Home Assistant 2026.5.0 has introduced a built-in dashboard called "Maintenance", initially showing battery states. This means that Maint users can have two dashboards with the same name in the sidebar:

Describe the solution you'd like

Any solution that allows for not having two dashboards with the same names would work. Possibilities may be one or more of the following, or something else:

• Rename the panel (easy but risk of a future name collision)
• Add Maint configuration to set the panel name
• Migrate the frontend from a panel to a custom strategy, one or more cards, or other element type. (Custom strategies are new in 2026.5. A card fully replicating the panel, would allow adding as single-card view or subview in any other custom dashboard)
• Extend the built-in Maintenance dashboard (if possible, may need capabilities in HA)
• Provide the frontend in a separate repository or as a sample.
• Provide actions to manipulate maint entities. This would also allow scripts/automations to adjust entities, e.g. "Mow the lawn" based on weather

Describe alternatives you've considered

• Hiding one of the two dashboards isn't viable because both are valuable
• Renaming the built-in Maintenance dashboard is possible in 2026.5 but is not future-proof; the name and roadmap indicate a desire to extend that dashboard in the future
