Most people buy the doorbell first. That is the mistake.
A video doorbell is the cheapest, easiest, most giftable smart device on the shelf, so it ends up being the front door to a whole-house project that was never planned. Six months later you own four apps, three hubs, a router that coughs when the dryer kicks on, and a hallway light that turns on at 2 a.m. for reasons nobody can explain.
You can skip all of that. The fix isn’t better gadgets. It’s a better order of operations. Plan the wiring and the network before you plan the devices, bring in smart home technology installers in NH for the parts that touch your electrical system, and the rest becomes a series of small, reversible decisions you can make on a Saturday afternoon. Here’s how I’d sequence it if it were my own house in Concord or Gilford.
Start with the boring layer nobody wants to talk about
Every smart home sits on two invisible foundations: power and network. Get those wrong and no amount of well-reviewed hardware will save you.
Power means switch boxes with a neutral wire where you need one, outlet locations that make sense for where you’ll actually mount things, and circuit capacity for whatever you add later. A lot of older New England homes have wiring that predates any of this, which is why the electrical conversation comes first. The National Institute of Standards and Technology publishes voluntary frameworks for connected devices, and the one point worth pulling out of that work is that interoperability is a design problem, not a shopping problem. It gets solved at the planning stage or not at all.
Network means coverage, not speed. A single router in a finished basement will not reliably reach a camera on the far side of a two-story colonial with plaster walls. Walk your house with your phone, watch the Wi-Fi bars, and note the dead zones before you buy anything that needs to stay connected.
How do you choose a hub without locking yourself in?
Pick the protocol before the products. This is the single decision that determines whether you’re still happy in five years.
There are three flavors worth knowing. Matter and Thread are the newer cross-brand standards designed so devices from different makers can talk to each other. Z-Wave and Zigbee are older mesh protocols with deep device catalogs and a long track record. Wi-Fi devices are the simplest to set up and the worst at scale, because every one of them competes for the same airtime.
My take: build around Matter and Thread where you can, use Z-Wave for anything you want to run on battery for a year, and limit Wi-Fi devices to the handful that genuinely need cloud features. You’ll thank yourself the first time you swap a hub.
One more thing people skip. Decide now whether you want local control or cloud control. Local keeps working when the internet drops. Cloud gives you remote access and better voice assistant integration. Most homes end up wanting both, which means you need a hub that supports both, and you need to know that before the electrician is standing in your hallway.
The upgrade order I’d actually follow
Here’s the sequence, ranked by how much each step improves daily life per dollar spent.
- Thermostat. Highest return, lowest complexity, and it’s the one device everyone in the house notices immediately.
- Lighting. Smart switches beat smart bulbs in almost every room except lamps. Switches keep working when someone flips them by hand.
- Network. Add a mesh node or two before you add cameras. Cameras are bandwidth-hungry and unforgiving.
- Security. Cameras, door sensors, and a doorbell, once the network can carry them.
- Water and energy monitoring. Leak sensors and a whole-home energy monitor, which is where the real money hides.
- The fun stuff. Voice control, scenes, automations, motorized blinds. Do this last, not first.
The temptation is to start at step six. Everyone does. Fight it.
What the smart home upgrade actually costs
Device prices are easy to look up. The numbers that surprise homeowners are the labor and the wiring, so let’s put rough shapes on those.
| Layer | Typical scope | What drives the price |
|---|---|---|
| Thermostat | One device, one location | Whether a common wire exists |
| Smart switches | Per room, 1 to 4 switches | Neutral wire presence, box depth |
| Network | Router plus 1 to 3 nodes | House size, wall materials |
| Cameras | 2 to 6 locations | Power runs, cable paths, exterior mounting |
| Energy monitoring | One panel location | Panel access and available space |
Rough rule: the electrical work is where budgets move most, because it depends on what’s already inside your walls. The Department of Energy has long noted that connected devices can help households understand and reduce consumption, but that only happens if the monitoring is installed correctly in the first place. A miswired energy monitor is worse than none, because it lies to you.
The retrofit problem, and how to spot trouble early
New construction is easy. You plan conduit, you pull wire, you’re done. Existing homes are a negotiation.
Watch for four warning signs before you commit to a plan. Switch boxes too shallow for smart switches, which is common in homes built before the 1980s. No neutral wire in a lighting circuit, which rules out most smart switches without a rewire. A panel with no spare breaker slots, which blocks energy monitoring and any new dedicated circuits. And plaster or brick walls that eat Wi-Fi for breakfast.
None of these are dealbreakers. All of them change the estimate.
This is the part I’d outsource rather than improvise. Anything behind a switch plate or inside a panel is a licensed electrician’s job in most jurisdictions, and the Institute of Electrical and Electronics Engineers maintains the electrical and electronics standards that inform how this equipment is designed and tested. That’s not a reason to be nervous. It’s a reason to have one qualified person walk the house and tell you the truth about what’s inside the walls before you buy a single device.
Your pre-purchase checklist
Run through this before you spend anything. It takes about an hour and saves a lot of returns.
- Walk the house and map Wi-Fi dead zones.
- Count the devices you expect to connect. Multiply by three for future additions.
- Photograph the inside of your electrical panel with the cover off, if you’re comfortable, or have someone do it.
- Test one switch box in each room for a neutral wire.
- Decide on your hub protocol and write it down.
- Set a budget split, roughly 60 percent hardware and 40 percent labor, and adjust from there.
- Confirm whether you want local control, cloud control, or both.
If you get through that list and still have questions, you were never going to get answers from a product page anyway.
Where this lands
The homes that end up with smart systems people actually like have one thing in common. Someone thought about the wiring and the network before the boxes arrived. The gadgets are the easy part and the least important part.
So start at the panel, not the porch. Get the foundations right, pick your protocol on purpose rather than by accident, and bring in a licensed electrician for anything that lives behind a switch plate. Then buy the doorbell.
Ask yourself one question before your next purchase: if the internet went out for a week, what in your house would still work?
