Dynamic Assistant is seamlessly integrated into Viessmann Energy Management or the basic version of Energy Management. It optimises the interaction between all electricity-generating, electricity-storing and electricity-consuming devices in the system, particularly with regard to electricity prices. In addition, the aim is to keep self-consumption and self-sufficiency high in order to minimise your electricity costs as much as possible.
Automatically lower your electricity costs with intelligent optimisation through Dynamic Assistant. Dynamic Assistant is a ViCare subscription available in two versions. Depending on your system configuration and the connected devices, one of the two versions will be recommended for you. With this ViCare add-on, your electricity consumption from the grid automatically adapts to price fluctuations — with no manual effort required. Activate Dynamic Assistant in your ViCare app under the “Discover” tab.
Dynamic Assistant and Dynamic Assistant PRO can be tested free of charge for 6 months.
Why should I use Dynamic Assistant?
The ideal home energy system only draws electricity from the grid when it is abundant or very cheap.
-
Save Electricity Costs
Reduce your electricity costs by using power from the grid when energy prices are lower.
-
Maintain climate comfort
Enjoy optimal climate comfort at home at all times, without manual adjustments.
-
Automated solution
Our algorithms work for you without you having to worry about a thing.
The difference between Dynamic Assistant and Dynamic Assistant PRO
ViCare automatically recommends the version that best suits your system, so you can make the most of your energy system’s savings potential.
Dynamic Assistant
Dynamic Assistant is designed for installations with only a heat pump and includes tariff-based optimisation. It only requires the basic version of Viessmann Energy Management and is available at a lower subscription price. As the optimisation options are more limited, the potential savings are generally lower than with larger systems that include more devices to optimise. The cost is £2.99 per month or £29.99 per year, depending on the selected billing model.
Dynamic Assistant PRO
Dynamic Assistant PRO is designed for energy systems with additional components such as energy storage systems or charging stations for electric vehicles. It requires Viessmann Energy Management to have been commissioned by a qualified specialist partner. Tariff-based optimisation includes advanced functions such as charging the battery from the grid and Smart Charging for electric vehicle charging stations. These additional optimisation options can help achieve higher savings. The cost is £5.99 per month or £59.99 per year, depending on the selected billing model.
* Dynamic Assistant PRO: If the energy system consists of more than just a single Vitocal heat pump — for example, a Vitocal, a Vitocharge VX3 and/or a charging station — and is to be optimised with Dynamic Assistant PRO, a Viessmann CAN bus energy meter (E380CA-2 AR-N) is required at the grid connection point as a requirement for Viessmann Energy Management.
How electricity cost optimization works
The Dynamic Assistant optimizes the electricity consumption of your entire home energy system. Every day, the algorithm identifies the most favorable time slots and plans the various running times of your devices, such as heat pumps and electricity storage systems, taking into account the weather forecast.
Supported devices in the Viessmann System
-
Vitocal heat pump
Dynamic Assistant optimizes the running times of your heat pump while maintaining consistent climate comfort in your home.
-
Vitocharge power storage system
Dynamic Assistant optimizes the charging of your electricity storage system from the grid at favorable times, in addition to using your own photovoltaic electricity.
-
Charging station for electric cars
Dynamic Assistant optimizes the charging of your electric car via the wallbox by shifting it to low-price periods (available from the end of 2025).
Requirements for optimization
There are a few things to keep in mind to ensure that optimization with Dynamic Assistant runs smoothly.
A smart meter is an electricity meter that records your electricity consumption in real time and transmits it to your energy supplier via the internet or mobile network.
Unlike conventional electricity meters, which only record total consumption and are read manually, a smart meter records your energy consumption in 15-minute intervals. This detailed consumption data is securely and automatically transmitted to your energy supplier.
