Add-ons won't show in menu

Configuration
1

I can't seem to be able to add any addons which is messing with my ability to configure new WiFi switches (specifically din rail switch which shows up with no entities after loading from Tuya) trying to access it via Tuya Local.

im new to HA so I've been trying to use the Chatgpt advisor for HA
hit a brick wall

here is the basic information:
Home Assistant OS 17.3
Core 2026.6.1
Supervisor 2026.05.1
Frontend 20260527.4

Symptoms:

  • No Add-ons menu
  • /config/addons/dashboard is blank
  • /hassio/store returns 404
  • Home Assistant Supervisor integration is loaded
  • hassio.* services are available
  • Supervisor repositories load successfully

Be advised most on line gpts are woefully behind on thier HA knowledge and will confidently lead you down a bad path.

That said. First what kind of installation do you have (what method) it matters.

HAOS? Core? Or Container?

(hint, two of those do not support Apps)

Add-Ons are now Apps.
The url for installed Apps is: /config/apps/installed.
The url for the App-Store is: /config/apps/available

Thanks!

I only know a "Tuya Local" - Integration, but not an App.
Maybe this could help?

And it came up I'm reading 4 articles at once Ace and you know what the high likelihood was.

Op you sound like you’re confusing App with Integration.

Integration. Think pluggable adapter to make HA do a thing.

App. A self contained server application. (A thing to do. Or be connected to by previous)

Sometimes there will be apps that have thier own integration (Node Red for instance)

Apps - you see where to get those.

Custom Integration - like Tuya are integrations and usually served from HACS. (Home Assistant Community Store) https://www.hacs.xyz/

Install HACS. Go hunt your integration - use the instructions above to install it.
