+This filter uses two time delays: on and off.
+
+If the delays are equal, then you can configure the filter in short form by passing the time parameter:
+
+.. code-block:: yaml
+
+    binary_sensor:
+      - platform: ...
+        # ...
+        filters:
+          - delayed_on_off: 1s
+
+(**Required**, time, :ref:`templatable <config-templatable>`): ON and OFF delay.
+When using a lambda call, you should return the delay value in milliseconds.
 **Useful for debouncing binary switches**.
 
+If the delays are different, then you need to pass them as in the example below:
+
+.. code-block:: yaml
+
+    binary_sensor:
+      - platform: ...
+        # ...
+        filters:
+          - delayed_on_off:
+              time_on: 10s
+              time_off: 20s
+
+Configuration variables:
+
+- **time_on** (**Required**, time, :ref:`templatable <config-templatable>`): ON delay.
+- **time_off** (**Required**, time, :ref:`templatable <config-templatable>`): OFF delay.
+
+When using a lambda call, you should return the delay value in milliseconds.
