This integration is for irrigation systems large and small. It can offer some complex arrangements without large and messy scripts. This integration will complement many other irrigation projects.

Home Assistant makes automating switches easy with the built in tools available. So why this project? You have a system in place but now you have extended it to have a number of zones. You don't want all the zones on at once because of water pressure issues. Maybe you would like each zone to have a number of schedules say a morning and evening watering. What about water restrictions that limit irrigation systems to certain days of the week or days in the month, odd or even for example. Perhaps you would like different schedules for winter and summer. Now you would like to adjust the times based on weather conditions, past, present or future. Let's turn a zone or even a controller off for system maintenance. Starting to sound more like your system? Finally what's going on now and what's up next.

Each controller has an associated (master) sensor which shows on/off status and other attributes. The master will be on when any of its zones are on. The master sensor can have a pre and post amble period to activate or warm up the system like charge up a pump, enable WiFi or turn on a master valve. The master sensor has a number of service calls available to enable/disable all the zones it controls.

Zones also have an associated sensor which, like the master, shows on/off status and various attributes. Zones sensors have service calls that can enable/disable and provide manual runs. Also adjust run times in automation scripts using information from integrations that collect weather data like OpenWeatherMap, BOM, weatherunderground and many others. Go crazy with projects like HAsmartirrigation. Easily integrate probes and sensors from ESPHome for real-time adjustments. Examples provided below.

1. Unlimited controllers.
2. Unlimited zones.
3. Unlimited schedules. Schedule by absolute time or sun events (sunrise/sunset). Select by days of the week (mon/tue/wed...). Select by days in the month (1/2/3.../odd/even). Select by months in the year (jan/feb/mar...). Overlapped schedules.
4. Unlimited sequences. Operate zones one at a time in a particular order with a delay in between. A 'playlist' for your zones.
5. Hardware independent. Use your own switches/valve controllers.
6. Software independent. Pure play python.

*Practical limitations will depend on your hardware.

Irrigation Unlimited is comprised of controllers, zones and schedules in a tree like formation. Each controller has one or more zones and each zone has one or more schedules. Controllers and zones will have a binary sensor associated with each one so they can be intregrated with Home Assistant.

└── Irrigation Unlimited
  └── Controller 1 -> binary_sensor.irrigation_unlimited_c1_m
    └── Zone 1 -> binary_sensor.irrigation_unlimited_c1_z1

          ...
      └── Schedule N
    └── Zone 2 -> binary_sensor.irrigation_unlimited_c1_z2

  └── Controller 2 -> binary_sensor.irrigation_unlimited_c2_m
      ...
  └── Controller N -> binary_sensor.irrigation_unlimited_cN_m
      ...

Controllers and zones can specify an entity such as a switch or light, basically anything that turns on or off the system can control it. This is the irrigation valve. If this does not go far enough for your purposes then track the state of the binary sensors in an automation and do your own thing like run a script or scene.

This component will set up the following platforms.

A binary sensor is associated with each controller and zone. Controller or master sensors are named binary_sensor.irrigation_unlimited_cN_m and zone sensors binary_sensor.irrigation_unlimited_cN_zN. These sensors show the state of the master or child zones. Attributes show additional information like current schedule and next run time and duration.

HACS is the recommended method for installation. If you are having difficulties then please see the troubleshooting guide

1. Just search for Irrigation Unlimited integration in HACS and install it.
2. Add Irrigation Unlimited to your configuration.yaml file. See configuration examples below.
3. Restart Home Assistant.

1. Using the tool of choice open the directory (folder) for your HA configuration (where you find configuration.yaml).
2. If you do not have a custom_components directory (folder) there, you need to create it.
3. In the custom_components directory (folder) create a new folder called irrigation_unlimited.
4. Download all the files from the custom_components/irrigation_unlimited/ directory (folder) in this repository.
5. Place the files you downloaded in the new directory (folder) you created.
6. Restart Home Assistant
7. In the HA UI go to "Configuration" -> "Integrations" click "+" and search for "Irrigation"

Using your HA configuration directory (folder) as a starting point you should now also have this:

custom_components/irrigation_unlimited/__init__.py
custom_components/irrigation_unlimited/binary_sensor.py
custom_components/irrigation_unlimited/const.py
custom_components/irrigation_unlimited/entity.py
custom_components/irrigation_unlilmited/irrigation_unlimited.py
custom_components/irrigation_unlimited/manifest.json
custom_components/irrigation_unlimited/service.py
custom_components/irrigation_unlimited/services.yaml

Configuration is done by yaml. Note: The configuration can be reloaded without restarting HA. See below for details and limitations.

The time type is a string in the format HH:MM. Time type must be a positive value. Seconds can be specified but they will be rounded down to the system granularity. The default granularity is whole minutes (60 seconds). All times will be syncronised to these boundaries.

This is the controller or master object and manages a collection of zones. There must be at least one controller in the system. The controller state reflects the state of its zones. The controller will be on if any of its zones are on and off when all zones are off.

This object is useful when the same settings are required for each zone. It is simply a shorthand or a more concise way to specify the same settings for each zone. The parameter becomes a default which can be overridden in the actual zone.

The zone object manages a collection of schedules. There must be at least one zone for each controller.

Schedules are future events, not dates for example Mondays. There must be at least one schedule for each zone.

The schedule can have the commencement or completion fixed to a time or event with the anchor parameter. Any adjustments to the duration will alter the start time if finish is specified or the completion time if start is specified. Note: If anchoring to finish and the schedule can not complete before the specified time then the run will defer to the following day. This is an important consideration if adjusting run times dynamically as it may lead to a 'skipping' situation. Ensure there is sufficient time to complete the run when making adjustments. See here for more information on adjusting runs times.

The parameters weekday, day and month are date filters. If not specified then all dates qualify.

Leave the time value in the Schedule Objects blank and add the following object. An optional before or after time can be specified.

Sequences allow zones to run one at a time in a particular order with a delay in between. This is a type of watering 'playlist'. If a delay is specified and a pump or master valve is operated by the controller then consider the postamble setting in the Controller Object. Set this to the largest delay to prevent pump on/off operations.

Sequences directly descend from a controller and are loosely connected to a zone entity via the zone_id parameter. The zone_id may point to one or many (a list) zone entities. A zone may be referenced more than once in a sequence.

└── Irrigation Unlimited
      └──> Controller
            ├──> Zones
            │     ├──> Zone 1 <────┐
            │     ├──> Zone 2 <────┤
            │     │     ...        │
            │     └──> Zone N <────┤
            └──> Sequence          │
                  ├──> zone_id >───┤
                  ├──> zone_id >───┤
                  │      ...       │
                  └──> zone_id >───┘

The sequence zone is a reference to the actual zone defined in the Zone Objects. Ensure the zone_id's match between this object and the zone object. The zone may appear more than once in the case of a split run.

Special note for schedules and the duration parameter contained within when used with sequences. Each zone in the sequence will be proportionaly adjusted to fit the specified duration. For example, if 3 zones were to each run for 10, 20 and 30 minutes respectively (total 1 hour) and the schedule.duration parameter specified 30 minutes then each zone would be adjusted to 5, 10 and 15 minutes. Likewise if schedule.duration specified 1.5 hours then the zones would be 15, 30 and 45 minutes. Some variation may occur due to rounding of the times to the system boundaries (granularity). This parameter influences the durations specified in the sequence and sequence zone objects.

The testing object is useful for running through a predetermined regime. Note: the speed value does not alter the system clock in any way. It is accomplished by an internal 'virtual clock'.

This is the test time object. Test times do not alter the system clock so there is no danger of disruption to the Home Assistant system.

These are the expected results from the test object. Every time a controller or zone turns on or off it is compared to the next item in this list. To aid in generating this list from scratch set output_event to true in the Testing Object. Events will be printed to the console which can be copied to this object.

For a more concise style, results can be on one line for example:

results:
  - {t: '2021-01-04 06:00:30', c: 1, z: 0, s: 1}
  - {t: '2021-01-04 06:00:30', c: 1, z: 1, s: 1}
  - {t: '2021-01-04 06:10:00', c: 1, z: 2, s: 1}
  - {t: '2021-01-04 06:10:30', c: 1, z: 1, s: 0}
  - {t: '2021-01-04 06:20:00', c: 1, z: 2, s: 0}
  - {t: '2021-01-04 06:20:00', c: 1, z: 0, s: 0}

This is similar to the above but using sequences in a 3 zone system. Each zone runs for 12 minutes for a total of 36 min (plus delays). In Summer the total duration is extended to 45 minutes and winter reduced to 30 minutes. When using the duration parameter in the Schedule it relates to the total duration of the sequence, each zone is adjusted accordingly.

          - zone_id: 2
          - zone_id: 3
          - zone_id: 4

For a more comprehensive example refer to here.

1. Schedules can not only have a day of week (mon, wed, fri) but also a month of year (jan, feb, mar). This allows the setup of seasonal watering schedules. For example run every day in summer and twice a week in winter. Setup a different schedule for each month of the year using this filter.

2. Use sequences to setup a water saving or eco mode. Eco mode uses small cycles with a delay to allow the water to soak in and minimise run off. Run all the zones for half the time and then repeat.

3. No need to restart HA after changing the configuration.yaml file. Go to Configuration -> Server Controls -> YAML configuration and reloading and press 'RELOAD IRRIGATION UNLIMITED'.

4. After setting up configuration.yaml, the operation can be controlled via service calls as shown below. Perform manual runs, adjust watering times, cancel running schedules and enable/disable zones from a frontend

The binary sensor associated with each controller and zone provide several services. The sensors offer the following services:

• enable
• disable
• toggle
• cancel
• manual_run
• adjust_time

If a controller sensor is targetted then it will effect all its children zones.

Enables/disables/toggles the controller or zone respectively.

Cancels the current running schedule.

Turn on the controller or zone for a period of time. When a sequence is specified each zone's duration will be auto adjusted as a proportion of the original sequence. Zone times are calculated and rounded to the nearest time boundary. This means the total run time may vary from the specified time.

Adjust the run times. Calling this service will override any previous adjustment i.e. it will not make adjustments on adjustments. For example, if the scheduled duration is 30 minutes calling percent: 150 will make it 45 minutes then calling percent 200 will make it 60 minutes. Must have one and only one of actual, percentage, increase, descrease or reset. When a sequence is specified each zone's duration will be auto adjusted as a proportion of the original sequence.

A schedule anchored to a start time will alter the completion time. Likewise a schedule anchored to a finish time will change the commencement time. In this situation ensure there is enough time in the current day for the schedule to complete or it will be deferred to the following day.

Use forecast and observation data collected by weather integrations in automations to adjust the run times. See below for more information.

Reload the YAML configuration file. Do not add or delete controllers or zones, they will not work because of the associated entities which are created on startup. This may be addressed in a future release, however, suggested work around is to set enabled to false to effectively disable/delete. All other settings can be changed including schedules. You will find the control in Configuration -> Server Controls -> YAML configuration reloading. Note: since version 2021.10.0 all settings can be changed including new controllers and zones.

A reminder that sequences directly descend from a controller. Therefore service calls that manipulate a sequence should address the parent controller. An entity_id of a zone when trying to adjust a sequence will most likely not have the desired effect.

The combination of three key parameters entity_id, sequence_id and zones will target the various sections of the configuration.

• entity_id: This will be either the controller or zone entity.
• sequence_id: This is the position number of the sequence under the controller. sequence_id: 1 is the first, 2 is the second and so on.
• zones: This is the position number of the zone reference under the sequence. zones: 1 is the first, 2 is the second and so on. As a shortcut, zones: 0 will alter all zone references in the sequence. May also take a list zones: [1,3,5]

The following is a valid irrigation unlimited configuration. It shows how various points can be changed using the service calls above. Example numbers have the nomenclature C.Z.S.R = Controller.Zone.Sequence.zoneReference. If Z is zero then the entity_id must be the controller/master i.e. binary_sensor.irrigation_unlimited_cN_m. If Z is not zero then then entity_id is the zone i.e. binary_sensor.irrigation_unlimited_cN_zN.

Because this is an integration there is no frontend. For an out-of-the-box vanilla solution, simply put the master and zone binary sensors onto an entity card to see what is going on. However, for some inspiration and a compact card try this.

and it expands to:

Note: This card uses some custom cards multiple-entity-row, fold-entity-row, logbook-card and at the moment card-mod for styles.

For watering history information here is a sample card.

.

Note: At time of writing this requires a pre-released version of mini-graph-card. Note: If you get "NaN" displayed instead of the actual value then clear out your browsers cache.

Although not really part of the integration but to get you started quickly here is a temperature card.

.

And a rainfall card. Note how the watering times reduced as rainfall started. More on this below in Automation.

Finally, a system event log

Putting it all together, here is the complete picture

This configuration is three vertical stacks and works well on mobile devices.

Here is a card for manual runs. You can find the code here. Note: This card uses paper-buttons-row because it can create a button without the need for an actual entity.

There is a support file packages/irrigation_unlimited_controls.yaml which should go in the config/packages directory. Also required is a pyscript which is called from the above automation to populate the input_select with all the irrigation unlimited controllers and zones. The script should go in the config/pyscript directory. If you don't have a packages or pyscript folder then create them and add the following to your configuration.yaml. Minimun version 2021.6.3 for Irrigation Unlimited is required.

homeassistant:
  packages: !include_dir_named packages

More information on packages can be found here and pyscript can be found here, don't worry about the Jupyter kernel unless you are really keen. Hint: A pyscript is used instead of Jinja2 as it produces a list which Jinja2 is not capable of, many have tried...

Due to the many weather integrations available and their relevance to your situation, there is realistically no way to provide a built in 'auto-adjustment' feature. Therefore, no attempt has been made to include a solution and this also makes the integration more independant and flexible. Run time adjustment is achieved by setting up sensor(s) that consume weather information such as rainfall and temperature but could factor in wind speed, solar radiation etc. to determine if more or less watering time is required. You might also consider using forecast information... A service call is then made to irrigation unlimited to adjust the run times. This does mean some knowledge of creating automations is required.

On a personal note, I use the national weather service BOM for my forecast information but find their observation data not relevant due to the extreme regional variations in my situation. There are many micro climates (mountains) and a few kilometers in any direction makes a lot of difference, down pour to a few drops. To this end I have a Personal Weather Station (PWS) that feeds Weather Underground where I use the WUnderground integration to retrieve the data.

You will find my adjustment automation here which feeds off the temperature and rainfall observation data. There is a card here which displays this information (uses multiple-entity-row). Some ideas were gleaned from kloggy's work.

This example uses the data from a soil moisture probe created in ESPHome to adjust the run times.

automation:
  - alias: ESPHome soil moisture adjustment
    trigger:
      platform: state
      entity_id:
        - sensor.yard1_humidity
    action:
      service: irrigation_unlimited.adjust_time
      data:
        entity_id: binary_sensor.irrigation_unlimited_c1_m
        percentage: >
          {# Threshold variable 0-100 percent #}
          {% set threshold = 40 %}

          {# Sensor data #}
          {% set humidity = states('sensor.yard1_humidity') | float %}

          {% if humidity < threshold %}
            {# Option 1 - A linear sliding scale #}
            {% set multiplier = 1 - (humidity / threshold) %}
            {# Option 2 - On or Off #}
            {% set multiplier = 1.0 %}
          {% else %}
            {% set multiplier = 0.0 %} {# It's too wet, turn off #}
          {% endif %}

          {# Return multiplier as a percentage #}
          {{ (multiplier * 100) | round(0) }}

HAsmartirrigation calculates the time to run your irrigation system to compensate for moisture lost by evaporation / evapotranspiration. The following automation runs at 23:30 and takes the calculated run time from HAsmartirrigation and updates Irrigation Unlimited with the new watering time. It then calls HAsmartirrigation to reset the bucket when the irrigation has run.

The example below offers two methods for a single zone or a sequence.

There should be little trouble installing this component, please use the HACS method where possible. Binary sensors are created automatically. However, if you experience difficulties please check the following:

This integration depends on two other components; recorder and history. Both of these components are part of the standard Home Assistant installation and enabled by default with the default_config: line in the configuration. If you have removed this line then a history: and recorder: section must be setup manually. If a mistake is made in either one of these configurations then they will not start and in turn, Irrigation Unlimited for which it depends on, will not start. Please check the log file for the following lines:

2021-08-03 12:12:40 INFO (MainThread) [homeassistant.setup] Setting up recorder
2021-08-03 12:12:40 INFO (MainThread) [homeassistant.setup] Setup of domain recorder took 0.1 seconds
...
2021-08-03 12:12:42 INFO (MainThread) [homeassistant.setup] Setting up history
2021-08-03 12:12:42 INFO (MainThread) [homeassistant.setup] Setup of domain history took 0.0 seconds

The above shows the requirements were loaded successfully. Note: The lines may not be consecutive in the log. If you do not see these lines then go back to basics and remove any history: and recorder: sections and ensure the default_config: line is present. Restart HA and check you have these log entries.

There must be a irrigation_unlimited: section in the configuration. If the section is missing or invalid then Irrigation Unlimited will not start. Check the log file to see it successfully started up.

2021-08-03 12:12:45 INFO (MainThread) [homeassistant.setup] Setting up irrigation_unlimited
...
2021-08-03 12:12:47 INFO (MainThread) [homeassistant.setup] Setup of domain irrigation_unlimited took n.n seconds

The above shows that Irrigation Unlimited loaded successfully. Note: The lines will most likely not be together so do a search. If it failed then use the minimal configuration shown here. This is a good starting point to get aquainted with this integration.

For more detailed information set your logging for the component to debug:

logger:
  default: info
  logs:
    custom_components.irrigation_unlimited: debug

If all else fails please open an issue.
