Reading your electricity meter via app – it's easy!

Read your electricity consumption digitally – your energy consumption on your smartphone

Making electricity consumption visible used to be cumbersome: notes, manual readings, inaccurate estimates. But that's changing – because today you can easily read your electricity meter via an app.

What sounds like the future is already a reality: With the right technology, your consumption data is digitally recorded and transmitted to your smartphone in real time. This way, you always have an overview of your energy consumption – whether in a rented apartment, your own home, or a smart home.

The advantages are obvious: greater transparency, fewer surprises on the electricity bill, and the opportunity to save electricity in a targeted way. Because those who know their consumption can also optimize it.

More and more households in Germany are using digital tools to reduce their energy costs and live more sustainably – conveniently and without any technical expertise. This article explains how it works, what you should pay attention to, and how you can digitally read your own electricity meter in just a few steps – including an introduction to the Stromleser app.

Why should you read your electricity meter via app?

Reading your electricity meter via app – it sounds futuristic, but it's incredibly easy to do today. Modern electricity consumption monitoring solutions offer numerous advantages – whether you want to reduce your electricity costs, track down energy guzzlers, or simply have a better overview.

The advantages are obvious:

• More overview : You can see live how much electricity you are currently using – directly on your smartphone.
• More control: No more estimates – instead, exact consumption data in real time.
• Greater savings potential: With the help of integrated analysis functions, you can specifically identify optimization potential and sustainably reduce your energy consumption.
• Greater sustainability: Those who use electricity consciously not only protect the climate, but also their own wallet.

Typical energy guzzlers in everyday life

Regular consumption analyses help you identify energy guzzlers that otherwise consume energy unnoticed. These include, for example:

• Old refrigerators and freezers with high energy consumption
• Standby devices such as televisions, routers or game consoles
• Instantaneous water heaters or electric heaters
• Washing machines and dryers with long cycle times
• Continuous operation of aquariums or pump systems

The Stromleser app – digital electricity measurement made easy

One solution that offers you all these advantages is the stromleser app. This is a mobile application for digitally reading your electricity meter. In combination with a stromleser reading head, you can read your electricity consumption in real time – simply, securely, and without any technical expertise.

There are two compatible devices to choose from:
The stromleser.tasmota is based on the open-source firmware Tasmota and transmits real-time data directly from the user interface. The stromleser.one uses its own proprietary firmware and additionally offers automatic storage and analysis of past consumption data directly within the app.

Both versions can be easily connected to the app – you can find more information directly in our shop.

Who is the Stromleser app suitable for?

The Stromleser app is ideal for anyone who wants to record and better understand their electricity consumption in real time – regardless of whether they live in a rented apartment, own their own house, or want to optimize their smart home.

Typical use cases include, for example:

• Owners and tenants who want to permanently record, compare and optimize their electricity consumption
• Users of balcony power plants who want to transparently track feed-in and self-consumption
• Smart home enthusiasts who want to seamlessly integrate their meter into an existing system

Setup: How to connect the power meter app to your device

The initial steps in the stromleser app are identical for both stromleser tasmota and stromleser.one . Only after that does the setup differ – depending on which device you are using.

Joint steps

1. Download the app
Download the app "stromleser – Energie im Blick" from the App Store or Google Play Store down.

2. Registration
Create a user account:

• Either via your Google or Apple account
• Or the classic way, via email and password.
• Verify your email address using the confirmation code sent to you.

3. Open the app and select the power reader tile.
Open the app and tap on the "stromleser" tile.
From here on, the next steps differ depending on which device you are using:

Note: The Stromleser app displays all the data that your digital meter provides via the D0 interface. Depending on the meter model, a PIN may be required to access certain data fields – you can find more information here .

Two paths – one goal

Whether you choose stromleser.tasmota or stromleser.one – both solutions enable a reliable connection to the app and offer you precise real-time data.
Stromleser Tasmota is ideal for technically savvy users, while stromleser.one impresses with a particularly simple onboarding process – perfect for anyone who wants to start without prior knowledge.

Further information on installation can be found in the article on setting up stromleser.tasmota and stromleser.one .

Monitor and analyze electricity consumption live

With the Stromleser app , you get a precise overview of your current electricity consumption in real time – directly on your smartphone. Depending on the device used , historical consumption data is also displayed.

This allows you, for example, to identify when your electricity consumption is particularly high – such as at night or at certain times of day – and to derive targeted measures from this.

For example: If devices such as televisions, routers or printers constantly draw power even in standby mode, you can counteract this – for example by using smart plugs or consciously switching them off.

In addition to the live display, you can add or export manually entered values ​​on both devices – ideal for regular evaluations, such as monthly checks or sharing with third parties.

Depending on the device type, the app will show you the following values:

• Current electricity consumption
• Current performance
• Meter reading
• Possible power input
• Historical statistics (only at stromleser.one)

Compatibility with digital electricity meters

The Stromleser app works with all modern digital electricity meters that have an optical D0 interface . These include:

• Modern Metering Devices (mME): Digital meters without a communication module
• Intelligent metering systems (iMSys): Digital meters with smart meter gateway

Important: Analog electricity meters such as the classic Ferraris meter are not compatible.
You can find more information about the different electricity meters here .

Technical background: How it works

The Stromleser app accesses the consumption data from your digital electricity meter via the optical D0 interface . Standardized protocols are used to ensure secure and reliable data transmission – without interfering with existing metering infrastructure.

The technical implementation varies depending on the device:

• stromleser.tasmota It uses the open-source firmware Tasmota to transmit meter data via Wi-Fi. Configuration is done manually via the Tasmota interface, giving technically savvy users more individual customization options.
• stromleser.one uses proprietary firmware specifically designed for user-friendliness and stability. Data transfer initially occurs via Bluetooth, after which the device connects to the Wi-Fi network. Setup is fully integrated into the stromleser app and requires no technical expertise.
