Cloud or gateway? Why the combination is key for AI automation

The best solution for home energy management systems in practice combines both approaches

‍Introduction

Discussions about modern home energy management systems (HEMS) often focus on two technical approaches: should the control system be Cloud2Cloud or based on a local gateway? This question regularly leads to lively debates among experts. From the end customer's point of view, however, a different perspective is crucial: the system must function reliably - and for many years to come. From the provider's perspective, the product must support the business models - in essence, the question of whether an installation should be on site.

Instead of getting lost in fundamental technical issues, energy service providers should offer solutions that combine the advantages of both worlds. This is the only way to establish stable, efficient and future-proof systems in the long term.

Main part

An efficient HEMS should cover three essential functions:

A. Dynamic tariffs with live connection to the electricity exchange


By directly integrating current electricity market prices, energy consumption can be controlled flexibly and cost-effectively.

B. Optimized charging as a central use case


Demand-based control of the charging process is a key practical benefit, particularly in the field of electromobility. This function can often be realized without additional hardware installation via Cloud2Cloud connection of eCars or charging boxes via IP - a clear advantage for fast and uncomplicated implementation for all customer groups.

---> With these two components, a significant increase in efficiency can already be achieved without having to install additional devices on site.

C. Transparent metering systems for grid supply and feed-in

In order to enable complete optimization - for example in the event of PV surpluses - a metering system is required that can be retrofitted regardless of the manufacturer and can be flexibly supplemented with additional components such as battery storage, air conditioning systems or heat pumps. At this point at the latest, a gateway-centric model is recommended to ensure longevity, stability and expandability.

Summary

Cloud2Cloud and gateway solutions each have specific strengths and weaknesses. The most effective solution for a modern home energy management system is to intelligently combine both technologies and tailor them to the requirements of the respective target group.

In addition to the technical architecture, factors such as regional availability, reliable service and user-friendly operation also play a key role in market success.

Providers should therefore focus less on theoretical considerations and more on implementing concrete, functioning solutions - for the benefit of their customers and with a view to a sustainable, future-proof energy supply.
