Wouldn't a simple program work just as well? If FAN is switched on THEN Wait 20 minutes Set Fan OFF ELSE

Put your zwave devices, one at a time, into the linking mode then on the admin console zwave menu click on Remove a Zwave device. After it's removed you can then add it back. Another possible option, being that the devices are technically still installed is to use Repair Links in your Zwave menu which should add it back to your device tree. Attached is the Zwave user guide which should answer all your questions. ISY Zwave manual.pdf

If you've removed your wave devices then there is nothing more you can delete. I'm assuming that you removed then via the Zwave menu and not just deleted them from your device tree. If you're planning on using Zwave then you should really update your Zwave dongle to the new 500 series dongle which can be purchased from UDI. UDI no longer supports the 300 series board which means that you won't be able to update your ISY firmware to the current version 5.3.4 which is now Zwave certified.

If you're still having issues you may want to update your ISY to the latest firmware 5.3.4 and then clear your Java cache and applications and download the ISY finder again. The update from 5.2.0 to 5.3.4 is painless.

When you open the ISY launcher what firmware version displays for the ISY?

This Is this the link you should use after you deleted your java files and applications. What version of the ISY firmware are you running? https://isy.universal-devices.com/start.jnlp

You can only have one device in the linking mode at any one time. Make sure all devices are not in the linking mode then try to link one device.

Take a look at this How to set JAVA_HOME in Windows 10 | Java Tutorial Network

It's possible that Java didn't get installed in the default folder. If that's the case, uninstall and reinstall it. The default location for Windows 10 is :C:\:ProgramData\Microsoft\Windows\Start Menu\Programs\Java

What device can't the ISY communicate with? In the admin console under files, turn off the write updates to battery devices and see if the error message goes away. Do you have any red exclamation points showing on your device tree?

Trying clearing your java cache including all applications which will delete the finder from your desktop then download the ISY finder again. Reboot your computer before you download the finder,

try disabling the switch by pulling out the set button then. take a look at any programs that include the switch as they may have been modified when you upgraded your firmware causing the program to enter a loop. Also make sure that your firmware and UI are the same version.

Make sure your ISY firmware and UI are the same version If not, clear your Java cache, including all applications, down load the correct UI version for your ISY firmware

If you run the topography report you can then sort its address column making it easy to find the problem device. Especially helpful if you have a lot of devices.

Do a backup of your ISY so you'll have the correct link tables in the event you have to do a restore

Javi and jwagner010 Just tried the Fade/Stop with the ZRTSI and the shade stops at the MY position. Many thanks for the input

I use variables to let my programs know if the shades are open or closed. If one were to use fade stop does the somfy motor status in the ISY show as open or closed?

Were you using the ZRTSI or the URTSI? The ZRTSI communication with the Somfy motors is not bi-directional so the ISY and ZRTSI have no way of knowing the status or position of the shades.

If you turn on any of the other affected switches do all the lights turn on or is it only when you turn on the den switch. If it's only the den switch then I would factory reset that switch and see if that corrects the problem. Also reboot the ISY

I'm using the ZRTSI so the 50% option isn't an option as the ZRTSI won't recognize it.

How are you interfacing the URTSI II with the ISY as it only has inputs for RS232 and IR.

Your devices somehow became crosslinked. This can happen if several devices are in the linking mode at the same time.

The ZRTSI is a Zwave to RTS bridge. Being that the only way to control the shades from the ISY is Zwave using the ZRTSI a scene won't make a difference as the only two node options are on or off. It's possible that the Polisy with Wi-Fi may be a work around as the Somfy Mylink is a Wi-Fi to RTS bridge.

Another option is to run the Topology report. Tools | Generate Topology. The report will give you a list of all your devices along with their address and info on all your scenes. You're able to sort the columns in the report which can be quite helpful.
