I am not sure, if I got you correclty.

 

You have a quickapp that listens to your energymeter values in every 10 sec? So i assume it is a loop that calls the energymeter device by hub.getValue(energymeterID, value) -- here value can be power, or whatever you are listening to

 

and using

will always save the value_in_joule into the quickapp device's value property. So when it is once saved, you can test it by hub.getValue(self.id, value), or you can see it in dashboard when pressing preview button..

The question is, when and how is your updateProperty function called...Is it inside some event listener function that reacts to every change of your energymeter change?

If so the newly recieved value will overwrite the value property and will not add up..It will just update..If you want to sum them up, you do

I am still a bit confused, what you want to achieve, but lets try...

 

So your incoming values are in Wh right? These values are stored in your energy metere type quickapp value property

Energy meter type device will always keep data in kWh, so whatever value you store in it, it will be handled as kWh..

So the overall Fibaro energy panel will always consider values of this device as kWh..whatever value you will have there...

So if your data are coming in Wh, you should convert them to kWh, using the formula: 1 watt hour = 0.001 kWh.

 

Your other part of the question:

"The value after 2 hours changes, becoming 11702360. If I understand correctly, the data is updated"

 

Well this is what i dont get..Data are coming from some device into your energy meter type quickapp right (from some resource)?..If so, your energy meter type quickapp should handle the update..that is something you should write into it, as i wrote you..

The enery meter type quickapp is still only a quickapp...it will do nothing on itself..you need to write the code in it, that will update its values according to incoming values..

So you need to write the code

and that value should be in kWh, to be correctly handled in FIbaro energy panel
