How does the Smappee Plus for households work?

The Smappee monitors measure energy use in real time using patented Smappee NILM (Non-Intrusive Load Monitoring) technology. Smappee Plus can also be used for submetering via the additional inputs, to which additional clamps can be attached. These additional inputs can individually measure and display subcircuits in the Smappee app. Submetering allows you to detect and monitor appliances with complex consumption patterns, such as those with a variable output (heat pumps and air conditioning units). Smappee Plus also regulates your energy resources. Too much solar power? Then allocate it to your water heater.

Smappee Plus must always be installed by a certified installer.

What is a Smappee Plus?

Smappee Plus is our smartest, most advanced energy monitoring system yet. For solar consumers, Smappee Plus adds submetering capabilities, allowing users to recognize specific home appliances that were previously difficult to detect with our Smappee Solar product. Now, appliances with variable consumption, such as an air conditioning unit, can be automatically recognized and logged into Smappee’s smart home energy-efficiency data.

But that’s not all.

Smappee Plus can aggregate valuable insights about how much users are spending on specific energy usage in their home. Users of Smappee Plus can see how much they’re spending on such things as lighting, or their pool pump, or a specific room in their home — empowering them to make informed, purposeful decisions about saving energy as well as costs on their monthly electricity bills.

Smappee Plus also acts as an energy traffic controller. Rather than receiving a lower net metering bill credit, Smappee Plus can direct solar kilowatt-hours to an energy storage unit or to high-intensity loads, such as a dishwasher, during expensive peak rate times. Therefore, not only will solar consumers have more energy bill insights about the usage of their appliances, they’ll also increase their savings during high demand rates.

As with all Smappee models, Smappee Plus also works with Smappee Comfort PlugsTM, allowing users to remotely control and monitor lights and appliances at work or at home.

How to install multiple Smappee monitors under 1 user account

To install multiple Smappees on one account, you will need to create an additional (new-home for each SMappee. This means that you will have access to all these homes. This means that you will have access to all these homes (locations) by logging into that one account.
  • To add a new location, tap on ‘Profile’ on the right bottom of the screen.
