Gauge mode is not accurately reflecting the value provided.

[Goobaroo]

I'm using the gauge mode on the custom:cb-lcars-multimeter-card, however I can't seem to get the bar to align with the current value.

The current temperature is 19.1°C but the graphic is showing maybe 10° less.

Is there something obvious that I'm missing to get this working as expected?

I think it is related to the _min value, starting the gauge at 0 it looks correct.

This is not expected, but I also cannot recreate it. Using a test input_number helper, I am seeing the bar draw where it should be. Ignore the unit I didn't set it, otherwise the code is the same as yours (just hid label so we can see the state value for comparison)

Two things - can you post your entity's attributes/state from developer tools? Also, try to do a Empty cache and hard reload (open browser's dev tools, then long press the refresh button and it is the 3rd option in chromium-based browsers)

Tried clearing the browser. I tried a few different browsers, and in the HA iOS app still displays incorrectly.

Changing the source value to an input_number it does render correctly. Maybe related to disabling slider mode?

Perfect thanks for narrowing it down.. I'll take a look at this (there is indeed a bug with this calculation)
