  The easiest way to integrate Zwave2Mqtt with Home Assistant is by
  using [MQTT discovery](https://www.home-assistant.io/docs/mqtt/discovery/).
  This allows Zwave2Mqtt to automatically add devices to Home Assistant.
  +To enable this feature remember to set the flag **Hass Descovery** in Gateway settings configuration.
  To achieve the best possible integration (including MQTT discovery):
  -- In your **Zwave2Mqtt** gateway settings enable `Homeassistant discovery` flag
  +- In your **Zwave2Mqtt** gateway settings enable `Homeassistant discovery` flag and enable the MQTT **retain** too. The retain flag for MQTT is suggested to be sure that, once discovered, each device get the last value published (otherwise you have to wait for a value change)
