I have not maintained my HA for a couple of months/years now. Updates yes, but I have not checked for errors or warnings.
Now when I open up my dashboard I see an error I cannot trace from where it results.
Everything I see is this:
[547177568896] Error during service call to input_select.set_options: Duplicated options: ['lovelace', 'map', 'mushroom-strategy', 'lovelace', 'refresh']
How the heck do I find out where I misconfigured a file I’ve touched years ago?
I checked my automations.yml and other places, but I cannot find this.
It would seem you have installed some custom theme or dashboard (via HACS?) at some point that auto creates an input select helper from your existing dashboards, so presumably you could change dashboard from the frontend. The ‘refresh’ option either updates the helper, or perhaps refreshes the dashboard? This is definitely not a core feature by the way.
I’m absolutely speculating here, but it’s probably choking on the new to 2026.2 default overview dashboard and the legacy one, deriving them both as ‘lovelace’ and trying to add that twice as an item for the auto created input select, which obviously won’t work.
Yes this is correct. I found that installed in HCAS was indeed a default dashboard addon that I must have added 3 yrs ago. Once I deleted this the error was fixed.
