Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: GA01331
What that covers: Google Nest/Home device; Matter/Thread role, wired/battery power, subscription and Google Home migration vary.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Display: A 7-inch touchscreen in a 4.7 in high by 7.0 in wide enclosure.
No camera: This model has no camera at all — unlike the Nest Hub Max, which does. Any instruction involving video calling, camera-based gestures or a camera shutter belongs to the Max and not to this device.
Audio: A full-range speaker and 3 microphones.
Sensors: Soli, Ambient EQ and a temperature sensor. Soli is a radar sensor — it is what supports presence and gesture features without a camera, and it is also why this model can behave as though it sees you when it has no camera.
Power: A DC power jack and a 15W power adapter. There is no battery, so it stops with the power and returns with it.
Connectivity: Wi-Fi, Bluetooth and Thread. The Thread radio matters: this device can act as infrastructure for Thread accessories in the home, so removing or replacing it can take other devices offline.
Platform: Matter compatible, with an ARM CPU carrying a machine-learning hardware engine for on-device processing.
Power path: Mains adapter into a standard outlet. Switched outlets and outlets on a circuit that trips are the two failure modes that present as device faults. Use the supplied adapter — third-party adapters that supply the right voltage at the wrong current are a common cause of intermittent restarts.
Radio: Thread mesh, which needs an active border router to reach anything beyond the mesh. Commissioning data survives a hardware reset on several implementations, so removal from the previous fabric has to happen before the reset, not after it.
Microphone: Carries a microphone with a hardware mute. A muted microphone is a physical switch state that no app setting overrides, and is the first thing to check for any voice or audio symptom.

Exact questions

Questions that only have an answer for the Nest Hub (2nd gen)

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

Where is the camera on the Nest Hub (2nd Gen)?+

There isn't one. This model has no camera — the Nest Hub Max does. Instructions involving video calls, camera gestures or a physical camera shutter are written for the Max, which is the most common source of confusion between the two.

How does it detect me if it has no camera?+

Soli, a radar sensor. It supports presence and gesture features without any camera, which is a genuine privacy difference from camera-based displays and also why the device can appear to see you when it cannot.

My Thread devices went offline when I unplugged the Hub.+

That is expected and it is the most important thing to know about this device. It carries a Thread radio and can act as infrastructure for Thread accessories, so removing, moving or replacing it can take other devices offline with it. It has no battery, so a power cut does the same.

Does it have a battery?+

No. It uses a DC power jack and a 15W adapter, so it stops with the power and comes back with it. Anything depending on it — including Thread accessories — stops too.

Can I use a different power adapter?+

Use the supplied 15W adapter. A DC jack that accepts a plug is not the same as a supply that delivers the right current, and an underpowered adapter produces restarts that read exactly like a failing device.

Does it work with Matter devices?+

Yes — it is Matter compatible and carries Thread, which is the combination that lets it act as a controller and a border router for Matter-over-Thread accessories rather than only as a display.

Structured depth, not empty permutations

Every published record carries a direct answer, scope, ordered fixes, risk notes and sources.

Device and manufacturer hubs share a consistent record system, but each answer carries the relevant controls, fault boundaries, consequences and official support entry point for that platform.
