Just came here to open exactly the same issue. For me it started yesterday evening around 17:40. This night around 4 it was working again until 4:22. Since then no weather available.

2023-11-03 08:18:40.081 DEBUG (MainThread) [custom_components.meteoswiss] Finished fetching meteoswiss data in 0.086 seconds (success: False)

Looks like an issue while fetching data from meteoswiss.

[thor1872]

I just checked now that i got some sleep and your right looking at the history it started at 17:44 yesterday for me and got worse and worse, so maybe it's meteo swiss itself the problem and not the integration. And me updating yesterday was most likely just a coincidence.

Edit: i just re enabled the integration 20min ago and no issue for now.

[vistalba]

For me it still doesn‘t work at all. Same issue since 04:22 this night. Any Idea how to troubleshoot whats going wrong while fetching the data?

[thor1872]

Weird it's doing fine for 2h now. Maybe try reinstalling the integration completely to see if it fix it.

Already tried this today morning without luck :(

Then i am out of idea, the only thing i did was remove the integration at 5am before going to sleep and then put it back up at 15h and now it work. Maybe the station that you want to use or meteo swiss is still having issue, i really don't know sadly.

[thor1872]

welp after ~3h without issue, it's doing it again.

[vistalba]

For me it still doesn't work. Just tried with a complete new install and config. No luck. So I tried to investigate whats wrong.

When I take a look to the code, I see various URLs. Some of them look like they do not exist anymore...

MS_BASE_URL = "https://www.meteosuisse.admin.ch"
JSON_FORECAST_URL = "https://app-prod-ws.meteoswiss-app.ch/v1/forecast?plz={}00&graph=false&warning=true"
MS_SEARCH_URL = "https://www.meteosuisse.admin.ch/home/actualite/infos.html?ort={}&pageIndex=0&tab=search_tab"
CURRENT_CONDITION_URL = (
    "https://data.geo.admin.ch/ch.meteoschweiz.messwerte-aktuell/VQHA80.csv"
)
STATION_URL = "https://data.geo.admin.ch/ch.meteoschweiz.messnetz-automatisch/ch.meteoschweiz.messnetz-automatisch_fr.csv"
STATION_TYPE_PRECIPITATION = "Précipitation"
STATION_TYPE_WEATHER = "Station météo"

MS_24FORECAST_URL = (
    "https://www.meteosuisse.admin.ch/product/output/forecast-chart/{}/fr/{}00.json"
)
MS_24FORECAST_REF = "https://www.meteosuisse.admin.ch//content/meteoswiss/fr/home.mobile.meteo-products--overview.html"

So I'm curious if we are really only two that running into issues or if there are several more users affected. Btw: Which station are you using? I use "KOP".

[beatdoebeli]

Same problem here. Just switched to the Rudd-O fork of Meteoswiss this morning, so I can't tell since when the problem exists.

Did you already try to switch back? Does it help?

[badewanne1234]

Same here, it started around 6PM on 2-Nov, see screenshot. I did update to the latest version of the meteo integration today, but no luck..

[vistalba]

Same picture for me as @badewanne1234 posted. Sometimes it comes back for a few seconds then it stops working again.

I use PUY and like you say some link aren't working, MS_24FORECAST_URL and MS_24FORECAST_REF say "Page not found" so that might be a problem, but it's still weird that sometime it work and sometime not.

I just tried using the old weather.py file here

but the issue still happen, so it looks like it isn't the change made in the last update that's the problem. And the comment from badewanne1234 make me think that too.

So in the end i still don't know what's the issue. And i am not a dev so i can't really help much sadly.

Edit: i just updated Home assistant core from 2023.11.0 to 2023.11.1 and no change. And right now i am trying a update interval of 10min instead of 1min to see if maybe that change something, who know maybe meteo swiss don't like getting asked every minute but i doubt that it will change anything.

Edit2: changing to 10min interval didn't change anything, still getting the error after 8h...

[gzxto1]

welp after ~3h without issue, it's doing it again.

Have exactly the same issue...

[fredmatix]

Same issue here. The main reason I was switching from the official meteo-swiss app to this fork (meteoswiss) was the connection issues. I do have even bigger gaps in the stats:

Core 2023.11.1 Supervisor 2023.10.1 Operating System 11.1 Frontend 20231030.1

HACS: Integrations Version: 1.33.0 Frontend Version: 20220906112053

Meteo Swiss Version: latest

[sereros]

I‘m facing the same issue. It started at about on the 03.11.

[kess78]

Same here... so happy to see that I'm not alone ;-)

[thegoija]

for some reason, get_forecast in hamsclientfork uses a xhtml header to receive json data. I have changed

_HEADERS = {
    "Accept": "text/html,application/xhtml+xml,application/xml;"
    "q=0.9,image/webp,*/*;q=0.8",
    "Accept-Encoding": "gzip, deflate, sdch",
    "User-Agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML"
    ", like Gecko) Chrome/1337 Safari/537.36",
}

to

_HEADERS = {
    "Accept": "text/html,application/json",
    "Accept-Encoding": "gzip, deflate, sdch",
    "User-Agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML"
    ", like Gecko) Chrome/1337 Safari/537.36",
}

directly in /usr/local/lib/python3.11/site-packages/hamsclientfork/client.py. Running now without issues for 24 hours.

[JamborJan]

Thanks for the effort @thegoija . Apparently it didn't change anything in my case. I'm still seeing the "Expecting value: line 1 column 1 (char 0)" error and no date is getting fetched. The last status change was 13 hours ago. In my case the issue started after updating to HA 2023.11. Also the update to 2023.11.1 didn't change anything. Like others replied already in this issues.

[vistalba]

Does not work for me :( Still the same issues. i guess it is not HA Version releated. The issue started for me on 3. November at around 17:44.

[JamborJan]

For me it's the same date where the issue started but it is also the same date I updated HA. I'll roll back HA later today and test that.

[vistalba]

For me I still was on 2023.10 when it stopped working. So I do not have a lot of hope that a rollback will help.

[elduca]

Same issue here after updating the integration

[sebcou21]

Same behavior observerd on my side with issue starting on 02.11 around 17:40. I was still on 2023.10 at the time as well, so rollback will probably be useless.

[TimMayle]

I'm guessing the issue might be on meteoswiss API side. As we don't request the data of the same meteo station, we might could experience a different behaviour on our sides.

I couldn't find detailed information and status for this service. Best page found yet is this one: https://www.meteoswiss.admin.ch/weather/measurement-systems/data-management.html They might have changed their API without us knowing.

With more free time, I would create an account to test the API. Evidences yet are:

• not linked to HA version
• started on Nov 3rd
• not seem neither to be linked to recent module update
• same behaviour with a fresh module install

PS: As Frenck suggested, no need to add comments such as "same here". Just subscribe or follow the issue.

[hb9eue]

I wonder if this could be caused by some rate limiting on the API side?

[vistalba]

I wonder if this could be caused by some rate limiting on the API side?

Unlikely as for me the Meteo Swiss app, simple API Calls to the same endpoints and also download of the CSV File with the stations does work when I do this manually.

[fredmatix]

For me since 8. November 16:00 the issue disappeared: Anyone else now having stable incoming data?

[danielhad]

Hi, yes. It seems to be stable now. At least in my system.

[gzxto1]

the same for me.... :-)

[thor1872]

same here, working fine for two day now, so it was most likely a issue with meteo swiss itself.

[Rudd-O]

I'm thinking this is an issue with MS itself too. Enabling debug logging can show what the error condition was.
