The features of the Super Tile Gauges are noted in the linked thread. There are color segments, but not gradients. The thickness of the Radial style is thinner which might fit your needs – there’s not a manual override of the arc thickness.
The Custom Tile gauges in this thread are open source, so you can tweak them to your needs. I would also strongly recommend reading the documentation for the underlying Gauge Library used for each Custom Tile as noted in the original post.
For example, from the Gauge.js documentation it looks like passing in a limitMax: true in your Advanced Chart Customizations (JSON) might cover what you need as it seems to prevent the ‘max’ value of the gauge from increasing. From a quick test, if you are over the ‘max’ with that setting, the pointer is just pinned hard-right to the max but it doesn’t increase the ‘scale’ of the gauge range so you don’t have to worry about the reset effect.
