Daily Sensor custom component for Home Assistant. It takes aggregates an input sensor until midnight. Then it resets. Aggregation is configurable - available options are: minimum, maximum, sum, average (mean), median, standard deviation and variation.

Install the custom component (preferably using HACS) and then use the Configuration --> Integrations pane to search for 'Daily Sensor'. You will need to specify the following:

• Name of the daily sensor. This name needs to be unique in your Home Assistant installation.
• Name of the input sensor - this is the sensor that the daily sensor will aggregate during the day.
• The aggregation to run on the input sensor - you can choose min, max, sum, mean, median, stdev and variation.
• The interval in seconds in which to update this sensor.
• Automatic reset at midnight ? By default selected, but can be deselected to allow manual reset

That's all. You can add the component multiple times to aggregate other sensors. All sensors will be reset at 00:00 local time and can be reset manually by calling the reset service for each instance of the component.

This component is most frequently used to create a minimum and maximum daily temperature sensor based on a temperature sensor that is provided by a weather station, but can be used for many different things.
