Not that I could find. It was a "go in and change things" setup for me. I couldn't find much on setting up the Uni but once I figured out how it works it's a powerful little device for the price.
I seem to remember going into Peripherals menu option on the Uni and adding the Voltage option from there.
I did add the peripheral option in the UNI web interface.
My issue is getting HE to communicate with it,
IP was set too in HE, unless there is multiple settings that need IP?
Which driver are you using?
ADC child and Shelly UNI
That doesn't sound like the driver I'm using so, unfortunately, I can't help.
Some Shelly Uni Plus drivers aren't doing voltage. The bundle install made by @dimitry.rozovik does
I provided a link to this driver above. That's the driver I'm using. It's dead simple to setup.
So I probably should delete both and re install the driver you suggested, so I keep it straight.
Will do that later this afternoon.
Thanks
Cleared everything out and reloaded only that zip bundle you suggested.
What do I choose when creating virtual device?
Shelly Plus/Pro xPM
or
Generic component input event
Or
?????
--Select "Shelly Plus/Pro xPM" as the device handler.
--Go to the shelly itself (shelly IP) and add the peripheral "Voltage" device.
--Then open Hubitat Shelly device put in the Shelly Pro Plus IP address. Save.
--When the driver shows it online on HE then hit configure and the child devices will show up.
Edit, I had the Uni plus incorrectly configured.
Thanks Everyone!
Finding the voltage is off by -0.24 volts compared to 2 voltmeters.
Any way to adjust?
Is the .24 volts the same across the entire range?
Had to grab a shop power supply as the power to unit was my test power too.
Yes the voltage difference is there at a lower voltage too. At 7 volts it off by .17
Let me look at something. I think you might be able to massage the voltage. Mine was spot on so I didn't have to. It will be a bit as the vehicle with the Uni isn't here right now
If not you could easily do it within a rule in RM
Amazon screwed up the order so bad I got another one to try 
Just need to go get it from Amazon Locker today.
The original lost in the mail showed up as an honest neighbor redelivered for the lame USPS
This may be it, some testing to do here
Edit: Appears to do the trick 
Not sure if that is correct for my data input, but it's working
Can I make a suggestion. I'm assuming the .24 was at 12V and you said the .17 was at 7V.
If that's the case, then you are off by about 2%. You could use X + (X * .02) and I think that would get you closer through the entire range. If that is important to you.
You could play with the .02 to try and get even closer if you wanted
The second UNI I received was closer on the voltage with a 0.81 % calibrator
X + (X * .0081)
Guess I will use that one....
This project is done and I learned more than I knew before.
Thanks to Everyone here....
Glad I went with HE C8-Pro
