Hello,

Since I'm using the pump in Heating Flow Temp mode, can you add theese 2 sensors?

Hi, the water feed and return temperature is present as sensor. If that is not enough, can you detail what you want to have? I have added all the data known to me to the integration, so I'll need the address, offset and such

Hello, I am talking about the space heating flow feed and return temps, not the ones that are on the HP itself. They're connected to THW1 and TWH2 on the board. I have them because I have a mixing tank for space heating and its flow tempsare not the same as the HP flow temp. I don't know the address and offset, but this project has it: https://github.com/rbroker/ecodan-ha-local/tree/main. The 2 sensors are Boiler Flow Temperatre and Boiler Return Temperature
