 integration for Home Assistant allows you to connect many off-the-shelf Zigbee based devices to Home Assistant, using one of the available Zigbee radio modules that is compatible with [zigpy](https://github.com/zigpy/zigpy) (an open source Python library implementing a Zigbee stack, which in turn relies on separate libraries which can each interface a with Zigbee radio module a different manufacturer).

 ## ZHA exception and deviation handling
 
-Zigbee devices that deviate from or do not fully conform to the standard specifications set by the [Zigbee Alliance](https://www.zigbee.org) may require the development of custom [ZHA Device Handlers](https://github.com/dmulcahey/zha-device-handlers) (ZHA custom quirks handler implementation) to for all their functions to work properly with the ZHA integration in Home Assistant. These ZHA Device Handlers for Home Assistant can thus be used to parse custom messages to and from Zigbee devices.

 The custom quirks implementations for zigpy implemented as ZHA Device Handlers for Home Assistant are a similar concept to that of [Hub-connected Device Handlers for the SmartThings Classics platform](https://docs.smartthings.com/en/latest/device-type-developers-guide/) as well as that of [Zigbee-Shepherd Converters as used by Zigbee2mqtt](https://www.zigbee2mqtt.io/how_tos/how_to_support_new_devices.html), meaning they are each virtual representations of a physical device that expose additional functionality that is not provided out-of-the-box by the existing integration between these platforms.
