Make your dynamic tariff smarter, and your customers stickier
Zerofy shifts EV charging, heat pumps and batteries to the cheapest hours automatically, so your customers actually benefit from your tariff, in an app with your brand.
Why dynamic tariffs fall short
Savings need flexible demand
Since 2025, German suppliers must offer dynamic tariffs. They only pay off for customers who shift their consumption, and few do that by hand.
Customers switch
Electricity is a commodity. Without a product your customers use every day, they leave at the next price change.
No line to the devices
§14a requires controllable devices to follow grid operators' dimming signals, and you have no direct connection to the chargers, heat pumps and batteries in your customers' homes.
Turn your tariff into a product customers use every day
Optimised against spot prices
Autopilot schedules devices against hourly EPEX Spot and Nord Pool prices, including grid fees, provider fees and VAT.
Your tariff in the app
Offer your own electricity tariff inside the app as an add-on, so the price and the savings are shown in one place.
Smart energy tariffsCustom signals and triggers
Define and import your own triggers and signals to control devices in your customers' homes.
§14a with no extra hardware
Embedded software on the smart meter gateway or control box passes the §14a dimming signal to Zerofy. No additional HEMS hardware needed.
VPP and flexibility (coming soon)
Pool your customers' batteries, EVs and heat pumps for flexibility and Virtual Power Plant programmes.

Frequently asked questions
Can we connect our own tariff?
Yes. Your own electricity tariff can be offered in the app as a Whitelabel add-on, and Autopilot optimises against it. More on smart energy tariffs.
How does §14a work without extra hardware?
Zerofy needs no HEMS box of its own. Embedded software on the smart meter gateway or control box passes the grid operator's dimming signal to Zerofy, which then limits the connected devices.
Can we run a VPP?
VPP and flexibility programmes are on our roadmap and marked as coming soon. Talk to us about what you are planning.
Where is the data hosted?
In the EU, on Google Cloud in Belgium. Single-tenant hosting is available as an add-on.
How long does integration take?
A Whitelabel app typically goes live within 30 days: a short definition session, about a week of setup, then launch.
