Hi,

There is an error coming from AW, I assume this is probably because your account has not yet been fully setup for smart meter readings. Can you login to their website to see if you can see them?

You may need to wait 24-48 hours if you have only just created your account.

I can indeed see the data on AW website. I've had the website account for many years but have only viewed smart meter data for the first time tonight and had to click a button confirming I wanted to see hourly data. I've never clicked that before.

I shall look at it again tomorrow and report back. Thank you.

Jon

That might be all that was needed :)

I will make a PR to update the docs to mention some of these things. As I don't have an account in this 'state' I can't validate exactly what the replies are.

I have similar issue, although I have been using this integration since before it was part of core. Debug log shows.
