Thermostat controls for the NGBS iCON surface heating/cooling system. Note that this is not an official app from NGBS, but developed by an NGBS iCON user.
Currently, the app needs the iCON controller to have a fixed IP to function correctly. This is because there is no known discovery method the controller supports (Homey supports mDNS, SSDP and broadcast ping based discovery, none of which work). The web API (used by the mobile app) would be a potential alternative, but it's probably not suitable for 24/7 continuous polling.
