The Problem: Wallbox Apps That Drive You Crazy

You have an EV and a wallbox, but you’re frustrated with clunky manufacturer apps and terrible smart home integration? The app is slow, confusing, and sends all your data to the cloud?

There’s a better way! With EVCC, you get a fully local solution for intelligent control of your EV charging – no cloud, no dependency, maximum control.

In the new video, I’ll show you my complete setup and how I saved over €2,500 with it!

What Is EVCC?

EVCC stands for “Electric Vehicle Charge Controller” and is an open-source software for intelligent wallbox control. What makes it special:

✅ Completely local – no cloud connection required
✅ Open source – transparent code, active community
✅ Manufacturer-independent – works with almost any wallbox
✅ Professional UI – more polished than any manufacturer app
✅ Smart Home integration – works perfectly with Home Assistant & more

With or Without a PV System

The brilliant part: EVCC works with AND without a PV system!

With PV: Intelligent surplus charging – make the most of your solar energy
Without PV: Charge on a schedule or with dynamic electricity prices

In the video, I’ll show you both scenarios!

My Setup in Detail

In my setup, I use:

PV system on the roof (optional!)
Home battery storage in the basement (optional!)
Wallbox in the garage (required)
EV (hopefully you have one 😊)
Raspberry Pi 4 running EVCC as a Docker container

My wallbox is connected to the Raspberry Pi via a Modbus cable (20 meters through the basement!). But don’t worry: depending on the wallbox model, this can also work over Wi-Fi or Ethernet.

The best part: You don’t need my complete setup! A single wallbox is enough to get started.

In the video, I’ll show you my complete installation including the wiring!

The EVCC Dashboard: A Dream!

Does this brilliant user interface look like a “hacky” open-source tool to you? I was completely blown away when I first launched it!

What You See at a Glance:

Top: Energy flows

Where is the power coming from? (PV, battery, grid)
Where is it going? (house, car, battery, grid)
Live updates every 10 seconds

Middle: Charging modes

PV: Surplus charging – solar power only
Min+PV: Minimum load + solar
Fast: Full power – regardless of source

Bottom: Details

Current charging power

Estimated charging time
Cost overview

Make sure to watch the video to see the display change in real time!

Live Demo: How Surplus Charging Works

In the video, I’ll walk you through three live scenarios:

Scenario 1: No Sun, No Car

PV system produces little (November fog)
Home battery covers household consumption
No charging possible

Scenario 2: Lots of Sun, No Car

PV system produces a decent amount
Home battery is full
Surplus is exported to the grid (wasted)

Scenario 3: Sun + Car Plugged In 🎉

PV system is producing
Household consumption is covered
Surplus flows into the car!
EVCC adjusts automatically every 10 seconds

The dynamic adjustment is impressive – check it out in the video!

Dynamic Electricity Prices: Saving Money on Autopilot

For me, this is the killer feature: EVCC supports dynamic electricity prices!

How It Works:

Create a charging plan
- When do you need the car? (departure time)
- How full should it be? (target state of charge)
EVCC automatically calculates
- When is electricity cheapest?
- How long does charging take?
- What will it likely cost?
Car charges automatically at the best time
- No manual intervention needed
- Maximum savings
- Ready on time for departure

In the video, I’ll show you the charging plan in action!

My Experience With Tibber

I’ve been using Tibber for two years – essentially the pioneer of dynamic electricity tariffs in Germany.

What Makes Tibber Special?

✅ Price changes every 15 minutes
✅ No smart meter required – works with a standard meter
✅ Perfect EVCC integration
✅ Transparent pricing

Making Use of Price Dynamics

In the video, I’ll show you the Tibber app:

You can see the price curve for the next 24 hours. The dynamics are impressive:

🟢 Cheap times: Often at night, when there’s a lot of wind/solar on the grid
🔴 Expensive times: Usually in the evening during peak grid load

EVCC automatically charges during the green phases!

The Result: €2,500 Saved!

EVCC logs all charging sessions and calculates your savings. In my case, it’s now over €2,500 euros!

If I’ve sparked your interest: Use my Tibber link in the description. We both get €50 for the Tibber Store. You support the channel and save money yourself – win-win!

Do you already have a dynamic electricity tariff? Tibber is one of the first providers to offer such a tariff in Germany. I’ve been a customer since October 2022, and it’s been a thoroughly positive experience. Tibber offers a clearly structured, modern app where you always have full oversight of your electricity tariff and costs. Pricing is very transparent: Tibber only charges what electricity actually costs on the exchange at any given moment (plus standard grid fees, etc.), plus a service fee of just €3.99 per month.

If Tibber sounds like an option for you, I’d be glad if you sign up via my referral link. That gets both you and me €100 for the Tibber Store, where you can buy various IoT hardware for your smart home. If you’re already a Tibber customer and haven’t used a referral link, you can still do so within 14 days — use code vkccaupl.

Have questions or still unsure? Don’t hesitate to reach out. I’m happy to help you figure out whether Tibber is the right choice for you. And if it turns out it isn’t — you can cancel Tibber month by month at any time!

Thank you for your support! It makes it possible for me to keep creating videos for you.

Installation: Easier Than You Think

EVCC runs as a Docker container on a Raspberry Pi 4 at my place. The installation is surprisingly straightforward:

Option 1: Docker (My Choice)

# Download and start the container
docker run -d \
  --name evcc \
  -p 7070:7070 \
  -v $(pwd)/evcc.yaml:/etc/evcc.yaml \
  evcc/evcc:latest

Advantages:

✅ Quick to set up
✅ Other services can run in parallel
✅ Easy updates

Option 2: Home Assistant Add-on

If you’re using Home Assistant OS, there’s an official add-on!

Installation:

Open the Add-on Store
Search for “EVCC”
Install & start

Even easier than Docker!

In the video, I’ll show you both options!

Configuration: YAML or Web UI

For initial configuration, you have two paths:

Classic: YAML File

This is how I did it. You edit a text file:

site:
  title: My EVCC
  meters:
    grid: ...
    pv: ...
  
chargers:
  - name: Garage Wallbox
    type: ...

For: Tinkerers who enjoy writing code Against: Slightly steeper learning curve

Modern: Web UI

Since a few versions back, there’s a graphical configuration interface!

For: Beginners who prefer simplicity Against: (None, really 😊)

In the video, I’ll show you the Web UI – super intuitive!

Wallbox Compatibility: A Huge Selection

My wallbox is connected via Modbus cable. But EVCC supports an incredibly wide range of wallboxes:

Supported Connection Types:

Modbus (my setup)
Wi-Fi
Ethernet
Cloud (if necessary)

Supported Manufacturers:

The list is impressively long:

ABL
EVSE WiFi
go-eCharger
KEBA
