I'm trying to set the maximum for a dashboard gauge as an already existing entity. However I can only input a numerical value. How do I set the maximum as an entity?

With difficulty is the simple answer
You might be able to manage it with this HACS card: https://github.com/gadgetchnnel/lovelace-card-templater which can wrap most cards and let you pass a template to most options

Is any yaml code needed? If so can you give me the code please?

@signal aurora do you have the yaml code?

I haven't really used it, but I think it's something like:

type: 'custom:card-templater'
card:
  type: gauge
  entity: whatever
  max_template: '{{ states("whatever max") | float}}'```
