Besides the possible EOL Resistor. There is probably a sensing current or voltage on the switch from the security system. That can mess up the 2483 that expects a dry contact switch and has its own sensing current. Separate switch maybe needed. One for the security system and another one for the 2483.

Is there a different number of the LED bulbs between the ones that work and not work? I have seen some manufacturers tested dimmer switch charts. Show a different minimum number of bulbs needed to work between different dimmer models.

I have found that some combination of dimmable LED bulbs and dimmers don't play well together. You may want to test a different LED bulb and see if it worked better. Many LED bulb manufacturers will have a list of tested dimmers for their bulbs. Though almost never are any automation devices tested. Off hand do you have the model and manufacturer of the LED Bulbs in question? I have tested some brands of dimmable LED bulbs with real old 2476D Switchlinc Dimmers. Most worked fine. Some pulsed at 100% or one dim level below 100%.

This may give you some information. http://wiki.universal-devices.com/index ... r_ISY-994i

Glad you found it. All it takes is one major offender to mess things up and sometimes finding it requires lots of leg work.

The ISY994i may come with a external power supply in the box. Mine did. I am not sure if the 2412S with v.52 firmware. Was the older 417 link database or the >2000 link database. The larger database had issues with more then 800 links if my aging memory is correct.

Did you verify the LED Bulbs where rated to be used on a dimmer type switch? Not all of them are. If the LED bulbs where not rated for a dimmer. That could be the problem. I know other users have LED bulbs rated to be on a dimmer. Working with Insteon Switchlinc Dimmers and LampLincs.

Many of the new universal Insteon Modules. Are 100-277 VAC and 50/60 Cycles. If the user has the new universal modules. The module sets itself up for 50 or 60 cycles at power up. Unfortunately as you pointed out. The PLM is strictly 60 cycles. Though we keep pushing for a new universal power PLM.

On my Windows XP computer. Clearing the Java Cache including applications. Removed the Desktop Icons. In the Java Control Panel. I found them in the deleted applications tab.

Been awhile since I used my ISY26. I did find this in the UDI wiki. http://wiki.universal-devices.com/index ... inks_Table

In the Tools tab Diagnostic Choice PLM Info/Status will show if it is connected and its ID.

You mean the X10SC503 that was a ControLinc with the labels removed? Manually link the ControlLinc to a module in your system. In diagnostics Show device Link Tables. Then do a compare and see the added links ID. You could then rewrite the devices link table and it should remove the unknown link from the ControLinc added to the module.

Glad you found them. I have found some very informative.

No the PLM on the ISY994i's serial port is detected when the ISY994i boots up. One hint is make sure the PLM is powered up first. So it is avilable to be detected when the ISY994i powers up. You will find all kinds of information in the UDI wiki and here. Like full users manuals and tips on doing things. http://wiki.universal-devices.com/index ... =Main_Page

Yes Smartlabs is the only game in town these days. The list of manufacturers interested in Insteon. The early Developers where given. Quietly disappeared and was never seen again. Though quite a long thread. You may find some of the information in ELA's findings interesting. I believe he customized a PLM to do signal tests. For personal use only. As I could see Smartlabs getting testy if he offered it to others. viewtopic.php?f=28&t=5923

In the the Press Release from Smartlabs. They indicated three phase was now officially supported. I believe the RF from the other Access Points is resynchronized to the Zero Crossing before being sent on the phase the Access Point is connected to.

Are you looking at the Details or Summery list? I do remember someone having some problems with getting the files, but I don't remember what the fix was.

My thoughts are if there is power line noise on the X10 120KHz power line signal. There could also be noise on the 131.65KHz Insteon power line frequency. Both X10 and Insteon use the Zero Crossing part of the AC waveform for timing. Noise is not always the problem. A problem electrical device may not be making any power line noise but its internal power line filters. That keep its electronics noise from getting onto the power lines. Is absorbing the Insteon power line signals as noise.

I have been a Community Organizer on the X10 forums with Jeff for many years. He knows what he is talking about. He will not try and sell his wares to anyone. If he didn't think it was a good choice. I still have a mixed system. Mostly Insteon but with an X10 address in my modules. As I still like to control individual modules with a HR12A Sixteen Address Palm Pad Remote. Also no real good Insteon Chime Module and most work around are just that. Again mostly X10 oriented but some can also be Insteon related. He has a great set of tutorials on noise, phase coupling and signal suckers. I found the ones on the Chinese Cell Phone Charger and CFL noise very interesting. http://jvde.us/x10_troubleshooting.htm I still have one of the ELK ESM1 signal meters shown in the cell phone charger noise tutorial. I also still have an Smarthome X10 TesterLinc Signal Tester. I believe Insteon just shows as noise and bad X10 messages detected.

Three phase power. You have to have at least one Access Point or Dual Band Device on each phase and verified communicating. To have three phase work. http://www.smarthome.com/pr12-02.html

I don't believe any special permissions are needed. I pick Detail for the choice and then accept the warning that the FCC is not responsible if the vendors file have a virus. My version of IE give me a page has mixed secure and insecure contents. I say no to display secure parts only. Then the files are listed for that ID number. I then click on the choice and let them open. I save them after they load. With a new name as all of the are called the same Get Appliacation Attachment.pdf

larryllix and anyone else that would like to see internal and external photos of many of the Insteon devices that use RF. They are in the FCC Database. Along with test results for compliance to FCC requirements. https://apps.fcc.gov/oetcf/eas/reports/ ... Search.cfm In the Details choice after finding the device you are interested in. Grantee Code:SBP Product Code: 2441T for the thermostat. 2441ZT for the wireless thermostat. 2441V for the older dongle that plugged into the Venstar T1700,T1800 and T1900 If you just input the Grantee:SBP and search. It will find all of the devices in the database that are from Smartlabs. Including the hardware version 2 2443 Access Points, 2413 series PLMs, LED Light Bulbs, etc.

If you want to replace a module with a similar new module. Add it to your setup. Then click on the old module and a list of replacements will be listed. Including the new one or any other one that is suitable. Relay and Dimmable devices are not suitable exchanges and would not be listed in the choice of replacements. http://wiki.universal-devices.com/index ... ace...with http://wiki.universal-devices.com/index ... g_a_Device

I have a JV Engineering XTBM. It can measure noise up to .99 volts and X10 signals up to 9.99 volts. http://jvde.us/xtb/XTBM.pdf The JV Engineering devices are aware of Insteon power line signal protocol. The XTBM in my home will display some Insteon messages. Though since the signal it is showing may have been passed on from the device you wanted to see. I bounces around with signal levels. I mostly check for signal suckers with an X10 signal. As my XTB-IIR Repeater/Coupler hits my power lines with over a ten volt signal and respects Insteon. I can then plug in a questionable device and see how much signal drop is shown on my XTBM. Checking for noise. I just try different locations in the home and observe the noise readings. While connecting and disconnecting suspected devices. I don't have the latest firmware in it. So I don't have the optional P1 being sent on a nose reduction to cloud things up. Though it can be disabled.
