Sprinkler smart automation if not raining tomorrow with Meteorologisk institutt integration

raidnet-ms · July 23, 2021, 9:19am

Hello,
I’m trying to configure an automation to turn on garden irrigation if forecast is not rainy and keep automation as simple as possible.

I already found some topic using OpenWeatherMap in the forum but since 2019 I think hassio made lot of improvements that could make the automation more simple using Meteorologisk institutt integration.

I imagine to use a condition like this

condition: state
entity_id: weather.home
state: !rainy
attribute: forecast

But I need to set state as “not” rainy to perform the correct automation.

!rainy is not supposed to work, but would be great

thanks for any suggestion!

Using the NOT condition. It is also configurable via UI.

condition:
  condition: not
  conditions:
    - condition: state
      entity_id: weather.home
      state:
        - rainy
        - pouring

Edit: If you need to make a list for the state of weather.home.

Oh thank you, now I understand better the logic of automations.

What about the attribute? Is it necessary?

condition: not
conditions:
  - condition: state
    entity_id: weather.home
    state: rainy
    attribute: forecast

I don’t think so. Why do you want to include it?

raidnet-ms · July 23, 2021, 9:36am

It is prompted by the UI, I have no clue about what is suited for

ardysusilo · July 23, 2021, 9:39am

You might want to add a list for your condition, such as pouring, lightning-rainy, snowy-rainy.

See my edited post above.

raidnet-ms · July 23, 2021, 9:39am

Regarding the state list, where can I find all the possible states of weather forecast integration?

ardysusilo · July 23, 2021, 9:42am

Should be this Weather Integration.

But I am not so sure.

Edit: Sorry, I did not realize that you want a state forecast. I think you can enable a setting in the integration to get that sensor.

raidnet-ms · July 23, 2021, 9:45am

Well today forecast would be enough considering that it will be cicled everyday.

ardysusilo · July 23, 2021, 9:49am

Using openweathermap, does weather.home entity have a state attribute of forecast?

raidnet-ms · July 23, 2021, 9:52am

I found these as all possible precipitation states:
state: rainy,pouring,lightning-rainy,snowy-rainy,snowy

ardysusilo · July 23, 2021, 9:55am

Okay then you should be able to use that. Because in my Accuweather integration, I do not have it in weather.home entity.

In the Condition UI, you’ll need to pick the attribute from the weather.home.

raidnet-ms · July 23, 2021, 9:56am

I’m not using openweathermap, but the native home assistant weather integration, at least in Europe we got:

Meteorologisk institutt (Met.no) Integration as default integration. Unfortunately there’s no documentation.

Maybe in USA you get a different integration.

And Yes, this integration provides a state attribute of forecast but I would expect to find a number value after it (number of days) considering that it is providing 5 days forecast.

ardysusilo · July 23, 2021, 10:00am

Can you give us the complete state attribute of your weather.home?

Maybe you need a template to extract tomorrow’s forecast.

raidnet-ms · July 23, 2021, 10:03am

As attribute (optional) the UI provides me this list:

temperatue
humidity
pressure
wind bearing
wind speed
attribution (???)
forecast
friendly name

Under attribute i have “for” value. Meant to be days?

condition: not
conditions:
  - condition: state
    entity_id: weather.home
    state: rainy,pouring,lightning-rainy,snowy-rainy,snowy
    attribute: forecast
    for: '1'

~~Unfortnately~~ the UI ~~doesn’t~~ tells me if “for” should be a ~~“1d” value or~~ “01:00:00” hour value and seems to be an offset.

ardysusilo · July 23, 2021, 10:20am

Can you go to Developer Tools —> States (tab) —> Type weather.home?

You’ll find a bunch of state attribute. You can copy and paste it here.

Because as far as I know, the forecast contain not only tomorrow, but also a few days after that.

Mmmm there’s a numeric precipitation value that could be used instead of text condition value?

raidnet-ms · July 23, 2021, 10:29am

condition: state
entity_id: weather.home
state: precipitation =0
attribute: forecast
for: '12:00'

if only would be possible to selet precipitation value from the forecast…

ardysusilo · July 23, 2021, 10:33am

condition:
  - condition: template
    value_template: >-
      {{ state_attr('weather.home', 'forecast')[0].precipitation < 5 }}

Can you try this? The condition will be true if tomorrow’s precipitation is less than 5.

If you go to Developer Tools → Template → Then copy paste {{ state_attr('weather.home', 'forecast')[0].precipitation < 5 }}

What do you see in the result column?

raidnet-ms · July 23, 2021, 10:40am

Got “true”
