If you have documentation recommendations, Im all ears, but I am not the type to do video tutorials.
Unfortunately you aren't going to find an easy solution for this unless you use a rolled solution like OpenHab, HomeAssistant, etc. where someone else runs the cloud implementation pieces. Google's entire implementation is geared toward cloud based commercial development partners, not do-it-yourself implementations. If you want a standalone fulfillment like this: its gonna be rough.
