I don't have one. You may want to with the power off temporarily. Open the unit and then close it again. On the chance the pins on the boards headers where dirty. Where they connect to socket connected to the terminals on the back of the case. Maybe verify the terminals are tight holding the wires to the heating system.

My 2.3 looks the same as your 2.4. C7 and C13 mounted against the main board. With long leads bent at 90 degrees. Mine had a small glob of component glue holding them to the main board. On the Serial Daughter Board. You should find the 2.4 has a TI MAX232EI RS232 chip on it. It meets a stricter ESD specification. Over the chip in the earlier revisions.

I believe there was a 2.4 mentioned in a thread here. My 2.3 was installed on 04/21/2017 and is the revision Smarthome indicated a fix was implemented.

The original capacitor in the line powered side of the supply was a 6.8uF/250 Volt. The 10uF/400 Volt was chosen as the replacement. Higher voltage rating for a better safety margin and capacity for better operation. It is on a full wave rectifier. I don't think it has to have a low ESR but a good ripple rating at the 120 cycle DC from the rectifier. The voltage on the capacitor should be around 180 volts DC. So I would think 350 volts would be fine. C7 and C13 being changed to 100uf/50 volts was an update by Smartlabs. I did not find any other obvious other components when they where changed. I would use the 100uf/50 volt ones to replace the original 10uF/35 volt ones. They are the two in the switching supply output. So they should be a low impedance/ESR type. I have an original V1.0 with the reworked board to add the coil and second capacitor to make it a Pi filter from a capacitor only one. It has 10uF/25 volt ones. 25 volts is only about a 4-5 volt safety margin as the supply is around 20-21 volts.

V1.0 is the original hardware release. I would suspect it is failing. As any 2413S PLM over two years and a few months old. Is prone to power supply failing. Low Link Database Count is also an indication. Unless you only have a few modules. The count is low.

Thanks for the information. Since it looks like the 2411T is on its way out. As the price is now 9.99. I suspect when it is gone. There will be no more. So another device would be needed. The 2411R receiver is no longer being offered for sale either.

I am also disappointed that the Alarm and Siren Modules are not in going to be available. Until a version of 5.? is a Released version or even a fairly stable Beta. I believe they date back even further than the Motion Sensor II. Part of this is Smartlabs problems. Old management didn't seem too willing to share things. Even though I suspect the UDI line of products. Was helping Insteon to be more widely used. I even have a spare base model ISY994i and PLMs to play with but a Alpha is not my cup of tea. Hope new owners Richmond Capital Partners makes thing better but I suspect it may even get worse. They seem to want to to big things with internet connected things. From what their press release indicated.

Where did you find a full 2413 schematic.? There is one for the older 2412 PLMs. There is the power supply area schematic in post #282 of this thread. There is no charge pump in a 2413. The 2412 did have one. I had two with the self destruct firmware in it. Factory reset and you got a 50% chance.The hidden magic smoke was released. As the Charge Pump control FET overheated and failed. Then the coil in the pump burned up. The Zero Crossing has a separate power line derived supply so it has to stay. Keep posting your updates. Interesting theory. I personally would just change the caps and get on with it.

As pointed out in the bulbs users manual. You can't Factory Reset a Insteon Bulb. As it has no linking button. Manual mentions Insteon RF and Power Line. Though my memory says it is RF and you may have to be close enough to the PLM or another Dual Band module to access it. Manual not too clear on linking mode and possible timeout. You may want to move step 1 to between 5 and 6. The bulb may only stays in the linking mode. For a set period of time.

The unregulated +12 Volts DC. That usually is around 20 volts. Is used in the Insteon power line transmitter. You also still need the 120VAC on the input. To power the small power line derived DC supply for the Zero Crossing detection circuit.

The relay output on the UPS. Is it also a dry contact? The users Quick Guide has this in it also. The module has two Opto-Isolated inputs. I1 and I2. You can connect the I1+ and I2+ to the +5 volt terminal of the module. Then the magnetic switch between I1- or I2- terminals and the ground terminal. Then the UPS relay output between the other I1- or I2- terminal and ground. If not too clear. Please ask for more data. Can't help with programming. It also has two Digital Inputs I3 and I4. If you have to have more dry contact inputs. The Guide show you how to use pull up resistors.

As far as I have seen. No release date given. No Beta only Alpha at present. I have had no big issues with a UDI Beta and would install one. I am Leary of an Alpha. Seeing some of the reported issues presently being addressed.

It is not presently supported in released software. Same for the short lived Alert Modules. I have also been waiting since they where released as mine where early purchases. Have not tried the Alpha 5 yet. Though I do have a spare ISY994i and PLM I could play with.

2842-222 is the older Insteon Motion Sensor. I see your link is for an Amazon store seller. That price is high. The present 2844-222 Insteon Motion Sensor II is $39.99 but right now only the Motion On and Off is supported in the latest 4.6.2 released firmware. I understand 5.? will support all the options.

The LNK354GN specification sheet's {post 302 here} typical standby reference schematic. Not exactly the same as Smartlabs design is using. In our D7 position in the feedback circuit. It is a Zener Diode. So it is possible the band is correct for a Zener type diode and not shown correctly in the diagram here. The schematic here appears to have the chip number mislabeled. As the FCC Photos show an LNK354GN and is what I found in mine. A few Smartenit modules base number is 5010. 5010K Powerline Modem maybe? Since it can also have an optional RS485 communications added to the Daughter Board. It is possible it had to have different firmware to handle RS232 and the optional RS485 signals also. I too messed up a 2443 hardware V2 with the same base PLM main board. Found I had pulled out a plated through holes core while removing a capacitor. Had to signal trace and add a insulated wire jumper to fix the busted run.

There is a very long thread here. On the 2413S PLM being repaired and the typical symptoms. http://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/

C7 and C13 are in the switching power supply. Low ESR. C3 120Hz DC ripple, C11 60 Hz half wave DC ripple. I would think ripple current. C8 5VDC from regulator. I don't have an opinion. I believe the ones in the thread are low ESR, 105 degree C or higher and 2000 or more hours rated time.

Look at this wiki entry. http://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:Tools_Menu On the PLM Link Tables section. If you look at the links information. Any one starting with a 02 or 22 is a deleted link. That I believe should be over written at some point. I believe if you do a restore modem on the PLM. The table is rewritten with all the deleted links not put back.

If it is newer than yours. It should be a 2413 base board. Mine from when they where Simplehomenet. Are on the older 2412 base board.

If the EZX10RF is a older hardware model. It was built on the base power line only 2412 main board. The capacitors would be different. As it has a power transformer style power supply. Hope yours is on a base 2413 main board so you can rebuild it.

Glad you got it working. If you had an ESR tester. Good chance C7 and C13 now have high ESR readings. Along with the lower capacity.

I don't know about the safety margin designed in to the switching supply. That outputs around 20 Volts DC. I looked at a 2443, Hardware V2.5 Access Point. That I rebuilt. Same main board no daughter board. Easier to look at. The 5 volt regulator is on the main board. U3 Surface Mounted 78L05L. 78L05 has a maximum current rating of 100mA. ~ 20VDC input 5VDC output. There is another one on the Serial Daughter board. I would expect the Smartenit model also has a 5 volt logic supply on it. To take the ~ 20VDC and convert to 5 volt logic.

C13 is the output side of the Pi filter. So its pads are one option.

Post #282 of this thread. Has a partial schematic on the 2413 main base board. AC input and power supply area. Post #302 has the specification sheet attached for the LNK345GN switching supply chip. If you have troubles finding it. I also found this link in one of the messages here. It was a 2413U so the daughter board is the USB one not the Serial Port one. Main board should be the same. https://1projectaweek.com/blog/2017/6/2/repairing-a-failed-insteon-powerlinc-power-line-modem-plm-2413u

Regulated 12 volts maybe a issue. The output of the power supply is unregulated 12 volts. Closer to about 20 volts. The regulators are 5 volt logic. One on the main board and one on the serial port daughter board. The unregulated is on the 8 pin socket and 8 pin header between the main and daughter boards or one of the unused F1 fuse pads on the daughter board. In the older 2412S F1 was installed and the voltage was on the network style serial port connector of the PLM. Though I suspect its power supply current rating was also more. As it had a power transformer and large filter caps. Not a switcher like the 2413 boards.
