1
Open Automations
Go to Settings → Automations & scenes. Select Create automation → Create new automation.
2
Choose when it runs
Add a trigger under When, such as a time or a supported entity changing state. Start with one simple trigger.
3
Choose what happens
Under Then do, add an action supported by your entity. For example, choose a light’s turn-on action and select that light as the target.
4
Save the automation
Select Save and give it a clear name. Leave it enabled so Home Assistant can respond to its trigger.
5
Check it works
Cause the trigger to happen and check the device’s response. Open the automation’s trace if you need to see which steps ran.
Your connected entity can now take part in Home Assistant automations.
Some entities only report a reading. Use those as triggers or conditions, and choose a controllable entity for an action.
