Send Total Power and Yield too MQTT

[dhaberhausen]

I have four micro converters and I need the total power and energy from all converters as a MQTT value.
Therefore changed the WebApi_ws_live.cpp file and set the values after calculation int the MqttHandleDtuClass.

177 MqttHandleDtu.setTotalPvYield(totalPower, totalYieldDay, totalYieldTotal);

In the MqttHandleDtuClass is publish the values with the other DTU values

    MqttSettings.publish("dtu/totalPower", String(totalPower));
    MqttSettings.publish("dtu/totalYieldDay", String(totalYieldDay));
    MqttSettings.publish("dtu/totalYieldTotal", String(totalYieldTotal));

What do you think? Is this a general good feature? Should I check it in? Or is there a better way to do it?

Thats already implemented.

OpenDTU/docs/MQTT_Topics.md

Lines 17 to 27 in 90a0cb6

	Enabled inverter means, that only inverters with "Poll inverter data" enabled are considered.
	| Topic | R / W | Description | Value / Unit |
	| --------------------------------------- | ----- | ---------------------------------------------------- | -------------------------- |
	| ac/power | R | Sum of AC active power of all enabled inverters | W |
	| ac/yieldtotal | R | Sum of energy converted to AC since reset watt hours of all enabled inverters | Kilo watt hours (kWh) |
	| ac/yieldday | R | Sum of energy converted to AC per day in watt hours of all enabled inverters | Watt hours (Wh)
	| ac/is_valid | R | Indicator whether all enabled inverters where reachable | 0 or 1 |
	| dc/power | R | Sum of DC power of all enabled inverters | Watt (W) |
	| dc/irradiation | R | Produced power of all enabled inverter stripes with defined irradiation settings divided by sum of all enabled inverters irradiation | % |
	| dc/is_valid | R | Indicator whether all enabled inverters where reachable | 0 or 1 |

OK got it. Thanks!
