UPB intergration stimied

UPB intergration is the goal …This is what I am trying to follow Universal Powerline Bus (UPB) - Home Assistant
Also trying to follow this guys experience

Hi all, first post here. I just got the HA-Green and I have quite a bit of UPB. I used the Simply Automated UPB-PIM USB device and plugged it into the bottom USB port on the back of the HA Green unit.
I then uploaded the export from UPStart to the same directory as configuration.yaml
I set up the integration as follows:
Serial: /dev/ttyUSB0
File location: xxxxxx_2024JAN1.upe
Clicked on Finish and then was presented with all of my UPB devices. Assigned them to rooms and then created some test buttons on a test dashboard. All seems to work just fine."

So I have put the UPB .upe file into the Samba Z folder and have connected the PIM to the HA Green USB port but am stimied at this point. Of course I have Chase Home Lighting Latest.upe file

Cannot find a PIM address to use here http://homeassistant.local:8123/config/integrations/dashboard
You all are really appreciated for staying with my awkwardness. Thank YOU… Steve

I may have put the .upe file in the wrong place? Where is the directory “configuration.yaml”

I did it guys… HOORAY!!! I finally read the instructions Configuration.yaml - Home Assistant which I am sure you would have told me to do…

I now have the basic UPB integration with 70 devices showing…Thank you BoboSD for spelling our what you did…The UPB integration instructions needs some clarification in the prerequisite area…

Now I am less inclined to sack my HA Green… However I am still thinking like the fellow who wrote this “WTH Do I still need to be a rocket scientist to get things done in HA”
