Yep, automation is part of the plan, as is additional smoke detectors.
I did look at basement ventilation too and I’m not sure I can do much there since the house is stucco over block (only the interior walls are wood frame). I have an existing vent fan out a window well, but I’d need to figure out how to weather seal it if I wanted to automate that …. Plus there’s no way it’s sufficient for a battery fire
