Hey everyone, I’m really excited to share my recent project with ESPHome’s new irrigation component. I’ve been working on an irrigation system for my garden, and I must say, this addition to ESPHome has been a game-changer for me. I have a setup with four valves, and I wanted to automate the watering process without the need for a pump. Here’s how I approached it and the code I came up with.
I started by setting up my ESP8266 with the necessary configurations for my home network. I made sure to enable logging and the Home Assistant API to keep everything integrated smoothly. The main challenge was configuring the sprinkler system correctly. I decided to use four valves, each with its own enable switch and run duration. I also set up GPIO pins for each valve to ensure they functioned independently.
Here’s the code I used for my setup:

I’m really happy with how this setup works. It allows me to control each valve independently and set specific run durations for each section of my garden. I also appreciate the valve_open_delay feature, which ensures that the valves open smoothly without any sudden pressure changes.
I’d love to hear from anyone else who has worked with ESPHome’s irrigation component. Do you have any tips or tricks that could help me optimize this setup further? I’m also curious if others have tried automating their irrigation systems with ESPHome and how their experiences compare. Let’s keep the conversation going and share our smart gardening hacks!
