NOTE This app requires that Homey and the V2C Wallbox are connected to the same local network. The app communicates with the charger using HTTP commands based on V2C’s official specifications. For proper functionality, it is also necessary to assign a static IP address to the Wallbox on your Wi-Fi router.
IMPORTANT: For real house consumption data, solar production, and dynamic power management features, your V2C Wallbox must be properly connected to your electrical installation using measuring clamps or directly to your solar inverter, and dynamic mode must be enabled. Without these connections, these advanced features will not provide accurate data.
Ensure both Homey and the V2C Wallbox are on the same local network.
Add your V2C Wallbox device through the app.
Control and monitor your charger using Homey’s intuitive interface.

Script is outdated - i have added this translation W to Amp to a flow card
You might find a Homey Script useful that converts watts to amps. With this and the SET intensity card, you can subsequently control the charging based on the surplus energy from your PV system. This script calculates the three-phase power at 230V voltage referenced to neutral.
// Function to convert Watts to Amps in a three-phase system with a phase voltage of 230V
function convertWattsToAmps(powerWatts) {
const voltage = 230; // Phase voltage (V)
const powerFactor = 1; // Power factor (cos φ), assumed to be 1
// If the input value is negative, return 0
if (powerWatts < 0) {
return 0;
}
// Calculation of current in Amps in a three-phase system (for total power distributed across three phases)
const currentAmps = powerWatts / (3 * voltage * powerFactor);
return currentAmps;
}
// Capture the value from arguments (args) and round it to the nearest whole number
const power = Math.round(args[0]); // Assume the power value in watts will be the first argument
// Constant power value for potential supplementation from the grid (in Watts)
const additionalPower = 1000;
// Use the value for calculation
let current = convertWattsToAmps(power);
// Check if the current is less than 6 A
if (current < 6) {
// Add the constant value to the power and recalculate the current
current = convertWattsToAmps(power + additionalPower);
}
// Round the result down to the nearest whole number
current = Math.round(current);
// Save the rounded result into a variable using the new API
tag("currentInAmpsPrimary", current);
// Output to console (for debugging)
console.log(`The current is ${current} A`);
This script will help you manage the charging based on the energy surplus from your PV system by converting power in watts to current in amps for a three-phase system with 230V.
First, I calculate the current average overflow from my photovoltaic system (PVE) over the last 1 minute. This allows me to filter out short-term fluctuations, such as when a cloud passes over the sun.
Next, I control the flow for starting/pausing charging and possibly adjusting the current in Amps. The flow could probably be simplified :). At a minimum, by setting the current to 0 Amps in case of a pause. However, I haven’t tried that yet.
Hi, current integration is only via local HTTP API, so there has to be same wifi network? How about using some of TP-Link powerline adapters to create coverage via electrical wires?
