Basic Setup

To apply the Mushroom Strategy to a dashboard:

1. In the UI of the dashboard, select :material-pencil: in the top right corner.

2. If not taken to a Raw Configuration editor, click the three-dot menu in the top right corner.

3. Select Raw configuration editor.

4. Empty the configuration and add the following lines:

   strategy:
     type: custom:mushroom-strategy
   views: []
   

Note

You may see the following error:

 Error loading the dashboard strategy:
     Error: Timeout waiting for strategy
     element ||-strategy-mushroom-strategy to
     be registered

This is mainly because of cache issues or HACS didn't create a reference.
Try clearing the cache of your client and/or re-downloading the strategy from HACS.

If it still doesn't work, please consult guide How to solve: Error loading the dashboard strategy.
