Sungrow + tado°

What Zerofy can do with Sungrow 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 Sungrow 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 Sungrow and tado° offer on their own

Sungrow: SH-RT inverters have a DO relay that the iSolarCloud app can switch on export (Intelligent Mode: on once export reaches a set power, for at least 20 minutes), for example for an SG Ready heat pump via a contactor. The iHomeManager also has a DO port for heat pump control.

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 Sungrow production and controls your tado° thermostats to match, together with your other devices in one app.

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.
