Growatt + myStrom
Switch appliances on Growatt solar surplus with myStrom: Zerofy turns them on when there's surplus and supports dynamic tariffs. No extra hardware.

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 Growatt and myStrom via cloud APIs in minutes.
Growatt + myStrom: TL;DR
Yes, Growatt and myStrom work together in Zerofy. Zerofy reads your Growatt system through ShinePhone and controls your myStrom switch through the myStrom cloud. Smart mode also follows dynamic electricity prices and solar forecasts. No extra hardware needed.
What Zerofy can do with Growatt and myStrom
| Solar data from Growatt | Live values and history, new data every 5 min, including the battery |
| Connection to myStrom | Cloud – your myStrom account |
| Switch on and off | Yes |
| Power history | Yes |
| Use as balcony solar meter | Yes |
| Autopilot: Solar mode | Yes |
| Autopilot: Smart mode (tariffs and forecasts) | Yes |
In practice
- Solar mode switches your myStrom switch on when there’s surplus, following your priority order and minimum runtime. Smart mode instead runs for a set number of minutes within the hours you allow.
- A myStrom plug can also measure a balcony solar system: set it as balcony solar meter in Zerofy.
- With a typical Growatt home system (2.5–10 kW), plug loads get surplus on most sunny days; use priorities to decide whether they or bigger devices such as an EV charger come first.
- Zerofy gets new Growatt data every 5 minutes and adjusts accordingly. A minimum runtime and an activation threshold in Autopilot keep passing clouds from interrupting switching.
- Zerofy also shows your Growatt battery, so you can see whether surplus goes into the battery or into your appliances.
- If you have a plug-in balcony PV system, plug it into a WiFi Switch and set that switch as balcony solar meter in Zerofy, so its production is counted in your energy flows.
What Growatt and myStrom offer on their own
Growatt: The GroPlug-X smart plug works with the NOAH 2000 and NEXA 2000 balcony batteries: it measures the load plugged into it so the battery can adjust its discharge.
myStrom: The myStrom app records mini-PV production measured by a WiFi Switch every 30 seconds, and “Solar Actions” and “Power Actions” can switch other myStrom devices on these values, e.g. allow e-bike charging from 200 W; this needs the myStrom PLUS subscription (EUR 3.49/year). Whole-house surplus control comes from energy management partners such as Solar Manager or clever-PV, not from an inverter maker.
Zerofy connects the two: it reads Growatt production and controls your myStrom switch to match, together with your other devices in one app, with dynamic tariffs and forecast-based Smart mode.
Setting up Growatt and myStrom in Zerofy
1. Connect Growatt
Zerofy connects to the Growatt cloud: you log in with your ShinePhone credentials.
- Make sure your inverter is online and registered in the ShinePhone app.
- In Zerofy, choose Growatt and log in with your ShinePhone username and password.
Good to know: Inverter data is supported; battery and meter data may only be partly available depending on the system. Battery control and using the battery in Autopilot are listed as coming soon for Growatt.

2. Connect myStrom
Zerofy connects to your myStrom account; it switches the plugs on and off, records their power every 5 minutes and lets Autopilot run them on solar surplus or in Smart mode.
- Set up new myStrom plugs in the myStrom app.
- In Zerofy, add myStrom and link your myStrom account.

3. Turn on Autopilot
In Zerofy, open your myStrom switch, turn on Autopilot and choose Solar – or Smart to also use dynamic tariffs and forecasts. Set the priority, activation threshold and minimum runtime.
Dynamic tariffs
Zerofy can also run your myStrom switch on dynamic electricity prices (EPEX Spot or Nord Pool, e.g. Tibber or aWATTar) or on a fixed time-of-use tariff. Smart mode combines those prices with forecasts of your household consumption and your Growatt solar production.
About Growatt and myStrom
Growatt – Growatt (Shenzhen Growatt New Energy, China, founded 2011) makes string and hybrid inverters such as the MIN TL-X and MIN TL-XH series, the NEO microinverters and the NOAH 2000 balcony battery. Its own ecosystem, GroHome, adds the THOR wallboxes, APX HV batteries and the GroBoost heater controller. Monitoring app: ShinePhone.
myStrom – myStrom AG is a Swiss company based in Zurich, founded in 2011. Its WiFi Switch is a smart plug for up to 16 A that switches appliances and measures their power, and it is also used to measure the output of plug-in balcony PV systems. Products: myStrom WiFi Switch (CH and Schuko versions), WiFi Switch Zero, WiFi Switch Ex (outdoor, Wieland connector for mini-PV).
