Huawei + PHNIX

What Zerofy can do with Huawei and PHNIX

In practice

• Autopilot isn’t available for PHNIX yet, so Zerofy won’t run your PHNIX heat pump on solar surplus automatically. You can see Huawei production and PHNIX in one app and adjust the room temperature and flow temperature from there.
• Because Zerofy does not run PHNIX units on surplus automatically, put the heating or pool-heating window into the middle of the day with a schedule; pool heat pumps run mainly in summer, when midday PV output is highest.

What Huawei and PHNIX offer on their own

Huawei: The SmartAssistant (EMMA) switches one SG Ready heat pump directly through its DO dry contacts or an external relay, and a second one through a Shelly. It also controls Vaillant aroTHERM plus via EEBUS and the Askoheat+ heating rod via Modbus TCP.

PHNIX: PHNIX’s “PV Ready” function lets the heat pump adjust its compressor frequency to the available solar power, controlled by a home energy manager or, if there is none, by PHNIX’s own Smart Meter. A “Spot Time” mode works with grid prices (target temperature, maximum frequency, six daily timers), and the Heco series also has an SG Ready interface.

Zerofy connects the two: it reads Huawei production and controls your PHNIX heat pump to match, together with your other devices in one app.

Setting up Huawei and PHNIX 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 PHNIX

Zerofy connects to the PHNIX cloud with your PHNIX app login and shows the heat pump’s live status; you can set the room temperature and the water circulation temperature from Zerofy.

1. Connect the heat pump to the internet and register it in the PHNIX app.
2. In Zerofy, add PHNIX and log in with your PHNIX account credentials.

Good to know: Zerofy’s Autopilot does not yet run PHNIX heat pumps on solar surplus or dynamic prices; control from Zerofy is manual or by schedule.
