Corrently

These are the Corrently actions available to the apps you build with Snow. Connecting an account does not make Snow run these on its own.

• Commit Strom-Quittung

  Tool to finalize a Strom-Quittung (electricity receipt) after collecting transaction data. Use after gathering seller, buyer, and transaction details to create the final receipt.

• Electricity Generation Mix

  Tool to retrieve real-time electricity generation mix in Germany. Use when you need the current breakdown of generation by source.

• Electricity Market Data

  Retrieve real-time and forecast electricity pricing data for Germany by postal code (Postleitzahl). Returns wholesale market prices (EUR/MWh) and localized prices for specific grid areas. Data is provided in time intervals with timestamps in milliseconds since Unix epoch. Use this tool when you need current or forecasted electricity prices for energy optimization, cost analysis, or smart grid applications in Germany.

• Energy Schedule Computation

  Create an optimized operation schedule for energy-consuming devices based on the GrünstromIndex (Green Power Index). This tool determines the best time slots to run energy-intensive devices (heat pumps, EV chargers, etc.) by analyzing regional renewable energy availability, electricity prices, and CO2 emissions forecasts. Use this after collecting: - German postal code (required for regional data) - Desired optimization goal (price, co2, or comfort) - Number of hours the device needs to run

• Get Metering Reading

  Tool to retrieve metered electricity reading with green/grey energy split and CO2 emissions data. Use when you need to check current meter readings or analyze energy consumption patterns for a Stromkonto.

• Get Stromkonto Balances

  Retrieve Stromkonto account balances from the energy blockchain ledger. Stromkonto is a ledger for green energy related transactions backed by Energychain blockchain to provide consensus of balances and transactions. Returns balance details across multiple sub-account types (green power bonus, generation, self-consumption, carbon offset, trees planted).

• Get WiM Process Status

  Retrieve status information for WiM (Wechselprozesse im Messwesen) metering change processes. WiM processes handle meter changes and allocation workflows in the German electricity system. Use this tool to check the current status of ongoing or completed metering change processes, track process progress, or verify when a WiM process was initiated.

• GrünstromIndex Forecast

  Tool to retrieve hourly green power forecast and CO2 data. Use after obtaining the user API key.

• GSI Best Hour

  Determines if now is the best time to turn on a device based on regional green energy (GrünstromIndex) forecasts in Germany. Returns true if the current hour has high renewable energy availability within the specified timeframe, false if waiting would be more sustainable.

• PHEV Navigator

  Tool to get PHEV charge-or-fuel recommendation for German locations. Compares real-time fuel prices at nearby stations with electricity costs to recommend whether charging or fueling is more economical and eco-friendly. Requires a German postal code (PLZ).

• Register Stromkonto Account

  Tool to register a new Stromkonto energy account in the Corrently system. Use when creating a new account with email, name, and location details. All balances are initialized to zero upon registration.

• Renewable Energy Dispatch

  Tool to get renewable energy flow and mix for a German ZIP code. Use when you need import/export and dispatch sources/destinations breakdown.

• Standard Load Profile Tariff SLPH0

  Tool to retrieve standard load profile H0 tariff information. Use after providing a German postal code to get local SLPH0 tariffs.

• Tariff Components

  Retrieve detailed German electricity tariff cost breakdown by postal code. Returns comprehensive cost components including: - Grundgebühr (base monthly fee) - Arbeitspreis (energy price per kWh) - Network fees (Netznutzungsentgelt) - Taxes (Stromsteuer, Mehrwertsteuer) - Levies (EEG, KWKG, Offshore-Netzumlage) - Renewable energy credits Use this tool to understand electricity pricing transparency in Germany.

• TyDID Consent Status

  Check TyDID consent/grant status for an SSI (Self-Sovereign Identity). This tool queries the Corrently TyDID API to verify whether a given Ethereum-based identity has granted consent or if the consent has been revoked. Use cases: - Verify user consent before processing data - Check if a user has revoked access to their data - Monitor consent status changes in blockchain-based identity systems

• Weather Forecast

  Tool to retrieve hourly weather forecasts (wind speed and UV index) by geographic coordinates. Use when you need wind and UV data for a specific location. Returns up to 5 days of hourly forecasts.

• CO₂ Meter Update

  Tool to create or update a CO₂ meter reading for emissions tracking. Use when sending new or updated electricity consumption readings to Corrently.

• Geocode Location

  Tool to geocode a free-text location into coordinates. Use when you need latitude and longitude from a place name.

• Get Stromkonto Choices

  Tool to get selectable contract choices for a Stromkonto customer. Use when you need to retrieve available balance and transaction options for an account.

• Login to Stromkonto

  Tool to initiate login to Stromkonto via email. Use when authenticating a user with their email address.

• Post Metering Reading

  Tool to post a meter reading and get it decorated with green/grey energy split. Use when you need to split consumption readings into green power (1.8.1) and grey power (1.8.2) according to the local GreenPowerIndex value.

• Prepare Receipt Data

  Tool to collect data for a receipt before finalizing. During the first call, an account parameter will be returned. Use this when you need to incrementally build receipt data through multiple requests. Call without an account parameter first to create a new session, then use the returned account identifier in subsequent calls to add more data.

• PV Generation Forecast

  Get hourly solar PV generation forecasts for a German location. Returns predicted energy output in watt-hours (Wh) for each hour over the specified forecast period. Use this tool when you need to optimize energy scheduling, estimate solar production, or plan energy storage based on expected PV generation.
