WattWächter

Know what your electricity costs — not just what it uses. WattWächter 2.0 turns your meter readings into live values, kWh and euros.

The WattWächter app is used to set up and operate the WattWächter Plus device for reading digital electricity meters.

With the app, WattWächter Plus devices can be configured, connected to the local Wi-Fi network, and used to follow your electricity use — live, over time, and in euros. Communication takes place locally via Bluetooth and the home network.

Note: This app works exclusively in combination with a WattWächter Plus hardware device.

Features at a glance:

• Setup of the WattWächter device via Bluetooth
• Connection of the device to the local Wi-Fi network
• Live view of current power draw and feed-in
• Consumption in kWh for today, the current month and the current year
• Costs based on your own tariff: energy price, base fee and feed-in compensation
• History for day, week, month and year — swipe between periods, open any chart full screen
• Clear and structured presentation of measurement values
• Several meters in one app, switch between them at any time
• Status and diagnostic information
• Export of diagnostic data to support customer service
• Guided tour with a demo meter, so the app can be explored before the device arrives
• Available in German, English, Spanish, French, Italian and Dutch, in light and dark mode

The app processes measurement and device data locally. Optionally, data can be synced to the cloud for remote access; an account is only required for that.
