Hoymiles + Easee

What Zerofy can do with Hoymiles and Easee

In practice

• Zerofy adjusts the charging current of your Easee charger but doesn’t switch phases. On a three-phase connection, solar charging needs at least about 4.1 kW of surplus (6 A × 3 × 230 V); on a single-phase connection about 1.4 kW.
• Hoymiles systems range from balcony kits to rooftop systems (0.8–10 kW). A balcony system never reaches the 1.4 kW needed to start charging; a rooftop system of a few kW does on bright days, and three-phase charging needs about 4.1 kW.
• Zerofy gets new Hoymiles data only every 15 minutes, so charging reacts to clouds with some delay. A slightly higher activation threshold and a minimum runtime in Autopilot keep it steady.
• If your car is connected to Zerofy too, turn on Autopilot for either the car or the charger, not both.
• Easee needs at least 6 A to start, which is about 1.4 kW on one phase and 4.1 kW on three. If the charger’s phase mode is set to automatic, Zerofy warns you and plans with the three-phase minimum until Easee reports single-phase charging; a fixed single-phase setting lets charging start from about 1.4 kW, but caps it at about 3.7 kW.

What Hoymiles and Easee offer on their own

Hoymiles: Hoymiles sells its own AC chargers (VAS-7-G2 single-phase 7 kW, VAT-11-G2 and VAT-22-G2 three-phase) with a green power mode that follows PV surplus, but only together with a Hoymiles storage inverter (HYS, HAS, HYT, HAT), not with microinverters. An 800 W balcony system on its own never reaches the about 1.4 kW a charger needs at its 6 A minimum.

Easee: Easee’s own solar charging needs an Easee Equalizer on the site (the P1/HAN version reads the smart meter, Equalizer Amp measures with current sensors) and Easee as site operator. The Easee app then offers “Surplus only” and “Limited grid usage”; it does not read any inverter directly.

Zerofy connects the two: it reads Hoymiles production and controls your Easee charger to match, together with your other devices in one app, with dynamic tariffs and forecast-based Smart mode.

Setting up Hoymiles and Easee in Zerofy

1. Connect Hoymiles

Zerofy connects to the Hoymiles S-Miles Cloud with your S-Miles account and reads your PV production.

1. If your installer hasn’t set up your plant yet, register it in the S-Miles Installer app (use DIY mode if you install it yourself).
2. In Zerofy, add an inverter, choose Hoymiles and log in with your S-Miles credentials.
3. Use Autopilot (Solar Mode) to switch devices on solar surplus.

Good to know: Zerofy reads PV production only from Hoymiles, not grid meter or battery data, and stores the power history in 15-minute steps (5 minutes for most other brands).

2. Connect Easee

Zerofy logs in to your Easee account and starts, stops and sets the charging current through the Easee cloud.

1. Make sure your Easee charger is online and added to your Easee account.
2. In Zerofy, add an Easee charger and log in with your Easee account.

Good to know: Data synchronisation depends on how often the Easee cloud updates, so live values in Zerofy can lag behind the charger.

3. Turn on Autopilot

In Zerofy, open your Easee charger, 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 Easee charger 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 Hoymiles solar production.
