@smarthome_newbie Before try the steps below, did you clear your java cache , checking all 3 boxes, then then download a new IoX Launcher? ---------------- If you have a later model ISY994 the SD card can be removed from the front without opening the case. Remove power from the ISY then push in on the SD card and it will pop out. Clean the contacts on the card with a soft eraser and then reinsert it. Take a look at this link: https://wiki.universal-devices.com/ISY-99i/ISY-26_INSTEON:Replacing/Formatting_an_SD_Card

@smarthome_newbie In addition to what @paulbates is suggesting....... Did you download the launcher from here: https://isy.universal-devices.com/start.jnlp Also take a look at this link Upgraded to Mac OS15.2. Lost ability to open AC....FIXED - eisy - Universal Devices Forum

@Javi Under advanced status configuration, when I select equal to AC MAINS DISCONNECTED as a value and select save the value defaults to 2NULL

@noobmuch Do you have an active UD portal account? Are you trying access the ISY via LAN or Remote using UD Mobile?

@Turtle Any plug-in dual band module will act as an access point, i.e. LampLinc or On/Off Module. The advantage is that you get both an access point and a module that will also control a load.

If your previous switch was powerline only that would explain the marginal communications. The newer swirches have improved hardware and updated firmware.

The imports from Asia to North America have slowed to a crawl. It's out of UDI's control.

@armymutt After you clear your java cache, be sure to check all 3 boxes, then download the IoX Launcher from here: https://isy.universal-devices.com/start.jnlp This will place a new launcher icon on your desktop

@diggler Take a look at these troubleshooting links: Can't Determine INSTEON engine INSTEON: Troubleshooting Communications Errors - Universal Devices, Inc. Wiki

@GaryK4 It sounds like the two legs of your powerline may not be properly bridged. Take a look at this article. INSTEON: Troubleshooting Communications Errors - Universal Devices, Inc. Wiki

Select HTML instead of TEXT for the message format, then the line feeds will work.

To get a line feed in the email add "<BR>" at the end of th line. I'm not aware of a variable that reflects the status of a program. You could use the status of a device in a program.

@matthewjocko After the update did you clear your java cache and download a new IoX Launcher? What was your firmware version prior to updating?

Try rebooting the ISY again Does your ISY show the PLM as connected? (Tools | Diagnostics | PLM info/status) Under Tools | Diagnostics | Show PLM Links Table, what is your PLM link count? Try doing a restore device on one of your switches. It will write the link tables stored on your SD card to the switch. A restore device does not change anything on the SD card.

@pooderbill All your programs, device info and ISY firmware are stored on the removable SD card in your ISY. After you've cleared your java cache, download the IoX launcher from here, which will place a new launcher icon on your desktop: https://isy.universal-devices.com/start.jnlp Once you get everything working be sure to make an ISY backup. Also verify that you have the PLM plugged into port A in your ISY.

To add what @Guy Lavoie suggested, when factory resetting the switch you need to keep the button pressed until the beeping stops. If the reset was successful the load will turn on. I doubt that the switch is defective. It sounds more like a communication issue between the PLM and the switch

Attached is the manual for the 2486D. Factory reset instructions are on page 16 and 17 The 1011 means that the PLM is not communicating with the device and that there are pending links to be written to the device. 2486D 8 button dimmer manual.pdf

Your port should be 587, and TLS should be checked

You don't have to put it into the linking mode for a restore device If you've recently added new electricial devices to your home they could be the source of the noise. If after you've tried all of the above and you're still having issues let me know and I'll send you more troubleshooting suggestions

Right click on the Keypad in your device tree then click on restore device If that doesn't resolve the issue then you can try doing a factory reset on the Keypad followed by a restore device. If the these two options don't work then it's possible you have poor communications between the ISY and the Keypad, possibly due to noise on your powerline.

It sounds like some of your link tables didn't get written to the new PLM. Did you exactly follow the attached replace PLM procedure? After you get everything working be sure to do a backup. Replace PLM Procedure (EISY or POLISY).pdf

When you run the "start.jnlp" program it will install the IoX Launcher icon on your desktop. If you still don't have the icon then clear your java cache again and run the the start.jnlp program again.

@toptierweb Did you clear your java cache, checking all 3 boxes, before downloading the IoX Launcher from here: https://isy.universal-devices.com/start.jnlp

I installed the latest version, Version 8 Update 451 (build 1.8.0_451-b10).

I had the same issue with the current Java update. I had to uninstall Java and re-install, that resolved the problem..
