heat reader.

No, you don't need an electrician. Our reading heads operate on a plug-and-play principle: you simply attach the reading head to your meter, connect it to the power supply, and pair it with your smartphone via Bluetooth using the energieleser app.

wärmeleser reads your data exactly at the interval at which your meter sends it. Important to know: Many heat meters only transmit their values at limited intervals – often only 4 times a day. Your app will therefore not show you new values constantly, but will update itself at this rhythm.

In the event of a Wi-Fi outage, your gas meter will simply continue to read as normal – as soon as the connection is restored, your data will automatically update in the app.

In the event of a power outage, readings are interrupted because the meter head requires a constant power supply. However, unlike digital electricity meters, your gas meter cannot transmit its reading digitally on its own – so you will need to manually update the current meter reading in the app once after a power outage.

No – to retrieve your data, you only need the free energieleser app from the Apple App Store or Google Play Store. There are no hidden or ongoing costs.

Yes - our devices are Home Assistant (Silver) certified and can be integrated effortlessly. And if you prefer to process your data yourself: A CSV export is possible directly from the app at any time.

Once your smart meter reader is attached and set up, it measures directly what it receives from your meter. Since your gas reader reads via impulses, you will see your first data as soon as gas is actually consumed. Only the transfer to your app might take a moment.
