Still, I'm not quite ready to give up on computer-controlled automation.
Does anyone know of a reasonably complete guide (web site, book, whatever) that explains this well? What I'm looking for: help choosing components that will work together; not "for dummies"; I'm technically competent and willing to learn some stuff but don't want to make a hobby/profession out of this; doesn't require buying into Google Home, Alexa, or another privacy-hostile system.
Thanks in advance.
