SL Energy + tado°

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

SL Energy: SL Energy sells its own heat pumps (SL-HP9KL and SL-HP12/18KR, 12.6 to 23.8 kW, R32) in the iShare-Home package, and its SmartBox gathers data from inverter, meter, wallbox and heat pump. Whether the heat pump runs on solar surplus isn’t documented publicly.

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

Setting up SL Energy and tado° in Zerofy

1. Connect SL Energy

Zerofy connects to the SL Energy cloud: you log in with your SL Energy monitoring account (the one you use in the Smart M app).

1. Make sure your inverter is online and registered on the SL Energy monitoring platform.
2. In Zerofy, choose SL Energy and log in with your SL Energy account to grant access.

Good to know: For the battery, Zerofy supports forced charging but not switching the battery mode.

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.
