Gauge math and warnings

Gauge math acts only on the source data.
RPM 0-4500. Normally from 600 to 3000. Warning from 3000 to 4500.
The output of four characters is inconvenient. Gauge math applied v/1000.

Warning does not work.
A warning is triggered on the final data, not on the source. And the final data does not match the settings due to Gauge math

I’m not sure what you mean, but applying warning level on RPM is best achieved with gauge levels instead of gauge math. Gauge math is only applied to display value of that specific gauge and has no meaning to actual input values or other gauges. That is how it is supposed to work.

readings on the left, the same parameter as on the right, but divided by 1000.
The warning does not work. It is configured
by a value greater than 3000.
After dividing by 1000, the value cannot be greater than 4.5
How to set up a warning greater than 3000, if the value does not exceed 4.5 after calculations?

Set the warning to 3.0))):grin::grin::grin:
Or create a second sensor on with values ​​in thousands

But not obvious.

RPM 0-5
