New custom component: France weather alerts from Météo France

oncleben31 · June 11, 2018, 12:49pm

I’m working on getting France weather alerts in home-assistant.
Last days we had a lot of issue in my area with thunderstorm, flood and landslides. So I’m really motivated to accelerate this projects.

I’m writting here to have some feedback. Are you intterrested? Are you using other weather sources?
According to your answers I will do a “Quick&Dirty” implementation or make it mature enough to be shared with the community.

For information I’ve already developped the python API: Vigilancemeteo on Github
And I working on implementing it as a Sensor.

Edit: the PR is merged in 0.95 release and the feature is available to all of HA users in meteo_france integration.

Results of the first sprint for implementation.

Next sprint:

Add forecast update date and time
Add URL for geting more information
Bulletin synthesis converted to HTML format.

Hello !

I’m working on a Meteo-france component
It was released on the last version with multiple sensor for monitored conditions (temperature, rain forecast, etc)
I also submitted a PR for the weather card which is awaiting approval

I think the alerts could be a great addition.
This could be added as a new monitored_conditions and would use the postal_code configuration to guess the department

Hello,

I’ve seen your component and was planing to reach you. You was faster than me
It’s a good idea. But I wondering if we should no use other existing component (compare to ‘weather’) as it’s seems to not be standard to include weather alerts in the other ‘weather’ platforms.

I’m thinking about geo-location component.
Let me 1 or 2 weeks as I have very few time spend on home-assistant. And we can discuss on the best way to integrate with your platform.

Hi everybody !

Thank you for your work, it arrives at a good time with the end of free api of Wunderground !!

I’ve got 2 request for you :

Where can I find the complet list of human-readable text summary of the current conditions ?
Do you plan to add the forecasted weather to this component ?

Thank you really for your work !!!

Hi,
This looks good and I’ll give it a try.
It is a shame that humidity was not included.
I am using weather data to calculate moisture in the air and control my mechanical ventilation ( vmc) to pullin air dry air to my holiday home.
I have not yet implemented it as I am not yet confident on the external humidity data.

Hello, I would love to use your sensor for it’s french human-readable text summary but unfortunately my foreign city is not available. Could it be possible to add a european city with it own postal code delivered by météo france (ex: previsions-meteo-monde/londres/03772) 03772 for london.
It would be a great feature for French People living abroad.

Thanks.

Hi,

I have a PR in progress which haven’t received review for a long time now.
It includes the ability to add sensors for any cities covered by meteo-france and the weather component.

I was quite busy and didn’t make much effort to get it approved but I will try to get back at it
I will keep this post updated

Romquenin · January 10, 2019, 3:12pm

Thanks victorcerutti, can’t wait to use your sensors.

oncleben31 · April 26, 2019, 11:33am

Updates on the project:
We agrees with @victorcerutti to integrate weather alerts in the meteo france component. We have worked together to integrate it. It’s now stable.
A PR is in progress

oncleben31 · May 19, 2019, 6:15am

The PR has not been reviewed yet. If you want give a try you can install it as a custom component.

To do that, first copy this folder in your custom_components folder and then add the following configuration

meteo_france_custom:
  - city: !secret city
    monitored_conditions:
        - rain_chance
        - freeze_chance
        - thunder_chance
        - snow_chance
        - weather
        - next_rain
        - wind_speed
        - temperature
        - uv
        - weather_alert

Don’t hesitate to share your feedbacks

oncleben31 · June 20, 2019, 9:32am

PR merged. So will be available with meteo_france integration in next release (0.95)

I get a nice error at startup :

It seems that a dependancy does not work with a fresh hassbian install.

oncleben31 · June 27, 2019, 10:33am

Can you sahre more on your configuration? Is it an error with the custom component?
Can you try again with the 0.95 release?

doune · June 27, 2019, 12:12pm

This error was solved with a specific pip install.
It was with the custom component. I’ve to try with the 0.95 version.

Hello, I have exactly the same problem with version 0.95.4 on Full new install HASSBIAN.

Can you teach me?

oncleben31 · July 15, 2019, 8:04pm

Strange, it seems some python library are missing in your install.
Can you try the workaround inthis post

ninjax95 · July 16, 2019, 6:24pm

Thanks, it’s works.

sudo apt-get install libxslt-dev

doune · July 24, 2019, 9:47am

it seems not working anymore :

2019-07-24 10:34:48 ERROR (SyncWorker_17) [homeassistant.components.meteo_france] HTTPConnectionPool(host='www.vigimeteo.com', port=80): Max retries exceeded with url: /PREV/V/ (Caused by ConnectTimeoutError(<urllib3.connection.HTTPConnection object at 0x65fcde50>, 'Connection to www.vigimeteo.com timed out. (connect timeout=10)'))

oncleben31 · July 24, 2019, 10:28am

It seems more related to a ponctual server issue. I still receive the weather alert currently.
Can you confirm it still the case
Is there other user with the same error message ?
