When I started experimenting with programming languages like BASIC and later C, the concept of if-then-else conditionals was a fundamental aspect that stuck with me. Over the last twenty years, this basic conditional statement has remained an essential tool in my programming repertoire. After migrating most of my automations from Node-RED to the Home Assistant Dashboard, I found myself missing this straightforward conditional logic. Although the Choose action in Home Assistant enables creating anything from basic to complex if-then-else structures, I always wished for a more streamlined and cleaner method. It seems I wasn’t alone in this desire. With the release of Home Assistant Core 2022.5, our requests have been answered. Home Assistant now supports a native if-then-else action. While this new feature doesn’t introduce any functionality that wasn’t already possible, it significantly simplifies and accelerates the process of creating automations.

Understanding the If-Then-Else Action in Home Assistant
The new if-then-else action in Home Assistant allows users to define automations with a straightforward conditional structure. Here’s a basic rundown of how it works:
- If Condition: This is the primary condition that needs to be met for the subsequent actions to be executed.
- Then Action: If the condition is met, the actions specified here will be executed.
- Else Action: If the condition is not met, the actions specified here (if any) will be executed.
Example Scenario
Let’s consider a simple example: turning on a light based on the time of day. Previously, this could be achieved using the Choose action, but the new if-then-else structure makes it more intuitive.
Before (Using Choose Action)
choose:
- conditions:
- condition: time
after: '18:00:00'
sequence:
- service: light.turn_on
entity_id: light.living_room
default:
- service: light.turn_off
entity_id: light.living_roomNow (Using If-Then-Else Action)
if:
- condition: time
after: '18:00:00'
then:
- service: light.turn_on
entity_id: light.living_room
else:
- service: light.turn_off
entity_id: light.living_roomAs you can see, the if-then-else action reduces complexity and makes the automation script more readable.
Benefits of Using If-Then-Else Actions
One of the primary benefits of the if-then-else action is the simplification it brings to creating automations. The syntax is more straightforward, reducing the learning curve for new users and speeding up the process for experienced ones.
By using if-then-else actions, the logic of your automations becomes more apparent. This enhanced readability is beneficial not only for your understanding, but also for anyone else who might interact with your Home Assistant configurations.
Simpler and more readable automations are easier to maintain. When you need to make changes or troubleshoot issues, the if-then-else structure allows you to quickly identify the logic and understand how different conditions and actions are linked.
Conclusion
The introduction of if-then-else actions in Home Assistant Core 2022.5 is a significant improvement, making the creation of automations more intuitive and efficient. This feature simplifies the process, enhances readability, and improves maintainability, making it a valuable addition for both novice and experienced Home Assistant users. Now, creating complex automation flows is easier and more accessible, empowering you to better manage and automate your smart home environment.
