Hi,
I try to verify the temperature of hotwater. If below 60 degrees the power controller should be adjusted to 90%. in my node the output is always 90 degrees and so the 0-10V KNX device will not understand it.
I use the cange node to set the value to 90:
Without seeing your flow and the msg you are processing it’s hard to give you advice. Please export your flow and attach it to a reply and add a debug node ( set to display the complete msg object) to the output of the switch node and show me what it is.
The temperature is checked if <55 degrees and then set true. Depending on the azimuth of the sun the contactor will be activated.
The difference between PV power and used power controlls the amount (0-10V) of the power controller. If the difference ist greater than the power of the heating it ist limited to 90%, if it is less than 1 kW it ist fixed to 20%, and between adjusted linear.
