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+.
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?
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.
