Before You Buy — What Nest Actually Requires

The right app: Google Home, not Nest

All current Nest hardware sets up and lives in the Google Home app. The legacy Nest app still exists but won't recognize new devices. Download Google Home, sign in with the Google account you want as the Home owner, and create a Home before touching any hardware.

Power varies by device

• Nest Doorbell (wired, 2nd gen): Requires existing 16–24V AC doorbell wiring. Check your transformer before purchasing — if it outputs less than 16V, you'll need a replacement ($15–30).
• Nest Cam battery: No wiring needed. Goes anywhere. Add the optional solar adapter for locations with sunlight and you'll rarely charge manually.
• Nest Cam Indoor Wired (3rd gen): Plugs into a standard outlet.
• Nest Learning Thermostat: Powered by your HVAC wiring. Requires a C-wire (common wire) for reliable operation — check for one on your existing thermostat before purchasing. The Nest Power Connector solves this if you don't have one.
• Nest Hub Max: Standard outlet. The simplest setup in the Nest lineup.

Nest Aware — the honest subscription picture

Without a subscription, cameras have only 3-hour event history — a clip from this morning is gone by evening. For any real security use, you need at minimum Nest Aware ($8/month or $80/year): 30-day event history, familiar face detection, and package alerts — for all cameras on the account, regardless of how many you have.

Nest Aware Plus ($15/month or $150/year) adds 60-day history and 24/7 continuous recording for wired cameras. If you have a wired doorbell, continuous recording is genuinely useful — it captures what happened between motion events. Thermostats and the Hub Max don't require any subscription.

Wi-Fi fundamentals

Every Nest device is Wi-Fi only — no ethernet option for cameras or thermostats. Two things to check before installing anything:

• AP isolation must be OFF on your main network. This setting prevents devices on the same Wi-Fi from talking to each other, which breaks Google Home device discovery.
• Signal at each device location matters more than your overall router speed. Test with your phone at the planned mounting spot before drilling.

Installing the Nest Doorbell (Wired, 2nd Gen)

Check your transformer first

Find your doorbell transformer (usually near the electrical panel, in a utility closet, or in the attic) and verify it outputs 16–24V AC. Lower voltage won't power the doorbell reliably. Replacement transformers are $15–30 and a straightforward swap. Skip this step and you may spend an hour on the physical install only to find it won't power on.

The physical install

1. Turn off the doorbell circuit breaker before touching any wiring.
2. Remove the old doorbell button. Two screws, usually. Disconnect the two wires — tape them so they don't fall back into the wall.
3. Use a wedge if needed. The doorbell comes with angled wedge mounts. Use one if your door is recessed or the doorbell would sit at an angle to the approach path. Skip it if it faces straight-on.
4. Thread wires through the mounting plate and screw it to the wall.
5. Connect one wire to each terminal on the back of the Nest Doorbell — no polarity, either wire to either terminal.
6. Snap the doorbell onto the mount and tighten the security screw at the bottom.
7. Restore power at the breaker.

Setup in Google Home

Google Home → + → Add → Set up device → New device. The app scans, finds the doorbell, and walks you through Wi-Fi credentials, naming, and room assignment. It flashes orange while connecting, then solid green when online. Let the firmware update finish before testing — usually 2–5 minutes.

If the indoor chime doesn't ring after setup: check Settings → Chime type (mechanical vs. digital). Some digital chimes need the Chime Connector (included in the box) wired at the chime unit — the app setup guide walks through this step.

Getting Nest into Apple Home

Google Nest doesn't natively support Apple HomeKit. The bridge that makes everything work is Starling Home Hub — a small hardware device (USB form factor) that runs locally on your network and presents every Nest device as a native HomeKit accessory. This covers cameras, thermostats, temperature sensors, and smoke detectors.

What works in Apple Home via Starling

• Live camera view in Home app and Control Center widget
• Motion, person, vehicle, and animal detection as HomeKit motion sensors
• HomeKit automations triggered by camera motion
• Siri camera control: "Show me the backyard camera," "Show me the front door"
• Full thermostat control: set temperature, mode, view current temp — "Hey Siri, set the living room to 70 degrees"
• Temperature sensors as HomeKit temperature accessories for automations
• HomeKit Secure Video (requires iCloud+ storage plan)

What still requires Google Home

• Nest Aware subscription management
• Familiar face detection and package alerts
• 24/7 continuous recording access and clip downloads
• Camera settings (activity zones, sensitivity, chime)
• Thermostat schedule editing and Eco temperature settings

Starling setup in 4 steps

1. Plug Starling Home Hub into USB power anywhere on your network. It broadcasts a temporary Wi-Fi for first-time setup.
2. Go to home.starlinghome.io from any browser on your network. Sign in with the Google account that owns your Nest devices.
3. All your Nest devices appear in the dashboard. Select which ones to expose to HomeKit.
4. Tap "Add to Apple Home," scan the QR code with your iPhone, and your devices appear in the Home app immediately.

What's next

This covers the foundation. The full guide goes deeper across 14 chapters in four parts: camera coverage planning and placement strategy; Nest doorbell install in full detail; outdoor battery cam positioning and battery life; indoor camera privacy features; Nest Aware subscription breakdown; activity zone configuration; thermostat C-wire setup and Auto-Schedule; temperature sensor multi-zone control; Nest Hub Max as a household command center; HomeKit Secure Video; automations for both ecosystems; and the complete room-by-room setup with everything I'd do differently.
