The PLM is not on the same circuit as your computing equipment? Computing equipment and UPS units are typical noise makers or signal absorbers. For Insteon power line signals I use a FilterLinc on mine. PLM in the front unfiltered pass through outlet and the UPS with computing equipment. On the filtered outlet.

It should but with one caution. The Insteon RF signal from the Range Extender. Has to reach one of the dual band devices you have installed presently.

Make sure the magnet is within normal sensing range of the sensor. You may want to GENTLY tap on the switch and see if it is intermittently changing state and verify the connections are tight on the IOLinc's connection block.

If the X10 controller is still being used. It is also possible it is also sending an X10 power line command and stepping on the X10 command from the ISY controller.

Have you had a chance yet. To try the X10 receiver you are using with the HR12. In the same place as the PLM? Is your PLM on the same circuit as the computing equipment, surge strip, UPS? Do you have any X10 Phase Couplers or X10 Coupler Repeaters between the incoming Lines? If so what type and model?

Restore PLM probably would not do much. Now when you get the new PLM make sure you follow the proper procedure or all of your Insteon devices will have the old PLM ID in them and not work correctly. Power down the ISY994i and PLM. Connect the new PLM to the ISY994i Power up the PLM. Power Up the ISY994i and let it fully boot. If you have the Pro version. You can turn off Automatic Writes to Battery Devices and then individually do them. Restore PLM to change all the Insteon Modules with the new PLM ID. 220 Volt X10 modules are a special case. You have to have the X10 signal on both incoming line wires. Depending on exact conditions it is possible the X10 signal is being coupled, out of phase, between the lines and canceling the signal between them. Jeff's tutorial on phase coupling. Page 8 touches on the 220 volt signal possibilities. http://jvde.us/x10/x10_couplers.pdf

The X10 cross reference sheet. Shows the Leviton 6371-1 and X10Pro can replace each other. Though the Leviton has InteliSense AGC for better operation in noisy environments. That the XPS2 may not have.

If you put the X10 Transceiver in the SAME outlet as the PLM. Does the HR12A Palm Pad still control the switch? The older model TM751 or RR501 Transceivers also have a stronger output than the 2413S PLM. So that also may cause differences. Depending on how old your transceivers are. Sometimes works and other times does not work. Sounds like you have an X10 power line signal issue. Since Insteon devices have a power line transmitter in them. They do absorb some power line signals. Insteon is passed along by the modules X10 is not. Some users have found as more Insteon devices are added. Insteon improves and X10 gets worse.

Have you tested with the X10 controller in the same location as the ISY994is PLM? That would see if you may have an X10 signal issue from the PLM's location to the 220V X10 switch.

You are welcome. I didn't do a 100% inspection of my 2.1. So it is possible other components may have been used.

If you have any 2443 Hardware 2 and above Access Points. Test them with the Communications Tests. I had two get flaky. One had a dim LED and the other would not send or receive in the Communications tests. Same Base PLM board with problem power supply caps is also used in the V2 Access Points. I rebuilt them and they are again 100%.

I see Lee Fleishman. On page one of the PLM repair thread. Reported opening a brand new hardware 1.C and it had the new C7 and C13. http://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/

Well my fading memory maybe failing. I thought I had seen the transmit LED for the phases flash at times with Insteon Message but maybe it was the received LED.

The 2413S I am using with my ISY994i. Is a Hardware 2.1 with 9E Firmware. It is not one of those vaguely referenced. Older 2242-222 HUBs. With the network PCB replaced by a Serial Daughter Board from a 2413S. My older Hardware 1.B Firmware 9B still has the original C7 and C13 capacitors.

Michel, Thank you for the hardware version where the later caps where included. I had thought it was 2.? but that may have been where they updated the firmware. For a possible fix for the All On Syndrome.

The module would have to be reworked for Insteon. The 4826 module in your photo is strictly an X10 Coupler Repeater and had a reputation of sometimes corrupting Insteon power line signals. By thinking the tail end of an Insteon message was an X10 one and sending an X10 message. The 4816 was a similar looking one with no active electronics in it. Just a series LC network between the two Lines. I changed the small coil in one of them to tune it closer to the Insteon power line frequency but it didn't matter that much. I believe 2406H has the same coil and capacitor in it. In the case wired directly to the breakers.

http://forum.universal-devices.com/topic/16285-release-438-rc4-is-now-available/ There is a no PLM version and with PLM version of the firmware in the above release post.

If it is a 2413S Dual Band PLM. It has a LED on the right side that lights Green and turns Red during some signal processing. The older 2412S also has a LED on its right side. If you are running a 2413S and its is around two years old. It probably is failing. They have a reputation of failing just after the two year warranty is expired. Many threads here. Along with the Smarthome and Insteon Forums. One of the early signs is LED dim or out and power cycling sometimes restores it to run for a short time longer. I had one last about one extra week after power cycling. Another sign will be the link database is empty or has only a few entries. If your PLM is a 2413S and around two years old. You may want to think about getting a replacement. Before it dies again.

The Insteon Developers Guide also has information in it. http://cache.insteon.com/developer/developer-guide-022009-en.pdf Power Line Modem Guide also has details. http://cache.insteon.com/developer/2413dev-042007-en.pdf The I2CS Messaging is in this I2CS Developers Guide. http://cache.insteon.com/developer/i2CSdev-022012-en.pdf

I would also say try a new bulb. Electronics in LED Bulbs have been known to change or go bad after running for awhile. If the reset SwitchLinc and new bulb act the same. It does sound like the SwitchLinc may have failed or you have developed a poor connection in the wiring.

Where the PLM is located and what obstacles are in its RF path can also effect the distance. If you look at the carefully worded specifications. It always gives you the maximum distances. It is in open space with NO obstacles in the RF path. My 2413S can only reach one Access Point and no Dual Band module. Due to where it is mounted.

You would need an X10 TM751 or RR501 X10 transceiver to receive the X10 RF command from the Homelink Buttons and send a X10 power line signal the ISY994i could process. I looked at the Skylink 318TR web page and instruction manual. It looks like it has a dry contact output. Normally connected across the original push button for the garage door. A dry contact output should trigger an I/OLinc's Sensor Input. If you decide to use it and not the Homelink buttons built into the car. Since it simulates a manual button push. It will close the Sensor Input to send an On command then shortly send an Off when it opens. Your program or scene would have to handle the commands. http://www.skylinkstore.com/store/us/us-universal-garage-door-accessories/fixed-code-control-kits/garage-door-conversion-kit.html http://www.skylinkhome.com/docs/manuals/ha/318TR_manual_050427.pdf

The HomeLink lamp controls are X10 as Stu pointed out. There customer web site even shows the X10 Transceiver and LM465 Lamp Modules. http://www.homelink.com/about/lighting

You may want to submit a contact form to UDI. http://www.universal-devices.com/contact-support/ They can remotely connect to your setup and see exactly what is happening.

Power down both the PLM and ISY994i Power up the PLM then the ISY994i You must use the Restore Modem (PLM) choice in the File Menu. To get the IDs correct in the modules and new PLM. There is information on how to do this. On this UDI Wiki Page. http://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:File_Menu&redirect=no
