Domoticz

As many (dutch ?) domoticz user i like to optimize my heating system.

Now i caculate/measure in different sensors the temperature from the heating system (in, out and dT) and bassed on this i calculate the effeciency of the heating, and wrote a small script to plot the gasflow (ltr/min) every 5 minutes.

I really would like to have the gas flow, effeciency (results of the water in temperature) in 1 graph.

Is there a way to do this with DZvents ? ( I know domoticz doesn't support this out of the box, but may something smart with a json string.. ?)
Is there a way we can directly interact with the " High Chart" module ?

I would not know of a way to do this in domoticz. Retrieving the information and do the calculations with it is not the problem but to get a graph with the combined datapoints plotted within domoticz a special device would be needed which is not available.
The closest you can get to this is to send the data to influx or another external database and have a kind of graphical interface to it.

Yes, the work aground (grafanna for example) is an option. But find this a little bith a pitty.
Also looking to the source code, it is nearlly inside domoticz.
Looking back this request is poping up since years.

Since Domoticz make use of hte High Cart module, can it be made in the custom tab ?
Never dive in to this, or could we (worst case) make a " grafana" webpage which we can put in the custom page ?
