powerfox

powerfox is a German open energy management system for digital electricity, water, and heat meters, with over 40,000 connected households. With a compact add-on module for your electricity meter and an intelligent app, powerfox makes your energy consumption visible.

Since its founding, the company has pursued one clear mission: to create transparency in energy usage - so people can make smarter, more sustainable, and more cost-efficient decisions. With powerfox and Homey, your energy meter meter becomes the heart of a smart energy ecosystem.

Bridging the Gap Between Meter and Smart Home

The powerfox poweropti bridges the gap between traditional utility meters and the modern smart home. Poweropti is available in electricity, gas and water metering variants, compatible with a large variety of utility meters used across Europe.

The poweropti module installs directly onto your existing utility meter - without any invasive modifications. Installation takes just a few minutes, after which the device securely transmits live consumption data to the powerfox cloud. From there, the powerfox app and compatible platforms like Homey allow users to gain insights, run analyses, and automate energy-saving actions based on real-time data.

Now Supporting Dynamic Electricity Tariffs

powerfox now supports dynamic electricity pricing. That means you can track and respond to changing energy prices - directly from within powerfox and Homey.

If you’re using a dynamic provider like Tibber or Awattar, you can now automate your high-consumption devices (such as your washing machine or EV) to run only during times when electricity prices are low. This smart combo of real-time consumption and market data helps you save energy and money - effortlessly.

Imagine this: Homey detects via powerfox that the current electricity price is low. Your EV is plugged in - so charging begins automatically. As prices go back up, Homey pauses the process. You only charge during the most affordable times. The result? Maximum savings with minimal intervention.

powerfox + Homey = Smart Energy at Home

The integration of powerfox and Homey brings more transparency, control, and automation to your home energy use - without any technical hassle. Whether you’re looking to reduce consumption, lower costs, or simply be more energy-conscious: powerfox and Homey help you take the first step toward a smarter energy future.

By integrating with Homey, your energy data doesn’t just become visible - it becomes actionable. Homey receives live meter readings via the powerfox app and turns them into powerful automation triggers. This enables you to take smart control of your devices based on actual energy consumption.

Whether it’s your fridge, dishwasher, or EV charger, Homey can detect when and how much energy is being used. Automated with Homey Flows, you can respond intelligently: power down certain devices during peak times or schedule usage during periods of low demand.
