Powersensor Monitor

The DIY, Solar-Compatible Energy Monitor

Powersensor is an Australian-designed electricity monitoring system. It will help you understand and reduce your energy usage. If you have solar panels installed, it will help you get the most out of them.

Easy Do-It-Yourself Installation. No electrician or tools are required.

Realtime Updates. Get instant access to your energy data.

Energy Insights. Uncover precisely when and how much power you use and produce. Explore historical data by hour, day, week, or month.

Detailed Cost Tracking. The Powersensor app allows for complete entry of your electricity rates, including the supply charge, solar feed-in tariff, and much more.

Expandable. Add up to eight additional Plugs and Sensors.

The app includes a detailed and easy-to-follow set-up guide. You'll be up and running in about 15 minutes.

Choose Your Kit: Energy or Solar

Powersensor comes in two main configurations:

Energy

Choose this model if you don't have solar or if you do have solar but with multiple inverters. When solar is present, this solution reports NET energy usage and solar export only.

Solar

Choose this model if you have solar panels installed and a single solar inverter. This solution allows for detailed solar tracking, including total production, self-consumption, and more.

Check if You Have Single, 2 or 3 Phase Power

At your electricity meter-board or switch-board, take a look at the 'Main Switch.' You can verify which type you have using the image below as a guide.

Single Phase (single-pole) main switch on the left vs. a 3 Phase (three-pole) main switch on the right. 2 Phase power is less common and has a two-pole switch.

How Powersensor Works

The Powersensor energy monitoring system has four main parts.

The Sensor, Optical Reader (three-phase only), Plug, and App.

The Sensors are wireless devices that you install at your meter-board and solar inverter (if present). They use a patented technique to measure electricity flow without directly contacting any wires.

The Optical Reader detects any digital electricity meter's pulse output (flashing red light). It helps to calibrate the primary sensor at three-phase sites only.

The Plug measures the power usage of a key appliance and helps calibrate the main sensor at single-phase sites. It also acts as a wireless 'gateway' relaying data from the sensors to the internet via your WiFi network.

The App provides instant access to your data, whether you're at home or away. The app includes both energy and cost tracking.

Powersensor Parts

Depending on which model you choose, you'll receive the following parts. Regardless of your chosen configuration, the app will guide you through the simple DIY installation process.

Model	Single Phase	2 or 3 Phase
Energy	1 x Plug 1 x Sensor	1 x Plug 1 x Sensor 1 x Optical Reader
Solar	1 x Plug 2 x Sensors	1 x Plug 2 x Sensors 1 x Optical Reader

 

The above is a simplified overview of the Powersensor kit contents. You'll receive everything you need to complete installation, including:

• USB cables to recharge the sensors once every year or two.
• High-quality 3M Dual Lock velcro pads to secure the sensors in place.
• A custom mounting bracket for three-phase properties.
• Instructions and a QR code to download the app.

Frequently Asked Questions

How many extra plugs or sensors can I add? 

You can add up to eight extra sensors or plugs to track individual appliances or loads.

Can I upgrade and expand my kit?

Yes. You can upgrade an Energy system to a Solar system by adding a sensor for your solar inverter later on. Add an Optical Reader required for three-phase installations if you started with a single-phase system.

I'm not sure if I have Single, Two, or Three Phase power.

Please read our blog post on how to tell if you have three-phase power.

Is this a remotely accessible energy monitor?

Yes. Once set up you can check your energy usage from home, at the office, or anywhere in the world.

Is it compatible with multiple solar power inverters?

Yes. But you must choose the Energy solution for this. Rather than tracking multiple inverters individually (which is not possible), it simply tracks the NET import and export of power from your main switch-board.

How often does the data update?

The app's readings update every 30 seconds.

Where can I download the Powersensor App? Is it free?

Yes - your purchase of the device covers the cost of the app. Here are the download links for any Apple or Android:

Powersensor does not charge ongoing fees and has not done so for the past five years. However, they may release even more features as an optional extra.

Can I export or download my consumption and solar energy data?

Yes. The app includes a data export function (to a .csv spreadsheet file). Data is stored half-hourly and includes kWh, peak kW and cost values for energy from-Grid, to-Grid, Solar, and Net.

When is Powersensor NOT recommended?

There are a few specific situations where the Powersensor system will not be compatible with your setup. These include:

Apartments or Units. Most multi-dwelling buildings are not suited to Powersensor, unless your main meter-board is fully accessible by you and within 10 metres of your home.

Home Battery Systems. Powersensor does not currently work with home batteries, but they hope to add this functionality in the future.

3 Phase With Multiple Electricity Meters. If you have three-phase power and multiple electricity meters - whether digital or analogue - Powersensor is not compatible. On the other hand, single-phase sites with multiple meters are acceptable because the single-phase system does not use the main meter for calibration.

On-Billing or Sub-Metering. If you want to on-bill a subtenant, use a hard-wired sub meter instead.
