Your thought on the power fluctuations may make more sense. On the off chance the supplies are starting to get weak the power fluctuations effected it more than normally.

Good to see they are working again. One other possibility is its power supply is starting to get flaky. They have the same switching power supply chip in them as the famous 2413S PLM supply issues. I have seen a few different capacitors in them as Smarthome tried to beef up the supplies. The revision number on the back sticker may give you a rough idea.

The fan probably has a line rated capacitor across the AC power input. To keep the fans internal electronic noise off of the power lines and it is doing its job nicely. It would also absorb Insteon power line commands. Making them more difficult to get to where they have to go. Or it is making so much power line noise it is effecting the Insteon power line commands. I wire in X10 or Insteon filter may help. If you didn't find that the bulbs if LED where effecting the commands. I will look to see what is still being sold as many have been discontinued or are meant for a whole branch circuit like the X10 XPF.

Soldering gun? That would be an easy way to burn off a run or two. Soldering iron designed for PC Board use. With a small tip is better. Sudden power loss may also cause issues. When the X10 forums where using a Raspberry Pi. For their custom X10 controller. A disorderly shut down of the Raspberry Pi frequently resulted in a corrupt memory card.

The main board is double sided (may have a layer in the middle not too sure). The board has plated through component holes. Between the top and bottom runs. If you took a plated hole out stuck to a capacitor lead. You then have no connection between the two sides. You may want to give the original parts a look at and see if any of them have a plated through via stuck to it. That may give you some added information on the serial or main board problems. Been there and did it myself.

If it is a standard DB9S connection on the USB to Serial port. It use 2, 3 and 5 on the DB9S side.. The ISY994i uses RJ45 pins 1, 7 and 8. With the signals reversed on 1 and 8 from the 2413S PLM side. So the proper signal is directed to the correct signal pins on the other device. As pointed out by mwester. It is not a simple set of connections and adapters. You do need some intelligence to process the USB signals. The FTDI chip in the 2413U normally needed a driver in the computer to get it a serial port assignment.

The serial cable between the RS232 adapter and the ISY994i does not look like the correct pins are being used. I will have to see what I can determine. I know the 2413S uses Pin 1,7 and 8. To the ISY994i. So it should also use 1,7 and 8 for its connection to the PLMs serial signals. RJ45-1 is the serial out to the ISY994i. RJ45-8 is the serial in from the ISY994i. RJ45-7 is the signal common for both devices. The included cable if used used the standard DB9P pins 2, 3 and 5 to RJ45. The information in the 2413S quick guide. May give you some added information. I will ring out the serial cable included with the 2413S. Remembering the cable was to interface with the PC serial input port. http://cache.insteon.com/documentation/2413Sqs-en.pdf

Depending on which pins where connected. There is unregulated +12 volts (about 18.5 volts) on pin 1. It maybe possible it got into some other signal pin. That would depend on which way it was shifted. I have done a similar thing myself. Though in my error. One or more of the male pins on the main board got bent and ended up on the outside of the shell on the serial card.

I also agree. The pin out digaram on the Amazon site. Shows all the signals on the incorrect pins the 2413S and ISY994i used. You will have to get the correct signals from your converter. To the proper signal connections on the ISY994i. To simulate it talking to a 2413S PLM. Only TxD RS232, Out, RxD RS232 In and SG signal ground are used. RTS,CTS,DSR, DTR, and RI are not used and best not to be connected to the ISY994i Converting the 'B' style to the 'A' style adapter. May also be a problem. The USB connector on the 2413U PLM. Does not have the +5 volt out connection on it. On a 'B' type connection it is a +5V input supplied from the device it is connected too. So you will have no power to the USB to Serial adapter.

Both rows connected but one pin off right or left? Whole row connected to the other row and the other row not connected to anything?

The 2413U USB PLM. Has a FTDI USB interface chip in it. It uses a FTDI VCP driver to make it look like a serial port to the computer. There is no +5V on the 2413U USB connector. It is a B type meant to be tied to an A type on the computer. That has a +5VDC on its pins. The USB (monitor) jack on the ISY994i is described as "The Monitor port (ISY-994i Series ONLY) is a micro USB port used for initial configuration for users without a DCHP-enabled network, or for advanced troubleshooting. Please use a standard micro USB cable to connect your ISY to an available USB port on your PC." The unit wants to see a PLM on the A Serial port RJ45 type connector.

Maybe the serial card was effected. At V2.3 they updated the serial interface chip. To one with a higher ESD protection spec. At V2.4 the serial board was redesigned with the new chip and a protective network was added to the serial I/O lines. I had seen a post that indicated some 2413S units serial ports had issues. Besides the power supply problem many of us have seen. Maybe it was effected by the power issue. You did verify the 8 pin connector between the two board are all in place?

Only the older 2412S provides power over ( unregulated 12V normally about 20V) its serial port RJ45 type connector. In the 2413S they did not put F1 on the serial daughter board. So no voltage was on the serial connector. Starting with V2.4 the serial board is a new design and there is no power to the serial connector. A ISY994i could be powered by a 2412S. It did have the pins wired. It also had a diode in the voltage input. As did the power connector on it. If booth where connected only one provided power.

Thanks for the information. I have the Pi Zero not the Pi Zero W. Though it maybe the same for the USB ports on mine.

My Pi Zero. Has a separate USB connector a power supply plugs into. That has a matching plug on it. The other USB connector is for communication with it.

Let us know if it works with an ISY994i controller. I know the ISY994i checks for a connected PLM at startup. I don't think it uses the subcategory ID. So the serial connected 2413U reporting USB. Should not effect things.

It has been suggested. I don't know if anyone has tried it and reported back with results. I did a quick test with a 2412U USB PLM and daughter board from a 2413S. The 2413 serial board has a faster link memory speed. So putting it in a 2412 should not effect it. It did work in my brief tests with some PLM test software. I did not try it in any further tests. The USB PLM with a serial port daughter board. Will report it is a USB model not a serial model. As they have a different subcategory ID when they are interrogated by software or connected controller. May or may not effect its use. Depends on what is connected to it and if it check for serial or USB.

2842-222 is the original Motion Sensor. Category 10, Subcategory 01 2844-222 is the Motion Sensor II. Category 10, Subcategory 16. You did link them with the Sensors List in the Link Menu and pick Motion Sensor II? If you added them in another way or picked Motion Sensor and not Motion Sensor II in the list. That may give some clues. If it was added as an original Motion Sensor. The features you wanted are probably not available.

The capacitors especially C7 and C13. Have been changed by Smarthome many times. In an attempt to try and fix the power supply issues. They finally went to a 100uF/50V and rated for a switching power supply at V2.3, some earlier revisions had 100uF 35V or 50V. Your C7 and C13 100uF/35V caps where in some of the revisions. One of my original V1.0 has a 10uF/25V and rework to add the coil and both capacitors hanging off the PC Board with a fly wire to back of the PCB. Another common C7 and C13 where 10uF/35V. The C7 and C13 100uF/50V where too big to fit the board space and hole pattern. In those right from the factory. Are laying bent flat on the board with their leads bent to fit into the original board solder pads. There maybe a photo buried in the thread showing them. You will probably have to lay them on the board and connect them to the solder pads. Being careful the leads don't short to things.

If you don't have a PRO. Adding that feature would increase the number of links. I believe it also increases the nodes. If you have the PRO already. Then you have hit the limit. You could ask UDI in a support question. If they don't find it here. https://www.universal-devices.com/contact-us/

I did a few double checks and I don't think there are any errors. C7 and C13. 100uF/50V or 10uF/50V. Earlier ones where 10uF. Smarthome changed to 100uF. May have to lay 100uF on it size. Most are using 100uF/50V for the 10uF/50V. https://www.mouser.com/ProductDetail/EPCOS-TDK/B41858C6107M000?qs=ziqVJVjjmkzaaRB22pWdiA%3D%3D. https://www.mouser.com/ProductDetail/Panasonic/EEU-FR1H100?qs=tfZGHB2PWd1NAbdNSgjToQ%3D%3D C3 10uF/400V https://www.mouser.com/ProductDetail/647-UPW2G100MHD1TO?r=647-UPW2G100MHD1TO C8 10uF/16V https://www.mouser.com/ProductDetail/Nichicon/USV1C100MFD?qs=6UFrbFY2dcTclg9NCH6OBw%3D%3D C11 100uF/25V https://www.mouser.com/ProductDetail/Nichicon/UTT1E101MPD?qs=isV%2BNJxyrb747oJy1YayIg%3D%3D

Well many of the stock numbers on Mouser have a Zero in stock tag. With some expected next year and others are no date known. This blog on a 2413U repair. Same main board in both. Seems to be a good read. https://1projectaweek.com/blog/2017/6/2/repairing-a-failed-insteon-powerlinc-power-line-modem-plm-2413u All of the capacitors it called out are still in Mouser stock (yesterday) except the 100uF/50V. One is a general purpose but in a circuit that should be OK with it. I may try the part numbers I used to see if they have any stock and find a 100uF/50V as I used the older 10uF/50V for C7 and C13.

https://www.universal-devices.com/docs/production/ISY User Guide 4.2.8.pdf https://wiki.universal-devices.com/index.php?title=Main_Page The connection from the ISY994i serial connector to a 2413S PLM is a CAT5e network style cable. Your ISY994i kit should have had the main unit, a power supply, 2 CAT5e Network cables and a Quick Users Guide. Not a normally seen DB9 serial cable. The pin out diagram and signals are shown in the 2413S PLM quick users guide. Only the RS232 Out, RS232 In and Common Ground are used. The TTL level signals are not used in this setup. https://cache-m2.smarthome.com/manuals/2413Sqs.pdf The 2413S PLM did come with a Network RJ45 connector to DB9 connector cable buried in the box. With only three signals RS232 Out,RS232 In and Common Ground carried through. In this case it is not used.

In the blog post linked to. A reply said theirs was different and only had a 1000uF/25V, 470uF/50V. There is also a 100uF/6.3V. If they looked at the part number of the module. That is the older 2412U power line only model. Many of us started off with the 2412S. Before the 2413S was produced. If you have an original 2413S Hardware V1.0. The board will not look the same as in the photos and the power supply will have rework on it to add to the power supplies connections. A coil and both C7 and C13 are hanging above the board and a wire will be running to the solder side of the module. You may also see C7 and C13 in yours laying on their side. With the leads connecting to the board. The 100uF/50V caps used by Smarthome. Where physically too large to fit directly into the connection pads.

The ISY994i ZW+/IR Pro. Communicates with the PLM by a serial communications signals protocol. You need a 2413S Serial Port PLM not a 2413U USB PLM. If you where strictly ZWave then the PLM would not be needed. As it is only needed for Insteon and X10.
