Wear OS using Entities for Range Value Complications

I wonder if anyone has any experience with trying to get Watchmaker Studio to use a Range Value Complication to rotate a needle.

I can get any entity in HA to show as a text object but I an trying to get an entity which has a percentage to rotate a needle, operating as a gauge.

I have tried to get the TAG to accept any number of instruction combintions but so far no luck.

It maybe that the limitations of OS Wear just do not allow a value other than those baked into Watchface Studio.

Any help would be appreciated and yes I have tried Gemini and ChatGPT, which sent me round in ever decreasing circles, forgetting what it already suggested.
