This is a home grinder, usually grinding for an espresso last less than 30 seconds, it will have time to cool down, no issue there Many grinders like the Niche have a similar on/off switch.
Thank you for your detailed answer. Obsidian Markdown Export makes most of what I need: it created a new note, and transcluded page are copied. So with minimal editing I get what I need. I can merge all the notes of one month in one doc, tidy-up and done. Good opportunity to review note at the same time.
I have a weekly page that transclude (show a section of another page ![[other_page#section]]) notes from daily pages.
Is is possible to copy all the content from the daily page in the weekly? Via a script / extension?
I could copy by hand of course, but I'd like to keep only some info to cleanup the journal pages after a while.
