HEMS app: Everything at a glance

Full transparency about your energy system? You can find it in the Leaflet HEMS app. The future of home energy management. Discover it now!

Simple, compact, and clear. That's how we imagine an energy management app should be. And that's why we make it that way! Today, we'll walk you through our HEMS app step by step, from downloading to evaluation.
 

Step 1: Installation.

It all starts with installing the Leaflet HEMS. A specialist company installs the Energy Manager in the sub-distribution board (electrical box) of the house. Then you can download the HEMS app. Here you will find downloads for all common operating systems: Download the HEMS app!
 
Best of all, the HEMS app is free. Don't have Leaflet HEMS yet and want to try out the HEMS app first? Sure thing: just download the app and continue in demo mode.
 
The practical installation wizard helps the specialist company with the next steps. Once everything is correctly wired and connected in the Leaflet HEMS, the HEMS app automatically detects devices and requests the necessary settings for optimization. With just a few taps, the entire energy system is set up in the HEMS app.

Step 2: Live view and functions.

Whether at home or on the go, with the HEMS app you can always track energy flows in your home in real time. The dashboard clearly displays the last 24 hours. You can see
  • ... how much electricity the PV system produces (yellow),
  • ... how much electricity the system draws from or feeds into the grid (blue),
  • ... how much electricity heat pumps (orange), wall boxes (turquoise), battery storage systems (green), etc. consume.
 

The Leaflet intelligently controls these consumers according to the desired specifications. The following functions are currently available.

PV-optimized heating:

The heat pump is controlled via the SG-Ready interface in such a way that existing PV surplus is utilized as optimally as possible.

Intelligent charging modes:

  • Next trip: Charging mode is used to reach a specific charge level by a departure time and to plan charging so that as much of your own solar power as possible is used.
  • Solar power only: The vehicle is automatically charged with solar power as soon as sufficient surplus is available.
  • Always charge: Charge mode ensures that the vehicle is charged with the maximum available charging current.

Step 3: Evaluations.

The app provides lots of statistics that allow you to clearly track your energy consumption, feed-in, and consumption values.
 

The energy balance shows at a glance how energy consumption was covered (via PV self-production, battery, grid purchase) and when feed-in took place.

The consumption history shows the energy consumption of individual devices throughout the day.

The totals show the values for consumption, production, grid consumption, and grid feed-in for each day.
