We have an electricity tariff that changes price every half hour. This is obviously a stupid distraction, a useful money-saving measure (I’ve saved about a third of my electricity costs over the last year) and a little taste of the future. Alongside that, it is a deep temptation to organise my life around this once it is there.

This is not my first go at making Octopus prices useful. Last year I wrote Octopus Agile Prices For Linux, which became Agile Rates, a GNOME app for smart tariff rates, cheap-time finding and usage history. Agile Prices is the smaller Android and Wear OS version. You choose your UK electricity region, it finds the current Octopus Agile import tariff and caches the upcoming half-hour rates. There is no account API key, usage history, export tariff support, Go support, Intelligent Go support, spend analysis, widget, notification system or attempt to become an energy management platform in miniature.
