Request for Energy Consumption

[moritzschrader]

Hi guys,

I recently discovered that my Webserver UI also displays the consumed energy in kWh ("Eingesetzte Energie"). I'm posting the xml response I get after login below.

I was not able to find anything resembling the values when dumping all calculations and parameters (also tried the bouni python version). Was anyone able to find it and could we add it here? Are they maybe encoded in any other way?

It also would be great to have the current power consumption, if anyone can find it. I know I could also take the time derivative of the energy in kWh, but that is quite slow/delayed. Instantaneous power would be amazing!

Thanks for any help, love what you've done so far!

Hello @moritzschrader. This Node-RED node is using the excellent smartmeter-obis module to parse all the data from smartmeters. So the work has to be done at the smartmeter-obis node. Also it would be very helpfull to know which smartmeter you are using.

Hi @coolchip, as far as I understood, the heat pump has a rudimentary power calculation by itself. There's no smart meter connected to the heat pump.

I think then this is the wrong node for you. Perhaps there is a dedicated node for your heat pump.

Hello,
@moritzschrader is right, the the new Luxtronik2 FW which is read by this Module, will cover power consumtion in addition. There are lots of user without powermeter in front of the heatpump. So it would make sense to have that featcher request to Luxtronik. As you can see the registers are already offeren by a web session to Luxtronik.

I already did a short test and compared my powermeter against the internal calculation and it looks simular, if you do it on a base of kWh.
