ioBroker.octopus-energy-monitor

The Octopus Energy Monitor adapter periodically fetches daily electricity consumption data from Octopus Energy (Kraken API) and Inexogy (Discovergy/Statistics API), saving it automatically within your ioBroker object tree.

Its key purpose is identifying discrepancies in billing/measurement between your intelligent smart meter (Inexogy) and your energy supplier (Octopus Energy). Every night, the adapter compares both datasets and flags daily discrepancies that exceed a configurable threshold mathematically.

Features

• Full Kraken GraphQL Support: Authenticates via your Octopus JWT tokens and dynamically resolves account properties to fetch precise consumption data.
• Dynamic Tariff & Slot Support: Automatically detects your active Octopus tariff (e.g., Intelligent Octopus Go) and its specific time-of-use slots. No manual configuration of "Go" hours needed!
• Automated Cost Calculation: Automatically calculates daily, monthly, and yearly energy costs in Euro (€) based on your actual tariff rates.
• Hierarchical History: Structures data in a clean history.YYYY.MM.DD tree with automatic aggregation of consumption and costs for months and years.
• Estimated Meter Reading: Calculates your current electricity meter reading by combining the latest official Kraken reading with your subsequent daily consumptions.
• Inexogy (Discovergy) Comparison: Leverages the Inexogy API to compare consumption data against your provider's data, helping identify billing discrepancies.
• Master Data Insight: Provides transparency into your account balance, meter details, and involved network operators (MOP/DNO).
• Smart Charging Control: Dynamically fetch Intelligent Octopus devices (EVs/chargers) and toggle Smart Charging (Suspend/Resume) directly from ioBroker.
• Inexogy Master Data & Live Reading: Fetch serial numbers, location details, and current meter readings (Bezug/Einspeisung) from Inexogy.
• Smart Caching: Minimizes API load by retroactively syncing only missing data points (30-day default).
• §14a EnWG Price Calculation: Optional tariff calculation for controllable consumption devices (Steuerbare Verbrauchseinrichtung) with custom time windows (NT/HT) and automatic standard tariff (ST) fallback.
• Custom Billing Periods: Aggregates and tracks energy consumption and costs based on your custom billing period start day (e.g., 18th to 17th) under the octopus.periods channel, split by standard rate slots (e.g. Go/Standard) with a static current folder for easy visualization.

Installation

To install this adapter in your ioBroker environment:

1. Open your ioBroker Admin UI.
2. Navigate to the "Adapters" tab.
3. Search for "Octopus Energy Monitor" (or octopus-energy-monitor).
4. Click the + (add) button next to the adapter to create a new instance.

Configuration

1. Octopus Energy (Kraken):

   • Enter your standard Octopus login credentials (Email & Password).
   • Input your Account Number (usually starts with A-).
   • Billing Period Start Day: Day of the month on which your billing cycle starts (default is 1 for normal calendar month). If your cycle is from the 18th of one month to the 17th of the next, select 18 to generate the billing period folders under octopus.periods.<startDate> and a static octopus.periods.current alias, including slot-split metrics.

2. Inexogy:

   • Enter your Inexogy portal Email & Password. The adapter automatically manages Basic Auth parsing and translates it into Discovergy API queries.

3. General Settings:

   • Discrepancy Threshold: Defines how many kWh difference must be present between Octopus and Inexogy to trigger the hasDiscrepancy: true state flag. Default is 0.1 kWh.

4. §14a EnWG Settings (Optional):

   • Enable § 14a EnWG Calculation: If activated, calculates daily energy prices taking into account reduced grid fees for controllable consumption devices.
   • Applicable From Date (YYYY-MM-DD): Defines when the EnWG calculation should start. Changing this date (or grid fees/time windows) triggers an automatic retroactive recalculation of all historical data.
   • Grid Fees: Input your local NT, HT, and ST grid fees. Use the checkbox to specify whether the input values are gross (including 19% VAT) or net.
   • Configured Time Windows: Define your local NT (low tariff) and HT (high tariff) times per month. Times that are not defined automatically fallback to ST (standard tariff). Windows must not overlap within the same month.

Once configured, the adapter handles the rest! It sets an internal Cronjob scaling back 30 days every night. Data manifests under the octopus-energy-monitor.0.history.YYYY.MM.DD path.
