Posted July 3Jul 3 Suddenly, my EISY will not do anything. No light on my PLM so I am installing a new PLM. I turned off the EISY I removed the old PLM Plugged in the new PLM and hooked up the cable to the EISY. Now, when I launch the IoX Launcher, it cannot find my EISY (see image attached). Tried holding the "set" button on my new PLM - no difference.
July 3Jul 3 I'd try un-plugging power to the eisy, wait 10 seconds, and replug, retry Edited July 3Jul 3 by paulbates
July 4Jul 4 Verify the easy IP address with your router. Then click on the add button in the Launcher and add the IP address manually.
July 4Jul 4 @JoelW Be sure to follow the replace PLM procedure. See attached Replace PLM Procedure (EISY or POLISY).pdf
July 7Jul 7 Author Okay, thanks for all the help. Unfortunately, I am slow to follow up because I have had no power and no Internet until early this morning. Anyway, I already carefully followed the procedure and still cannot find anything. On 7/4/2025 at 7:00 AM, DennisC said: Verify the easy IP address with your router.

I even tried all the unlabeled devices and none of them are hard wired like the EISY. Frustrating!!!!
July 7Jul 7 @JoelW Do you have DHCP enabled on your router? Also check and/or replace the ethernet cable between the eisy and the router. Where your ethernet cable is plugged into the eisy, Is the orange led lit, and is the green led blinking?
July 7Jul 7 Are you on a PC or MAC and what version is it running I would focus on your Router. Verify that DHCP is enabled on the router, then reboot your router. Also try clearing your java cache, be sure to check all 3 boxes, then download the IoX Launcher from here: https://isy.universal-devices.com/start.jnlp If you're then still having issues try turning off your firewall.
July 7Jul 7 Author I am on a PC running Win 11 Router has DHCP running and all my other dhcp devices are working fine. Cleaned the Java cache as suggested with all 3 boxes. Followed your link to install Start.jnlp. It updated my Java version and installed a new start.jnlp. Now, when I launch the new start.jnlp, I get "IOX Finder: Not Found
July 7Jul 7 Author FYI, Before the PLM died (I am assuming that is what happened) everything was working perfectly.
July 7Jul 7 The issue you're having is totally unrelated to a failed PLM If you have a VPN turn it off, also turn off your firewall Remove power from the isy for about 30 seconds, then boot it up Edited July 7Jul 7 by Techman
July 7Jul 7 Author Okay, I think we need to address this one step at a time. I repeated all the steps again, and I still see no device called EISY (or eisy) in the list of devices on the router. If I do this with any other device, it goes to offline status and then returns to online status when it is turned on again. I do have an offline entry for polisy: Not sure what to do!
July 7Jul 7 Did you reboot your computer? Did you reboot your router? Remove power from the eisy for 30 seconds, then boot it up
July 7Jul 7 @joew One other thing you can try - Click on this link: Home - Universal Devices - The Most Powerful Automation, Energy Management, and IoT Platform In the upper right corner, click on My ISY, then click on "keep" and "open"

So here I am, stuck in never never land. 13 hours ago, Techman said: @joew One other thing you can try - Click on this link: Home - Universal Devices - The Most Powerful Automation, Energy Management, and IoT Platform In the upper right corner, click on My ISY, then click on "keep" and "open" When I click on My ISY it links to a download for start.jnlp. So here I am, stuck in never never land. Is there any way to determine if the EISY device is the problem?

July 14Jul 14 Hi, kinda in the same boat. All of a sudden none of the programs and timers were working. My Eisy looked like it had power and the PLM green light on. Was working fine for months and then suddenly nothing. Could not see the Eisy IP on my router dashboard and would not respond to a ping. Changed out the network cable, tried different port on the switch, unplugged the Eisy -- still nothing. Running IoX was useless with it always not finding it- No ISy found. If I took the Eisy and plugged into a monitor and keyboard, I could see at least something was working on the screen. tried to ping my computer from the Eisy but got "no route to host" message. It's like the network portion is down. Any suggestions?
July 14Jul 14 Author Open a ticket with UDI. I just mailed my EISY to them for testing and repair or replacement.
