Connectivity and platforms: Innovative solutions for the connected world

Allendorf (Eder), may 6, 2021 – Connectivity and platforms are becoming an increasingly important part of Viessmann’s Integrated Solution Offering. By seamlessly networking energy systems with digital services, specialist partners can offer their customers new services, such as remote maintenance and remote parameterization of heating systems. Digital platforms, such as wibutler, also enable cross-trade smart home solutions.

The new products at a glance

• The new Viessmann Energy Management system makes energy flows in the home transparent and enables them to be used in a resource- and cost-saving way.
• The vendor-neutral wibutler Smart Home Platform now communicates with all other ViCare components: from the ViCare radiator thermostat to the ViCare climate sensor. In addition, the integration of the latest generation of Vitodens wall-mounted gas boilers has now been successfully completed.

Viessmann Energy Management for the efficient operation of all components

Conserving resources and saving costs by way of the energy-efficient, optimized operation of all electrical and thermodynamic-electrical energy systems in the home – this is the strength of the new Viessmann Energy Management, which is optionally integrated in the new electronics platform and can be made available to customers via the  ViCare  app without additional accessories. Aside from controlling components, the Energy Management groups connected devices such as Vitocal heat pumps, the  Vitocharge VX3  electricity storage system and thermodynamic DHW cylinders together online to form an overall system. Users are thus provided with a functional system management concept for optimal operation. In this way, many system components in the home can be controlled in a resource-conserving and energy-efficient manner.

All energy flows at a glance

Viessmann Energy Management displays energy flows in the building in real time on a smartphone or tablet. This includes, among other things, values of self-generated electricity from the photovoltaic system, as well as self-consumed electricity, for example, for the operation of the heat pump. In particular, Viessmann Energy Management provides these functions for the Vitocharge VX3 electricity storage system, the heat pumps of the new Vitocal 25x-A series, as well as the heat pumps in existing buildings with  Vitoconnect  up until 2016.

Prepared today for tomorrow’s components

Energy Management is an interactive tool in the Viessmann product world. It follows the familiar solutions for commissioning and monitoring an energy system for specialist partners, as well as the same solution for visualization and control in the app environment for customers.

The charging of e-cars, taking into account weather data, the status of the vehicle battery and photovoltaic power generation according to user preferences, will be able to be optimized from the end of 2021 onwards. Users will be able to choose whether to use only self-generated electricity from the photovoltaic system or the fuel cell heating device, or to charge additionally with energy from the power grid.

GridBox 2.0: Intelligent control of wallbox for electric vehicles

Exploiting self-generated electricity and reducing the use of expensive mains current as far as possible – the  Viessmann GridBox  intelligently manages power generation, storage and consumption to increase the consumption of self-generated electricity. As the central platform for connecting the photovoltaic system, electricity storage system, electric heat generation and a charging station for an electric vehicle, it optimizes energy flows and ensures transparency. It also forms the basis for achieving the KfW 40 Plus standard and obtaining the associated subsidy of up to EUR 30000 per residential unit.

Increasing consumption of self-generated electricity with new optimization functions

The GridBox’s new optimization functions for the photovoltaic system, electricity storage system, DHW generation and wallbox for electric vehicles now make it possible to increase the consumption of self-generated electricity even further. In addition, users can prioritize utilization of self-generated photovoltaic electricity via the dashboard. For instance, they can specify what to charge first with the solar power: the electricity storage system or the rechargeable batteries of the electric vehicle. Rules regarding vehicle charging can also be defined.

The GridBox can also use surplus electricity from solar to operate a modulating heater inside the DHW cylinder, thus preventing it from feeding into the public grid. Any electricity that isn’t required at that moment can thus be stored thermodynamically for subsequent use for bathing, showering or cooking.

An overview of all-electric heat generators at all times

The online dashboard visualizes all of the power generators and consumers connected to the GridBox, as well as the electricity storage system and wallbox. Users thus have quick access to a compact overview of daily trends, weather forecasts, weekly reports, CO₂ monitoring and tips to save energy. What’s new is the visualization of all-electric heat generators such as  Vitoplanar  infrared heating systems in the individual rooms.

New mygridbox app for convenient monitoring on the go

All of the functions of the GridBox Dashboard are now also available in the new mobile app for Android and iOS smartphones. Power generation, storage and consumption can thus also be conveniently monitored and managed on the go.

Simple installation

The GridBox is simply connected to the electricity and the router or a switch (switch/MAC bridge). Following the setup process, which only takes a few minutes, it automatically scans the household for connected devices.
