The firmware versions you're showing are not the latest versions, once you get the access issue cleared up you should update your packages again as it's possible your update didn't complete.
Are you on a Mac or a PC?
If you're using a VPN disable it.
Clear your Java cache again, be sure to check all 3 boxes, then download the IoX Launcher from here:
https://isy.universal-devices.com/start.jnlp
Also remove power from the eisy for 30 seconds and then allow it to reboot
 
 
 
 
 
 
 
 

Try rebooting your computer, then clear your java cache amd download the launcher again

If that doesn't work then it's possible your firewall is blocking  the launcher application. Take a look at these two links.

You really only need the two nodes, open and heartbeat. If the sensor isn't open then it's closed. However,  in the eisy if you look at the options for the open close sensor you'll see the option for the close node (2 nodes).
It's also possible that insteon, in the current sensor firmware, eliminated the close node.

Factory reset PLM
Remove PLM from power, hold down the set button and continue to hold down the set button after plugging in, the PLM will beep, hold the set button in until the beeping stops
-------------------------
Factory Reset EISY
Click the button ten (10) times
Please wait 5-10 minutes after factory reset before attempting to reconnect to system. If System is not found by IoX Launcher after the wait period please reboot system by clicking the button five (5) times and waiting two minutes for system to come online.
Note: after a factory reset the user name and password reverts to admin/admin
After you reset the EISY log in from the admin console and run update packages, don't touch anything until the update completes and you see a notice to reboot.
 

@johnjces
If the keypad itself is located in a subfolder in your device tree you'll need to move it out of the subfolder. No need to touch any of your scenes. 
Sounds like the triac in the KPL got fried. Be sure to fix the light socket before you replace the KPL. After the replacement do a EISY backup

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

Did you clear your java cache, checking all 3  boxes, before downloading the IoX Launcher from here:

Why not use one Zwave network and add two 800 series range extenders/amplifiers, one in the garage and one in the house.

Why not just use a Zwave 800 amplifier/repeater. Placing the Zmatter dongle outside of the house, and exposing it to weather,  is probably not a good idea

Try replacing the ethernet cable between the router and the eisy. Also try removing power from the eisy for about 15 seconds. 

Either your Polisy bios needs updating or you have a signature failure. You'll need to contact support. Here's the link to submit a support request:

Exactly follow the attached procedure to replace your PLM.  
It's best to do a factory reset on your new PLM before installng it. When you install the new PLM the deleted addresses in your previous PLM will be removed. 
Replace PLM Procedure (EISY or POLISY).pdf

Being that you're using a new/different PLM on your EISY you need to exactly follow the replace PLM guidelines for your EISY. See attached
The reason nothing is working is because your EISY is currently programmed with the serial PLM and doesn't yet reconize the USB PLM
 
Replace PLM Procedure (EISY or POLISY).pdf

I have the ZAC38.  The admin console will display the AC Mains Disconnected assuming that the eisy/poolisy is on a UPS.
The only glitch is when the controler is rebooted, the AC Mains stats doesn't update to show connected, however if A/C power to the ZAC38 is lost then the disconnect will again show in the admin console. After a reboot, if you unplug then reconnect the ZAC38 the admin console will show the correct status.
If your controller and router are on a UPS then you're able to receive a power fail email
 

@smorgasbord
Attached is an updated set of instructions for replacing the PLM on an EISY/POLISY
Personally, I prefer the USB PLM as there's one less thing to fail.  It's also easier to locate the PLM away from the controller using a USB cable. 
Replace PLM Procedure (EISY or POLISY).pdf

Other forum member(s) have installed the ZSE70 in the eisy without issues. 

@smorgasbord
Try using Multimedia Messaging Service, which AT&T still supports. 
  (your phonr number) @MMS.ATT.NET

Try removing power from the controller for a few minutes. If that doesn't resolve your issue then post a copy of your error log

The ISY backup is located on the harddrive of your computer.  It's named IoX-Backup.v(your firmware version #)_(date of backup)
Your existing ISY firmware is OK for the migration.
If you're using the same PLM you had on the ISY, then power down both systems, Remove the PLM from the ISY and connect it to the eisy, then power up the eisy.
On the eisy, under FILE, select restore IoX. Select the ISY Backup file you just created
 
 
 

@gempro
The link tables for a scene are contained in the devices themselves, so if you disconnect the PLM the scenes should still work, i.e. if you have 3 devices in a scene and turn on one of the devices the other devices should respond.
Not knowing how you first installed the PLM it's probably best to do a factory reset on your PLM and then follow the written instructions for replacing a PLM. See attached file.
Replace PLM.pdf

170001 are informational, not errors, you can ignore them. you most likely have a device, program or node server that's very active.

The complete migration instructions can be found at this link:
https://wiki.universal-devices.com/Eisy:User_Guide#Migration
Be sure to follow the migration guide exactly.
 

In the PG3x configuration for Weatherflow you should set the forcast option to 0. You may have to delete and reinstall the node server for that to take effect
 
.

It appears that you have a communications problem between the PLM and your devices.  It's possible that the you could have interference on the powerline. Have you recently added any new appliances or other electricial devices?
Take a look at this wiki article:
INSTEON: Troubleshooting Communications Errors - Universal Devices, Inc. Wiki (universal-devices.com)

When you add a Zwave device to the eisy you'll most likely end up with extra nodes that you don't need. The reason being is that, unlike Insteon,  zwave devices are designed to work with various Zwave hubs, and each hub may require and/or support these extra nodes.
What most of us do is create a folder and move the nodes we don't use into that folder which will give you a cleaner device tree.
I've attached 2 files that may help explain associations. Being that the eisy already supports scenes you most likely won't need the associations or scenes nodes that the device installs
