Future Trends and Forecast until 2030

By 2030, smart meters will increasingly evolve into intelligent energy management hubs. The combination of metering, control, and AI-based consumption analyses will become standard. Devices with their own edge intelligence, as already seen in initial versions from Janitza and Shelly Pro, will become central interfaces in the decentralized energy market.

In parallel, the trend towards "Open Energy Devices" – modular devices with freely programmable firmware – is developing. This will offer end customers more flexibility and independence from proprietary clouds.
