Garden Sprinklers System is a DIY irrigation project for automating the garden watering setup at home. It started in 2021 with a more manual, non-remote setup and was later upgraded in 2025 with Zigbee smart control, Home Assistant integration, and remote automations.

Five separate watering lines

The system is split into 5 separate sprinkler lines, each controlling a different part of the garden and using different sprinkler types depending on the area. This makes the watering more flexible, because each zone can run independently instead of treating the whole garden as one circuit.

Smart valve control

The automation uses Sonoff SWV-BSP smart Zigbee electrovalves to control the water lines. Each valve can be triggered remotely and integrated into Home Assistant, turning a simple irrigation setup into a controllable smart home system.

Home Assistant automations

Home Assistant is used as the main control layer for schedules, manual overrides, and automation logic. This makes it possible to water different zones at different times, avoid running everything at once, and adjust the system more easily as the garden changes.

DIY upgrade path

What makes this project interesting is the progression from a basic physical sprinkler setup into a connected irrigation system. It combines plumbing, electrical control, Zigbee devices, and Home Assistant automations into a practical smart home project that solves a real daily problem.
