EHW+

EHW+ is an all-in-one app to record and evaluate electricity, heating, and water readings. It supports a wide range of meter types, including PV/solar feed-in meters, and offers unlimited meters with minute-by-minute calculations, cost overviews, and tips to reduce consumption and protect the climate. The app also lets you compare your usage to the German average and identify which rooms or devices drive the most energy.

Free basic features include import/export options (JSON and CSV), cloud sync for multiple properties, dark mode, meter replacement detection, and a twelve-month consumption view with cost calculations. It also lets you manage many residential units, vote on next features, and access tips about energy costs. The product is offered with optional In‑App purchases or a monthly subscription; privacy terms and a consent manager are available in-app.
