SolarEdge + myStrom

What Zerofy can do with SolarEdge and myStrom

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 SolarEdge home system (3–10 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 SolarEdge 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 SolarEdge 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 SolarEdge and myStrom offer on their own

SolarEdge: The Home Load Controller also switches other loads such as pool pumps or air conditioners (2 × 8 A NO and 1 × 4 A NC contacts, larger loads via an external contactor) and can turn them off as non-essential loads during a power outage.

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 SolarEdge 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 SolarEdge and myStrom in Zerofy

1. Connect SolarEdge

Zerofy connects to SolarEdge’s monitoring cloud with the same login you use for the SolarEdge Monitoring website or the mySolarEdge app.

1. Make sure your SolarEdge inverter is online and your account has the Owner role on the site.
2. Add a new SolarEdge device in Zerofy.
3. Log in with your SolarEdge Monitoring / mySolarEdge credentials and follow the on-screen prompts.

Good to know: Your account needs the Owner role, which the installer usually assigns to the system owner during setup; ask your installer if you don’t have it. Battery and meter data depend on how your system is configured.

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.

1. Set up new myStrom plugs in the myStrom app.
2. 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 SolarEdge solar production.

About SolarEdge and myStrom

SolarEdge – Israeli company (Herzliya) known for inverters with a power optimizer on every module. Homes typically have a SolarEdge Home Wave single-phase or Home Hub three-phase inverter with optimizers, often with a SolarEdge Home Battery and SolarEdge Home smart-energy accessories. Monitoring app: SolarEdge Monitoring / mySolarEdge app.

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).
