- Add water source monitoring as an attribute of a zone.
- Stop zone attempting to run when the run time is 0.
- Fix custom card deployment.
- Improve treatment of unavailable zone switches.
The driver for this project is to provide an easy-to-use interface for the gardener of the house. The goal is that once the initial configuration is done all the features can be modified using the custom lovelace card.
This program is essentially a scheduling tool, one user has used this to schedule the running of his lawn mower, so the use is far broader than I anticipated.
Watering can occur in an ECO mode where a water/wait/repeat cycle is run to minimise run off by letting water soak in using several short watering cycles. Great for pots.
Supports watering by time or volume.
A number of sensor inputs are available to stop or modify the watering based on external inputs.
- The rain sensor is implemented as a binary_sensor, this allows a sensor to suspend the irrigation. This can be defined at the zone level to allow for covered areas to continue watering while exposed areas are suspended.
- The water adjustment provides for a factor to be applied to the watering time/volume either increasing or decreasing watering based on external inputs
- Scheduling can be configured to support regular watering every number of days or it can be configured to only water on specific days of the week. The schedule can also be supplied by a sensor to allow for changing the watering frequecy automatically based on the season or forecast data.
- The OpenWeatherMap History control provides sensors that may be useful, this provides access to history and forecast weather information to allow you to expose sensors that can be used.
The program issues Home Assistant events so you can undertake other automations if required.
There is also support for a pump or master solenoid, running programs or zones sequentially or concurrently.
The custom card renders the program configuration as a card ans is installed automatically. It exposes in addition to the state of each of the configured helpers:
- the remaining run time for the program and zone
- the last run and/or next run details
This tutorial will get a basic setup running.
- Adding the repository using HACS is the simplest approach. From V5.3 a Custom Card deployed with the component, no need to install separately.
- Make sure that all of the objects you reference i.e. switches, sensors etc are defined or you will get errors when the irrigationprogram is triggered. Check the log for errors.
- Define the program using the UI. From Setting, Devices & Services choose 'ADD INTEGRATION'. Search for Irrigation Controller Component.
- Add the integration many times if you want more than one program.
- Modify programs and zones, add new zones, delete zones
You need to define the entities that allow you to control the features you want. I have have moved away from defining the helpers in YAML and create them via the Helpers tab in the Settings, Devices and services paged, I find it easier and there is no need to restart HA when you add new ones. Create the following for a basic setup.
For the Program create these helpers:
- Input_datetime for the program start time (time only)
- Input_boolean to support the enabling/disabling of the program
- Input_select to define the frequency you want the zone to run, you can do this on the program if you want and save a few entities but I have different frequencies on some zones
For each Zone create these helpers:
- Input_number to provide the duration of the watering cycle
This tutorial will get a basic setup running, have a read of the notes below and try a few of the other features.
testhelpers.yaml provides the helper configuration to support all the objects for three zones. A set of template switches for the zones and pump as well as inputs to emulate rain and flow sensors.
This allow me to test the program without triggering any 'real' solenoids, and will allow you to mimic your configuration in new versions to ensure an operational configuration after coming out your winter hinernation.
Be aware this is a sumulation, variatons in latency or behaviour of indivdual implementations will have an impact.
Add the following to your logger section configuration.yaml
logger:
default: warning
logs:
custom_components.irrigationprogram: debugThe following services support testing and debugging:
- irrigationprogram.reset_runtime service will reset the last run details
- irrigationprogram.run_simulation will list details of the program based on the currently set attributes
If a rain sensor is defined the zone will be ignored when the value of the sensor is True.
If the irrigation program is run manually the rain sensor value is ignored and all zones will run.
The rain sensor is defined in each zone. You can:
- Define the same sensor for each zone
- Have a different sensor for different areas
If the rain sensor (or other sensor) prevents scheduled watering the program will retry the next day.
Watering is by default time based, that is, will run for the minutes set in the water entity.
You can define a flow sensor on a zone that provides a volume/minute rate. eg litres per minute. Once defined the water attribute will be read as volume eg 15 litres not 15 minutes.
You can define the start time using two methods.
- As an input_datetime
- This supports selecting the start time
- As an input_text
- This allows you to input multiple start times for the program
- Time format MUST be hh:mm:00, 24 hour time format with 00 as seconds e.g. 18:55:00
- Each time MUST be seperated by a ','
- Use this regex pattern to help ensure the correct time structure (([0-2][0-9]:[0-5][0-9]:00)(?:,|$)){1,10}
- If no valid time is supplied the start time will be defaulted to 08:00:00
Run frequency allows the definition of when the program will run. This can be provided as dropdown helper or a sensor, see OpenWeatherMap History
Frequency can be set on the zone or program. If both are set the zone level frequency is used. If no frequency is provided the program will run every day at the specified start time. Application at the zone level allows different zones to execute at the same time of day but use varying frequencies. for example: Vege Patch every two days and the Lawn once a week.
The values provided can be:
- numeric, representing how often to run every 2 days for example.
- days of the week; Mon, Tue etc. These currently only support english abreviations.
- Off or any unsupported text to stop the zone being run.
For Australians you can select to water on specific days of the week to support water restriction rules.
Defining a Dropdown helper to use with the run_freq attribute, for example:
options:
- off
- 1
- 2
- 3
- Wed, Sat
- Mon, Wed, Fri
- Mon, Tue, Wed, Thu, Fri, Sat, SunWhen a program or zone is triggered manually the following rules are applied:
If the Program is disabled it can still be initiated manually to run all enabled zones.
- If the Program is disabled and the Zone is enabled the zone will run if manually started,
- If the Program is disabled and the Zone is disabled the zone will not run,
If the Zone is disabled it will not run until it is enabled.
- the zone is disabled, or
- the zone frequency is 'Off'
These sensors will be defaulted:
- Water Adjustment will default to 1
- Rain sensor will default to off
The ECO feature allows multiple short watering cycles to be configure for a zone in the program to minimise run off and wastage. Setting the optional configuration of the Wait, Repeat attributes of a zone will enable the feature. Perfect for pots and can reduce water used by 50%.
- wait sets the length of time to wait between watering cycles
- repeat defines the number of watering cycles to run
You can optionally define a pump/master soleniod to turn on concurrently with the zone. The pump class then monitors the zones that require it and will remain active during zone transitions. The pump will shut off a few seconds after a zone has completed alowing a smooth transition between zones. The pump is only started and monitored when water in started by the custom control.
You can define a binary sensor that monitors the availability of the water source. For example if your well can run low on water this will have the following impact:
- If a zone is running the zone will be stopped.
- A zone will not start until the sensor inticated (on) that water is available.
You can optionally configure zones to run concurrently. Create a switch group, group helper. This feature allows you to group switches together to operate as a single switch.
You can use this 'new' switch to define a zone in the program.
If you have binary binary sensor that indicates the status of the watering system hardware, you can use this to prevent this system from initiating watering until the system is active.
For example I use an ESPHome implementation to control the hardware it exposes a status sensor, should the controller lose power or connectivity to Wi-Fi the custom control will not initiate the watering. There is also be a visual indication on the custom card of the status of the controller.
Additionaly, zone switches that are not in a known (on, off) state will not be executed, and a warning message will be logged.
As an alternative to the rain sensor you can use the watering adjustment feature. With this feature the integrator is responsible to provide a multiplier value using a input_number or sensor component. I imagine that this would be based on weather data or a moisture sensor.
If a program or zone is run manually the adjustment is ignored and executed with the adjuster value of 1.
See the https://github.com/petergridge/openweathermaphistory for a companion custom sensor that may be useful.
Setting water_adjustment attribute allows a factor to be applied to the watering time.
- If the factor is 0 no watering will occur
- If the factor is 0.5 watering will run for only half (50%) the configured watering time/volume. Wait and repeat attributes are unaffected.
- A factor of 1.1 could also be used to apply 110% of the water defined watering.
- If you want to water in seconds apply a factor of .0167 will be an approximate solution
Turn off running programs when a new program is started, this is the default.
Note Change this on all program configurations to get consistent behaviour.
With interlock enabled:
- If Program 1 and Program 2 have the same start time neither program will run and a warning is logged.
- If Program 2 starts while Program 1 is running Program 1 will be terminated and Program 2 will run, a warning will be logged.
With interlock disabled:
- If Program 1 and 2 overlap both programs will continue to run.
- If a running zone is started by the second program a warning is logged.
The program_turned_on event provides the following:
- scheduled: false indicates the program was run manually
event_type: irrigation_event
data:
action: program_turned_on
device_id: switch.test
scheduled: true
program: test
The program_turned_off event provides the following:
- completed: true indicates the program was not teminated manually
event_type: irrigation_event
data:
action: program_turned_off
device_id: switch.test
completed: true
program: test
The zone_turned_on event provides this information:
- scheduled: false indicates the zone was run manually
event_type: irrigation_event
data:
action: zone_turned_on
device_id: switch.test
scheduled: true
zone: dummy_3
pump: null
runtime: 59
water: 1
wait: 0
repeat: 1
The zone_turned_off event provides this information:
- latency: true indicates that the zone could not be confirmed as off
- state: the state of the switch when the event was raised
event_type: irrigation_event
data:
action: zone_turned_off
device_id: switch.dummy_3
zone: dummy_3
latency: false
state: "off"
The zone_became_unavailable event provides this information:
