Automation of OpenUV in HomeAssistant

What started as a weekend experiment now that the sun is out turned into a bit of a headache.

After I checked my OpenUV automations from last year I realized that something was not working as intended.

First thing I noticed was that the UV Index card installed from HACS was not displaying any info, now I've discovered in the past that there are a certain amount of calls for the OpenUV api calls to get the info you want.

 Fixed Duplicate Sensors 

While poking around I've realized I've turned off OpenUV integration and created a new one.

This lead to some duplicated sensors, but this was a quick fix. Once I turned on the original integration my guess is that HomeAssistant know that the other integration is the same and removes it completely

Some entities needed to have their .yaml code revied and just remove the _2 from those entities and all was good.

sensor.openuv_current_uv_index_2
change to 
sensor.openuv_current_uv_index

Limiting the Sensors to Avoid API Abuse

Each monitored condition = one API call. So I edited my configuration to only keep what I actually needed.

If math is correct we should not exceed the 50 calls per day, tomorrow I'll need to check after work to see if its all working as intended.

 Card for Dashboard 

Addressing the card in the dashboard I've changed the code around a little to expose uv index at the moment, max uv for the day and skin types exposure.

type: vertical-stack
cards:
  - type: custom:uv-index-card
    entity: sensor.openuv_current_uv_index
  - type: entities
    title: Safe Exposure Times
    show_header_toggle: false
    entities:
      - entity: sensor.openuv_max_uv_index
        name: Max UV index
      - entity: sensor.openuv_skin_type_1_safe_exposure_time
        name: Skin type 1
      - entity: sensor.openuv_skin_type_2_safe_exposure_time
        name: Skin type 2
      - entity: sensor.openuv_skin_type_3_safe_exposure_time
        name: Skin type 3
      - entity: sensor.openuv_skin_type_4_safe_exposure_time
        name: Skin type 4
      - entity: sensor.openuv_skin_type_5_safe_exposure_time
        name: Skin type 5
      - entity: sensor.openuv_skin_type_6_safe_exposure_time
        name: Skin type 6

Automations

I've figured that the Automations from last year were gone so time to dig in.

I've realized many notifications can be annoying for the family so I've broken it down in two notifications for now per day. One is to start at 10am and later another if the max index changes and the user needs an heads up.
