What do you use as level node in dashboard 2?

[NodyRed]

I understand there is currently no level node as in dashboard 1. What do you use as a replacement?

If you do mean this

then there's isnt any with a round shape and a wavy liquid.

Dashboard 2 gauge node gives this (waves do animate)

And you can always do it with ui_template
Examples here

Tank level indication inside of ui-template(v2)
