When Block ​

When block let's you start an automation when something happens in your system.

Using multiple when blocks ​

You can setup multiple independent flows in the same automation. Simply create additional When blocks. This is useful when you want to create multiple automation flows as a part of a broader automation that you want to do and you want to keep everything in one place.

Sidenote: Adding multiple When blocks is not available if your product variant is limited to only 2 automations.

Listening for multiple triggers in the same When block ​

You can listen for multiple triggers in the same automation.

⚠️ Only one of the triggers needs to be triggered for the automation to run.

Both Date & Time as well as Device Change are used as a trigger.

Trigger types ​

There are multiple types of triggers available:

1. Time & date
2. Device change
3. Listen for KNX telegrams

1. Time, Date, Sunrise & Sunset ​

You can start an automation based on the time or date in the system.

Possible options:

• During the Week - run on selected days of the week at a specific time
• At a Specific Date - run at a specific date at a specific time
• Every Month - run every month on a specific day and time
• Every Hour - run every hour at a specific minute, for example every hour at 30 minutes
• Every Minute - run every minute
• Every Couple of Seconds - run every 5, 10, 20 or 30 seconds
• Sunrise & Sunset - run on a sunrise or sunset at specific days of the week, with a possible before or after offset (up to 4 hours offset). You can also manually set the time & location of the device in case the automatic settings are not accurate enough.

Example: During the week automation trigger.

Example: At sunrise automation trigger.

A preview of when the next automation will be run is also shown (see image above).

2. Device change ​

You can start an automation when a device state changes.

3. Listen for KNX telegrams ​

You can listen for KNX telegrams received on specific group addresses and gateway and use the received value in the automation.

Learn more in the Working with KNX in Automations guide.

Using trigger value in automation ​

Value received in the trigger can be used later within the automation.

It can be used in the Dynamic inputs as shown below. You can quickly identify from which trigger the value was taken by looking at the tag (T1 in example below).

⚠️ Note that if multiple triggers are used, only the trigger that was triggered has a valid value set that you can use in the automation. You can always check which trigger was triggered by using dynamic data of the trigger (triggered value). See how to use Dynamic Data.

Learn more about Dynamic Data in the Using dynamic data guide.
