No charging schedule set in pv_opt

[punkymuzzle]

Describe the bug
pv_opt hasn't scheduled a charge in a number of days.

To Reproduce
pv_opt normal schedule

Expected behavior
Pv_opt should schedule charges more accurately.
Charging schedule:

Todays rates:

This has been for about a week now,
Logs attached:
error.log
pv_opt.log

[punkymuzzle]

Just rechecked after the new hourly rates have landed.
Still no charging slots allocated.
Here's the tariff:

Charging Schedule:

Here's the entry from the log:

I would expect it to charge to ate the very least cover the expensive slots between 16:00 and 19:00

Log attached fyi.

@punkymuzzle , no expert on this, but I belive what you seeing is all in the logs

If you would to change your "Pass threshold" to 1 it would help, but maybe not costs-wise. The other thing I'd look at that potentially solcast is also playing a role of predicting enough generation to not trigger charge - if you flick "Use Solar" off, I'm sure there will be charging scheduled for the cheap period - otherwise I'd expect that due to your solar forcast the expectation would be that it will be charged from the panels as not cheaper to import?

[SzosszeNET]

Besides your cost summary is negative due to your exports?

So yeah, maybe play with the pass treshold that that might help here but not sure if it would make a massive difference?

Mine is the exact same at the moment - overnight slots aren't cheap enough to be worth using and the solar is enough to get me past the peak.

[punkymuzzle]

Thanks both, much appreciated.
If it's not just me that's experiencing this then that gives me a little more confidence that it's working as it should.

Does pv_opt keep recalculating based on solar prediction as well as SOC?
The reason I'm asking is that it was quite cloudy here for most of the day so by 13:00 my SOC was still only at about 30%, so I had to intervene and set a charge before the peak period of 16:00 - 19:00.
Probably my misunderstanding but I thought that pv_opt would have calculated that I needed a charge to get up to 100% SoC?

Thanks

Thanks for this. I did turn off the Use Solar" option and yes it did recalculate and provide me with charging slots, so it looks like it's actually working.

However, it's recommending charging slots overnight to get the SoC high enough to cover the more expensive 0600 - 1000 slot (which I feel is right). But I would have though that it would do this anyway, even if the "Use Solar" was enabled?
Maybe when you take the cost to charge and the inefficiencies for the round trip in the electricity, it might not be worth it if there is some solar at 0600. Not sure....

It's a bit of a moot point at the moment though I guess, as I still have an issue with my inverter going idle at 10%, so pv_opt can't write any charging schedule to it until the inverter comes out of idle (SoC > 10% due to solar charging or me setting a charge via the app).

Thanks

Hmm, okay - I played with the parameters a bit - looks like that the solcast confidence is producing something unexpted.

with 40% confidence it appeared have scheduled charge and discharge slots

But again messing with the load history 7 vs 14 days does seem to produce the same charge / discharge only scenarios.

Thanks for the input. Think this can be closed now I know it's working OK
