What kind of information do you need more? What shall I add?

[proddy]

Have a look at https://docs.emsesp.org/Troubleshooting/#im-missing-certain-data-from-an-ems-device

See if EMS-ESP detects the device on PKS9, if it's indeed an EMS device. It'll be shown in the logs. Then we'll need to help to decipher the telegrams. What kind of information do you want to see? Can you make screenshots of what is displayed now?

PKS9 is connected to heatpump via CAN, it is not a EMS-device, so you'll get no device and no entities. Maybe some options in the UI/thermostat change to support cooling.

PKS9 has two Mixing valve actuators (Brine & Heat carrier) and two Flow temperature sensors. It is very similar to MM100 logic.
