I have been connecting to my ISY994i using start.jnlp (IoX finder) or IoX launcher. I just had to replace my router, and the ISY994i's connection to the Ethernet network and power and the Insteon PLM was interrupted during the replacement. I reconnected the ISY994i to the PLM and the PLM is connected to house power. The ISY is connected to the FiOS extender (Had to replace the router next to the ISY994i in my upstairs office with a FiOS extender as the actual router had to go in the basement next to the system unit.) So the connections seem right. I logged into the router and found the URL of the ISY994i is now 192.168.1.159. So I click on start.jnlp to start the IoX finder. It doesn't see my ISY994i. I clicked Add, and in the dialog box that says Enter the URL I typed 192.168.1.159 and pressed OK. "Invalid URL." I seem to remember that when I was connecting to my ISY994i before, there was something after the "192.168.1.159" that was needed to connect. Is that my problem? I need to know what else goes into the URL?

Thanks for any help.

Comparing it to mine yours should be https://192.168.1.159:8443/desc

I know at one time with the 944 it used to use 8080 instead of the 8443

@KConoverSince you're using an ISY994i try http://IP.ADDR.OF.ISY/desc

The instructions by @tazman are for a Polisy.  Note in the case of Polisy I would use: http://IP.ADDR.OF.ISY:8080/desc rather than https://IP.ADDR.OF.ISY:8443/desc    (in short http and port 8080 go together, and https:// and port 8443 go together-- and since your home network should be trustworthy there's really no need for the extra overhead added by using https:// and 8443)

Note:  IP.ADDR.OF.ISY must be replaced by an actual IP of the ISY, so in your case http://192.168.1.159/desc

Thanks for straightening it out for me!

Thanks, tazman and MrBill!  I gave myself a >dopeslap to the head< and realized that I hadn't added the http:// at the beginning. http://192.168.1.159 did the trick; the IoX Finder added the /desc at the end for me. I did have to reboot the ISY, but now everything seems to be working fine.

I am also relieved that I can now get Insteon wall switches again; one of mine just died. I was thinking about upgrading to an EISY so I could add Z-wave stuff, but I like the instant-ish response of Insteon switches and lamp modules, and I hear that Z-wave is not as fast as Insteon. Now if I could only figure out what Matter is going to do to people like us and companies like Insteon and Universal Devices…

Thanks again!
