The power available in a RasPi is way overkill for "give my plants half a cup of water every day" projects too. I don't need four cores and dual HDMI outputs to tell a motor to spin for half a minute once a day.

I'm just building a outside watering system. I was going to use a RasPi, simply so that it can log the things like temperature, light levels, rainfall, and water butt levels that it uses to work out how much water to dole out, and so that I can log in remotely and change the settings. But there's a shortage and I ended up getting an Arduino instead. It can do everything I need except data logging and remote access, but those don't matter so much.

RasPi should be split into two camps - one being a system for people who want to build a small computer, with decent speed, RAM, real time video decoding, etc, and the other for people who just need a slow low power device with Linux that has GPIO.

You could also use a $1 ESP8266 or a slightly more expensive ESP32.

While that looks like a very nice chip, it still doesn't have ethernet or non-volatile storage, so it doesn't help with remote access or logging.
