The problem

The NetAtmo integration is periodically unavailable on all sensors, while the Netatmo official app anf Homekit integration work fine. There is nothing Netatmo related in the logs. This is what my sensors look like:

I have the same problem. I recharge it and it comes back for a while.

For the past few days the integration has been losing contact with the API. They may have changed the query limit.

The connectivity changed to unavailable at 21:54:25 and back to available at 22:45:25
My weather station has 5 devices and 41 entities.

[cgtobi]

Are you using HA Cloud or your personal dev key?

[EDelsman]

Is there a way to tell? I can't remember. By password manager does not suggest a developer account so I think cloud.

I'm tempted to create a developer account but that won't help you test a possible fix, so I won't for now.

If relevant: I have a weather station, pretty much filled up to the max: 5 temp/hum/co2 devices, a rain sensor and a wind sensor. So 7 devices in total, 63 entities. I also have homekit as a backup (not always reliable and does not support wind/rain), but I don't think that counts because that is local.

[NorbertHD]

I have a HA cloud Abo. No personal dev key..

[Dfb78]

The same thing happens to me

[ashpole]

I moved from log in to personal credentials via dev.netatmo.com and all fixed for me.

[pbranly]

Hi could you describe what you have done ?
Thanks
Phil

[ashpole]

Go into and delete your device(s) in the Netatmo integration, don’t delete the integration but it will disappear once all devices are gone.

1. On dev.netatmo.com, go to “My Apps” → “Create” (or similar “+ new app” button).
2. Give it a name (anything — e.g. “Home Assistant”) and a short description; Netatmo may ask for a company/website field too, anything reasonable works.
3. Once created, it’ll show you a Client ID and Client Secret — that’s what goes into HA.
4. Scopes — make sure read_station is ticked at minimum for the weather station data.

Go back to HA:

1. Go to Settings → Devices & Services → “Application Credentials” (it’s a separate tab/section from the main integrations list, not the “+ Add Integration” button).

2. Add a new credential there: select “Netatmo” as the integration, give it a name (anything), and enter your new Client ID and Client Secret from the dev portal.

3. Then go back and add the Netatmo integration as normal (+ Add Integration → Netatmo) — it should now either use that credential automatically, or if you’ve got more than one credential saved, prompt you to pick which one.

I’m sure that’s complete but shout if you have a problem.

[pbranly]

Fantastic
Thank you very much
It is very clear
Phil

[EDelsman]

As said, Ill hold out on creating a developer account until the fix is done or the release next wednesday to test a fix.

I think many folks would be unhappy if they all need to, and judging from ldebug ogs above it is a polling rate issue.
