Operators & thresholds

A rule compares a device tag against a threshold using one operator:

Operator Fires when value is…
gt greater than the threshold
lt less than the threshold
gte greater than or equal
lte less than or equal
eq equal to the threshold

Scope: a rule targets a specific device, or all devices (leave the device unset) to apply the same condition fleet-wide on a shared tag name. Set thresholds in the tag's engineering units — apply scaling on the tag so raw values and thresholds line up.
