:seedling: Smart Garden Irrigation V1.0 beta

:droplet: Automatic and manual control of your garden irrigation — all in one blueprint!

:warning: Note:
This blueprint is currently in beta, as the full range of features has not yet been completely tested.

If you encounter any issues or have suggestions for improvement, feel free to reach out!
I’m happy to help with troubleshooting and will do my best to implement your feedback in future versions.

Open your Home Assistant instance and show the blueprint import dialog with a specific blueprint pre-filled.

“In German language” – the English version follows below.

:sparkles: Features

  • :shower: Zone control: Supports lawn, raised bed, vegetables & shrubs — individually configurable.

:arrow_right: All parameters configurable via UI.
:arrow_right: Defaults (e.g. duration, thresholds) can be adjusted anytime.
:arrow_right: Notifications sent to notify.notify by default — can be customized in the blueprint.

:white_check_mark: Requirements for the Blueprint

:rocket: Smart Garden Irrigation with Flexible Start Time

This blueprint gives you flexible control over your irrigation system, but to use it effectively, several requirements must be met in your Home Assistant setup.

1. :house: Home Assistant Installation

You need a working Home Assistant instance (e.g., on a Raspberry Pi, NAS, or using Home Assistant OS).

2. :hammer_and_wrench: Access to YAML Editor

To import or manually insert the blueprint, you must have access to the YAML editor in Home Assistant:
Settings → Automations & Scenes → Blueprints → Import / Upload

3. :control_knobs: Input Selects for Manual Control

You need to create input_select entities for each irrigation zone. Example:

input_select:
  lawn_control:
    name: Lawn Control
    options:
      - "Stop"
      - "Start"

Create more zones like flowerbed_control, vegetable_garden_control, etc., using the same structure.

4. :seedling: Sensors (Optional but Recommended)

Depending on the features you want to use, the following entities may be needed:

Feature Required Entity Type
Soil Moisture sensor.soil_moisture_zone1 Sensor (percentage)
Rain Detection binary_sensor.rain_detected Binary sensor (on/off)
Water Level Monitoring sensor.water_level Sensor (percentage/L)
Pump Control switch.irrigation_pump Switch
Time-Based Control Automation with time triggers -

5. :toolbox: Manual Controls (Optional)

You can create buttons or a Lovelace dashboard interface for manual zone control.

6. :gear: Automations & Scenes

When setting up the automation using the blueprint, make sure to assign the correct entities (e.g., switches, sensors, input selects).

7. :globe_with_meridians: Internet Connection (if using external services)

If you plan to use external weather data (e.g., from OpenWeatherMap), you’ll need a corresponding integration and API access.

:herb: Guide: Smart Garden Irrigation with Flexible Start Time

This guide walks you through the complete setup of the
“:rocket: Smart Garden Irrigation with Flexible Start Time” blueprint in Home Assistant — including import, configuration, and testing.

:clipboard: Table of Contents

  1. Import the Blueprint
  2. Create Input Selects (for Zone Control)
  3. Set Up Sensors & Devices
  4. Create Automation Using the Blueprint
  5. Lovelace Dashboard (Optional)
  6. Function Test & Troubleshooting

1. :inbox_tray: Import the Blueprint

  1. Open Home Assistant
  2. Navigate to: Settings → Automations & Scenes → Blueprints
  3. Click “Import Blueprint”
  4. Paste the blueprint URL or YAML code
  5. Click “Import”

:arrow_right: The blueprint will now be available when creating a new automation.

2. :control_knobs: Create Input Selects (for Zone Control)

These allow manual control per zone. Add the following to your configuration.yaml or create them under
Settings → Devices & Services → Helpers:

input_select:
  lawn_control:
    name: Lawn Control
    options:
      - "Stop"
      - "Start"

  flowerbed_control:
    name: Flowerbed Control
    options:
      - "Stop"
      - "Start"

:pushpin: Create one input_select per irrigation zone.

:arrow_right: Restart Home Assistant if you added this via configuration.yaml.

3. :seedling: Set Up Sensors & Devices

Feature Entity Type Example
Soil Moisture sensor.soil_moisture_* Sensor (%) sensor.soil_moisture_zone1
Rain Detection binary_sensor.rain_detected Binary sensor (on/off) e.g., from a weather integration
Water Level sensor.water_level Sensor (% or liters) Sensor in a rainwater tank
Pump Control switch.irrigation_pump Switch Smart plug or relay control

:arrow_right: Set up your devices/sensors via integrations or ESPHome.

4. :gear: Create Automation Using the Blueprint

  1. Go to: Settings → Automations & Scenes → Add Automation
  2. Select “Use Blueprint”
  3. Choose the blueprint: “Smart Garden Irrigation with Flexible Start Time”
  4. Fill out the fields:
    • Which input_select zones to control
    • Optional: rain, moisture, and water level sensors
    • Enable automatic start?
    • Set watering times and durations
  5. Click Save

5. :bar_chart: Lovelace Dashboard (Optional)

To enable manual control, add the following card to your dashboard:

type: entities
title: Garden Irrigation
entities:
  - entity: input_select.lawn_control
  - entity: input_select.flowerbed_control
  - entity: sensor.soil_moisture_zone1
  - entity: switch.irrigation_pump

:arrow_right: You can also create buttons or use other custom cards.

6. :white_check_mark: Function Test & Troubleshooting

:mag: Testing:

  • Set an input_select to “Start” → the pump/valve should activate.
  • Check sensor readings → irrigation should pause if it’s raining or the soil is moist.
  • Monitor the automation via Logs or Developer Tools in Home Assistant.

:hammer_and_wrench: Common Issues:

  • Incorrect entity names → verify under Developer Tools → States
  • Missing or unassigned input_select
  • Automation not enabled or incorrectly configured

:tada: Done!

Your smart garden irrigation system is now ready to use.
You can expand it with weather APIs, notifications, or additional irrigation zones at any time.
