In case you have an appliance which produces spikey consumption (like an on/off electrical boiler) you should opt for the `left` method to get accurate readings. If `unit` is set then `unit_prefix` and `unit_time` are ignored.
In case you have an appliance which produces spikey consumption (like an on/off electrical boiler) you should opt for the `left` method to get accurate readings.
The unit of `source` together with `unit_prefix` and `unit_time` is used to generate a unit for the integral product (e.g. a source in `W` with prefix `k` and time `h` would result in `kWh`). You can override this behavior by providing a custom value for `unit`. Note that `unit_prefix` and `unit_time` are _also_ relevant to the Riemann sum calculation. Even if you provide a custom value for `unit`, ensure prefix and time accurately reflect the properties of your source data.
