Min/Max

The Min/Max integration consumes the state from other sensors to determine the minimum, maximum, latest (last), mean, median, range and sum of the collected states.

The sensor provided by this integration will always show you the lowest/highest/latest value which was received from all monitored sensors. If you have spikes in your values, it’s recommended to filter/equalize your values with a statistics sensor first.

If the source sensor provides an unknown state, it will be ignored in the calculation except for sum where it will set the state to unknown. If the unit of measurement of the sensors differs, the Min/Max sensor will go to an error state where the value is UNKNOWN and unit of measurement is ERR.

  • 从列表中选择 Min/Max。

  • 按照屏幕上的说明完成设置。

Name

The name the sensor should have. You can change it again later.

Input entities

At least two entities to monitor. All entities must use the same unit of measurement.

Type

The type of the sensor, this can be either “min”, “max”, “last”, “mean”, “median”, “range” or “sum”.

Precision

Round the calculated mean, median or sum value to at most N decimal places.

YAML configuration

Alternatively, this integration can be configured and set up manually via YAML instead. To enable the Integration sensor in your installation, add the following to your configuration.yamlconfiguration.yaml 文件是 Home Assistant 的主要配置文件。它列出了要加载的集成及其特定配置。在某些情况下，需要直接在 configuration.yaml 文件中手动编辑配置。大多数集成可以在 UI 中配置。 [Learn more] file:

# Example configuration.yaml entry
sensor:
  - platform: min_max
    entity_ids:
      - sensor.kitchen_temperature
      - sensor.living_room_temperature
      - sensor.office_temperature
