Huawei + myStrom

What Zerofy can do with Huawei 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 Huawei home system (2–10 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 Huawei 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 Huawei 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 Huawei and myStrom offer on their own

Huawei: Up to 20 Shelly devices can be connected to the SmartAssistant and switched on surplus from FusionSolar.

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 Huawei 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 Huawei and myStrom in Zerofy

1. Connect Huawei

Zerofy connects to Huawei FusionSolar with the login of a FusionSolar owner account; the older Northbound API account still works as a legacy option.

1. Check that your FusionSolar account has a verified email address (System → Personal Settings).
2. Make sure it is an Owner account; if you only have an installer or company account, invite a new user with the role Owner in the FusionSolar app.
3. Add Huawei FusionSolar in Zerofy, choose the FusionSolar login and enter the owner account’s credentials.

Good to know: Installer and company accounts don’t work, and the owner invitation can only be sent from the FusionSolar smartphone app, not the web portal. If you use the legacy Northbound API, create a dedicated account for Zerofy, because sharing it with other services can cause data gaps.

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 Huawei solar production.
