The ISY994i was discontinued earlier this year. As of 06/01/2023. Purchase modules for a ISY994i was discontinued. Probably why you are getting the error. https://www.universal-devices.com/finalbye994/

My bad. It was a typo. 2457D2 is the one I tried to post about. That the Range Extender is built on.

The V2.6 2434 Access Points are built using the same main board as our 2413S PLM and suffer the same bad capacitor problems we see in the 2413S. I had a pair go bad (No LED or 4 Tap Tests) and rebuilding them with the same information as the 2413S. Made both of them functional again. Not sure if the 2992-222 Range Extenders where in the thread but they also will do a 4 Tap Test and couple signals. By RF and power lines. The 2447D2 Lamplinc is what the Range Extender is built with. Just the dimming circuit removed and it has the same FCC database number.

You may want to look at the 2413U's part number. There was a 2413U and 2413S PLM with the Subcategory used by HouseLinc that was not the same as the one used by the other versions. HouseLinc checked for the different Subcategory ID before it would run. This was the purchased HouseLinc and not the later released free version. You may want to reach out to Insteon Support as a new 2413U should not be reporting it is a special HouseLinc PLM. Though I believe they both work the same just a different ID. The part number would have an H added to it. Like 2413UH for USB or 2413SH for serial port. Though a factory programming error in theory could have the H subcategory and it had a standard part number.

All the 2413S PLM units are Dual Band. Even my V1.0 that needed fly wire changes to the power supply to even be sold. The 2412S was the power line only serial PLM.

One thing to check with USB power. To get the back cover on. They sold a USB charger and a 90 degree connector on the cable. There where some that got a 90 degree style cable but it didn't fit. It seems there are two variations. Cable up or down exiting the connector.

The tap test. Tests the RF and Power Line communications. The flash pattern on the unit receiving the test information. Would indicate communicating and if the sender and receiver are on the same or opposite phase of the homes incoming power feed. In your case I feel communicating on either phase should allow the switch to work.

Power supplies going bad is a problem. I have had as others here also have had. With success of working again with the new supply. My ISY994i was not too reliable. When I rebooted it the LEDs flashed on and off as the supply tried to keep the ISY994i running. A replacement corrected the issue. UDI sold a 12V 2A supply as a spare part.

The four tap test should show you some data. If you look at the manuals for the modules. Some call it a Beacon test. Some also show a flow chart of set button actions and led flash patterns. Many times the four tap test works even if not published in the modules manuals.

If you have any of the older power line only modules. They are I1 and it takes eight power line messages and acknowledgments to change one eight bit address in a module. The hard drives power supply could effect power line communications. I have a LED TV that has a large AC rated capacitor across the power line to eliminate its internal power supply noise from the line. Works well but also sucks up a large part of signals on the line as noise. X10 (frequencies are close with Insteon) XPPF filter on the TV. Also have a Filterlinc on my UPS and another one entertainment system.

You may also want to check your firmware and if real old. Update to the latest released for the now discontinued ISY994i. The needed Z Wave boards for the ISY994i are also gone but sometimes one shows up on a site like Ebay.

The original privately owned management sold to Richardson Capital Partners. Then Richardson Capital Partners did shut down everything abruptly. Former employees and management has restarted the Insteon line and more items are becoming available now. The 2466SW and 2466DW where power line only and discontinued years ago. The 2477D and 2477S should be fine for an ISY994i. They are also Dual Band so you also get RF communications over just the power line. You may want to check the physical dimensions as I believe the 2477S has a larger rated capacity and maybe thicker with the heavier internal relay and power lead gauge.

Was the older PLM a 2413S and the replacement a new 2413S? If the old one was a 2412S then it was power line only and slower link memory. Along with also powering the ISY994i

No I have not seen such an adapter. The connector on the 2413U is the square B style connector. Usually for devices connected to the USB A style controller as the B does not have any +5 volts needed to run a active USB electronic device. As the controller rectangular connector can supply usually up to 1A of +5v and it is negotiated by the devices at discovery.

If you are trying to connect to an ISY994i and a USB 2413U PLM. You need a USB to Serial port adapter. Probably wired strictly to only use the three serial signals on the ISY994i RJ45 style serial connector.

Trying a working power supply sounds like a good test. We have seen (including myself) the power supplies used by the ISY994i failing and a replacement correcting things. In my case it was working poorly and when power cycled didn't have enough power to restart.

I have also seen the Reverse Trigger and the 3:00AM query. Sometimes trigger it to open a garage door.

It will not work. As your assembly is doing. The RJ45 serial connector on the PLM is not the standard serial port signals found on the USB to serial adapter.

All flashing RED. Does sound like power line noise. As pointed out. I too would recommend you check for new or moved electronics. Unplugging devices you suspect are the problem. As Off on modern devices keeps the standby power running and the AC input to the device active. Existing devices that didn't cause issues. Can deteriorate and suddenly start making problems. In my X10 use days. I saw a cheap phone charger. Putting a very strong noise on the power lines. At the X10 line frequency of 120KHz. Killing a system completely.

The Range Extender and the older Access Points. Are not added into the ISY configuration. They pass and receive Insteon commands to and from others. By RF and Power Line. Tested with the built in communications tests and observing the LED flashing patterns on them and Dual Band devices. For communicating and on the same or opposite phase of the power feeding it and a module.

V2.3 Had the Fujucon TY caps for C7 and C13. TI MAX232EI serial chip 2.4 and 2.5 have the same TY caps and MAX232EI. With a new daughter board with a protective network on the two serial signals to the outside world. Have not see a V2.6 so I can't say about any other changes.

Sounds correct. Both new production 2413 PLM's have the same base board electronics. With a different interface to the outside world. Both models should have the same power supply capacitors. The 2413S has a new daughter board. With a better serial chip with better ESD protection and a protective network on the two external serial signals. One will have a subcategory ID for a serial and a different subcategory ID for the USB. If you are going a long distance. I am not sure how you can use USB if the distance is over the USB specification distance.

I have had no ISY994i problems. Except power supplies going bad. Since the ISY994i has a fairly big voltage range. It was easy to get it back in complete working condition. If you are wanting to use the new I3 modules. The ISY994i will not support them as no new firmware is going to happen. The eisy and Polisy have later firmware that will support I3.

The 2413S,2413U and V2 of the Access Points. All use the same base main board. Except V1.0 that had an older designed board with some runs cut and fly wires added to update them for a Pi filter output. They have circuit runs on both sides of the board. Some connected with plating between the top and bottom sides. The capacitors for some places. Have the plated through holes. Use care not to tear the plating out of the holes and killing the unit. C3 and C11 are in power line derived dc supplies and the higher voltage should not effect operations.

C3 is the filter capacitor for the AC Line side of the supply. 450V should be fine and was used by many in the very long thread. Maybe taller but still should not hit anything when mounted. C11 is the filter capacitor for the Zero Crossing sensor and 50V should also be fine. As long as it physically fits and should if the kit was designed for the 2413S PLM. The two that matter the most are C7 and C13 the two in the switching supplies main DC output to run the whole system. Smartlabs tried many different capacitors in those positions. My original V1.0 actually has 10uF 25V with fly wire rework because the originally didn't have the Pi filter on the output. Versions have had 10uF 35V, 100uF 35V and 100uf 50V. In V2.3 they went with 100uF 50V Fujicon TY series capacitors that where supposed to be for switching supplies. V2.5. Now 100uF/50V Fujicon TY capacitor. Parallel to the main board. Maybe with some component fastening glue holding them. Because of the physical size too large to fit directly on the board.
