The changelog on github mentions

UI: Add Weather Widget in Live-View
[…]

  • Add Weather Widget
    • Added new Weather Widget in Live View below the Energy Monitor
    • Displays current weather, 6-hour forecast, and daily forecast for the next 6 days
    • Shows temperature, general weather condition, and sun hours
    • Weather data is retrieved from the Edge using coordinates stored in Meta configuration
    • Forecasts are retrieved in quarter-hourly, hourly, and daily resolution for the next 7 days
    • Linear prediction model adapted to handle the new weather data format
    • Forecasts are cached on the Edge and the UI fetches only the data it currently needs

l have added the coordinates in the _meta component, and also the Weather Open-Meteo widget is enabled. Still I do not see the UI weather widget. What am I missing?

Hi @sjjh,

try again with latest develop Branch. There were still some parts missing in the FEMS Backport.

Regards,
Stefan

@stefan.feilmeier do i understand correctly, that the latest Backports removed Grid Surplus for EVSE and P40 ?

@Sn0w3y No, that’s not true. Why do you think so?

In commit 23db377819, the AUTOMATIC_SWITCHING mode was removed from the PhaseSwitching enum (it only has DISABLE, FORCE_SINGLE_PHASE, FORCE_THREE_PHASE now).

How is the P40 supposed to automatically switch between single-phase and three-phase charging based on available grid surplus power?

With only the forced modes available, it seems like phase-switching would need to be triggered externally (via UI or another Controller), rather than automatically responding to surplus power changes. Is that the intended behavior, or am I missing something in how the new implementation works?

Thanks for clarifying!

For now this is the intended behaviour. This is the first release that actually supports phase-switching (I use it at home with P30 + S10; tested in lab with P40; will implement with HardyBarth very soon) and we use it to gain experience.

For future we plan to have again a possibility to choose between AUTOMATIC, FORCE_SINGLE and FORCE_THREE.

it seems like phase-switching would need to be triggered externally (via UI or another Controller)

Yes. That is a valid use-case for many systems.

By the way there are more use-cases for automatic switching than just "PV-Surplus”, e.g. “Switch to THREE_PHASE when in FORCE_CHARGE mode, e.g. when charging in cheapest hour)”. Also there are many vehicles that do not support phase-switching and will stop charging completely. This we will have to take care of carefully.
