## Code setup

1. Create a file named `credentials.h` inside the **include/** folder.

2. Expose your wifi credentials in the following manner:

```c

#if !defined(CREDS_H)

#define CREDS_H

char *ssid = "YOUR_WIFI_SSID";

char *password = "YOUR_WIFI_PASSWORD";

#endif // CREDS_H

```

3. Adjust the API-Endpoint inside `main.cpp` to the address where your SunShareAPI is running (e.g replace `rpi2-node-1` with an ip address of your choice):

```c

InverterDataProvider data_provider("http://rpi2-node-1/inverter-data");

```

## Display modes

With the KEY1 button, mentioned above, it's possible to switch through different display modes. The default display mode (MODE1) shows the current battery level, yield and the power consumption.

- MODE1: Battery level / yield / power consumption

- MODE2: Large battery icon

- MODE3: Age of the dataset that is displayed (timestamp)
