💡 What exactly is a smart meter?

Smart meters are the most advanced electricity meters in Germany.

They look similar to digital meters (both have a digital display), but smart meters come with an extra component: the smart meter gateway.

🔌 What does the gateway do?

The smart meter gateway is a communication device – often built into the meter or mounted on top.

It automatically and securely transmits your consumption data to your electricity supplier – no manual readings needed.

The best part?

You can track your energy use with hourly data via an app or online platform, helping you better understand and adjust your energy consumption habits. 🔍📉

🔎 How can I tell if I have a smart meter?

Here are a few key indicators:

• Your meter readings are automatically sent to your electricity supplier
• You can spot a BSI-certified smart meter gateway (usually mounted on the meter)
• Your household has a high electricity usage (6,000 kWh/year or more)

➡️ If any of the above apply, you most likely have a smart meter.

📊 Who gets a smart meter?

According to German regulations, smart meters are mandatory for:

• Households with an annual electricity consumption above 6,000 kWh
• Households with a solar system over 7 kW peak

👉 If your usage is lower and you don’t have a larger PV system, it’s unlikely that you currently have a smart meter.
