@HungryHippos that does sound complex, but hopefully once setup it will just work.
How to getthe best out of Octopus Flux
- Thread starter Ron-ski
- Start date
@SoliD Hugo, Loop and Bright don't show export yet
Hi @d_p welcome to the forum, I've quoted your message in this thread as it's more appropriate. I'm not familiar with Growatt but I'm sure someone here will be.
A lot of people use Home Assistant, try googling "growatt home assistant"
Have you tried Octopus Watch (Android) or Octopus Aid (Apple), they won't do what you want but help with a day to day picture of you're costs.
I would say I'm really looking forward to our next electricity bill, but as BG have not responded to my email informing them not to pay me deemed exports yet, I can't be paid by Octopus.
Currently last 7 days are -£24.25, last 28 days are -£35.35, but 11 days of that don't have any export included.
PS That's the thing I found, you start out thinking you have all this "free" electric, then Flux comes along and it's not "free" anymore, if you use it, it has a cost, as in lost export payments.

I basically do the same as above:
I currently only have 14.5kWh of battery, but in a couple of weeks will have another battery, so will have circa 29 kWh of storage, and will lower the target SOC to reflect that.
- Charge battery off peak (maximum charge circa 24kWh, 8kw x 3 hours)
- Solar tops battery up to full - capacity circa 14.5 kWh
- Excess is exported at more than we paid per kWh to charge the battery
- Discharge some at peak rate down to 65% SOC, but keep some back to see us through to 2am and in case of a power cut.
- Repeat the above.

@HungryHippos Mines the same, except always between 14 and 15 kWh.
Minus £7.98 for yesterday, takes me to minus £77 for the last four weeks 
No cheating involved, just large mirrors on the surrounding houses
@Jonners59 welcome to the forum.
That's the gist of it, it's a time of use tariff, so you pay more to import when demand is high (16:00 - 19:00), and less when demand is low (02:00 to 05:00). But the most important part is the export, you get a really good export rate during the day, more than what you import at in the cheap rate period. Then in the peak rate you get an even better export rate.
I aim to fully charge my battery off peak, then export excess, discharge some from the battery in the peak period, and leave enough to last to 2am.
It's different for everyone, as the use case varies, but if you're going to have excess generation then its a good tariff to be on, but I don't have an electric car, so that will alter things. My electric bill for the last 28 days is minus £105, which more than covers my gas bill.

Octopus Flux
The UK's most awarded energy supplier. We're doing energy better - for you and the environment.
octopus.energy
I finally got confirmation from British Gas that I won't be paid for exports, so hopefully Octopus will process that quickly and start crediting my account.
Friday was a dredful day, with just 9.2kWh generated, and 5.2 kWh exported, and 14kWh imported, Friday's electric cost was £1.80.
I'm intending on staying on Flux for simplicity, but I do have circa 29kWh of battery storage, and can charge at 8kW during the off peak period, along with 8.74kW of PV I'm hoping it will work well, I expect December and January to be the worst months.
For Android use Octopus Watch.
Once it updates today, the last week for electric should be about minus £50, and minus £90 for the last 80 days, which takes in a month when we weren't on Flux export.
Looking forward to my next bill as well, but the electric bills seem sporadic so far.

How frequent do people get their electric statements?
I haven't had one since 7 March, also noticed if I click to request a refund, it says I can't as I haven't given a meter reading recently, which is odd given they are getting half hourly smart meter reads. Is this normal?

Thanks, I'll chase them tomorrow, had been waiting for all the other bits to get done, last thing was Octopus confirming that they've received the email that BG are no longer paying me deemed export, which they did about a week ago.
Should have a nice amount of export credits in the bank, Saturdays recording breaking day was a -£10.37 for our electric bill according to Octopus Watch.
1478 kWh exported so far according to Octopus mobile app, the website is broken if I select a year, it tells me "It looks like there aren't any readings after the 29th May 2022" which is kind of weird, just twigged it says 2022.

Nope, mine are there.
@reef Mine was a little different but took 4 weeks.
There's a poster on https://forums.moneysavingexpert.com/discussion/comment/80089494/#Comment_80089494 that is at -£79 for the week 
@bigmike20vt but was you already being paid for exports by Octopus? Thats what seems to make the difference, if you're exports are with another company it takes time to transfer things over, if already with Octopus its quick.
