MaxxiSun API

Questions & Help
1

Hello everybody,

with MaxxiSuns CCU software version v 0.41 (currently beta) it’s possible to import battery data from MaxxiCharge.
The CCU will post data via http-post to a custom url (can be inserted in the local web gui), its format is json: Maxxisun

Does anyone can provide a smart solution to get hands on this values?
As far as I know there is no Homey App for MaxxiSun?

For my personal use, it would be nice to monitor battery level, input and output (from and to battery).

Thanks for your help!

Hey everybody,

I tried a lot by myself, but as I mentioned, I am not a Programmer.
Perhaps somebody can help to get the wrong parts working.

In the MaxxiCharge Interface I added the local path to a Homey Pro 2023 Webhook: http://hp23-ip/webhook?event=maxxicharge

Then I created a new flow with a Logic Card on receiving a new webhook. It works, tested with a notification on receiving a new POST msg.
Earlier I created a new virtual device (with battery, power and so on). Now I dont know how to link the incoming JSON information to the virtual device.

I tried to trigger a HomeyScript, but something is wrong and I dont get it.

// Die ID des virtuellen Geräts
const virtualDeviceId = "ASDF";

// Mappings: Zuordnung der empfangenen Daten zu den Capabilities des virtuellen Geräts
const mappings = {
    "voltage": "measure_voltage", // Spannung in Volt
    "current": "measure_current", // Stromstärke in Ampere
    "power": "measure_power",     // Leistung in Watt
    "state_of_charge": "measure_battery" // Ladezustand in Prozent
};

// Daten aus den Argumenten des Flows abrufen
const body = args[0]; // JSON-Daten, die im Webhook übergeben wurden

// Überprüfen, ob die empfangenen Daten gültig sind
if (!body || typeof body !== "object") {
    throw new Error("Keine oder ungültige Daten übergeben.");
}

// Funktion zum Aktualisieren eines Attributs des virtuellen Geräts
async function updateVirtualDeviceCapability(capability, value) {
    try {
        await Homey.devices.setCapabilityValue({
            deviceId: virtualDeviceId,
            capabilityId: capability,
            value: value,
        });
        console.log(`Capability ${capability} erfolgreich auf ${value} aktualisiert.`);
    } catch (err) {
        console.error(`Fehler beim Aktualisieren von ${capability}:`, err);
    }
}

// Die empfangenen Daten verarbeiten
for (const [key, value] of Object.entries(body)) {
    const capability = mappings[key];
    if (capability) {
        await updateVirtualDeviceCapability(capability, value);
    } else {
        console.warn(`Keine Zuordnung für Schlüssel: ${key}`);
    }
}

console.log("Skript abgeschlossen.");

Perhaps someone can assist?

Thank you very much.
