I would first focus on the low voltage lighting. If the transformer is not hard wired then you may want to try either a filterlinc between the transformer and the line, or substitute the low voltage out for a led or incandescent load to see if that eliminates the problem.

chacvhdog, Did you run diagnostics on the devices other than the motion sensor? What type of bulbs are you using in the fixtures? What type of devices are you using, are they dual band?

The replace has to be a similar device, dimmer switch with a dimmer switch, etc.

You either have a combinations issue, I.e. either noise on the powerline or poor signal or you may have some bad links in the devices that are not responding.. Run a diagnostics / compare on the device(s) that are not responding. If all is OK then you should focus on the communication issue. Have you added any new electronics abut the time the problem started. Do you have dual band devices in close proximity to your motion sensors?

If your replacing a switch with the same kind, first link the new switch in the ISY then right click on the old switch and click on "replace...."

There's a current version of the ISY manual, for 4.3.26, at http://www.universal-devices.com/docs/production/ISY%20User%20Guide%204.2.8.pdf

The lights indicate that the ISY is unable to communicate with your Ethernet network. Check your cables and try rebooting your router

Which lights are on / blinking on the ISY

Doesn't the "automatic write to battery operated devices" option in the ISY pro do the same as the write update program?

Maybe you should give the Smithsonian a call to see if they want it. They could put it in a display case next to the Wright Brothers plane.

There are two basically two types of LED bulbs, those with a built in driver and those without a driver. The bulbs with a well designed driver circuit offer better compatibility with various dimmers. The attached file expands on the driver technology. understanding-led-drivers.pdf

Is this what you're looking for? ISY Program execution order.pdf

The dual band ON/OFF module does not have a sensing circuit.. I got rid off all my appliance modules (now discontinued) and replaced them with the ON/OFF modules

You could also use the ON/OFF module which has a relay instead of a triac. This would guarantee you an off regardless on the attached load.

A bulb shaped icon represents an Insteon LED bulb. Try deleting the module then reinstalling it.

Try to access the ISY via this link http://isy.universal...994i/admin.jnlp If all else fails then submit a support ticket to: http://www.universal-devices.com/contact-support They'll get you up and running.

Try disabling your firewall Which browser and operating system are you using?

Can you take a look at your router configuration and get the IP address of the ISY, if so you should then be able to access using a browser. What browser and operating system are you using?

Take a look at this thread http://forum.universal-devices.com/topic/16624-isy-finder-not-found/?hl=%2Bisy+%2Bfinder

You need to clear out your Java Cache including applications, then install the current version of the Administrative Console (4.3.26) for the ISY. You should also remove power from the PLM and the ISY, then power up the PLM, wait about 15 seconds then power up the ISY. Let me know if that helps.

Which lights on the front of the ISY are either on or blinking Are you able to control any devices from the ISY You mentioned that you did an upgrade, what upgrade did you do?

Do you have a good ISY backup? Which ISY do you have What is your ISY firmware? Are you and the ISY at the same location?

Put all your lights into one scene Trigger the scene at Sunset +2 minutes eliminate the repeat and the waits and you should be good to go.....

It could be a timing issue. What type of bulbs are you using other than LED's? Can you post a copy of the program you're using to turn on the lights

What type of bulbs are you using, CFL, LED or Incandescent? Some bulbs can create noise, such as CFL's, on the powerline which could interfere with the signals reaching the other devices. You might want to also check the link tables/compare in the devices that you're having a problem with.
