Irrigo

Irrigo is a garden irrigation system based on ESP32, it is Open Source and compatible with Home Assistant.

These are some interesting features of Irrigo:

  • WiFi connectivity
  • List item
  • Simple Web Interface for configuration
  • MQTT enabled
  • 4 Channels
  • Simple Web Firmware Update
  • Compatible with Home Assistant
  • Flexible
  • Supports 24V AC valves

The necessary hardware is a ESP32 board with at least 4 digital outputs, a relay board and power supply @ 24 VAC for valves. (go to the Wiki for more info) This is a screenshot of the simple Web GUI:

To use it in Home Assistant it is important to have installed the MQTT integration, then in configuration.yaml add the following script:

mqtt:
  switch:
  - name: "Channel 1"
    state_topic: "tele/irrigation/1"
    command_topic: "cmnd/irrigation/1"
    availability_topic: "tele/irrigation/LWT"
    payload_available: "Online"
    payload_not_available: "Offline"
    qos: 1
    payload_on: "ON"
    payload_off: "OFF"
    retain: false
    icon: hass:switch
  - name: "Channel 2"
    state_topic: "tele/irrigation/2"
    command_topic: "cmnd/irrigation/2"
    availability_topic: "tele/irrigation/LWT"
    payload_available: "Online"
    payload_not_available: "Offline"
    qos: 1
    payload_on: "ON"
    payload_off: "OFF"
    retain: false
    icon: hass:switch
  - name: "Channel 3"
    state_topic: "tele/irrigation/3"
    command_topic: "cmnd/irrigation/3"
    availability_topic: "tele/irrigation/LWT"
    payload_available: "Online"
    payload_not_available: "Offline"
    qos: 1
    payload_on: "ON"
    payload_off: "OFF"
    retain: false
    icon: hass:switch
  - name: "Channel 4"
    state_topic: "tele/irrigation/4"
    command_topic: "cmnd/irrigation/4"
    availability_topic: "tele/irrigation/LWT"
    payload_available: "Online"
    payload_not_available: "Offline"
    qos: 1
    payload_on: "ON"
    payload_off: "OFF"
    retain: false
    icon: hass:switch
