Hallo Kees,

Yes i found it thank you verry much!!!!.
where did you attach for example Burner on/off to because if i attach it to an switch i can control it and i want to read.
or does it turn the switch in the dashboard on if burger gets enabled?

kind regards patrick

Yes use a switch sensor.
The switch in the dashboard does nothing if you toggle it by hand. It only reflects the state of the 'burger' as you called it. :-)

Hallo Kees

nu heb ik nog 1 vraagje (:
the switches are working i tested it trough enabling my heating but at the domoticz idx numbers you have IDXhotwater and IDXboiler but i dont get value at both of them not as switch and not as tempratuur.

kind regards patrick

Yes it seems I forgot to add the code fragment for the IDXboiler HTTP request.

IDXhotwater is in there, but it will only send the value if it has changed.
If you turn on the hot water for only a short moment, it can miss the change in value, so turn it on for longer and it should send the change to Domoticz.

Hi Kees,
I am also working on the Nefit Topline Aqua Power (Ketel + Boiler) with Arduino Mega (+ EMSBusInterface) and Domoticz. The reading with sketch from EMSBusReceiveExample1 is fine. All values are read correctly. But I do not find all IDxs and values in Domoticz.
I only see 6 of the 8 IDs. The boiler temperature and the hotwater temperature do not occur in Domoticz, the other six do. What is going wrong here? Wrong setting? What should I adjust?

You mean that you have created the sensors in Domoticz but the boiler temp and hot water are not updated?

Are you sure you created the right sensors and use the correct IDX numbers?

The boiler temperature is in the default datagram from the boiler so if all other values are read out correctly it means the problem is likely somewhere else.

Hallo Kees,
the output on Arduino Mega Serial Monitor of EMSBusReceiveExample is good. But i get no value from nefitRegister[5]:558 into Domoticz. I transmit the output via Ethetnet shield to the Domoticz server on my pi+3.
I set my own Domoticz Idx number: int IDXboiler = 006; //ketel temp. But there is no result or value (55.8) in Domoticz with IDX 6. I have a Nefit Topline AquaPower en Moduline 400. Do you have any idea what is going wrong?
