- Sewage discharge status from Thames Water API
- WE ARE NOT A CLUB
- This is very much a work-in-progress, I'll be refining/adding things every now and then, such as weather details, discharge details etc Jon
08JAN25 - Christmas mode now automatic between 1 Dec to 1 Jan inclusive, then from 2 Jan to end of Feb optional snow, which remembers whether you've toggled it on or off.
25DEC25 - Added Christmas mode! Why didn't I think of that earlier in the month?! It'll be available during December from now on.
08OCT25 - Cleaned up weather forecast, putting it behind a show/hide toggle, also fixing issue with daily vs hourly differences by aggregating rainfall. Also caching for 15 mins rather than requesting every time, to avoiding exceeding Met Office limits.
05OCT25 - Signed up Met Office account and used that to retrieve daily forecast in tiles and hourly forecasts in scroller. Added blatant self-promotion for upcoming gig in the header, because my site my rules.
04OCT25 - Fixed issue with charts not showing enough history; registered domain name and configured DNS/subdomain; expanded notes section.
