Trying to customize a Dashboard template but cannot

I feel that I may be missing something very obvious....

I have a custom device with a device state called "Voltage" which is simply a numeric being constantly updated my ST_Anything device.

Im trying to display the Custom Device's Voltage in the dashboard but there doesn't appear to be a dashboard template that I can use..

Can I modify the "generic" dashboard template ? and if so, can anyone instruct me on how....

thanks in advance..

What about an attribute tile?

im going to show my "neophitism".. but unclear what that is..... will try and research....

That was it - i used the attribute template...

Thank you !!!!
