Dynamic Tariff UI: Add support for shorter time slots (< 1h) #12915

The UI currently assumes that prices only change every hour. Cheap grid charging, cost calculations and afaik also the planning algorithm are not limited to fixed time intervals. What would your expectation for the UI be? Half hour slots? Avg. values? Is it always 30m intervals at octopus? |

Thanks for confirming that the grid charging + cost calculations + planning algorithm are not bound by a fixed 1 hour time interval. That's great news. With regards to Octopus energy, I can confirm that at least in the U.K. , the shortest tariff interval is indeed a minimum of 30mins. I have come across this post, that implies other energy supplier smart tariffs might be also worked on a very short 15minutes intervals: In terms of U.I. , I would imagine that if possible, it would be fantastic to actually derive the interval duration from the API request (So if there are any records for change of tariff at time For example , from octopus I get a total of 24hours ahead (+ 24hours in the past, no longer relevant), 30minutes intervals indicated by some I quite like the way, evcc presents those stuitable slots (in green) when the cost per Kwh is below the targetted price limit. In my case that would be around 48 records (24hours ahead in 30minutes intervals) I don't know if adapting a U.I to do such is at all possible. |

Yes, this sounds like a good compromise where users with hourly prices (every tariff in Germany I know of) don't get unnecessary detail and users of finer tariffs (30m, 15m) get more bars depending on the API response. This is not a trivial change. But since the underlying logic should work as expected, right now, I'd see this as a lower priority feature. But we should definitely do this. |

Planner accepts full hours only, too. |

Perspektivisch müssten wir wohl auf die 15 Minuten Basistakt des Strommarkts kommen. |
I would like to clarify how a smart grid tariff like the one from
octopusenergyAGILE-23-12-06, which changes every 30minutes, is handled by EVCC ?I can see that the U.I only presents the cost of the Kwh in a full hourly slot, with the cost for this hour slot based on the cost at the beginning of the hour only (no averaging with the second half of the hour).
Is evcc correctly handling tariffs that have Kwh costs changing within a one-hour period ?
evcc tariffAPI request command , forAGILE-23-12-06correcly shows those half-hourly costs changing but I am not certain as to whether evcc works in the backgground "honouring" those intra-hourly varying costs ?https://imgur.com/a/yxKRL3v
