Irrigation with ESPHome and Home Assistant

About

This package includes everything you need to setup an irrigation controller based on ESPHome and HomeAssistant. The automation runs entirely on the ESP device. Also the programming is persistently stored on the ESP device (even during a power-cycle). Home Assistant just provides the frontend to send the programmed values.

Installation

This package includes three directories:

• ./esphome

  This is the EspHome configuration file. Copy irrigation.yaml to your EspHome folder (/esphome in your Home Assistant configuration folder if you use the EspHome Addon for Home Assistant).

  Make adjustments for your ESP device and Wifi and program your ESP device.

• ./config

  These are the Home Assistant configuration files which include some helper entities and automations for the frontend. Copy everything to /packages/irrigation/config within your Home Assistant configuration folder.

  Add the following snippet to your configuration.yaml:

  homeassistant:
    packages:
      irrigation: !include_dir_merge_named packages/irrigation/config/

• ./dashboard

  This folder contains an example for a lovelace dashboard shown in the picture above.

  Copy dashboard.yaml to /packages/irrigation/dashboard within your Home Assistant configuration folder.

  Add the following snippet to your configuration.yaml:

  lovelace:
      mode: storage
      dashboards:
          lovelace-yaml:
          mode: yaml
          title: Irrigation
          icon: mdi:sprinkler-variant
          show_in_sidebar: true
          filename: packages/irrigation/dashboard/dashboard.yaml

  Note: You need to install the multiple-entites-row element and add it as a resource to your Home Assistant installation for the dashboard to function properly.

Restart Home Assistant so that the changes take effect.
