Hoymiles + Alpha Innotec

What Zerofy can do with Hoymiles and Alpha Innotec

In practice

• Hot water is the simplest heat store: Autopilot can use the hot-water boost of your Alpha Innotec heat pump to heat water in hours with surplus.
• A heat pump draws roughly 1–3 kW while running. A Hoymiles balcony system covers only a small part of that, a rooftop system (Hoymiles systems range up to 10 kW) much more on sunny days.
• Zerofy gets new Hoymiles data only every 15 minutes, so the heat pump reacts to clouds with some delay. A slightly higher activation threshold and a minimum runtime in Autopilot keep it steady.
• If the PV-Ready contact is wired to your inverter as well, decide which system triggers the hot-water run so the tank isn’t heated twice; with Zerofy the boost follows your inverter’s live surplus from its cloud, without extra wiring.

What Hoymiles and Alpha Innotec offer on their own

Hoymiles: On the three-phase HiOne all-in-one storage system (G3), Hoymiles has a dry contact (DO1) for SG Ready heat pumps, but the manual (January 2026) lists heat pump control as “coming soon”. Hoymiles microinverters have no heating control.

Alpha Innotec: All alpha innotec heat pumps with Luxtronik 2.0 or newer are PV-Ready and SG-Ready: a potential-free contact from the inverter (or a relay) starts the heat pump, which then heats at full power up to the return-temperature limit and makes hot water up to the maximum flow temperature. alpha innotec doesn’t name specific inverters; any inverter or energy manager with a switching contact works.

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

Setting up Hoymiles and Alpha Innotec 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 Alpha Innotec

Zerofy reaches alpha innotec heat pumps through the myUplink cloud, the same connector used for NIBE, with your myUplink login; Autopilot controls the hot-water boost.

1. Register the heat pump (Luxtronik 2.1, current software) in the myUplink app.
2. Make sure your myUplink account has the subscription needed for remote control.
3. In Zerofy, connect myUplink and log in with your myUplink credentials.
4. Enable Autopilot (Solar or Smart mode) for the hot-water tank.

Good to know: Only heat pumps on myUplink (Luxtronik 2.1) can be reached; Luxtronik 2.0 units that use heatpump24 can’t. Zerofy steers only the hot-water boost, not room or flow temperature.

3. Turn on Autopilot

In Zerofy, open your Alpha Innotec heat pump, 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 Alpha Innotec heat pump 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.

About Hoymiles and Alpha Innotec

Hoymiles – Hoymiles (Hangzhou, China) is one of the largest microinverter makers. In Europe it is best known for balcony systems such as the HMS-800W-2T (switchable 600/800 W) with the MS-A2 balcony battery, and it also sells HYS/HYT hybrid inverters with home batteries. Monitoring app: S-Miles Cloud (S-Miles app).

Alpha Innotec – alpha innotec is a German heat pump brand of ait-deutschland in Kasendorf, Bavaria. Its heat pumps run on the Luxtronik controller; units with Luxtronik 2.1 connect to the myUplink cloud, older Luxtronik 2.0 units use heatpump24. Products: Air-to-water and brine-to-water heat pumps with Luxtronik 2.1 control (myUplink) or Luxtronik 2.0 (heatpump24).
