I have a custom dashboard that I created and recently edited while I was accessing HA remotely. When I got home and pulled up a local instance of HA, my custom dashboard would not load and all I could see was “configuration error”. I systematically deleted components of my dashboard, but the error never went away. I also had the same problem with another custom dashboard that I had not edited in over a year. The default dashboard and HA created dashboards (e.g. Energy) work just fine both remote and locally.
Any suggestions?
