Color name between ‘’ works

Is it possible to change font color? I have tested several metods and nothing works.

the card is great and works like a charm. I use it mainly to display solar and electric car battery status.
The only limitation I have: instead of an icon I want to display an svg or png image. Any idea if feasible and how to do that?

The same here.
Stopped working after CORE/os upgrade.

Getting ‘ Custom element doesn’t exist’ error on the dashboard

Exactly the same problem since yesterday, after reboot the card cannot be found in lovelace. Tried to remove and HACS re-install, error persists.
Really annoying after all the work spent especially on this great UI component. Any ideas how to recover?

Getting an error after latest HA update these cards are having issues loading

opened 03:01AM - 19 Mar 24 UTC

Since the latest HA frontend and supervisor update i am experiencing a lot of er…rors, one of those things is that the horseshoe cards are not wanting to load when i first navigate to a page on the dashboard, It is not until i refresh that they load. This was not an issue prior to updating. Strangely one of the cards i had for a PC in my home just disappeared for no reason..there are some other things that have disappeared as well so the disappearance may be related to the update, but just mentioning it here. I see this error message in the logs. Logger: frontend.js.latest.202403070 Source: components/system_log/__init__.py:306 First occurred: 5:13:44 PM (3 occurrences) Last logged: 9:56:16 PM Uncaught error from Chrome 122.0.0.0 on Windows 10 TypeError: Cannot read properties of undefined (reading 'substr') FlexHorseshoeCard._colorToRGBA (/hacsfiles/flex-horseshoe-card/flex-horseshoe-card.js:1952:24) FlexHorseshoeCard._getGradientValue (/hacsfiles/flex-horseshoe-card/flex-horseshoe-card.js:1893:33) FlexHorseshoeCard._calculateStrokeColor (/hacsfiles/flex-horseshoe-card/flex-horseshoe-card.js:1822:17) set hass (/hacsfiles/flex-horseshoe-card/flex-horseshoe-card.js:783:29) createCardElement (src/panels/lovelace/cards/hui-stack-card.ts:107:21) createCardElement (src/panels/lovelace/cards/hui-stack-card.ts:124:27) createCardElement (src/panels/lovelace/cards/hui-stack-card.ts:113:13) dispatchEvent (src/common/dom/fire_event.ts:76:7) tag.includes (src/panels/lovelace/create-element/create-element-base.ts:136:14)

Great, that solved it! Thx a lot

I’m losing my mind here. How does one get this card installed? Every single thing I’ve tried just gets me nowhere.

I’ve installed through HACS and tried adding the resources to the resource list (dashboard, menu, resources, etc.). Nothing
I’ve downloaded it separately and put it in the custom components folder and added the references to the resource list (even tried in the configuration.yaml). Nothing

Can anyone explain the process in detail and with examples, because I must be missing something obvious. Every other custom card simply installs and is usable.

Please?

hi all,

i’ve been maintaining HA on two of my friends sailingboats. both have they horseshoe card on the dash. does this card only works when there is an active internet connection ? both have lte routers and when offshore they lose connection and they go local. got the ‘complaint’ that this card gave an error when offshore. might be related to the loss of an internet connection ?
many thanks

Yes, it seems to be dead because it doesn’t work for me either, and the github issues are similar. Seems to be breaking with every Home Assistant update.
