HACS custom button not showing up in dashboard?

Today I tried to download custom button for the lovelace UI. it went through and refreshed my screen but it didnt show up when I tried to add the card. I went into my integrations tab and under HACS it only shows 1 entity. but I have sonoff and custom button both downloaded but neither show up. I also was not able to get sonoff integration to work. So I think something is happening btw HACS and my home assistant system. Im running a RP3B+.

I have everything up to date as of today.

If I go into the lovelace UI then to the 3 dots in the right corner and can manage resource and I can see the button addon. But it still does not working if I add a card.
Do I need to add something to the raw code? I thought the new HA and HACS did that for you?

When you go to add a new card, click manual (right at the bottom) and type the config in.

By the way, exactly which card is it? There are many with the word ‘button’ in them. Can you point to the repository?

Integrations and frontend behave differently.

Frontend just requires a reload of the UI, which is usually solved by a popup when adding the frontend module in HACS.
You use therm with card: custom:some-card-name in the beginning, but see the HACS description.

Integrations typical require a multi step process, where you first add them in HACS, then restart HA and then add them on the normal HA integration page.

Button-Card by RomRider. I have tried to do a manual card but it gives me an error.

I have followed your instruction but I still get an error and the custom card does not work.

Does not work is does not exist?

Can you post the error message and your code?

This is the code

type: 'custom:button-card'
entity: switch.switch_hallway_main_1_sonoff
show_icon: false
show_state: true

and this is the error message

‘Custom element doesn’t exist: button-card.’

Your code looks correct and the error also indicate that it is the installation that is bugged.

Have your completely restarted your system?
What does your logs say?
What does your logs say when you open up HACS and download the button-card?

well IT works. I went to the HACS and went to the card and selected redownload. refreshed and it works.

For the record, I had the same problem a couple days ago with the Custom Restriction Card.
Redownload fixed it as well.
