Huawei + tado°

What Zerofy can do with Huawei and tado°

In practice

• Autopilot isn’t available for tado° yet, so Zerofy won’t run your tado° thermostats on solar surplus automatically. You can see Huawei production and tado° in one app and adjust the room temperature from there.
• A temperature you set from Zerofy works like a manual change in the tado° app: it overrides the tado° schedule for that zone with no end time, so the zone only goes back to its schedule when you resume it in the tado° app.

What Huawei and tado° 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.

tado°: With the Heat Pump Optimizer X and the paid “Balance for Heat Pumps” service, tado° shifts heat pump operation into the hours its PV forecast expects solar power. The forecast uses the PV size, address, roof direction and tilt you enter plus the local weather forecast, not live inverter data; the Smart AC Control has no solar function.

Zerofy connects the two: it reads Huawei production and controls your tado° thermostats to match, together with your other devices in one app.

Setting up Huawei and tado° 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 tado°

Zerofy logs in to your tado° account and shows temperature and humidity of your tado° zones, and you can set the room temperature from Zerofy; Autopilot does not control tado° devices.

1. Set up your tado° devices in the tado° app.
2. In Zerofy, add Tado and log in with your tado° app credentials.

Good to know: Zerofy does not run tado° on solar surplus or dynamic prices; use it in Zerofy for monitoring and manual temperature changes.
