Try clearing your java cache, be sure to check all 3 boxes, then download the latest version of the IoX Launcher from here: https://isy.universal-devices.com/start.jnlp

The Zwave device has an option (a button press) to put it into the linking mode, it would be the same function as when you added to your controller. What's the make and model of the device you're having an issue with?

UDI free support has ended however you can still get support from UDI for the ISY, but there's a fee. Maybe it's time to bite the bullet and upgrade to the EISY.

If you're referring to the individual devices in a scene, use the Insteon option.

Try putting one of the devices in the linking mode, then do a device query. The status window in the Polisy will be blank until that node sends a report.

@tas99 Take a look at this thread: https://forum.universal-devices.com/topic/42117-cant-launch-the-admin-console/

@GSutherland It's probably best to contact the developer @xKing

Unfortunately, I've run out of viable ideas. The only other suggestion, assuming you have a current and good ISY backup, would be to factory reset the ISY then restore the backup. If you don't have Zwave and battery-operated devices, the restore should go smoothly. It's also possible the SD card failed or the network connection has issues as it appears that your ISY to router connection may not be bi-directional.

Based on everything covered above, it seems the problem is between the ISY and your router. Verify that the ISY IP address and the MAC showing in your router are the same as those showing in the IoX Launcher.

@tas99 Are your computers and ISY on the same network. i.e. not on your guest network. Are you able to see the ISY in the list of installed devices on your router? Is the ISY connected directly to the router?

@tas99 Take a look at these threads. There has been issues with Windows 11 and the admin console Can't install Admin Console on Windows 11 - IoX Support - Universal Devices Forum (universal-devices.com) New Windows 11 computer, unable to connect to ISY 994 - ISY994 - Universal Devices Forum (universal-devices.com) Admin Console not Responding - PC version - IoX Support - Universal Devices Forum (universal-devices.com)

Have you tried rebooting your router, and /or disabling your firewall. What type of computer are you using? Also try removing power from the ISY

Here's where you insert the runtime parameters. Take a look at the installed devices and see if your ISY is listed. Did you previously reserve an address in your router for your ISY? Make sure DHCP is enabled in your router

Attach the Zigbee antenna, as the RF from the unconnected port could be causing a problem. If the Zwave antenna is located close to a copper pipe or metal duct it could interfere with the Zwave RF signal. Try relocating the Zmatter enclosure using a USB extension cable.

Clear your java cache, including checking the box "installed applications" then download the (revised) IoX Launcher from here: https://isy.universal-devices.com/start.jnlp

Yes, the cable that came with the PLM is ethernet to DB9 which is used with the Polisy not the ISY.

@tas99 Another thing you can try is installing a new Insteon device if you have one laying around. If you don't have a spare then delete a device that's installed, factory reset it, then try to install it. This process will eliminate some of the possibilities.

Ether the PLM is defective or The ISY link tables are defective or The cable between the PLM and the ISY is defective or The SD card is defective or failing If you have another ISY to PLM cable, the one that shipped with the serial PLM, try swapping it out. You can also try removing power from the ISY, then remove the SD card and clean its contacts with a soft eraser and reinsert it.

Your PLM Links table looks on the lite side. It's also missing the A2 links. You should have more than 21 links unless you only have a small number of Insteon devices. Try doing a restore PLM, then another PLM link count.

What's your ISY firmware and UI version? Some things to try: If you click on TOOLS | DIAGNOSTICS | PLM INFO / STATUS what does it show? Click on TOOLS | DIAGNOSTICS | SHOW PLM LINKS TABLE. What is the links count?

@tas99 Have you added any new electronics or electrical devices in the last few weeks? Being that the problem recently cropped up and is intermittent, there's a good possibility that you have noise on your powerline. How many dual band insteon devices do you have in your system, and about how old are they? Are both legs of your powerline bridged using dual band devices? On rare occasions, a defective insteon device can create noise on the powerline.

If the problem is only happening with one specific device, then factory reset the device and then do a restore device. If the problem is with numerous devices then the PLM is having difficulty communicating with the devices. Take a look at the link below for troubleshooting. INSTEON: Troubleshooting Communications Errors - Universal Devices, Inc. Wiki (universal-devices.com)

The green arrow means that there are pending writes to that device. Right click on the device, then click on write updates.

You could do it with a program IF Motion sensor is switched on THEN Turn on light Wait xx minutes Turn off light ELSE

What was your previous firmware version? Have you tried accessing the ISY via the admin console? Important User/Password changes for 5.3.4: If your current version is 5.0.7 or earlier, then after installing 5.0.8 or later your userid and password will be reset back to the system default. The system default is admin / admin
