automation examples to change binary_sensor

[domoticauser]

I made 2 helpers, sensor.bewatering_aanpassing and binary_sensor.bewatering_regen
When i change these in the developers section they do change, and it works.

Only i can find a way to make an automation to change these values?
Maybe there a some automation examples?

Hi, there are examples here:

input_boolean:
rain:
icon: mdi:weather-pouring
name: rain
well:
icon: mdi:water-well-outline
name: well
controller:
icon: mdi:alarm-panel
name: controller

template:

• binary_sensor:
  • name: Rain
    state: "{{ is_state('input_boolean.rain','on') }}"
    icon: mdi:weather-pouring
  • name: Well
    state: "{{ is_state('input_boolean.well','on') }}"
    icon: mdi:water-well-outline
  • name: Controller
    state: "{{ is_state('input_boolean.controller','on') }}"
    icon: mdi:alarm-panel
• sensor:
  • name: Adjustment
    state: "{{ states('input_number.adjustment') }}"
    icon: mdi:knob
• sensor:
  • name: Flow Sensor
    state: "{{ states('input_number.flow_sensor') }}"
    icon: mdi:waves-arrow-right

input_number:
flow_sensor:
name: 'Flow Sensor'
min: 0
max: 20
step: 1
icon: mdi:waves-arrow-right
unit_of_measurement: 'L/min'
adjustment:
min: 0
max: 2
step: .1
icon: mdi:knob

Changing the irrigation duration is not as easy as expected. The add-on requires sensor.bewatering_aanpassing, but I would like to adjust this value based on rain or high temperatures. After a lot of reading and testing, it seems that sensor.bewatering_aanpassing is read-only in Home Assistant.

For binary_sensor.bewatering_regen, I would like to use Buienradar (Dutch weather service for irrigation). When rain is detected, it should be set to "rain," preventing irrigation.

Is there a reason not to use input_number.bewatering_aanpassing instead? And for rain detection, would a switch be a better option?

Apart from this, the setup is quite simple, but I can't figure this part out.

Hi,

The rain sensor function is a yes/no feature so the most appropriate sensor model is a boolean. The above examples demonstrate how you can translate input types to sensor types if you want to use this model.

You look at using the OpenWeatherMapHistory component to adjust the watering dynamically based on the amount of rain.

Something is not working or I don't understand it.
The sensor.bewatering_aanpassing (runtime adjustment sensor) is in the irrigation addon.
To adjust the adjustment, I want to create an automation to modify it.
I want to use data from a rain radar, moisture sensor and temperature to influence the watering time. It seems that the runtime adjustment cannot be modified in an automation.
The binary rain sensor is working!

Hi,

You need to create a sensor, check out the template sensor above 'adjustment'. the example below will create the ability to manually apply the adjustment. However if you replace the "{{ states('input_number.adjustment') }}" with any jiinja2 script. The state value needs to be numeric 0 will stop watering, 1 will water 100% 1.1 will water an additional 10%...

template:
  sensor:
    name: Adjustment
    state: "{{ states('input_number.adjustment') }}"
    icon: mdi:knob

input_number:
  adjustment:
    min: 0
    max: 2
    step: .1
    icon: mdi:knob

Hello,

Thanks for your help. But I’m not getting any further with it. Maybe I’m misunderstanding something.
The screenshot below shows sensor.bewatering_aanpassing, which works fine. If I change the value manually, the watering duration is shortened or extended accordingly.

But what I want is to be able to change this value through an automation. So for example, if the temperature is above 25 degrees, I want the value of sensor.bewatering_aanpassing to be set to 1.5.

Hi, this is an example of a sensor that calculates based on temperature:

template:
  - sensor:
    - name: temp_adjustment
      state: >
              {% set my_test_json = {
              "temperature": 25,
              "unit": "°C"
              } %}
              {% set temp = (my_test_json.temperature) -%}
              {% if temp < 10 -%}
              0
              {% elif temp < 20 -%}
              1
              {% else -%}
              1.1
              {% endif -%}

You can replace:

              {% set my_test_json = {
              "temperature": 25,
              "unit": "°C"
              } %}
              {% set temp = (my_test_json.temperature) -%}

with your own temperature sensor details.

then you can use this sensor as the runtime adjustment:

YES!! It works. I learned a lot of this.

Thanks for your support!
