+
+About
+-----
+
+The ``ZigbeeAnalog`` class provides analog input and output endpoints for Zigbee networks. This endpoint implements the Zigbee Home Automation (HA) standard for analog signal processing and control.
+Analog Input (AI) is meant to be used for sensors that provide an analog signal, such as temperature, humidity, pressure to be sent to the coordinator.
+Analog Output (AO) is meant to be used for actuators that require an analog signal, such as dimmers, valves, etc. to be controlled by the coordinator.
+
+
