Greetings,
There is currently an issue with the UK Met Office API which can (but doesn't always) result in a failure to retrieve a weather forecast. I have raised a support ticket with the Met Office support team and I am awaiting a reply. Other users of this data have reported the same issue, so it's not just affecting Compu-Tron x3000. Once I receive an update, I will post again here with the details.
Regards
