Used blueprints and it disabled all my automations

I imported a blueprint to have a look at this option. All looked good until I restarted HA and automations disappeared completely with an error.

After trying a few option online, I just deleted the imported blueprint and automations came back fully working.

So confused as to why…

My guess would be that the blueprint had some malformed YAML and that prevented the automations from being read properly.

The blueprint was for showing battery levels?

It doesn’t really matter in what it was for in this case. Malformed code can prevent code that follows from being read properly. I suspect that’s what happened.

OK, thanks for the info and I will be more a wear of which blueprint to use.
