Users often own multiple energy devices from the same vendor. For example, home energy devices such as solar inverters, batteries, or meters are frequently purchased together as a package, with their API access managed under a single vendor account.

To improve the linking process of different devices under the same account, we have enabled the re-use of vendor authentication across different device categories. Users after the initial linking flow, are able to skip repeating the same step of entering credentials with all subsequent sessions with LinkUI automatically using the previously granted authorization of the vendor account. This reduces friction and enhances the overall user experience.
