OpenSprinkler Integration for Home Assistant

Last tested on OS API 2.2.0 and Home Assistant 2024.2.0

Features

Binary sensors for station and programs to show running state
Sensors for each station to show status
Sensors for water level, last runtime and rain delay stop time
Switches for each program and station to enable/disable program or station
Switch to enable/disable OpenSprinkler controller operation
Services to run and stop stations
Service to run programs
Services to pause, set a rain delay, and set the water level.

To have a Lovelace card for the UI, opensprinkler-card can be used.

Installation

Install using HACS. Or install manually by copying custom_components/opensprinkler folder into <config_dir>/custom_components
Restart Home Assistant.
In the Home Assistant UI, navigate to Configuration then Integrations. Click on the add integration button at the bottom right and select OpenSprinkler. Fill out the options and save.
- URL - Should be in the form of http://<ip or host>:<port>. The port can be omitted unless you have changed it, as the default port for OpenSprinkler is 80. SSL (HTTPS) is also supported.
- Password - The OpenSprinkler controller password.
- Verify SSL Certificate - If the integration should verify the certificate from an HTTPS server. Generally, this should be left checked.
- MAC Address - MAC address of the device. This is only required for firmware below 2.1.9 (4), otherwise it can be left blank.
- Controller Name - The name of the device that appears in Home Assistant.

Upgrading from pre 1.0.0

Note: 1.0.0 has major breaking changes, you will need to update any automations, scripts, etc

Remove YAML configuration.
Uninstall using HACS or delete the hass_opensprinkler folder in <config_dir>/custom_components
Restart Home Assistant
Follow installation instructions above

Breaking Changes

Program binary sensors now show running state instead of operation state. Please use the program switch states for program operation state.
Controller binary sensor is removed. Please use controller switch state for controller operation state.
Station switches now enable/disable instead of run/stop stations. Please use opensprinkler.run and opensprinkler.stop services to run and stop stations.
All scenes are removed. Please use the opensprinkler.run service to run programs.

Using Services

Available services are opensprinkler.run for programs, stations and controllers (for running once program), and opensprinkler.stop for stations or controller (to stop all stations).

Run Examples

Run Program Example

service: opensprinkler.run
data:
  entity_id: switch.program_name # Switches or sensors for programs

Run Station Example

service: opensprinkler.run
data:
  entity_id: switch.station_name # Switches or sensors for stations
  run_seconds: 60 # Seconds to run (optional, defaults to 60 seconds)

Run Once Program Example

To run an once program, the run seconds can either be a list of seconds per station or a list of index and second pairs. The following examples are all equivalent.

service: opensprinkler.run
data:
  entity_id: switch.controller_name # Switches or sensors for controller
  run_seconds: # Seconds to run for each station (required)
    - 60
    - 0
    - 30

service: opensprinkler.run
data:
  entity_id: switch.controller_name # Switches or sensors for controller
  run_seconds: # List of station index and run seconds pairs (required)
    - index: 0
      run_seconds: 60
    - index: 2
      run_seconds: 30

service: opensprinkler.run
data:
  entity_id: switch.controller_name # Switches or sensors for controller
  run_seconds: # Dictionary of station index and run seconds key/value pairs (required)
    0: 60
    2: 30

By default running once program will stop all other stations that are running, you can specify continue_running_stations to true to allow the stations to continue running. This only works when specifying the run seconds in index/second pairs.

service: opensprinkler.run
data:
  entity_id: switch.controller_name # Switches or sensors for controller
  run_seconds: # List of station index and run seconds pairs (required)
    - index: 0
      run_seconds: 60
    - index: 2
      run_seconds: 30
  continue_running_stations: True # Whether to keep running stations running (optional, defaults to False)

service: opensprinkler.run
data:
  entity_id: switch.controller_name # Switches or sensors for controller
  run_seconds: # Dictionary of station index and run seconds key/value pairs (required)
    0: 60
    2: 30
  continue_running_stations: True # Whether to keep running stations running (optional, defaults to False)

Stop Examples

Stop Station Example

service: opensprinkler.stop
data:
  entity_id: switch.station_name # Switches or sensors for stations

Stop All Stations Example

service: opensprinkler.stop
data:
  entity_id: switch.controller_name # Switches or sensors for controller

Set Water Level Example

This sets the water level to 50%, i.e. all stations will run half of their normally configured time.

service: opensprinkler.set_water_level
data:
  entity_id: sensor.opensprinkler_water_level
  water_level: 50

Set Rain Delay Example

This sets the rain delay of the controller to 6 hours, i.e. all stations will stop and programs will not run until the rain delay time is over.

service: opensprinkler.set_rain_delay
data:
  entity_id: sensor.opensprinkler_rain_delay_stop_time
  rain_delay: 6

Pause Example

This pauses the station runs for 10 minutes (600 seconds), resuming afterwards.

service: opensprinkler.pause_stations
data:
  entity_id: sensor.opensprinkler_pause_end_time
  pause_duration: 600

Reboot Controller Example

This reboots the controller.

service: opensprinkler.reboot
data:
  entity_id: switch.opensprinkler_enabled

Creating a Station Switch

If you wish to have a switch for your stations, here is an example using the switch template and input number. Add the following to your YAML configuration (configuration.yaml).

switch:
  - platform: template
    switches:
      fruits_station:
        value_template: "{{ is_state('binary_sensor.s01_station_running', 'on') }}"
        turn_on:
          service: opensprinkler.run
          data_template:
            entity_id: binary_sensor.s01_station_running
            # Run seconds uses the input_number below.
            run_seconds: "{{ ((states('input_number.s01_station_minutes') | float) * 60) | int }}"
        turn_off:
          service: opensprinkler.stop
          data:
            entity_id: binary_sensor.s01_station_running

input_number:
  s01_station_minutes:
    initial: 1
    min: 1
    max: 10
    step: 1
