Did you look on insteon's website? They have them

I dont believe Matter support has been officially released with the EISY yet.

No there is not. It automatically goes to the next number. 

Thats not what Im asking. If you click on the controller of your scene in the admin console (each keypad which should be RED), did you configure what your switches are supposed to do there also?

Did you follow the migration procedure or simply did a restore?
 

You need to use the hue nodeserver or network resources to connect your eisy to your hue hub 

There is a full thread on this issue:

factory reset the device then try again. Make sure that your UI matches the firmware.
If you're manually putting in the device address, make sure that its the right one. Sometimes, people mistake a B for an 8 or D

Eisy can talk to Home assistant which may have the ability to work with those devices.

No it does not. This connects directly to your LG TV for tv control functions. It does not connect to LG services

Range varies due to environment. Being that this is their beta release, it'll be impossible for anyone here to say what range you would get based on their experiences. 
I suspect either you are too far or your device is not supported. Does it show up on the list on the firmware update page?
 

Im assuming that you upgraded your polisy to the latest firmware. In the firmware notes section, it shows current device compatibility list. That device is not on there.

I'm assuming you updated your system to the latest firmware. According to the firmware update release notes, motion sensors are not supported yet

Not possible. You'll have to set a reservation in your router

Should've received an email in addition to logging into the store using the email associated with your account (portal address)

The eisy is brand new- you'll get the latest model regardless of when you order it. At most you'll have to update the firmware which youd have to do anyway due to when firmwares can be pushed out and you receiving your product...no different than most consumer electronics nowadays. 
You can wait but then you run into the possibility of UDI being out of stock when you're ready. 
No one can really say what you will experience.  There are many here that hasn't had issues and others who have. I'd peruse the eisy channel to see others experiences and decide whether or not you're ready to chance things. That way you can make an informed decision.  Personally, I think you will be ok but with everyone's system being unique, only you can decide that. 
There are a few posts on here with others using long cables without issue. 

If you upgraded from 4.xx to the latest firmware, the instructions on the firmware page states that the password was reset to default

Your best source of information would be through the manufacturer of the product. I'd use the support link on the page that you linked to.

It already does support hue. You can use the hue node server via Polisy or eisy or network resources. 
If you Google isy hue, you'll see plenty of posts on the matter. Or you can just scroll down on the forum until you see the Node Server

Id clear java cache to make sure your UI and firmware matches. Once done, click on a line, choose update, and then save each program again

You don't need it. Some like myself have 2 systems. 1 to run our home and the other for testing. 

Due to the mixed nature of scenes in the 5.x.x firmware, that is no longer available
