Novelan/Luxtronic Heat Pump Binding

This binding was originally created for the Novelan heat pump. Since the Novelan control unit is based on the Luxtronic 2 contol unit of Alpha Innotec, this binding should work with all heat pumps that use this type of controller.

Note: The whole functionality was reverse engineered via tcpdump, so use it at your own risk.

These parameters can be changed:

  • Heating operation mode
  • Warm water operation mode
  • Cooling operation mode
  • Offset of the heating curve
  • Target temperature for warm water

Prerequisites

The heat pump bundle connects to your heat pump via network. Make sure your heat pump is connected to your network and the network settings are configured. To access the network settings go in the heat pump Service menu -> system control -> IP address.

Binding Configuration

This binding can be configured in the file services/novelanheatpump.cfg.

PropertyDefaultRequiredDescription
ipYesIP address of the heat pump to connect to
refresh60000Norefresh inverval in milliseconds
port8888Noport number of the heat pump to connect to Please be aware that from firmware version 1.73, Alpha Innotec has changed the port to 8889.

Item Configuration

The item configuration format is simple and looks like this:
