# Flows Troubleshoot

> Fix issues when Homey Flows can't be triggered from Zendo.

If a Flow doesn't appear or can't be triggered from Zendo, it's usually due to one of the following reasons.

## Flow requires an input value

Some Flows are configured with input arguments (e.g. a text value or a number) that must be provided when the Flow is started. Zendo does not currently support triggering Flows that require input values. As a workaround, create a new Flow that uses the **Start Flow with** card to call the original Flow, passing a specific value for each input argument. You can then trigger this new Flow from Zendo without any issues.

## Advanced Flow missing a Start card

In Homey's Advanced Flow editor, a Flow must have a **Start** card (the play icon) to be triggerable externally. Without it, there is no entry point for Zendo or any other app to start the Flow.

Advanced Flows are a visual, node-based automation editor in Homey. Unlike simple Flows which always have a "When..." trigger, Advanced Flows can contain logic nodes without an explicit start point. If your Advanced Flow was built without a Start card, it cannot be triggered on demand.

### How to fix it

1. Open the **Homey app** or **Homey web interface**.
2. Go to **Flows** and open the Advanced Flow that isn't working.
3. In the flow editor, add a **Start** card (this is the card with the play icon).
4. Connect it to the first action or logic node in your flow.
5. Save the flow.

Once the Start card is in place, restart the Zendo app and the Flow will be available.
