octopus_exporter

A Prometheus exporter for live electricity consumption data from Octopus Energy, using the Kraken GraphQL API.

Metrics

Metric	Description
octopus_live_consumption	Live electricity demand in watts
octopus_live_consumption_last_read	Timestamp of the last meter reading (Unix epoch)

Metrics are updated every 60 seconds.

Configuration

Variable	Required	Description
OCTOPUS_API_KEY	Yes	Your Octopus Energy API key
OCTOPUS_MPAN	No	Filter by MPAN (recommended if you have multiple meters)
OCTOPUS_SERIAL	No	Filter by meter serial number
OCTOPUS_DEVICE_ID	No	Use a specific smart device ID directly
PORT	No	Port to expose metrics on (default: 9359)

If none of OCTOPUS_MPAN, OCTOPUS_SERIAL, or OCTOPUS_DEVICE_ID are set, the exporter will automatically select the first smart meter found on your account. For accounts with multiple meters, use OCTOPUS_MPAN or OCTOPUS_SERIAL to pin to a specific one.

Your API key can be found in the Octopus Energy developer dashboard.
