Explore API availability to get Octopus Home Mini real-time meter readings

[ryanw-mobile]

Octopus Energy sent us the home mini device that works.
Try to see if any existing GraphQL API can return if a home mini is registered under the customer account, and if it is possible to grab the real-time meter readings like their official app.

If so, there are many new features we can combine the real-time readings and the Agile tariff unit rates.

GraphQL Query:

query getSmartMeterTelemetry($meterDeviceId: String!, $start: DateTime, $end: DateTime, $grouping: TelemetryGrouping) {
  smartMeterTelemetry(
    deviceId: $meterDeviceId
    start: $start
    end: $end
    grouping: $grouping
  ) {
    readAt
    consumption
    demand
    __typename
  }
}

Data sample:

{
  "end":"2024-11-20T02:11:06.734Z",
"grouping": "TEN_SECONDS",
"meterDeviceId": "XX-XX-XX-XX-XX-XX-XX-XX",
"start": "2024-11-20T02:10:06.734Z"
}
