I have been wanting to learn Home assistant and ESP home for a long time and decided to fix this annoying issue as my first project!

I used 2 ESP32s, a 0-10V proportional ball valve and an NTC temp probe. I wanted to measure the outside ground temp to decide when to turn on the ball valve just enough to trickle the water before the ground gets to freezing temperature. Easier ways to do it but I learned a lot more doing it this way!

I made a big dumb video about it too if you're into that kind of thing:
