Reacted by Geoffrey CoanStill trying to figure out why it says the car is charging. I wonder if its because its a binary sensor?
Or is it a configuration thing? Because I see the

calculate_plan_every 10 minutesAutomated first-pass triage - a maintainer will review before any action is taken. I investigated using the files attached on this ticket (predbat.log, predbat_plan.html, apps.yaml) against current main (v9.3.5).
Classification: bug (priority_medium) - and the main part of this was already fixed in v9.3.0.
What I verified from the attachments
Your log (v8.29.0) shows the signature of the whole report:
car_charging_planned->binary_sensor.go_echarger_222819_carwithcar_charging_planned_response: 'on'-> Predbat reads "car connected" as "charge is planned". That wiring is correct and documented (planned = car connected to the charger), so this is not a misconfiguration.planned [True], charging_now [False] smart [False]- the important one issmart [False]. You never setcar_charging_plan_smartin apps.yaml, so that False is the shipped default of v8.29.0: in your version bothconfig.pyand thefetch.pyread defaultedcar_charging_plan_smarttoFalse. With Smart off, Predbat plans the car in "all low-rate slots in time order", i.e. it fills the charge need starting from the slot it is plugged in, at whatever price that slot has, even when cheaper slots come later. Your log shows exactly that:Car 0 charging plan is: [{'start': 455...}]- a slot starting at the current minute (07:35, rates 187.2-231.4 ore/kWh, the most expensive of the day), and your plan screenshot from 20:00 shows 23 kWh slotted 20:00-22:30 at 109.5 ore/kWh while 33-39 ore/kWh slots sat overnight before the 07:00 ready time.- "Your car is currently charging." in the Plan details comes from the plan, not from your charging sensor. In
output.py(plan-details builder) that sentence is printed when the plan's car charging kWh over the current 5-minute slot (car_charge_slot_kwh(minutes_now, minutes_now + 5)) is greater than zero - i.e. it reports plan intent for the current slot, in present tense. The docstring for the disabled-Smart behaviour now literally describes "the car starts charging in the first low-rate slot after it is plugged in, even when cheaper slots come later" - so the plan and that sentence were both showing intent, while your go-eis_chargingbinary sensor (wired correctly tocar_charging_now) legitimately says the car is not charging. The plan-details text describes the planned battery/car behaviour throughout (the "The battery is currently at X% and is ..." sentence is also plan-derived), so this is a wording/UX weakness rather than the plan being wrong - flagged below for the maintainer. - Dynamic load amplifies the effect: it adds the car's rate to the current slot's load forecast whenever the plan has a car slot there ("Dynamic load adjust sees car 1 charging now slot 1200-1215"), so a plan-intent slot makes the load forecast expect charging that has not started.
- On your "is it because it's a binary sensor?" question - no: binary vs text sensor isn't the cause. The two entities answer different questions:
binary_sensor.go_echarger_222819_car(car connected) ->car_charging_planned= "a charge is wanted",binary_sensor.go_e_charger_is_charging->car_charging_now= "charging at this minute". The plan schedules from planned; the current-state sentence in plan details describes plan intent. Both entities are wired correctly.
Why the plan sometimes showed car charging slots with the car already full
In your 06:30/12:05 log cycles the car sits at SoC 82.0 kWh = charge limit 82.0 kWh, and the plan correctly schedules nothing (attached plan HTML: Car 0.0 kWh total, no car slots). The visible car slots appear in the later cycles where the car had been driven and plugged back in below the limit - and because of the non-smart default, they start at "now" regardless of price.
How to fix it
- Immediate fix at your current version: turn On
switch.predbat_car_charging_plan_smart- Predbat then picks the cheapest slots before the ready time instead of the first slots after plug-in (for your 20:00 example that would be the 33-39 ore/kWh overnight slots before 07:00 instead of 20:00-22:30 at 109.5 ore/kWh). - The shipped default was switched from Off to On in v9.3.0 (commit
9a82b439, PR fix(car): default car_charging_plan_smart to on (#5237) #5251, tracked as Saving session distorts import-side slot selection, causing peak-rate car/battery charging #5237 - where the maintainer named "car_charging_plan_smart: false (default)" as the cause of peak-rate car charging). If you upgrade to v9.3.0+, check the switch afterwards: the persisted Off state from an earlier install may not reset itself to the new default. - Not related to the Huawei inverter named in the environment details - the battery side behaved as planned in the attached plan.
For the maintainer (still true on current main): the plan-details sentence "Your car is currently charging." (
output.pyplan-details builder, derived fromcar_charge_slot_kwh(minutes_now, minutes_now + 5) > 0) reports plan intent in present tense while ignoring thecar_charging_nowsensor when one is configured - exactly what made this hard for the reporter to interpret. When acar_charging_nowsensor exists and reads False, that line could read "your car is planned to charge now" instead, or fall back to "planned car charging" wording. Optional wording polish, no functional fix needed.Related: #5237 (same trigger - non-smart default causing peak-rate car charging, fixed in v9.3.0), #2716 (parent thread of #5237), #4416 (a different failure mode of the same setting when max_price is used). Not a duplicate: those tickets cover the slot-selection distortion and max_price modes; this one was the "planned car charging reads as charging-now" interpretation on an older default.
Describe the bug
I would expect the plan details to say the car is not charging, since the sensor is off?
