Are you using a state variable or an integer variable?. A program can only be triggered by a state variable. Take a look at your variable to make sure it's properly initialized. Being that your weather data is coming from Montreal Airport is should be reliable. You might want to take a look at your error log to see is there's any HAM Weather related errors.

It's OK to plug the ISY into the UPS and the UPS should be plugged into a filterlinc. Don't use a filterlnc with the IOLincs as it will prevent their (single band) powerline signal from getting to the ISY. Try unplugging the Monster Power strip to see if it helps. Some power strips can create noise on the powerline. Is your PLM a dual band model? Changing the batteries in the MS or adding a AP shouldn't create the problem you're having. As side note you could always update your single band switches to dual band which should help improve reliability.

in addition to what oberkc suggested, have you added new electronics, appliances or CFL bulbs, etc.about the time the programs quit working

Can you post all the related programs. Where are you getting your temperature data from?

and DO NOT delete your old modem. Make sure you have a good back up.

MustangChris04, Were you able to resolve the problem? Techman

Make sure you're not exceeding the rated wattage of the devices. If you have more than one device installed in the same box then the wattage of the load must be reduced due to heat. If a device is acting up you could also try doing a factory reset on the device, then a restore device from the ISY.

Did you have a previous PLM that was working and replaced it with a new one or is this a brand new installation?

You should also make sure you have a stable power source. If your area has frequent black outs, brown outs, etc then you should first look into a whole house power line filter as power line surges can reek havoc on electronics.

The ISY log will show if a device has changed its status, it doesn't log if a program ran. The program summary shows when the program last ran and when it's scheduled to run again. If the program summary shows that the program ran then the problem is either with communications or the PLM. Being that the scenes reside in the PLM and assuming that you have no other issues controlling devices then I would focus on the PLM, power line interference around the time the program ran or if you have multiple programs running at the same time then they should be separated by 10 seconds or so to avoid collisions. Does your ISY log show any other activity about the time your program was supposed to turn off the lights?

The log would show that the program ran telling the scene to perform but there's no way to know if the scene actually triggered. Another possibility is that there's interference on the power line around the time the scene is supposed to turn off the devices. Most of the older PLMs fail around the two year mark. Sometimes they become intermittent before that completely fail. This is usually due to defective capacitors. Is the green led on the PLM lit?, if not then there's an issue with the PLM.

MustangChris04 The scenes reside in the PLM, not in the ISY. It's possible that the PLM is starting to fail. The ISY logs will not show the status of a scene, only the status of the devices in the scene. How old is the PLM, and what is its firmware version Try running a scene test for the scene that is at issue.

Assuming that you have a single band PLM and that the restore modem fails then you would most likely benefit from a new dual band modem which also has the latest firmware release.

gadgefreak, how old is your PLM. If It's more than 2 years old it's possible that it's starting to fail and needs to be replaced.

Certainly strange, probably best to go ahead and order another KPL so you'll have something to compare it with.

Try the yellow filter it will defuse the light without adding much in the way of color

The heartbeat signal is also available in the ISY log. You can also write simple program to notify you if a heartbeat signal is missed.

If the keypad button leds are too bright at the lowest setting you might want to try replacing the clear plastic lens behind the button with a yellow or blue lens take a look at this link http://www.smarthome.com/insteon-2401l-led-color-change-kit-for-keypadlinc-4-color.html

In the future you don't have to delete a device in order t rename it, just right click and rename. This will also update any programs the device is in.

With the power disconnected, try removing and replacing the memory card. If that doesn't help then I would suggest submitting a trouble ticket to UDI and let them troubleshoot it.

I would try to measure the voltage at the plug end of the power adapter to make sure you that you're actually getting power to the ISY.

Hi Gary, Take a look at this topic. I'm currently using the ISY network module to control some of the Grace tuner's basic functions. http://forum.universal-devices.com/topic/8346-upnp-help-grace-digital-media-player/ Techman

Sounds like you may have gotten a unit that someone returned. It's highly unlikely that the unit was originally shipped without the card

when you boot up the ISY what leds are lit on the front? Is the RED led on the front panel blinking?

I had also been playing with the sensor contacts. Today I'll leave it alone and just monitor the heartbeat. Seems the heartbeat only sends an "ON" signal and the state of the contacts has no bearing. I had problem with my SD card in the ISY which may have interfered with the previous heartbeats. I cleaned the contacts on the card and reinserted it. The ISY is now functioning normally. Prior to reseating the card I had trouble accessing the ISY and I had a few programs that got corrupted. In retrospect I guess we really don't need software access to the "closed" node. That node could theoretically be removed from the ISY.
