Yes, you can manually delete everything in the temp folder, first close all open programs then delete the folder contents. To make it easier, I put a shortcut to my temp folder on my desktop

If you have a firewall program such as Norton, it periodically deletes all the files in the Windows temp folder. The next time you access the eisy via the Admin console the "state" files are recreated, which could be why you're up and running again

@TriLife In Windows 11 search for a folder called "temp" In that folded you'll find the files that @Geddy mentioned (see attached screenshot) They're all temporary files and can be safety deleted

@TriLife I'm running Windows 11 with all the latest windows and java updates and the admin console works without any issues. Take a look at these two links https://wiki.universal-devices.com/index.php?title=Main_Page#ISY_Finder_does_not_find_ISY https://wiki.universal-devices.com/index.php?itle=Main_Page#Java_applications_are_blocked_by_your_security_settings

You may have a bad connection on the hot lead of the KPL You can also try doing a factory reset on the 2486 by pulling out the set button, then pushing it in and holding it in, the KPL will beep, continue to hold the set button in until the beeping stops. If the reset was successful the load on the KPL will turn on

@jukeman A restore device writes the link tables to the device not the PLM A restore PLM writes all the link tables stored in the EISY to the PLM (not to the devices). You can verify/compare the link tables in a device by clicking on TOOLS | DIAGNOSTICS | SHOW DEVICES LINKS TABLE. After the table populates click on "compare" which will compare the links stored in a device with the links store in the EISY. If you have a mismatch then do a restore device.

If it worked after a restore device then it means that the link tables in the device were incorrect. A restore device writes the link tables that are stored in the eisy back to the device. When you added the device you may have had a communication issue, i.e. noise on the powerline or poor communications between the PLM and the device that corrupted the device link tables.

@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
