Dashboards just installed new dashboard ,cannot open dashboard only add entities,cards option does come up at bottom of page.
New to HA, have i made an error ???
Can you explain the problem a bit more? How did you “install” the new dashboard? You say you can’t open it - what did you do and what did you expect to happen?
The ADD CARD button bottom right means that you are in edit mode. After you’ve added cards, you click DONE (top right) to actually use the dashboard.
