    Does anyone know how the half-hourly readings are obtained from SMETS 1 meters. In particular:

    - Does the meter send the usage in real-time at the end of each half hour?, OR
    - Does it accumulate a day's readings in half-hour chunks and then send the whole log on a less-frequent basis (e.g. daily)?

    I found this doc which implies it's the latter, but would be good to know.

    I'm asking this because I've had the run-around with Octopus on moving to the Go tariff. I have a Secure-branded SMETS 1 meter from my previous supplier that Octopus say they can use. However, so far they have been telling me that they can't get half-hourly readings so can't switch me. After endless calls and mails where they were recommending that I installed a mobile phone network signal booster (SMETS 1 uses the mobile phone network to communicate), they eventually agreed to install a SMETS 2 meter (which uses a different radio network). I've been waiting for an appointment for this.

    Suddenly though, I got an e-mail out of the blue saying that I could not join Go. Sure enough, on my account page I can now see half-hourly readings. My concern though is that the half-hourly readings may stop as randomly as they started, and if that happens I'll drop back to Octopus's variable tariff - which is 4-5 times the cost of the Go tariff. That risk would be higher if the meter strategy was to send readings each half-hour. I do have weak mobile signal where I live.

    My suspicion is that actually the meter needed, and has now received, new firmware to collect the half hourly readings - but trying to get any sense out of the help desk there is sort of difficult.

    I'm on Octopus Go, on my "Secure" SMETS 1 meter that was installed by Ovo several years ago (I moved to Octopus 3 or 4 months ago). Everything was seamless. I don't know if that means you have a genuine problem with your meter, or if Octopus are struggling with increased demand?

    Thanks for the reply. I'm moving from Ovo too. I've now had four days of solid half-hourly readings, so hopefully all is OK. Trying to speak to them now.

    Actually - whilst the process has been less than ideal and has involved lots of calls/e-mails, at least they do respond. Unlike Tesla - well, we all know what they're like!

    I'm almost certain that it sends a batch of readings. It's not uncommon for my Octopus account to lag a day or two and then for all the readings to be available a day later. I presume that this means that it can better cope with a flaky data connection where it may not be able to have a guaranteed continuous real-time data connection.
