Using Wiggle

Why your figures can change

Some energy data arrives late. Until it arrives, Wiggle shows what it can work out, and it marks that figure as estimated.

What "Estimated" means

Wiggle works out costs from your usage and your tariff's rates. It marks a figure that it has worked out with "Estimated" or "est.". "Estimated · incomplete" means that part of the data has not arrived yet.

A Cost today card that says Estimated cost today, £1.43, including today's standing charge.

Why data arrives late

If you have a Home Mini, Wiggle gets readings close to the time they happen. The half-hourly figures from Octopus come later. Without a Home Mini, Octopus usually sends your readings about a day late, and occasionally later. You do not need to do anything, because Wiggle keeps checking Octopus.

Why a cost can change later

  • Octopus's figures arrive. When Octopus's half-hourly readings arrive, Wiggle uses them in place of the earlier figures.
  • A rate is confirmed. Smart charging rates stay estimated until Octopus confirms them.
  • A charging cost is confirmed or corrected. A charging session's cost shows as "Supplier estimate", then "Supplier confirmed" or "Supplier corrected".
  • Missing data arrives. A total that was short rises or falls when the rest of its readings arrive.

If you want to know when Octopus corrects a charging cost, turn on Supplier cost updates in your notifications.

Messages that you may see

  • "Octopus live readings delayed". Octopus has not returned new readings yet. Wiggle shows the latest one and keeps trying.
  • "Octopus live readings unavailable". Wiggle cannot reach Octopus at the moment. It keeps trying.
  • "Octopus needs reconnecting". An owner must enter the current key.
  • "Wiggle delayed". Wiggle could not process the latest Octopus data. If this continues, write to us.
  • "Energy readings are incomplete". The total covers only the readings that have arrived in the last 24 hours.
  • "Still importing this home". Your first import is not complete. This usually takes a minute or two.
  • "Octopus reported no electricity use for this day". The home may have been empty, or the meter may have a problem, so the cost is incomplete.

If a past day is missing

Open that day on the Timeline. Wiggle asks Octopus for it and says "Fetching this day from Octopus…". If Octopus has nothing for that date, Wiggle says "No Octopus history for this day". Missing readings are never counted as free.
