Min/Max	Instructions on how to integrate min/max sensors into Home Assistant.	Helper Sensor Utility	Calculated	0.31	internal	@gjohansson-ST	min_max	true	sensor	helper

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.

{% include integrations/config_flow.md %}

{% configuration_basic %} Name: description: The name the sensor should have. You can change it again later. Input entities: description: At least two entities to monitor. All entities must use the same unit of measurement. Type: description: The type of the sensor, this can be either "min", "max", "last", "mean", "median", "range" or "sum". Precision: description: Round the calculated mean, median or sum value to at most N decimal places. {% endconfiguration_basic %}

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 {% term "configuration.yaml" %} file:

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

{% configuration %} entity_ids: description: At least two entities to monitor. The unit of measurement of the first entry will be the one that's used. All entities must use the same unit of measurement. required: true type: [list, string] type: description: "The type of sensor: min, max, last, mean, median, range or sum." required: false default: max type: string name: description: Name of the sensor to use in the frontend. required: false type: string round_digits: description: Round mean or median value to specified number of digits. required: false type: integer default: 2 unique_id: description: Unique id to be able to configure the entity in the UI. required: false type: string {% endconfiguration %}
