My electric bill tells me what my house used last month. Sense shows me what my house is doing right now.
At my own home, the Sense Home app gives me a live view of total electrical demand. I can watch the number and graph change as equipment turns on and off. As Sense learns the recurring electrical patterns in the house, it also begins separating out different appliances so I can see more than one big monthly total.
That changes the meter from something I rarely thought about into a useful part of the home.
This is becoming relevant for more Massachusetts households because National Grid is replacing older electric meters with new smart meters. For eligible National Grid electric customers, the Sense Home app can connect to a compatible meter without adding a separate energy monitor inside the electrical panel.
What I can see at my house
The live view is the feature I use first. It shows the home’s current demand in watts and updates the graph second by second inside the Sense app.
That makes a simple experiment possible: look at the live total, turn something on, and watch what changes. The result is much more concrete than trying to interpret a single number on an electric bill weeks later.
The appliance view adds another layer. Sense learns the electrical signatures created when equipment starts, runs, and stops. Once it has identified a recurring pattern, I can see that device’s activity and how it contributes to the larger household load.
I do not treat every label as perfect. Device detection takes time, and Sense may not identify every appliance. Low-power electronics, variable-speed motors, overlapping loads, and complex equipment can be difficult to separate. Some appliances may appear as more than one component.
Even when a device does not have a clean name yet, the whole-home meter remains useful. I can still see that demand changed and investigate what was happening in the house at that moment.
A new option for National Grid electric customers
National Grid says it is installing more than 1.4 million electric smart meters across Massachusetts over several years. Sense access is rolling out gradually and requires compatible, up-to-date meter software.
National Grid determines eligibility. Eligible customers receive an email invitation from National Grid to connect Sense to their new smart meter.
National Grid currently says:
- The Sense Home app has no direct cost or subscription fee for an eligible National Grid electric smart-meter customer.
- The program is voluntary.
- It is for National Grid electric customers with a compatible smart meter—not simply anyone who has a National Grid gas account.
- A home needs secure, reliable Wi-Fi that reaches the meter.
- The Sense-enabled smart-meter option is not currently compatible with homes that have solar panels.
If the app does not accept an account yet, that may be a rollout or firmware limitation rather than a setup mistake. National Grid’s eligibility notice and the Sense eligibility checker are the right starting points.
The Wi-Fi connection matters
The meter may be outside, on a side wall, or at the edge of the property’s normal wireless coverage. A phone can appear to work nearby on cellular service while the meter itself still has a weak Wi-Fi connection.
Sense’s current setup instructions call for a password-protected 2.4 GHz network and recommend completing setup close to the meter. That can expose ordinary home-network problems: the signal does not reach outdoors, band steering confuses onboarding, the Wi-Fi name has changed, or a mesh point is in the wrong place.
Before changing the whole network, I would verify:
- The household has actually received the National Grid invitation.
- The phone is connected to the intended home Wi-Fi.
- The 2.4 GHz network reaches the meter reliably.
- The account number or phone number matches the National Grid account.
- A VPN, hotspot, or guest network is not getting in the way of setup.
- The Sense account and recovery details belong to the homeowner.
The goal is not merely to get through the pairing screen. The connection should remain stable after everyone walks back inside.
Turning visibility into useful automations
Sense is most valuable as a source of information. It does not make an appliance controllable just because it can see the appliance’s electrical pattern.
For a more capable smart home, Sense data can also be brought into Home Assistant. Home Assistant’s official Sense integration exposes whole-home power readings along with on/off and power sensors for devices Sense has detected.
That can support practical automations such as:
- Sending a notification when total household demand stays above an agreed threshold for several minutes.
- Reminding someone when a reliably detected appliance has finished running.
- Flagging unexpected energy use while the household is away.
- Adding live and historical energy information to a single home dashboard.
- Combining energy data with occupancy, temperature, or time of day before suggesting a change.
- Turning off a separate, safely controllable nonessential load after a deliberate delay and confirmation.
There are two boundaries I keep in mind.
First, the Home Assistant integration uses cloud polling. Its active power sensors are documented as updating about once per minute, so this is not a subsecond control system. It is suitable for dashboards, notifications, and tolerant household routines—not protective relaying or an emergency shutoff.
Second, any automation that switches power needs a separate rated control device and a safe failure plan. I would not automatically interrupt a refrigerator, freezer, sump pump, furnace, medical device, life-safety equipment, or high-current appliance based on one cloud reading. Monitoring can be broad; automatic control should be narrow and tested.
What TTCo can help with
Tyler’s Tech Company can help eligible National Grid electric customers in Greater Boston turn a Sense-enabled meter into something useful instead of leaving the app unused.
A typical setup can include:
- Checking the National Grid invitation and Sense setup requirements
- Installing and configuring the Sense Home app
- Checking 2.4 GHz Wi-Fi coverage at the meter
- Correcting mesh or access-point placement when the signal is marginal
- Reviewing the live meter and helping validate device discoveries
- Setting useful alerts without creating notification noise
- Connecting Sense to Home Assistant when appropriate
- Building conservative energy dashboards and automations
- Testing delays, failure conditions, and manual controls
- Documenting account ownership and recovery
National Grid controls meter eligibility and firmware; Sense handles the app account and product support. TTCo can make sure the home network and app setup are ready, explain what the data does and does not mean, and build the smart-home workflow around reliable information.
A few expectations worth setting
Sense starts with a live whole-home view. Appliance identification develops over time, and it will not necessarily produce a perfect inventory.
The app’s bill forecast is also an estimate. National Grid says it does not send individual billing details to Sense, so the forecast may use a statewide average rate unless the homeowner adjusts it. National Grid MyAccount and the actual utility bill remain the authority for billing.
National Grid also says it cannot see the energy data inside a customer’s Sense account. Sense handles that app data and support relationship. As with any connected-home service, the homeowner should understand the account, privacy settings, recovery method, and people who have access.
The bottom line
What I like about Sense is not that it adds another screen to my house. It makes electricity visible while there is still time to act on it.
I can see the live load, watch different appliances emerge, and connect those observations to useful questions: What changed? Is something running longer than expected? Is the house using a surprising amount while no one is home? Would a notification or a carefully designed automation make this easier?
For eligible National Grid electric customers in Greater Boston and across Massachusetts, that capability may already be arriving with the new smart meter. If you want help connecting it, improving Wi-Fi at the meter, understanding what Sense is finding, or using the data in a practical Home Assistant setup, Tyler’s Tech Company provides smart-home design and installation and whole-home Wi-Fi support throughout our Greater Boston service area.
