Saving Sessions / Demand reduction thread

Not bad!
19/11 £14.18
01/12 £17.58

Not sure i am going to bother with tonight's at £2.50kwh, not so much the rate but I forget to disable forced discharging so I have been dumping to grid during those peak hours since the last session on 01/12 and so my trailing 10 day average export in those hours is going to be unhelpfully high! :o

Its £2.25 tonight

bear in mind calculation is based on weekdays (as today is a weekday) and excludes saving sessions so it should actually only be 1 day that is in scope (yesterday)

Realllllly helpful thank you. I'm back in.
I saw that they also exclude previous Octoplus slots.

I should really automatethe force discharging trigger to "Octopus Energy Octoplus Saving Session" in HomeAssistant.

Yeah I need to do this but I'm struggling to get the triggers working properly for when I get extra intelligent slots so not trusting it for this.
 
Cut them a little slack, it was just before the weekend and they have to process everything from what id assume is millions of customers.

Although by now they should have found a way to automate the process.

For the first time ever today my setup missed the end of IO this morning and therefore my house kept running off of the grid instead of batteries which were chilling there at 100%. It should have been at 7am. For reasons I haven't yet worked out it went unavailable last night and only came back at 09:12, which didn't trigger my battery then either as IO went from 'unavailable' to 'off' rather than 'on' to 'off' as was required in the automation (since changed). I now also have a time-based switch-off to toggle the charging off at 7am in case this happens again. My car is set in the Octopus app to always be ready by 7am so I cannot see them ever giving me a slot after 7am in the morning.

Logbook:

5 December 2023​

Octopus Intelligent Slot turned off
09:12:27 - 4 hours ago
Octopus Intelligent Slot became unavailable
02:56:03 - 10 hours ago

4 December 2023​

Octopus Intelligent Slot turned on
21:30:01 - 15 hours ago

On the plus side I've just plugged my car in and they've given me 14:30-16:00 today which is mega. Good on them.

I now see that while binary_sensor.octopus_intelligent_slot and binary_sensor.octopus_intelligent_planned_dispatch both of which are part of the "Octopus Intelligent Tariff" HACS app went offline, octopus_energy_a_****_intelligent_dispatching from the Octopus integration worked fine so I am adding it to my OFF automation. I do not use it for ON as unlike the first sensor I mention I do not think that dispatching turns off if the car is not plugged in/charging.

Seperately, I am quite impressed that my smart meter's IHD reflects the correct pricing even during IO slots during the day.

So I've done 1 or 2 saving sessions already but still not seen any points come through or any mention of the results. Does that mean I saved sweet fa?
 
Also opted in, though I don't think I'll have the battery left for the full hour today.

Just charge it now and discharge in the session, simples. It will be worth it I think.

I turned my batteries and inverter off earlier for a couple of hours - will turn it back on in a little while to guarantee still having enough battery during that slot as had a big load of washing on earlier and the tumble drier so pulling that load from the grid which should guarantee enough battery later today.

I get around this by setting charge and then a % SOC, once it's reached it just holds the rate at my target SOC %.

I've set the car to be ready by 05.00 and then got a change in the system to then set it to 11.00 at 5.30 to get some extra morning hours as they are always offered. Just need to get this triggering the charging of my battery now.

What battery system do you have, do you not have an option to pause discharge between certain times?
 
Watch out for pause discharge, I read on GE forums that doing so causes it to re-evaluate SOC and can be a cause of the SOC drop, even on non-AIO inverters.

Apparently it shouldn't do it's evaluation if the battery is over 50% or currently importing/exporting more than 200W.

I tried when I had 1kwh left and battery was saying nearly 30% on SOC I paused discharge for 45m hoping it would adjust, it didnt. SOC drop should happen if SOC is higher than what remaining capacity you have left.

EDIT
misread and you said over 50% but I have paused discharge between midnight and 10am before and charged with agile during lowest points and its been absolutely fine.

I've currently got 62% SOC, I think I'll be ok to cover the hour of forced discharge then the last half hour to 19:00 as self use, don't want to be pulling power at peak rate.

Will need some sun tomorrow, as the battery is not going to get fully charged off peak tonight - it hasn't for a few days now.
