Almost same question, but quite tangential: I'd like to have a plant watering system with least complexity involved. I would assume a fish tank pump plugged into any PC. The plugging part however is not quite-well thought out, neither the output to multiple pots. Could you suggest some ideas? Arduinos, valves, etc? The watering is not automatic and should happen with a push of a PC keyboard key.

I recommend you look into Blumats [1] - no electronics required watering system. [1] https://blumat.com/ https://blumat.com/

I’ve recently contemplated a submersible pump in a bucket (to limit the water in the event of a leak), and just using one of those $10 cloud-enabled switchable plug outlets, with fan-out drip tubing and a suitably-sized flow regulators going to each plant. Eventually perhaps building in some moisture sensors and some pi/arduino logic to then control the pump.

You can get watering timers in home depot, you could try hacking one of those? The hard piece to get is probably the electronic valve.

The easiest solution would be to buy a smartplug and integrate it into one of the smarthome ecosystems like Google Home, Amazon Alexa, Apple HomeKit. For a more DIY solution you can install Node-RED onto a Raspberry Pi for a GUI flow editor: https://hackaday.com/2020/01/15/automate-your-life-with-node-red-plus-a-dash-of-mqtt/ https://hackaday.com/2020/01/15/automate-your-life-with-node... Alternatively, if you'd like to do everything on the Raspberry Pi, use its GPIOs to control a relay module with optocoupler isolation (~$4) which can turn the pump on or off: https://www.aliexpress.com/item/2251832713449142.html https://www.aliexpress.com/item/2251832713449142.html If you're more hardcore, you could flash a smartplug like Sonoff S31 with Tasmota and add rules that trigger based on various events (eg: timer). https://tasmota.github.io/docs/Rules/#rule-variables https://tasmota.github.io/docs/Rules/#rule-variables https://tinkerman.cat/post/sonoff-s31-now-serious https://tinkerman.cat/post/sonoff-s31-now-serious
