# octopus_exporter
A Prometheus exporter for Octopus Energy smart meter data, using the Kraken GraphQL API.
## Metrics
### Electricity
| Metric | Description |
|---|---|
| `octopus_electricity_demand_watts` | Live electricity demand in watts |
| `octopus_electricity_last_read_timestamp` | Unix timestamp of last electricity reading |
| `octopus_electricity_unit_rate_pence` | Current unit rate in pence per kWh |
| `octopus_electricity_standing_charge_pence` | Current standing charge in pence per day |
### Gas
Gas metrics are only exposed if a smart gas meter is found on the account.
| Metric | Description |
|---|---|
| `octopus_gas_demand_watts` | Live gas demand in watts |
| `octopus_gas_last_read_timestamp` | Unix timestamp of last gas reading |
| `octopus_gas_unit_rate_pence` | Current unit rate in pence per kWh |
| `octopus_gas_standing_charge_pence` | Current standing charge in pence per day |
### Account
| Metric | Description |
|---|---|
| `octopus_account_balance_pence` | Account balance in pence (positive = credit, negative = debit) |
Metrics are updated every 60 seconds.
## Configuration
| Variable | Required | Description |
|---|---|---|
| `OCTOPUS_API_KEY` | Yes | Your Octopus Energy API key |
| `OCTOPUS_MPAN` | No | Filter electricity meter by MPAN |
| `OCTOPUS_SERIAL` | No | Filter electricity meter by serial number |
| `OCTOPUS_DEVICE_ID` | No | Use a specific electricity smart device ID directly |
| `OCTOPUS_GAS_MPRN` | No | Filter gas meter by MPRN |
| `OCTOPUS_GAS_SERIAL` | No | Filter gas meter by serial number |
| `OCTOPUS_GAS_DEVICE_ID` | No | Use a specific gas smart device ID directly |
| `PORT` | No | Port to expose metrics on (default: `9359`) |
If no filter variables are set, the exporter auto-discovers the first smart meter of each type found on the account. Use `OCTOPUS_MPAN` / `OCTOPUS_MPRN` to pin to a specific meter on accounts with multiple meters.
Your API key can be found in the [Octopus Energy developer dashboard](https://octopus.energy/dashboard/new/accounts/personal-details/api-access).
