One thing to be real careful with. The +35V side of the capacitor and the +5 Logic supply are tied directly to the Line input from the wall socket. I would also check the 30 Volt Zener diode. That is connected across the 470uF/35V capacitor. In the main 30 Volt DC supply. The earlier hardware version. Where noted for failing or getting warm enough to actually fall off the PCB or blacken the PCB. Your photo looks like the later revision board with a different 30V Zener that may have been an improvement over the older revisions. I replaced the 470uf/35V caps in many of the 2456S3 relay type modules. One started pulsing On and Off at about a 30 cycle rate. One had a shorted 30V Zener that made the module look dead. If they are completely dead. You may also want to check the fuse in the shrink tube. From the Line input pin to the PC Boards Line input connection. This is what is in a older PLM. I believe its frequency was used in many of the Insteon modules. Crystal 22.1184MHz, 18pF Load Y1 Through-hole Recommended: Citizen model CMR309T22.1184MABJTR

I did some looking. I did not find any exact information on a Gredia water flow sensor. I found similar model water flow sensors. Using an Arduno or similar type board. They had a Hall Magnetic Sensor and a rotating magnet. To sense the fluid flow. The Hall Sensor should trigger the Sensor Input of an I/OLinc. The Sensor LED should flash On and Off as the water flows.

VCC(+) to the 5 Volt output terminal of the I/OLinc. So the water flow sensor has to be able to run on +5 volts DC. GND to the GND terminal of the I/OLinc. Signal Output to the Sensor Input terminal of the I/OLinc. The I/OLInc sensor input is designed for a dry closure. That has no voltage on it. It has its own low voltage sensing signal on the S terminal. A 5 volt pulse would probably not do damage to the I/OLinc sensor input. It may still see the 5 volt DC to 0 volt pulses. You mentioned a pulse rate signal on the flow sensors output. The I/OLInc is not designed to be counting pulses. Depending on the pulses speed and duty cycle. It may loose some of the pulses changes or just sit there and miss everything. There is a time period between the sensor input changing and the Insteon power line commands are completed. If the pulses are not too fast. It may have time to send the On and Off commands. A test when connected may show any possible issues. A constant stream of Insteon Signals may cause other communications problems with your set up. The I/OLinc is an earlier designed power line only module, not Dual Band. May need a Dual Band device close enough in some situations.

Thank you for the update. You are not alone. So don't feel bad. The older version labels where even more difficult to see and read correctly. They also had a tendency to fall off. Let us know if you still can't link it.

The pin out on the 2413S PLM Quick Guide. Looks like it is using the signal names from the PC. As its reference. From the serial port schematic. Pin 1 is RS232 signal out to the equipment connected to it. Pin 7 is common ground. Pin 8 is RS232 signal in from the equipment connected to it.

58.58.AE does not look like it is communicating back to the ISY. No INST-SRX Standard Insteon message received back from the ISY asking for the modules information. Like Category and Subcategory. To identify the module. Are you sure you have the correct 6 digit ID. B and 8 sometimes can be misread. 2E.8A.0B is responding "Sun 05/02/2021 08:57:20 AM : [INST-SRX ] 02 50 13.9C.1C 00.00.01 CB 13 00 LTOFFRR(00)" INST-SRX is a message back from the device.

If you have not tried it yet. You may want to open the Event Viewer in Level 3. Then try the process and see what the messages show. You should also be able to save the results in the Clipboard. So you can look at them more and maybe also post here.

The 2448A7 is strictly Insteon RF. So it has to go through another Dual Band device to process the Insteon RF to and from the power lines. Not important to most users but it also does not do any X10 signaling. The PLM uses RS232 for communicating to the outside world. MAX232 or MAX232EI interface chip. So the signals are RS232 swinging + and -. The ISY994i would have to have a matching signal pin out and signals as the PLM. The pin outs and RS232 signal specifications are in the PLM Quick Start Manual. If you don't have one. https://cache-m2.smarthome.com/manuals/2413Sqs.pdf Though most have not found them and tossed the box. There is a RJ45 to standard DB9S serial port cable in the 2413S or 2412S PLM box from the factory. It is only 3 wires being used. Serial In, Serial Out and Ground. Pin 2 was a unregulated 12VDC from the older 2412S as the ISY994i technically could use its power to run. I can ring one out if you need the pin connections. I looked at the output of my spare ISY994i and did not see any signals on its pins for the PLM TTL signals and one seemed to have a termination resistor on it. So I doubt the TTL signals would be used. My thoughts are the 2413S is not abandoned but in very short supply. Due to the pandemic and it is the more popular of the two interfaces. USB or Serial Port. Here is the 2448A7 Quick Start Manual if you want some information on it. http://cache.insteon.com/documentation/2448A7qsg.pdf

A factory reset is recommended for all newly purchased Insteon Modules. It is possible it got shipped with some test links in it and was not reset at the factory. A factory reset clears out any stray links and setting in it.

Did you ever try a replacement power supply? We have seen reports of strange things happening. I had failures on an ISY99i and my present ISY994i. If you are using a 2413S PLM they also have a reputation of failing and strange things happening

Thank you for the update on Steve Lee. He had assisted me a few times and I valued his information. I will miss his assistance and knowledge.

Status 'Fireplace-Sensor' is On . Would only be On as long as you held the button in. Then go Status 'Fireplace-Sensor' is Off. When you released the button.

I would also say. Test the power supply first. It may even have a voltage output on a meter and may quickly die under a normal load. I have had an ISY994i and router with similar symptoms. That a replacement supply corrected.

This is a real long thread on the 2413S PLM and its failures. https://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/ If you look at the label on the back. It should have a Hardware Revision number and a Date Code. I know hardware revisions higher than 2.5 have improved capacitors and a updated serial port. With more protection on the serial signals. I suspect they should be more releasable.

That does sound like a typical Smarthome thing. Sounds like things have not changed much, from when I was a member of the original Developers Group. Had to buy the privilege of membership. Along with an NDA for the documentation and a small set of modules to develop with. This was in the PLC not PLM days. Where you could assemble some code, with SALadIDE and DSM308. Download it into the PLC and it could run disconnected from the computer. Only plus was Insteon was in its infancy and we actually got to interact with Insteon Engineers. That one day just disappeared and all the documentation [though flawed] went public domain for awhile before just disappearing again.

The 2450 I/OLinc can have its Sensor and Ground terminals wired to your switch. It is an earlier design so it is power line only communications. The 2843-222 has a terminal block in it. Where you can wire your switch. It is in parallel with the internal magnetic switch. So when used with the external input. The magnet is not used. It is Insteon RF only and powered by a battery.

Part shortages are becoming an issue for many companies. My Nephew works for a company that makes all kinds of emergency vehicle devices. Like light bars and sirens. He said they are having a big problem with part shortages. I too have seen the automotive industries. Running out of electronic parts and even furloughing some workers.

Does the lamp have an incandescent or dimmable LED bulb? The lamp you used should not have a built in dimmer switch, high-low switch built in or low voltage bulb with a built in power supply.

Since Smarthome backed out of the promised firmware files or programmed controllers. The UDI PLM never saw the light of day. Knowing how UDI designs electronics. I am sure it would be many times more reliable over the 2413 PLM with power supply issues. There is a new Insteon Module in the FCC database that looks like a better replacement for the PLM. Though who knows if it will ever see the production line.

If memory serves me. The 2867-222 Alert and 2868-222 Siren modules. You where not given good information on how they work either. I also understand if new Insteon modules are released and you get no good documentation. They will not be supported. My blame will be on Smartlabs and Richardson Capital Partners. Not UDI!!

I found the message in my SPAM folder tonight.

I have read that Z-Wave has such a security feature. Adding and excluding requires a very close distance between the controller and module itself.

That does not sound good at all. Almost like the old private companies over protective ways. Are still being followed by Richmond Capital Partners. Don't help anyone. Even companies responsible for a portion of their sales and popularity of Insteon. That now seems to be dwindling. Push their HUB with all its limitations and the new APP that from all accounts is half baked and doesn't support half of the modules the they presently sell. I saw it all the way back to the release of Insteon. In the now defunct Developers Group. There was list of potential major manufactures wanting to license the Insteon technology. It quietly disappeared and I understand many are now doing Z-Wave. ?

I would suspect the power supply as a possible thing to look at. A ticket would also get you some answer's. What is the rating of the power supply as seen on its label. Some of my UDI devices came with a 500mA rated supply. The Z-Wave board will pull more current and could be getting close 500mA. I know they are selling 12VDC 1Amp supplies in their online sales page now. Like some other reports here. I too have a power supply get flaky.

What firmware and UI are you using and do they match each other? Is it the Sensor LED that does not go On or the Set LED on the side? The Sensor LED should light when the magnetic switch is closed.
