After recent 2025.4.1 upgrade Met Office integration no longer working

I am getting “entity not available” and also when I go to the login page my username and password is no longer valid. It also shows a met office premium page.
Have they changed the free tiers?
Is this in issue with the integration?

Which Met Office service are you using?

The old one, Datapoint, is being phased out and replaced by Datahub. You need a different account.

I don’t think the HA integration works with Datahub yet. However there is an excellent set of templates and sensors to access the new API here:

Pretty sure I have registered for Datahub and that is what I was using to get data via the API key

I made no changes and it seems to all be working again now.,…

For me the service has been dropping in and out since the start of April.

The Met Office Datapoint service is ending in September this year and is currently unsupported.

If you’re using the “official” HA integration, Datapoint is the service you are accessing, and you need to migrate soon.

I am using the official integration it seems.
