FAQs About Smart Energy Monitoring

Find answers to the most common questions about using smart energy monitors at home or in your business. Whether you’re installing your first device or optimizing a solar-powered system, this section will help you get the most out of your Grus setup.

What is a smart energy monitor, and how does it work?

A smart energy monitor is a device that tracks your home’s or building’s electricity usage in real time. Grus devices like WattPanel-2X or WattNet-3 connect to your electrical panel and use clamp sensors to measure power flow through individual circuits or the entire system. Data is sent to the Grus Home Energy App, where you can view usage patterns, receive alerts, and analyze trends.

What’s the difference between a Grus smart meter and a utility smart meter?

While utility smart meters track your overall consumption for billing, Grus smart energy monitors provide real-time, circuit-level insights directly to you. You can:

• View which devices use the most power

• Detect wasteful standby loads

• Optimize based on peak/off-peak hours

• Monitor solar input (with compatible setup)

Do I need an electrician to install it?

For most Grus smart energy monitors, especially WattPanel-2X and WattNet-3, we recommend professional installation due to the need to access your main electrical panel. However, users with electrical experience can refer to our step-by-step guides and safety recommendations in the support center.

Can Grus energy monitors work with solar systems?

Yes. All Grus energy monitors are solar-ready. You can monitor solar production vs. household usage, set net metering alerts, and optimize for self-consumption. The WattNet-3 is particularly suited for three-phase solar setups.

Will it work with smart home systems like Google Home or Alexa?

Yes. The Grus App integrates with major smart home platforms, including:

• Amazon Alexa

• Google Assistant

• Apple HomeKit

• SumSung SmartThings

• Home Assistant

You can ask your voice assistant:

“What’s my current energy usage?”
“How much power did I use yesterday?”
“Is the garage light still on?”
Can I monitor individual appliances?

Yes, using circuit-level tracking, you can monitor groups of devices (e.g., kitchen, HVAC, home office). For appliance-level precision, we recommend pairing your energy monitor with smart plugs or sub-circuit sensors, available as accessories.

How secure is my energy data?

Grus encrypts all data in transit and at rest using industry-standard protocols. Your information is never sold and can be fully deleted at your request. You retain complete control of your data through your account dashboard.

The Data Server is located US or Europe based on your location.

Can I export my data?

Absolutely. You can export detailed CSV reports by hour, day, or month directly from the Grus App (Individual user) or Web Dashboard(for business usage). Perfect for budgeting, audits, or utility rebate applications.

Customer Success Stories

Discover how real users are leveraging Grus smart energy monitoring to save money, reduce waste, and gain control of their home or business energy use.

Case 2:

Ontario Warehouse Saved Thousands by Shifting Peak Loads

A 6,000 sq ft warehouse in Ontario installed WattNet-3, Grus’s industrial-grade 3-phase energy meter, to gain visibility over their equipment usage and power demand cycles.


Before the installation, the facility:

• Operated heavy machinery during peak tariff hours

• Had no visibility into HVAC cycling or refrigeration loads

• Encountered power penalty surcharges from utility due to demand spikes


Using the Grus Customized Dashboard + historical reports:

• They mapped energy consumption per hour across a 30-day window

• Discovered their CNC machine startup at 8:00 AM caused massive demand surges

• Rescheduled non-critical systems to start in staggered intervals

• Upgraded lighting to LED after identifying inefficient legacy fixtures

✅ Results:

• Reduced peak demand by 22%

• Avoided ~$1,800 in peak pricing surcharges over 4 months

• Qualified for a local utility rebate for load-shedding improvements


💬 Operations Manager:
“Grus gave us data-backed decisions. We stopped guessing and started saving—our utility bill is now a strategic tool, not a surprise.”


Case 1:

Emily from California Cut Her Power Bill by 27% in 3 Months

Emily, a homeowner in sunny San Diego, used to receive monthly electric bills exceeding $180, especially during peak air conditioning season. Curious about her energy use, she installed the Grus WattPanel-2X to track individual circuits throughout her home.


Within a week, she uncovered that her always-on pool pump and underutilized basement dehumidifier were responsible for 35% of her daytime consumption.


Using the Grus Home Energy App, Emily:

• Set timers to control high-draw devices

• Scheduled major appliances (washer, dryer) for off-peak hours

• Identified phantom loads (devices drawing power even when idle)

✅ Results:

• Reduced electricity bills from ~$180 to ~$131/month

• Shifted 41% of her consumption to off-peak hours

• Received smart alerts during energy spikes (e.g., oven left on)

💬 Emily says:
“The WattPanel showed me how much energy we wasted every day — I’ve taken back control and saved over $140 in just three months!”
