Is it the older power line only 2456D or the newer 2457D dual band model? If it is the older model 2456D2 or 2456D3. I would think it maybe starting to fail. I had the On/Off model 2456S3 starting to pulse on and off at about a 1 second cycle. Was a bad capacitor in the unit. I don't have much experience with the 2457D modules. It could be starting to get flaky.

Wrong UI version. The ISY Launcher. Picks the correct UI for the firmware installed. https://forum.universal-devices.com/topic/24381-isy-launcher/?tab=comments#comment-242590

There is lots of information, tutorials and videos in the UDI wiki. Including the ISY Cookbook. https://wiki.universal-devices.com/index.php?title=Main_Page

The I/OLinc modules. Have the same switching power supply chip as the 2413 line of PLMs. So I would think they may also have power supply issues and acting strange if the supply is getting flaky. In my 2450 modules. Smarthome tried a few different capacitors in the supply to try and improve reliability. Not a Pi style filter just a single C7. My V1.0 units where 10uF/25V close to the supplies output voltage. A 10uF/50V in a V1.8. Latest I have is a 220uF/50V in a V2.3

If you did not Factory Reset the module first. We have seen some modules having test addresses in them from the factory. So if you used add existing links. I would also think it maybe a link for a module not in your setup.

On my later purchased ISY994i. One of the case mounting screws is under the ISY994i label with is Bar Coded part number. The earlier one I have there was no label over one of the case mounting screws. So it is very possible. You have a label covering one of the case mounting screws.

Do you have a Z-Wave enabled ISY904i? The modules in the older post are Z-Wave devices. You could use a ELK9200 heavy duty 220 Volts contactor in its enclosure. https://www.elkproducts.com/product-catalog/elk-9200-heavy-duty-relay-contactor Controlled by a 120Volt Insteon plug in module or a switch. Or a contactor controlled by an Insteon Module.

No it will not work. It is a USB adapter. You need a 2413S serial PLM. To connect to the ISY994i's serial port jack.

When I just looked. The Z-Wave Plus board is showing in the UDI Store and not marked Back Ordered. If you find another dealer with it. Make sure it is not an earlier older version board.

I suspect the Smartenit (Simplehomenet) modules may have had a firmware that worked with their custom daughter boards. I have seen the later 2413 main boards not boot without a daughter board on it. Like the earlier ones did. So another thought would be the Smartenit board didn't satisfy the base 2413 board.

An extra MOV can't hurt. On the AC input pin screws. You won't even have to modify the PCB.

Did a short test. Only USB PLM I have is a V3.1 2412U. I took the Serial Board from a rebuilt V1.5 2413S PLM. Installed the Serial Board in the 2412 chassis. Using a PLM test routine in DockLight Scripting. It worked fine. Sent and received X10 commands. Acted correctly for other commands. Only exception is it reported it was a Category 03 Subcategory 0B USB version PLM not the 03 11 Serial PLM. I don't think an ISY994i uses the PLM type ID. Just the reported six digit Insteon ID and firmware version so it probably would work OK. A USB to serial adapter would not work as pointed out. A USB PLM has a 'B' USB Jack not a 'A' USB plug on a USB to serial adapter.

From your PCB backside photo. The firmware label on the main controller is 85. The presently being sold V2.5 is 9E. So a new one would also get you later firmware and a freshly manufactured 2413S. The C7 and C13 caps are now designed to be in switching power supplies. It also will have the new Serial Interface Daughter Board. It has a better serial interface chip. That has a better ESD protection rating and a protection network is on the serial signals to the outside world.

That is a original hardware design V1.0. It may also be in a few other early 2413 PLM revision main boards. I have only seen a V1.0 myself. It has hanging parts and rework on it. (C7 and C13 and an added coil). The original designed board. Looks like it did not have a pi filter on the DC supply. Just a single capacitor for a filter. The pi filter is on the later designed PCB. So no hanging components or fly wires from the front of the PCB to the back. Let us know what capacitor values you find in yours. I had one with a pair of 10uF/25VDC capacitors in mine. In the supply that can be 20.5VDC.

You may want to start by get some information in the UDI WIKI. https://wiki.universal-devices.com/index.php?title=Main_Page There are some very good manuals, tutorials, setup videos and the ISY Cookbook there.

Use the R and W terminals of the AUBE and connect to the NO and Common relay output terminals. If you used NC and Common then the heat would normally be on and off when you turned On the relay in the IO/Linc The C terminal on the AUBE is not used in this case. It could provide power to a thermostat that used the 24VAC common for power.

Oh I missed that. Thanks for pointing out the box to try and click on.

Yes try and open it.

In the My Account. The screen you posted earlier. On the registered ISY product line. Try clicking on the Action Area. Modules tab. The purchase modules choice in the Help tab. No longer shows you options to add or delete modules. It just takes you to your account information.

So when you clicked on the Modules Tab. The Z-Wave option was not listed?

Are the Insteon modules On-Off relay or Insteon Dimmer modules. Are the LED bulbs dimmable if you are using Insteon Dimmer modules? I have seen posts in the Smarthome and Insteon.com Forums on LED bulbs flickering on power line traffic. One person found using a 2477D dimmer switch on the LED bulb worked better than a dimmer type KPL. Some say different brands of LED bulbs work better than others.

Thank you for the UPDATE. It may help others with similar issues. Good to read you are back in business.

On the V2 2443 Access Points. The built in communications tests ( 4 Tap Test) may also fail or act strange. I have swapped daughter boards in the older 2414 PLC and they worked. I can't say about the PLMs. I suspect they may work but I have no USB 2413 PLM daughter board. They would probably have the USB Category and Subcategory ID if the ID was requested. I know Smplehomenet was selling surplus 2412 units on EBay. They would put a serial or USB card in them your choice. Just for giggles. I may try the one 2412U daughter board in a 2413S PLM.

Tools, Diagnostics, System Status also has some memory information in it.

Help Tab. About choice. Will give you the firmware, UI, model of ISY994i, memory information and any Optional modules installed. If you have the PRO version it will be shown as a PRO. Also if you have a Disable Automatic writes and Disable Automatic writes to Battery Operated devices features. That is only in the PRO version. The non PRO models limit the number of programs and scenes it can use. If you hit the limits. You can't add more programs and scenes. I can't find the limits in my notes. You can purchase the PRO optional module if needed. It is pure software change. You purchase it and UDI enables it remotely. You may want to see what others can contribute to your problem.
