Are you trying to copy my example? I see you have custom: select-list-card
instead of custom: list-card
Thanks Dave, I tried both but none worked?
I take it you have the custom card installed via HACS and have refreshed your browser?
After all this time turns out that Feedparser install was at fault, I had everything correct but it wouldn’t work, So last night I just deleted feedparser and reinstall it and it just started working.
