Sorry I misread your last answer. If the PLM Link Count is still 0. That is definitely a problem. Have you tried a support message to UDI. They are fantastic with their customer support. http://www.universal-devices.com/contact-support/

40 maybe low. It may depend on how many devices you have.

At no point in the procedures. Did you use a Delete Modem (PLM) command?

Most of the Insteon modules. Have one or two 5 pin programming connector and need a programmer connected to change the firmware. Most are also power line derived power supplies. Done incorrectly you could end up landing on the place you sit down or worse electrical shock. My 2456S ApplianceLinc modules have the Logic +5 Volt supply directly connected to the 120 volt AC Line Input . One of the programming pad connections.

I looked at the transformers manual. Does yours have an internal timer adjustment triggered by a photocell to determine when the LED light come on? Maybe an option as manual was not 100% clear. I did see the optional output for added mechanical timers. I did see it could be used with an AC dimmer on the AC Line input. Rated to be used with inductive loads.

I have seen with my PLM from Amazon. Depending on when I searched. The default sellers page sometime was different. depending on when I did the search.

If the mechanical timers could be powered from the outlet on the side. 120 volts AC sounds more like it. Where the timers controlling the AC line Input to the transformer or switching the 12 volts to the lights. Controlling the AC input sounds more logical. Before trying a SwitchLinc Dimmer. I would check the transformers specifications ans verify they can be controlled by a dimmer on the 120 volt primary input.

If you use Amazon. Check if it is an Amazon sold and shipped or a Amazon Marketplace vendor and shipped by Amazon. I got a 2413S PLM sold and shipped by Amazon. Was the latest V2.3 hardware. I have seen reports here some got Amazon Marketplace PLMs and they were an older V2.2. Warranty may also bee different if the vendor is not an authorized distributor.

The 2457D2 LampLinc is a 120 VAC module. You where using the 12 VAC on the low voltage side of the transformer to run the LampLinc and it actually worked? It has one of the small switching ICs in it so I guess it maybe possible. I suspect it was using Insteon RF signals from a nearby Dual Band device. As I doubt the Insteon power line commands making it through the transformer. It maybe damaged. 12 volt lights may draw more current at a lower voltage. Take and plug a standard 120 volt light in it and see how it acts. In a 120 volt outlet. With no Load on the output outlet. If you push the On button does it stay On or cycle back Off? You could try a factory reset and see if anything changes. Do you know if the lighting transformer is made to work with a dimmer?

Also when powering back up. Power up the PLM first so it can fully initialize before powering up the ISY994i.

I just tested my ISY99i. Firmware 3.3.10. No PLM. It went into Safe Mode as we thought. I think in the Safe Mode. The Network add on may not do much.

If you do a Show PLM Link Table test in the Tools Diagnostics a few times. If it is almost empty. That would be another sign the PLM has power supply issues. PLM Info/Status if it shows safe mode also can be an indicator. Long thread here on how the PLM may fail and how some have fixed theirs with new capacitors. http://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/

The 2474DWH is a two wire dimmer. Steals its power through the Load. Load has to be an Incandescent or 120 Volt equivalent halogen bulb. It will not work with anything else. Like CFL, LED bulbs, inductive things like motors. 2477D can be used as a controller for other Insteon Modules. Supplying the AC Line {Black} and Neutral {White} power connections. Can control a Load if the Red wire is connected and not capped off.

Both the Alert Module and now the Siren Module. Go way back before the takeover. They still are not supported properly due to Smartlabs not giving the needed information in a timely manner. I too lately have seen Smartlabs reluctance to give UDI the needed information. I have reservation on their relationship myself.

The 2992-222 Range Extender. Is actually a 2457D2 Lamplinc with out the dimming parts and probably difference firmware. A full feature Dual Band module is not much more costly and it allows you more options.

Thank you for the heads up on how crafty the Spammers are now getting. I will have to look more closely in forums I attend or moderate.

Does not have to be something new. Can be something moved to a different location. Dual Band device like a 2443 Access Point going south and no longer getting the Insteon commands to the other power line. If you have any Access Points see if they are hardware 2.0 or higher. They have the same power supply issues as the 2413S PLMs. Though the Scene showing off and the lights are On maybe a clue.

There are also a few White Papers on the Insteon.com web site. http://www.insteon.com/technology/#documentation

Some surge suppressors have a noise filter in them also. So some may absorb the Insteon Power Line Commands as noise. I had some with an across an AC power line rated .1uf 250VAC capacitor in them absorb both X10 and Insteon power line commands. Lucky for me they where on a small PCB and could easily be removed.

Even closer. RF signals can be strange, If the new location has any metal in the wall or the RF paths no longer are in line with each other. Things may not work as well. Dual Band Switches in a metal electrical box. Can have their RF distance and communications direction limited by the metal. Does not help that the Insteon RF antennas are in the BACK of the module. Closest to back back of a metal electrical box.

When you moved it to a different location. You changed things both power line and RF. You may have the PLM on a different circuit. One with noise makers or signal absobers. If the PLM is now on the other half of the house wiring. The power line signals may now have an issue getting to where they use to. Dual Band modules along with the Range Extenders can act as coupling between the incoming power lines. How new are your switches? Most presently sold Insteon Modules are Dual Band. The 2441V is strictly an Insteon RF device. So it has to be in RF range of the PLM or another Dual Band Module to do the Insteon RF communications.

Found by a search. Not too sure if this will help. It has some information on what they call "Smart Hops" http://cache.insteon.com/developer/i2CSdev-022012-en.pdf

Look at the starting post for 4.6.2 firmware. http://forum.universal-devices.com/topic/22000-release-462-is-now-official/ The firmware update does not update the UI or Dashboard. The post gives you the link to the new UI and how to properly update it. It also gives the link to the 4.6.2 Dashboard if you use it.

I think I gave you some information that maybe not be 100% correct. I now remember that I was swapping 2412S/U PLM Daughter Boards and 2414S/U PLC Daughter Boards. In the 2412S/U the swap was fine. I imagine the 2413S/U {same basic daughter boards with a faster speed EEPROM memory chip} would be OK also. Even the 2414S serial board would work in the 2412S PLM. I have some early 2412S PLM unit with 2414S Serial Daughter Boards in them. The added RTC clock chip and battery where ignored along with the much larger memory size. The USB board between a 2414U and 2412U would not work. As they have a different baud rate.

The 2413UH is the purchased HouseLinc version of the PLM. It has a different Subcategory ID number in the main boards firmware. To the ISY994i it may not matter. It did if you tried to use a 2413U with the purchased version of HouseLinc. I have swapped Serial and USB PLM Daughter Boards and for me they worked. It may not work but should not emit the magic electronic smoke.
