ABB (Power One) Aurora Web Inverter Monitor (WIM): WIFI configuration and REST Server – 6

by · Published · Updated

Spread the love
           

For my inverter control unit I was thinking of a web interface, so first you need an easy way to connect the device to the WiFi network.

ABB PowerOne Aurora Web Inverter Centraline WIFI configuration and REST Server

For this purpose exist a simple library that I explain in “How to manage dynamic WIFI configuration on esp8266 or esp32“, this allows you to start the control unit starts in AP mode and from here you can connect and configure your wifi.

ABB Aurora netwarok configuration: select AP
ABB Aurora netwarok configuration: select AP

When you connect to the AP, automatically you are redirected to the WIFI configuration page, here you con select your AP and insert your password.

ABB Aurora netwarok configuration: configure WiFi
ABB Aurora netwarok configuration: configure WiFi
ABB Aurora netwarok configuration: select SSID e password
ABB Aurora netwarok configuration: select SSID e password

Now you can connect to the url http://InverterCentraline but in some network configuration not work mDNS (Multicast DNS) so you must check what IP you have received, you can connect to the Serial port for debug or use program (for Android phone or Desktop) like Fing that scan all device in your network.

If no configuration is specified, the command that starts the whole process is

    wifiManager.autoConnect("InverterCentralineConfiguration");

otherwise if a configuration is found, the data will be set using this code

				DEBUG_PRINT(F("Set static data..."));
				if (isDNS){
					wifiManager.setSTAStaticIPConfig(_ip, _gw, _sn, _dns1, _dns2);
				}else{
					wifiManager.setSTAStaticIPConfig(_ip, _gw, _sn);
				}

But be careful, WiFiManager by default does not support DNS configuration, so you will have to use my library

https://github.com/xreef/WiFiManager

I added DNS management and it allows us to use esp8266 as a client and make requests to the outside.

When the device restarts, hopefully :D, you can always use that ip to manage the inverter.

When you restart the device, If all It’s ok :D, you can use that ip to manage the Inverter.

REST Server

I separate REST server from Web Server, and I implemented a series of API to control the device in all part.

ABB Aurora REST Server Schema

You can have more information about REST server on esp8266 on these articles “How to create a REST server on esp8266 or esp32“

This is the code where I census the rest REST end-points.

void restServerRouting() {
//	httpRestServer.header("Access-Control-Allow-Headers: Authorization, Content-Type");
//
    httpRestServer.on("/", HTTP_GET, []() {
    	httpRestServer.send(200, F("text/html"),
            F("Welcome to the Inverter Centraline REST Web Server"));
    });
    httpRestServer.on(F("/production"), HTTP_GET, getProduction);
    httpRestServer.on(F("/productionTotal"), HTTP_GET, getProductionTotal);
    httpRestServer.on(F("/monthly"), HTTP_GET, getMontlyValue);

    httpRestServer.on(F("/historical"), HTTP_GET, getHistoricalValue);

    httpRestServer.on(F("/config"), HTTP_OPTIONS, sendCrossOriginHeader);
    httpRestServer.on(F("/config"), HTTP_POST, postConfigFile);
    httpRestServer.on(F("/config"), HTTP_GET, getConfigFile);

    httpRestServer.on(F("/inverterInfo"), HTTP_GET, getInverterInfo);
    httpRestServer.on(F("/inverterState"), HTTP_GET, getInverterLastState);
    httpRestServer.on(F("/inverterDayWithProblem"), HTTP_GET, inverterDayWithProblem);
    httpRestServer.on(F("/inverterDayState"), HTTP_GET, getInverterDayState);

    httpRestServer.on(F("/serverState"), HTTP_GET, getServerState);

    httpRestServer.on(F("/battery"), HTTP_GET, getBatteryInfo);

    httpRestServer.on(F("/reset"), HTTP_GET, getReset);
}

All endpoints can operate in CORS (check REST server article).

You can find all end point with example, documentation and how to call these in various language at this link.

Here the documentation of the API.
