**Supervisor Panel deprecated in HA 2026.5 — built a replacement**

[grizzled bobcat]

HA 2026.5 removed the hassio-main panel. Restart Core, Restart Supervisor, Reboot Host, and Shutdown Host are gone from the UI. Built a replacement custom sidebar panel using the HA WebSocket API and native System Monitor entities. Will make its way to GitHub and HACS but wanted to get it out for those that need it while waiting for HACS approval.

Install:

1. Create super-panel.js in /config/www/ and paste in the code
2. Add to configuration.yaml:

panel_custom:
  - name: super-panel
    sidebar_title: Supervisor Panel
    sidebar_icon: mdi:home-assistant
    url_path: super-panel
    module_url: /local/super-panel.js
    require_admin: true

3. Full HA restart required

Requires Supervisor — HAOS or supervised install only

It will make its way to github and HACS but I wanted to get it out for those that use it.

I'm not sure what the issue is. You can still reboot and such fine here (top right): https://my.home-assistant.io/redirect/system_dashboard/
I use this to get the Developer Tools menu item back

panel_custom:
  - name: developer-tools
    sidebar_title: Developer Tools
    sidebar_icon: mdi:tools
    js_url: /api/hassio/app/entrypoint.js
    embed_iframe: true

yes thats true. Try to get the supervisor panel back.... it aint there!

[analog wave]

Can you try long pressing the sidebar title and see if it shows up?

It was deprecated. Its gone. HA 2026.5 removed the hassio-main panel registration. The old Supervisor frontend is gone. The restart buttons that used to live there are no longer accessible in the UI.
