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.

Well new modules in development maybe possible. Usually no advanced notice. Except when a prerelease sale is in place. We also don't know completely. What Richmond Capital Partners is going to do with Smarthome and Smartlabs. I have seen some of the devices that look like slow sellers. Get discontinued and sold real cheap to clear them out.

The Smartenit {Simplehomenet} devices are built on a base 2413 module. Purchased from Smartlabs. Older ones on the 2412 base module. I have seen reports of hardware revision 2.4 lately. Mine is a 2.3. There are a many reputable capacitor manufacturers carried by both Mouser and DigiKey. I can look up a few if you want. All the manufacturers mentioned in this thread should be reputable ones, C7 and C13 are the two in the unregulated 12 volt power supply. Normally around 20 volts. They are the two that should be rated for a switching power supply. Different definitions by between manufacturers. Low ESR or Low Impedance is frequently pointed out. If your C7 and C13 are in older hardware. They was a different value in them. The present ones in my V2.3 is 100uF/50V. Maybe even bigger now, We have used 100uF/50V in them. Temperature rating of 105C or higher, Rated life of 2000 Hours or more. I have seen 5000 or even 6000 hours. Every 10C below the maximum rating exponentially extends their life. You may want to look at their size. I have seen some values with two sizes. One taller with a smaller diameter and the other a shorter one and a larger diameter.

There is a thread here on substituting an external probe for the internal probe. So you can use it for remote readings but you then can't read the temperature at the 2441ZTH. http://forum.universal-devices.com/topic/9152-how-to-monitor-water-temp-via-isy-and-catch-more-fish/?hl=2441zth

Same thing for the 2443 Access Points. The Range Extender replaced.

May have been the Heartbeat they send at around a 24 hour interval.

It is a firmware change UDI does remotely. Also adds a larger number of scenes the nodes you can have. Over the standard model. In addition to the Automatic writes On or Off. For both AC powered modules and Battery devices. Gave an incorrect choice. It is Purchase Modules not Manage Modules. To see what you have and what can be added. Manage Modules see if the installed ones are up to date.

You can purchase it directly from the Administrative Console. Help Tab Manage. Modules Choice. It tells you what options are installed and what you can purchase. It is a update you purchase and then UDI enables it directly. Some like the IR addition also send you a small IR board you have to install yourself.

Factory Reset on Insteon modules. Can also depend on the age and firmware in the modules. Like the original 2476S Relay Switch. Has no Air Gap Switch and a completely different Factory Reset procedure. Some used the Set Button power cycle for reset with beeper or before beeper. The latest firmware moved to the Flow Chart and LED colors sequences. Also seem the older model/firmware manuals have disappeared from the web. So it can be hard to find the correct procedure.

Sounds like the ISY99i is a Pro model and the ISY994i is not a Pro model. Did you exchange the ISY99i with an Upgrade to ISY994i? If it was an upgrade. You may want to see if UDI has any options to move the Pro from the ISY99i to the ISY994i. Try clicking on the module and wake it up. Then see if there is a Write Updates choice shown.

If the power strip has some surge suppression and a capacitor across the AC Line input. It maybe absorbing the Insteon power line signals. So can computing equipment, UPS units and other electronic devices. Some times unplugging things and testing again. Can find the offender. So the plug in module maybe using Insteon RF commands if the power line ones are not stable. The outlet in the wall box maybe not also receiving the Insteon RF. As RF sometimes can be spotty. FilterLinc has to go on the device making the power line noise or signal sucking. I have one on my UPS in the filtered outlet and my PLM in the unfiltered outlet on the front.

The new ISY994i unit will have a different UUID from the original ISY994i. You may have to update the settings Stu pointed out.

Any particular modules in mind? Some maybe limitations in the modules firmware. Local Ramp Rate, Scene Ramp Rate?

Yes Though the RF distance between devices. Can be effected by distance, what maybe between them and if the 2477D is in a metal electrical box.

I have not seen anyone extending the internal temperature sensor out side the case. It should work. One thing to do if you try it. The sensor has bare leads on it as it normally is inside the case. I would put some insulated tubing on the bare leads and some shrink tube where the short wires are soldered to it.

Good to hear of another successful repair.
