# Product updates

> Updates and Changes

<Update label="August 2026">
  ## Device data availability after connecting

  * Clarified in the [Energy Supplier Integration](/guides/energy-supplier-integration) guide that device data may not be immediately available after a user completes the Authenticator flow, as the connection may still need to finalize on the manufacturer's (OEM) side. The [/devices](/api-docs/full-control/asset-info/get-devices) endpoint may return an empty result right after connecting. We advise polling for up to 10 minutes while showing a pending state to the end user.
</Update>

<Update label="July 2026">
  ## PV production webhook event

  * Added the `device.state.pv_production.updated` webhook event, which delivers the current PV production reading (in kW) whenever it changes. See [Partner webhooks](/guides/partner-webhooks#subscribable-event-types) to subscribe.
</Update>

<Update label="June 2026">
  ## PV response latency

  * The `GET /v1/devices/pv` endpoint now returns a `response_latency_seconds` field, indicating the expected latency in seconds before the device responds to a steering command.

  ## PV production measurement timestamp

  * The `GET /v1/devices/pv` endpoint now returns a `last_updated_at` timestamp alongside `current_production_kw`, indicating when the production value was last measured. Treat `current_production_kw` as the current production only if `last_updated_at` is recent (e.g. less than 5 minutes in the past).
</Update>

<Update label="March 2026">
  ## Production API update and new Authenticator

  * Removed House predictions endpoint
  * Removed flex up/down endpoints
  * Added current production api endpoints
  * Added integrated authentication endpoints
  * Added energy supplier and manufacturer integration documentation
</Update>

<Update label="July 2025">
  ## House predictions update

  * Updated House predictions to be executed at 9:45 CET/CEST instead of 10:00 CET/CEST
  * Updated from what time house predictions are done.
    * Old version: House predictions predicted the house consumption from now until the next 72h.
    * Current version: House predictions predict the house consumption for 72h starting from upcoming midnight 00:00 CEST/CET.
</Update>

<Update label="June 2025">

  * Redesigned the Nox Energy API documentation website to be more clear and structured.
  * Added extra guides on how to get started with the Nox Energy API.
</Update>

<Update label="March 2025">
  ## Nox Energy API Launch v1.0.0

  * Official [Nox API](https://api.nox.energy) and [Sandbox API](https://api.sandbox.nox.energy) launched! 🚀
  * API endpoints to list device information.
  * API endpoints to get historical and forecasted consumption data per asset or aggregated.
  * API endpoints to get house consumption forecasts
  * API endpoints to get current flex up/down and execute an amount of energy of flex across devices.
