    Those who can do £/s/d, hundred weights/stones, yards/chains and nautical miles can count in many ways mostly without the help of Phobile Mone.

    Some of us still have slide rules and log-tables in the hangar for when the power goes down (and maps in the car)

    I just wish that the folks in the post office could count still, they often get it wrong even with a calculator.

    Happy and prosperous NY to one and all 🙂

     

     

    Especially if they use the Horizon calculator.....

    Not exactly a joke but...

    My 94 year old sister is in a care home, thinking of a Xmas pressie for her is always a problem. This year I thought a couple of pairs of non-slip slipper socks would be a great idea.    

    I picked a pastel pink pair first then thought a Xmas themed design would be nice for the second pair.  

    I was just about to hit the button on this pair Reindeer pattern when I took a closer look - then decided another pastel coloured pair would perhaps be more suitable for an old lady. 😁

    What on Earth were they thinking of....

    I see on the news that more of those awful pylons need to be erected to supply charging stations/points..... blinkin' eyesores!

    WiFi chargers are what we need!

    That is absolutely possible from an HA perspective once you have the myenergi plugin. I suspect Octopus might catch on though after a bit...!

     

    Yes, if the charger has an HA integration (my Ohme doesn't) that allows charging to be started and stopped from HA, then it should be easily possible. As you say, Octopus might catch on if you do this regularly as it is in breach of fair use policy. To be fair, if you have done your sums right and ordered the right size battery, you shouldn't need to (ab)use this facility very often and even then, a single half hour charging slot goes a long way.

    If you have a Givenergy system, I would recommend you just install PredBat which uses solar predictions, past usage information and upcoming tariff info (including your IO periods which it can get via the Octopus plugin for HA) to top up the battery intelligently to the minimum levels to get you through the day at least cost. I have ben running it for just over a week now, and it seems to be pretty good so far.

    PredBat is great for complicated tariffs like Agile, but not needed for Intelligent Octopus tariff. You get much better results if you just charge to 100% at 7.5p every night and at every additional opportunity, then export any solar excess at 15p if batteries are full. Also the Octopus Plugin (and therefore Predbat) does not report Intelligent Octopus charging slots made by Ohme chargers because they work differently to vehicle APIs.

  6. This is what the billing looks like for a day when the system decided to give me an hours charge in the early evening. To be honest, it seems to do that every time I plug in at the moment.

  7. I've been on Intelligent Octopus for a few months now. I can confirm that whenever your car is charging, any electricity used by the house will be at cheap rate. When the car stops charging, it reverts to full rate at the end of the current half-hour slot. Very handy for automatically topping up the solar / house batteries. It's never failed to bill me correctly for a single half hour slot. Brilliant tariff.

    Good stuff, thanks for posting that. I have logged back into the Octopus site, and have found the content that correlates to the second of yourpics on the FAQ page here: https://octopus.energy/blog/saving-sessions-faqs/

     

    However, whilst I am not doubting that you are correct, but there is clearly something screwy going on with the T&Cs links they are using on some of their website pages. If I log into my account, click on Octoplus rewards, then Savings session page, I get to a page with the URL https://octopus.energy/dashboard/new/accounts/[AccNoGoesHere]/saving-sessions (I remoived my account number for security reasons). If I scroll down that page, I get to the following:

    Click on the T&Cs link and I end up here - https://octopus.energy/saving-sessions-terms-conditions/ - which as you say looks like it is the old 2022/23 T&Cs. I can't find the T&Cs you have screenshotted above anywhere on their site - it's baffling! Can you post up a direct link to see if I can get to them? Thanks.

     

    PS - Can you share your Home Assistant automation so I can adapt it, assuming they ever let us participate in savings sessions? At the moment the website is telling me I can't despite meeting all the criteria on smart meter readings etc).  

    Octopus website is still evolving and some of the links need updating. The Q&A screenshot I posted earlier is hot off the press. It said the opposite about export until a few days ago but was updated to reflect this years T&Cs due to lots of people pointing out that they were contradictory.

    I'll try to send you the automation but it will need some work as it is written for dual inverters (everything done twice) and uses custom sensors and helpers. I'll send the sensor data too if I can pm it to you.

    Good point - those T&Cs do seem to cover the winter 22/23 period, I had not noticed that. They are definitely the T&Cs that are currently linked from Octopus Savings Events page, though.

     

    I will send them a question about this, but in the meantime can you point us to a source that talks about the payment for export during these periods? I've done a bit of Googling but can't find one anywhere...

     

     

    Yes, I get it's not primarily about financial savings to customers, but every little helps, especially for those who are struggling in this cost of living crisis. The bit I am really puzzled about though (assuming you are correct about people being paid more for export during these periods) is that lots of people with home batteries will charge them just before as you are proposing, creating an new artificial increase in demand just before the event. That doesn't sound like something they would want to do, but maybe the grid effect is relatively insignificant given demand in that period should be slightly lower and only a relatively small percentage of homes have a battery at present.

     

     

    The price paid and times / durations cannot / will not be published in advanced. They will depend on lots of factors including weather, peak demand, how many people have signed up etc. People will naturally charge their batteries at the cheapest rate (or from solar if available). The national grid actually want people to do this because it allows them to have the generators that require a lot of time to run up already running. It's the short term availability they need, such as from batteries or hydo to meet the peak demand in the early evenings. It's all about "balancing" the grid and paying £2.25 is a good price for them to pay peak for period electricity.
