[OpenTRV-interest] Met data (was: Boiler controller (Was: The shop is open!))

[Niall Robinson]

I'll have a dig about in the new year and see what I can find. The data will definitely exist, I suspect it'll be free to use for non-profit stuff.

Have you guys thought about having a https://slack.com/ <https://slack.com/> channel to save pinging emails back and forwards - I can set one up if you like and see if people like it?

The Met Office's Historical Station Observations http://www.metoffice.gov.uk/datapoint/product/historical-station-obs offer mean daily max and minimum temperatures but I'm looking for better granularity: ideally average temperatures for each hour of the day.

So I'd like to be able to say "what if we all go to bed (or at least turn the heating down) an hour earlier: how much money would it save?". For that I need to know what temperatures are at different times of the day, not just averages (or max and min) for a day.
