What is a wallbox and why do you need one?

A wallbox is a charging station for your EV that you can mount at home, for example in your garage, under your carport or at your parking space. It connects the car to your home's electricity supply and can deliver up to 22 kW, compared with just 2.3 kW from a household socket. For home use, the German motoring club ADAC recommends an 11 kW wallbox. That's usually enough to charge even larger batteries overnight.

Reasons to charge at home with a wallbox:

  • You charge while the car is parked anyway – in the evening, overnight or at the weekend, and you no longer have to hunt for a free public charger.
  • You pay your household electricity rate. It's usually cheaper than charging at public charging points.
  • You charge safely. A wallbox is built for hours of charging and has protection against fault currents on board. The go-e Charger Gemini flex, for example, has a DC protection module that detects both DC and AC faults.

go-e is a wallbox maker based in Feldkirchen in Carinthia, Austria, and was founded in 2015. By its own account, go-e launched the first wallbox that could also be used on the move in 2017. All go-e wallboxes are connected to the internet and can be controlled via an app. That connection is how tado° Smart Charging tells the wallbox when to charge.

How do go-e wallboxes work with tado° Smart Charging?

Smart Charging is a feature in the tado° app. It connects your dynamic electricity tariff to your EV or wallbox and schedules every charging session so it falls in the cheapest hours.

With an hourly dynamic tariff, you pay a different price every hour, depending on the power exchange. When it's windy or sunny, the price drops. If you charge at night or around midday instead of in the early evening, you often pay a lot less per kilowatt hour.

tado° tip

You can get the right tariff directly from us: HOURLY from tado° Energy in Germany and aWATTar HOURLY in Austria. Both tariffs work with tado° Smart Charging and your go-e wallbox, and Smart Charging is included for the entire term of your tariff.

What do you need for tado° Smart Charging?

  • A compatible wallbox (such as go-e) or a compatible EV
  • An hourly dynamic electricity tariff, such as tado° HOURLY in Germany or aWATTar HOURLY in Austria
  • A smart meter, which your supplier needs for hourly billing
  • The tado° app with Smart Charging: free with our electricity tariffs (otherwise €2.99 a month)

How to set up Smart Charging with your go-e wallbox

  • Mount the wallbox. You fit the Gemini flex yourself with the wall bracket included. The CORE and PRO CABLE are installed by a qualified electrician.
  • Activate Smart Charging. In the tado° app, activate Smart Charging and connect your electricity tariff and your go-e wallbox.
  • Set your target. Enter the charge level your car should reach and by when. You can move your "departure time" earlier or later at any time.
  • Optional: connect your solar system. If you have a photovoltaic (PV) system, Smart Charging uses your solar power first. The app plans charging around your system's expected output. You can choose to charge purely for solar, purely for price or with a mix of both. That way, as much power as possible goes from your roof into your car, and the rest comes from the grid during cheap hours.
  • Charge. As soon as the car is plugged in, Smart Charging spreads the charge across the cheapest (and greenest) hours before your planned departure. With 7-day price optimisation, the app can also plan across several days.
  • Check. The app shows you when charging happens. Looking back, you can also see how much electricity went into your car and at which exchange prices.

Which go-e wallbox is right for you?

The three models available from tado° differ mainly in how they're connected. All of them charge at up to 11 kW, and you can protect them from unauthorised use with an RFID chip or via the app.

Feature go-e Charger Gemini flex go-e Charger CORE go-e Charger PRO CABLE
Type Portable wallbox in a wall bracket Permanently installed Permanently installed
Connection Plug for a red CEE socket (16 A) Qualified electrician Qualified electrician
Charging cable Own Type 2 cable needed 6 m, permanently attached 6 m, permanently attached
Electricity meter Basic meter Basic meter (not calibrated) MID-compliant meter
Best for Renters, parking spaces with a CEE socket, travel Homeowners with their own parking space Company cars, blocks of flats

An MID meter is an electricity meter certified under the EU Measuring Instruments Directive. You need one if you have to account for the electricity you charge with verifiable records, for example with your employer.

How much can you save with Smart Charging?

tado° Smart Charging users save €300¹ a year on average. This figure is based on a comparison of charging costs on an average standard electricity contract with a dynamic tariff plus Smart Charging. How much you actually save depends on your tariff, how you drive and how wholesale electricity prices develop.

An example shows the scale. Say you commute to the office on Tuesdays and Thursdays. On Sunday evening, you plug in your car and set it to reach 80% by 7 am on Tuesday. The app then waits for the cheapest hours, such as a windy night, instead of charging straight away during the expensive evening hours.

Factor Example value
Distance driven per year 12,000 km
Consumption 18 kWh/100 km
Charged at home 2,160 kWh
Assumed price difference between cheap hours and evening hours 10 cents/kWh
Savings per year approx. €216

Note: the 10 cents/kWh is an assumption for this example, not a guaranteed figure. On some days the gap between expensive and cheap hours is smaller; on windy or sunny days it's bigger.

tado° tip

Plug your car in as soon as you get home, even if you won't need it for another two days. The longer the car stays plugged in and the later your departure time, the more hours Smart Charging can choose from. Still, leave yourself a small buffer: it's better to set your departure time half an hour early than to cut it too fine.

Portable wallbox in a rented flat: what do you need to know?

A permanently installed wallbox needs the property owner's consent. The go-e Charger Gemini flex, on the other hand, simply plugs in. At home, you can hang it in the wall bracket included, which you can screw to the wall yourself in a few minutes. You can also use it without the bracket: at 1.63 kg, it fits in the boot and charges on the go from any suitable CEE socket. When you move house, it comes with you.

‍

You'll still need to do some groundwork. Here are three things you should know:

You need a red CEE socket. The Gemini flex has a plug for a red 16 A CEE socket, often called a three-phase socket. If there isn't one at your parking space yet, a qualified electrician installs it. A residual current device (RCD) of at least type A must be installed upstream of the socket. With an adapter, the Gemini flex can also charge from a household socket, but at no more than 2.3 kW.

Even a portable wallbox must be registered. You must notify your grid operator of every EV charging device before you start using it. For the 11 kW Gemini flex, this notification is enough. Since 2024, every grid operator must also offer this notification on its website. You only need your grid operator's consent for more than 12 kVA per installation, which is roughly 11 kW. In practice, that applies to 22 kW wallboxes or to several charging points on one home connection.

As a renter, you're entitled to a charging point. Under German law, tenants and flat owners generally have a right to a charging point. You should still agree the new CEE socket at your parking space with your landlord or property management, because it's a permanent installation.

The rules above apply in Germany. In Austria, it's best to ask your grid operator directly what notification it needs for a charging device.

FAQs

Do I need an electrician for a portable wallbox?

Not to start using the go-e Charger Gemini flex. You fit the bracket yourself and plug the wallbox into a red 16 A CEE socket. If there's no such socket at your parking space, a qualified electrician needs to install one. A residual current device (RCD) of at least type A must be installed upstream.

Do I have to register a portable wallbox with my grid operator?

Yes. In Germany, you must notify your grid operator of every new charging device before you start using it, and that includes a portable wallbox. You only need approval for charging power above 11 kW, so for the 11 kW Gemini flex, registering is enough.

Do I need a dynamic electricity tariff to use tado° Smart Charging?

No, not necessarily. tado° Smart Charging saves you the most when you combine it with an hourly dynamic electricity tariff (such as HOURLY from tado° Energy in Germany or aWATTar HOURLY in Austria). If you have your own photovoltaic system, however, you can also use Smart Charging without a dynamic tariff to charge your EV with your own solar power first.

How much does tado° Smart Charging cost?

With an electricity tariff from tado° Energy or aWATTar, Smart Charging is free for the entire term of your tariff. With a dynamic tariff from another provider, the feature is currently free for 6 months and then costs €2.99 a month, cancellable monthly.
