Display temperature and status of heat pump, heating and hot water of heat pumps controlled by the Alpha-InnoTec Luxtronik 2.0 controller. This is an OSS alternative to the controller-provided Java applet, which does not work on mobile devices. You must be connected to the same network as the controller (so for remote access you may use a VPN connection into your home network). You can currently only display values, not change settings. Notice: The purchase price is to protect against uninformed use ("Schutzgebühr"). The source code is freely available on GitHub (see the Website button).
