One license unlocks both protocols; however, only one integration method can be active on a gateway at a time (either Modbus or MQTT). You can switch between them if needed. ### Available license terms (SKUs) Available time periods for purchase: * **1 year** * **3 years** * **Unlimited** Some integrations may include extra parameters. These can enable additional features or allow specific configurations. {% hint style="warning" %} Important: When ordering, please provide the serial number of the Aranet Gateway Pro. Each Integration License is generated for an individual gateway and is automatically linked to that specific device, so it can be activated and used only on the Gateway Pro it was issued for (no license file upload is required). {% endhint %} [Purchase Aranet Gateway Pro Integration license](https://aranet.com/en/pro/products/aranet-gateway-integration-license-1-year) ### How licensing works on Gateway Pro The Gateway Pro does not use local license files. License information is stored in Aranet services. The Gateway Pro retrieves its license status from the server. ### Offline behavior After activation, the Gateway Pro keeps the last known license status until it expires. This lets the Gateway Pro keep operating without an internet connection. ### Activation Once a licence is purchased through e-commerce or via a sales manager, it remains inactive until a Cloud-to-Gateway integration is enabled. The licence is automatically activated the first time this integration is enabled. As a result, the licence expiration date is calculated from the activation date, not the purchase date. {% hint style="info" %} Unlike Pro base station licences, the validity period begins at activation and continues regardless of actual usage. {% endhint %} At the moment of activation, the expiration date is determined based on the licence duration and stored on the device. The licence remains valid until this date, irrespective of whether it is actively used during this period. The Gateway Pro automatically selects and activates the appropriate licence. The remote licensing system is used solely for storing and managing licence information. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://help.aranet.com/gateway/gateway-pro/gateway-pro-configuration/integration-licenses.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
