Automatically control your devices when solar production exceeds consumption.
Dynamic Tariffs
Optimize for electricity prices. Charge or run devices when rates are lowest, and use solar when prices are high.
Cloud Integration
No hardware required. Connect your Hoymiles and Mystrom via cloud APIs in minutes.
Hoymiles + Mystrom: TL;DR
Connect your Hoymiles solar system with your Mystrom smart plug using Zerofy. Automatically control devices with solar surplus or optimize for dynamic electricity tariffs. No additional hardware required – setup in minutes via cloud.
Solar Automation with Hoymiles and Mystrom
Combine the power of your Hoymiles PV system with your Mystrom smart plug for intelligent solar automation. Zerofy monitors your real-time solar production and automatically adjusts control to match your available surplus.
What is Solar surplus control?
Solar surplus control means your smart plug operates primarily with the electricity your solar panels produce. Instead of feeding excess power to the grid at low rates, you use it yourself – saving money and maximizing self-consumption.
With Hoymiles + Mystrom via Zerofy:
- Automatic adjustment – Control follows solar production in real-time
- Smart scheduling – Combine solar usage with time-based rules
- Smart Mode – Uses forecasts of household consumption and solar production
How It Works
Connect Hoymiles
Link your Hoymiles cloud account to Zerofy
Connect Mystrom
Add your Mystrom smart plug via cloud login
Enable Autopilot
Turn on solar surplus control mode
Use Smart
Your smart plug operates automatically with solar power
Dynamic Tariff Integration
Beyond solar surplus control, Zerofy can optimize your Mystrom for dynamic electricity tariffs based on EPEX Spot or Nordpool prices (e.g., Tibber, aWATTar, Energinet) or any manually defined tariff schedule.
Unlike simple “cheapest hours” approaches, Zerofy’s Smart Mode goes further: it uses forecasts of your household consumption and solar production to find the overall optimum.
Why No Hardware Required?
Traditional solar controllers require a dedicated hardware box. Zerofy takes a different approach:
- Cloud-to-cloud integration – Connects directly to Hoymiles and Mystrom cloud APIs
- No electrician needed – Setup takes minutes, not hours
- No upfront cost – Just download the app and connect
- Always up-to-date – New features added automatically
