The most recent Matter Preview update for the Nest Hub and Nest Hub Max is going to disable the device’s bridge/extender functionality. The Nest Hub Max’s ability to increase some Nest devices’ usable range is one of its lesser-known functions. These devices rely on a conventional bridge device like a Nest Connect, Nest Guard, or the Nest Hub Max in place of connecting through Wi-Fi.
For Nest and Google Home devices, Google has updated a support website with information on the most recent stable and Preview Software packages. According to the updated listings, the Preview Program devices Nest Hub and Nest Hub Max will shortly receive the F7 update, with the smaller hub receiving 7.20220419.2.166 and the bigger 7.20220419.2.164. This will serve as the beginning of these switching to Matter’s unified IoT space.
The F7 update for Nest Hub and Nest Hub Max will not likely bring around many changes aside from the loss of the Nest bridge/extender functionalities. Google is urging those who are affected by the bridge feature removal to move their devices closer to maintain connectivity. However, if doing so is impractical for your place, the company is also providing certain customers with a free Nest Connect (as per some forums) that may act as an extension.
