Agile Octopus integration

You’re quite right, above all it needs to be simple! The beauty of WW is that it’s largely automatic when set up, and the time-slot grid makes it very intuitive to manually add or remove slots on an ad-hoc basis.

I’m going to run for a few days with multiple Charge windows and see how I get on (23:00-06:00[hold charge] & 06:00-23:00[discharge]). Obviously I’ll lose out on the optimal selection of low-cost slots, but hopefully this won’t be significant.

I am concerned that this approach still doesn’t stop my house battery occasionally dumping into the car, in situations when the last automatic slot ends before the car is fully charged. The only real solution to this would be your suggested ‘exclusion hold-charge' window in the Advanced tab?

Tell me to shut up, but how about keeping the ‘Agile Octopus’ side bar simple and adding another side bar duplicating it but include the greater flexibility as discussed above with the bells and whistles added? Call it ‘Agile Octopus Pro’ or something.

admin I'm sure this may have been discussed but will there be a monetary based charge option instead of timed . I've only been playing with charging and discharging batteries for a few days and I'm not great at this kind of thing but as far as I can work out you will have to go in every day and change the charge/ discharge slots depending on price change ? What most of us need I feel is an option to fill at lowest prices , sell at highest prices , I know some people are really tech savvy but those of us that aren't spend ages trying to configure all these things

I am finding the app really useful for taking advantage of the cheapest slots to charge up my battery.

Looking ahead to the return of the sun, how about showing an estimate of solar production for the next day, and better still showing it for each 30 minute Octopus Agile slot?

This would help users understand what is going on and to tweak their charging schedules. And it would also allow you to gather feedback and improve the algorithm for estimating solar production.

Thanks

In mid summer it is (almost) always sunny enough to be generating. In mid winter it is (almost) never sunny enough to be generating. In between there are some days with sunny spells. For example yesterday I was surprised by good sun from 10.00 till 13.00.

I accept that trying to estimate generation per half hour could be overkill. But how about highlighting, across the half hour schedules, periods where sun is forecast? I have a Tado heating system, and this is what the Tado app does.

Hello! I have been using WonderWatt for a few days now and really like the goals of the application, thank you for developing it.
I'm on Octopus Agile and have found WW's identification and programming of the cheap slots to work well. However, the WW strategy for these slots is slightly different to how I was setting them manually - I was setting each time slot and its upper SOC% goal. This would mean that once the battery had reached its goal during the time slot the lower-cost grid would still be active for my load shifted appliances. The WW scheme seems to be reliant on my having set the time slot's SOC% target but this loses one of the advantages of the regular WW scheduled scheme: to modify the SOC% according to the following day's sunshine forecast. It would be great if WW could bring that functionality to the Agile programming scheme. Thank you.

NickMalcolm I’d vote for this too. Now we are seeing some sunshine, I can throttle back on the overnight charging.

Prior to using WW I had two charge slots. Looking at the logs it seems WW only sends instructions re AC charge slot 1, leaving charge slot 2 untouched. I think this means charging is kicking in during the old slot (1-4pm) even when WW is chosing specific half hour slots in that period. Guessing I should manually delete the second charge slot on the Giv portal?

Setting a maximum soc target at the end of the charging period on Agile tariff would be a great addition, along with an indication of next days total solar generation forecast.

Not sure setting max soc target per 30 minute slot is required as I've not found the cost difference between 6-8 slots isn't that much (of course we all like to save as much as we can, but not at the cost of extra complexity in WW).

Having WW set the maximum soc target automatically based on solar forecast is the ideal solution, but I'd still like to have an over-ride based so I can set my own maximum soc target.

Curious as to why the hold instruction at 05.01 was sent twice, 2 seconds apart.
