# ZHA Integration

## 1. Prerequisite:

Before you begin, please ensure that you have accessed the Home Automation (HA) page. If you are not familiar with how to access the HA service on your iSG device, I recommend referring to the following article ([Start Home Assistant](/isg/advanced-features/home-assistant/accessing-home-assistant.md)), which provides detailed steps and instructions on how to access the HA service.

## 2. To add the Zigbee service: 

1. Click on Settings - Devices & services - ADD INTEGRATION - search for ZHA - select "Zigbee Home Automation."
