The time period and/or number of recent state that should be considered is an important factor here. Check the configuration section below for options.

+Both `sensor` and `binary_sensor` are supported as source sensor. A number of characteristics is supported by each, please check below.
 
 Assuming the [`recorder`](/integrations/recorder/) integration is running, historical sensor data is read from the database on startup and is available immediately after a restart of the platform. If the [`recorder`](/integrations/recorder/) integration is *not* running, it can take some time for the sensor to start reporting data because some characteristics calculations require more than one source sensor value.

 The following statistical characteristics are available. Pay close attention to the right configuration of `sampling_size` and `max_age`, as most characterists are directly related to the count of samples or the age of processed samples.
 
+### Numeric Source Sensor

+The following characteristics are supported for `sensor` source sensors:

 | State Characteristic | Description |
 | -------------------- | ----------- |
 | `average_linear` | The average value of stored measurements under consideration of the time distances between them. A linear interpolation is applied per measurement pair. Good suited to observe a source sensor with non-periodic sensor updates and when continuous behavior is represented by the measurements (e.g. outside temperature).

 | `value_min` | The smallest value among the number of measurements.
 | `variance` | The [variance](https://en.wikipedia.org/wiki/Standard_deviation) of an assumed normal distribution from all measurements.
 
+### Binary Source Sensor
+
+The following characteristic are supported for `binary_sensor` source sensors:
+
+| State Characteristic | Description |
+| -------------------- | ----------- |
+| `average_step` | A percentage of time across all stored measurements, in which the binary source sensor was "On". If over the course of one hour, movement was detected for 6 minutes, the `average_step` is 10%.
+| `average_timeless` | The percentage of stored measurements, for which the binary source sensor was "On". Time in on/off states is ignored. If over the course of one hour, a single movement was detected, the `average_timeless` is 33.3% (assuming the stored measurements "Off", "On", "Off"). Equal to `mean`.
+| `count` | The number of stored source sensor readings. This number is limited by `sampling_size` and can be low within the bounds of `max_age`.
