You can now retrieve live smart meter consumption and import/export data via our API.

This provides real-time insight into site-level electrical usage, helping with diagnostics, load management, and energy optimization.

What’s new?

• List Live Smart Meter Data – fetch instantaneous power, import/export values, and phase-level readings from a specific smart meter.

This helps users track consumption and grid interaction in real time, enabling more accurate reporting, alerting, and energy balancing.

Access control

This endpoint requires the correct API roles and permissions. If you receive a 401 (unauthorized) or 403 (forbidden) error, your account may not have the necessary access. Please contact your account administrator or support team for assistance.

You can now retrieve live EV charger session data via our API.

This enables real-time visibility into ongoing charging sessions, supporting faster diagnostics, session monitoring, and energy reporting.

What’s new?

• List Live Charger Session Data – fetch the current power output, energy delivered, and session status from a specific charger.

This allows users to monitor charging behavior in real time and integrate live charging metrics into dashboards, analytics tools, or energy management systems.

Access control

This endpoint requires the correct API roles and permissions. If you receive a 401 (unauthorized) or 403 (forbidden) error, your account may not have the necessary access. Please contact your account administrator or support team for assistance.

You can now retrieve live solar inverter production data via our API.

This provides real-time visibility into how each inverter at a site is performing, enabling faster diagnostics, performance monitoring, and energy reporting.

What’s new?

• List Live Production Data - fetch current solar energy production readings from a specific inverter.

This helps users monitor solar output in real time and integrate live production data into dashboards, analytics tools, or energy management systems.

Access control

This endpoint requires the correct API roles and permissions. If you receive a 401 (unauthorized) or 403 (forbidden) error, your account may not have the necessary access. Please contact your account administrator or support team for assistance.

You can now retrieve a list of all grid connections associated with a specific address via our API. This enables better visibility into how a site is connected to the wider energy grid, supporting planning, compliance, and operational use cases.

What’s new?

• List Grid Connections – fetch all grid connection records linked to a given address.

This helps users map and manage their physical energy infrastructure more effectively, especially in complex deployments involving multiple connection points.

Access control

This endpoint requires the appropriate API roles. If you receive a 401 (unauthorized) or 403 (forbidden) error, your account may not have access. Please contact support for assistance.

You can now retrieve detailed information about HVACs and batteries installed at a specific address via our API. This supports better insights into distributed energy assets and improves energy system planning and monitoring.

What's new?

• List HVACs - fetch all HVAC systems linked to an address.
• List Batteries - retrieve all associated battery based on an address.

This makes it easier to understand and manage on-site energy infrastructure - whether for asset tracking, system optimisation, or analytics.

Access control

These endpoints require appropriate API roles. If you encounter a 401 or 403 error, your account may not have the required permissions. Please contact support if needed.

From raw smart meter data to clear delivery/return forecasts

We’ve expanded our smart meter capabilities to include forecasting for both electricity delivered to and returned from the grid. These forecasts are particularly useful for planning energy usage, optimising self-consumption, or supporting dynamic tariff models.

What's new?

• Delivery forecasts estimate upcoming grid consumption for a given address and smart meter.
• Return forecasts estimate the expected feed-in to the grid, typically from sources like solar PV.

This provides a more complete picture of future grid interaction, helping systems anticipate and adapt energy behaviour more intelligently. These forecasts are generated using historical smart meter data combined with local weather and usage patterns.

Access control

As with other energy forecasting features, these endpoints require specific API roles. If you receive a 401 or 403, your account may not have access. Please contact support for assistance.

From Sparky P1 to Historical data under /energy

As we're moving to more categories, we're moving away from reporting energy directly from Sparky. As we're collecting both P1 as well as P4, we've decided to move anything historically on energy to a specific energy endpoint.

Introducing production forecasting for solar

Our latest forecast renders for individual addresses with PV installations can be queried via solar-inverters endpoint.

For both of these endpoints additional roles are required. If you get 401/403 you might not have the appropriate rights. Please contact support if there are any issues.

Please follow the latest documentation to move from v1 to v2.

In the latest release (v2) we've included smart devices as API endpoints. These allow developers to query for smart appliance connections being made on a specific address. In the future, we'll unlock control functionality through the same route.

As of September 26th 2025, we've released version 2 of our API. While we transition to v2, v1 is available, but starting deprecation. Swagger documentation will provide the v1 functionality, but will show grayed out. V2 is available in public beta and will be pushed to production in the coming weeks
