The kits maybe an easier way to go. As electronic components are also showing shortages now. Looks like it has the improved capacitors for the original C7 and C13, 10uF/50V are the replacements. Smarthome tried different size capacitors in an attempt to get better reliability. You may find 10/35V, 100uF/35V or 100uF/50V. In C7 and C13 positions. Good quality 10uF/50V C7 and C13 would probably be fine. If by chance you have an original V1.0. It is different. The main board only had one capacitor position so their is rework on the board and C7 C13 and the coil are hanging off of the board with a wire going to the back of the board.

A recent look didn't see any of the 2413S PLM on Ebay. I didn't even see any of the older 2412S power line only versions. If someone does see one. Remember they had a power supply issue and some sellers over rate the items working condition.

Thank you for the link. I have most of them. Through web searches and links. Having all of them in one place will be a help to many users.

It will be interesting. To see how long it is until the 2413S PLM is again in stock. Or both the 2413S and 2413U are replaced with the new model in the FCC Database. Universal AC power, larger and faster Link Database , the serial version can supply voltage to run the ISY994i through the serial connector. Like the older 2412S could. Stronger power line transmitter and receiver. Better RF section.

Using an Ethernet type cable. Doing RS232 Serial is not a typical thing we see. You are not alone in thinking it was Ethernet. Unfortunately the 2413S is sold out. So you are not alone in trying to locate one. Some have tried some workarounds with out much success. Like using the 2413U USB. One user has used a Raspberry Pi and some converters to do it but it is not a simple plug and play thing.

The 2413S PLM used with the ISY994i. Is not an Ethernet module. It is a RS232 Serial signal interface. Although the 2413S PLM has a RJ45 style jack on it as does the ISY994i. . A hold over from the earlier Smarthome products. The signals on it are RS232 Serial. The signal pin outs are on the guide in the 2413S PLMs box. Along with a RJ45 to DB9S cable. Not used in the ISY994i setup. The 2413U PLM you have seen. Is a PLM with a USB interface in it. It will not work with an ISY994i. The 2413S has been out of stock for awhile now and electronic part shortages will probably have it out of stock in the near future. The 2413U may still be in stock for now. My thoughts are it was a slower seller and was still in stock.

I have a power strip with built in surge suppressors. It was also designed to filter the AC line. The filter is an across the power line rated .1uF cap in it. That I removed to stop the signal sucking. I also have portable AC. When connected to the line. One of my power line only 2456S3 ApplianceLinc modules is intermittent. A Dual Band module in its pass through outlet on the front seems to have cured it.

The receiving circuits in any Insteon Module. When not transmitting can absorb a small amount of the power line signals. So the one not sending a command. Could absorb a small amount of Insteon signal. If there is a marginal signal path. It could be enough to change things. Especially if it was a system with power line only modules {Like Me ? } As for stacking modules. Only the older designed modules have a pass through outlet. Like the 2450 I/OLinc. Smarthome did warn about stacking them and I can verify stacking the 2456S3 Appliance modules increases their temperature. A 2413S PLM is warm enough as is. I stacked an older revision on top of a 2456S3 for a Dual Band sender receiver only and the back got very warm. I don't mind stacking some modules but never a normally warm module like a 2413S PLM.

If the modules are the power line only type. It is possible the two PLMs in one socket, are absorbing some of each others power line signals. If one or both are the 2412 power line only models. That could also be a factor.

Thank you. My old eyes missed it.

If anyone is interested. The link Mr Bill provided to the wall switch. The specification information shows it has an FCC ID SBP WALL. The internal photos, external photos, tests and a uses manual are all listed and you can download them. As I have done. I did not see a six digit Insteon ID on it but that doesn't mean it doesn't use one.

UDI has posted. If they are not given the proper information. To have an ISY994i properly control them. They will not be supported. Just existing Insteon modules.

This is a long shot. The Insteon 2822-292. Is the 2450 I/OLinc in a Retail Box. Sold by some automation dealers.

Guess it would be too hopeful. That the power line only I/OLinc was going to be replaced by a nice Dual Band one with more features. It does look to me that they are going in a direction not boosting Insteon.

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

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.

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.

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.
