HA message today:
Your YAML dashboard configuration uses the old mode: yaml option, which will be removed in Home Assistant 2026.8. Your YAML dashboards will continue to work, you just need to update their definition.
To update your configuration:
Remove mode: yaml from lovelace: in your configuration.yaml
Instead, add a dashboard entry:
lovelace:
resource_mode: yaml
dashboards:
lovelace:
mode: yaml
filename: ui-lovelace.yaml
title: Overview
icon: mdi:view-dashboard
show_in_sidebar: true
Restart Home Assistant
Note: resource_mode: yaml still loads resources from YAML. If you want to manage resources via the user interface instead, you can remove this line and move your resources to Settings → Dashboards → Resources.
