# stage

An indirect measurement of power consumption by an HVAC electric heating or cooling stage.

```
let stage: Int
```

## Discussion

An integer ranging from `0` to `100` that’s proportional
to the amount of power consumed,
where `0` and `100` correspond to the min and max
power levels respectively.

- `0`: idle or off
- `100`: max.

Higher numbers mean more power.

For single stage systems, or devices which can’t provide `0-100`, `100` is acceptable as an indicator
of active power consumption

For multi stage or variable speed systems, you should map stages based on their relative power consumption
