You describe it as some sort of heaven, and if that's your thing then (probably) good for you. It wouldn't be for me, I like actually doing things and see these automation as overpriced solution looking for problem that generation ago mostly didn't exist, while folks lived comparably happier lives.

Plus all the time invested into building and maintaining these setups can be measured by tons of fun/adventures missed in ones live. But that's my perspective, I incline more to OP' mindset of needing at most "plant timer".
