals to the outside world. On an updated serial port daughter board in the 2413S I have see ISY994i users having success with extending the serial cable to a longer distance. Between the 2413S and the computer. Maybe the same for an EISY adapter. If you want to see what a serial connection is OK to run on. 2413S PLM. 19,200 Baud, 8 Bits, No Parity, 1 Stop Bit. No hardware hand shaking. A standard network cable is four twisted pairs of wire. Pair 1 is 1&2, pair 2 is 3&6, pair 3 is 4&5 and pair 4 is 7&8.

The RJ45 Serial Connector. Is a serial signal on a Network style cable and not a network signal normally on that type of jack and cable. So there is also a limit on the length also. If you do try and make a cable. Only three signals are used and their position is documented in the PLM Quick Guide. Since other connections are things like TTL level signals. Best to not carry them through the cable at all. I suspect UDI has their adapter made to the three signals only needed on the serial side of the adapter. RJ45 pin 1 RS232 to PC Pin 2 (RX), RJ45 pin 7 Common/Ground, RJ45 pin 8 RS232 from PC Pin 3 (TX), RJ45 pin 3 TTL Out, RJ45 Pin 6 TTL In.

Rare instances. Power line noise may fool the PLM into thinking there is a valid message in progress. It will then wait on both power line and RF messages until it thinks the massage in through. I agree your Link Database is too small for almost any system.

Have you tried the default admin admin. In case it changed back to default during the update. Do you have a series 300 or 500 Z-Wave board. As there was only 500 series in the later revisions.

Verify the PLM is powered on and completely booted. Before you start the eisy. So it is found when it is started up.

There may still be a firmware update but limited to the last one supporting a 300.

The 2466S is a power line only relay style module. Sounds like it has failed as you expected. Since you chose the 2477D dimmer. Replace will not work as replacing a relay with a dimmer will not give you a choice.

Z-Wave may depend on the board installed in it. 300 or 500 series. https://wiki.universal-devices.com/index.php?title=Resetting_Your_ISY I am like you. My ISY994i is still 100%. If I can get answers from users here. It will be fine for me. I updated mine and its backup to the latest firmware and added a few options to the backup. Before they where discontinued. Now if you wanted to use some of the latest I3 Insteon Products or third party programs. Then an EISY would be needed.

I have seen other Zwave modules with a similar must be with in 10 feet for Include to work.

Also when on a dimmer. Verify the LED bulb is rated to be on a dimmer. Not all of them are made for a dimmer. Also may have mounting restrictions. Like not in a totally enclosed fixture or damp locations.
