Does HA need a zigbee adaptor like zigate?

If I start using HA instead of Mi Home, will I need to purchase a zigbee/zigate adaptor or will the Xiaomi gateway allow HA to communicate with the zigbee endpoints?

Yes you need a Zigbee Coordinator adapter if you want to use ZHA integration or Zigbee2MQTT, read:

My recommendation as it stands today is to buy a CC2652P based USB adapter like ITead Sonoff Plus:

Regardless of the adapter you choose be sure to upgrade its firmware + use a USB extension cable, and plug into a USB 2.0 port or via a powered USB 2.0 hub and not a USB 3.0 port due to interference.
