list_regionsThe 14 Agile regions (GSP groups), each with well-known places in it - to place a home by its town. The regions are the local electricity networks' areas, not counties, so some places surprise (Milton Keynes and Coventry are in the East Midlands, Croydon in South East England, Y…
list_tariffsThe time-of-use and standard tariffs from Octopus, EDF and E.ON Next that the `tariff` parameter accepts – or, with `direction=export`, their export tariffs (for get_prices and `export`), each saying which homes can have it.
get_pricesHalf-hourly prices for a region from midnight today, up to five days (`days`) - Renewably's own format, and the one to use unless your software was built for Octopus's API (then /unit-rates). On Agile (the default), Agile Outgoing, FreePhase Dynamic and Shape Shifters: Agile, ea…
find_cheapest_windowThe cheapest (or lowest-carbon) run of `duration_hours` starting from the next half hour and finishing by the next `finish_by` – when to set a washing machine or dishwasher's delay timer.
plan_ev_chargingThe cheapest or greenest half hours to charge an electric car by a ready-by time up to four days ahead.
get_heat_pump_timesFor a typical weekday and weekend day at this time of year (on a fixed-window or flat tariff, today's rates): the cheapest time to reheat hot water (and the cheapest ready by 07:00), and the cost of each kWh of heat by hour – price divided by a generic air-source heat pump's eff…
get_home_battery_timesFor a typical weekday and weekend day at this time of year (on a fixed-window or flat tariff, today's rates): the cheapest charge slot to fill a home battery before the 16:00 peak, an optional afternoon top-up, and what it saves a home using `usage` kWh a year – the battery runs…
plan_home_batteryA home battery's plan from the half hour under way to the end of tomorrow, on the tariff's real prices (Agile's, and Agile Outgoing's, estimated beyond what Octopus has published), half hour by half hour: charge from the grid, hold, run the house (self-use), export, or send the…
plan_homeA home's past year on every tariff in list_tariffs and at Ofgem's price cap – and what switching tariff, an electric car, a heat pump, solar panels or a battery would save, each added to everything before it (tariff, car, heating, solar, battery). Each of car, heating, solar and…
get_flexibility_eventsWhen the grid operator, NESO, is asking homes in a region to use less electricity (often the evening peak) or more (often in Scotland, when there's more wind than the grid can carry south), through its Demand Flexibility Service: live events from now to the end of tomorrow, usua…
