There is a button in the 3 dot menu on each card to Clean Build Files. Is that not what you are requesting?

Hi, thanks I didn't notice this option before.

I cleaned all my build files using the above and used space went from 9.5GB to 7.7GB.

root@esphome:/config/.esphome# du -skh *
122M	build
276K	idedata
7.7G	platformio
48K	storage

root@esphome:/config/.esphome/platformio# du -skh *
1.3G	cache
6.5G	packages
12M	platforms

There is still a lot of space in use, I think it would be nice to add an option to clean all build files and clean all cache maybe?
