The openuv integration displays UV and Ozone data from openuv.io.

Generating an API Key

To generate an API key, simply log in to the OpenUV website.

Beginning February 1, 2019, the "Limited" plan (which is what new users are given by default) is limited to 50 API requests per day. Because different API plans and locations will have different requirements, the openuv component does not automatically query the API for new data after it initially loads. To request new data, the update_data service may be used.

Each use of the update_data service will consume 1 or 2 API calls, depending on which monitored conditions are configured.

If the OpenUV integration is configured through the Home Assistant UI (via the Configuration >> Integrations panel), each service call will consume 2 API calls from the daily quota.

If the OpenUV integration is configured via configuration.yaml, service calls will consume 2 API calls if monitored_conditions contains both uv_protection_window and any other condition; any other scenarios will only consume 1 API call.

Ensure that you understand these specifications when calling the update_data service.

Configuration

To retrieve data from OpenUV, add the following to your configuration.yaml file:

openuv:
  api_key: YOUR_OPENUV_API_KEY

{% configuration %} api_key: description: The OpenUV API key. required: true type: string binary_sensors: description: The binary sensor-related configuration options. required: false type: map keys: monitored_conditions: description: The conditions to create sensors from. required: false type: list default: all keys: uv_protection_window: description: Displays if UV protection (sunscreen, etc.) is recommended at the current date and time. sensors: description: The sensor-related configuration options. required: false type: map keys: monitored_conditions: description: The conditions to create sensors from. required: false type: list default: all keys: current_ozone_level: description: The current ozone level in du (Dobson Units). current_uv_index: description: The current UV index. current_uv_level: description: "The level of current UV index, which is calculated based on UV Index Levels & Colors." max_uv_index: description: The maximum UV index that will be encountered that day (at solar noon). safe_exposure_time_type_1: description: The approximate exposure time for skin type I. safe_exposure_time_type_2: description: The approximate exposure time for skin type II. safe_exposure_time_type_3: description: The approximate exposure time for skin type III. safe_exposure_time_type_4: description: The approximate exposure time for skin type IV. safe_exposure_time_type_5: description: The approximate exposure time for skin type V. safe_exposure_time_type_6: description: The approximate exposure time for skin type VI. {% endconfiguration %}

The approximate number of minutes of a particular skin type can be exposed to the sun before burning/tanning starts is based on the Fitzpatrick scale.

Full Configuration Example

To configure additional functionality, add configuration options beneath a binary_sensor and/or sensor key within the openuv section of the configuration.yaml file as below:

openuv:
  api_key: YOUR_OPENUV_API_KEY
  binary_sensors:
    monitored_conditions:
      - uv_protection_window
  sensors:
    monitored_conditions:
      - current_ozone_level
      - current_uv_index
      - current_uv_level
      - max_uv_index
      - safe_exposure_time_type_1
      - safe_exposure_time_type_2
      - safe_exposure_time_type_3
      - safe_exposure_time_type_4
      - safe_exposure_time_type_5
      - safe_exposure_time_type_6

The above guidelines constitute estimates and are intended to help informed decision making. They should not replace analysis, advice or diagnosis from a trained medical professional.

openuv.update_data

Perform an on-demand update of OpenUV data.

Examples of Updating Data

One method to retrieve data every 30 minutes and still leave plenty of API key usage is to only retrieve data during the daytime:

automation:
  - alias: Update OpenUV every 30 minutes during the daytime
    trigger:
      platform: time_pattern
      minutes: '/30'
    condition:
      condition: and
      conditions:
        - condition: sun
          after: sunrise
        - condition: sun
          before: sunset
    action:
      service: openuv.update_data

Another method (useful when monitoring locations other than the HASS latitude and longitude, in locations where there is a large amount of sunlight per day, etc.) might be to simply query the API less often:

automation:
  - alias: Update OpenUV every hour (24 of 50 calls per day)
    trigger:
      platform: time_pattern
      minutes: '/60'
    action:
      service: openuv.update_data
