Add device
The Add device action enables the join permission of a Xiaomi Aqara Gateway for 30 seconds. During that time, you can add a new device by pressing its pairing button once.
This is useful for pairing a new sensor or switch without opening the Mi Home app.
Using this action from the user interface
If you prefer building automations and scripts visually, Home Assistant walks you through this action step by step. You pick what to target, tweak a few options, and save. No YAML knowledge required.
To open the gateway for pairing from an automation or a script:
- Go to Settings > Automations & scenes.
- Open an existing automation or script, or select Create automation > Create new automation.
- If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger. They run when something else calls them.
- In the Then do section, select Add action.
- From the search box, search for and select Xiaomi Gateway (Aqara): Add device.
- Enter the Gateway MAC.
- Select Save.
This action does not support targets. In the UI, you are not prompted to choose an area, device, entity, or label.
