Nilan

This app adds support for Nilan Heatpumps, such as EC9 - running with CTS602. App uses TCP Modbus for communication though RS-486a. For TCP Modbus connection, a bridge device is required; I personally can recommend cheap Elfin EW11, which works very nicely and has proven for me to be stable. It also accepts +12V provided by Nilan's heat pumps. App is very comprehensive and provides a lot of sensor data. You also get to control temperatures, humidity and modes of device - and can also do this with flows if you choose to. This app was built on top of already existing SystemAir app by Bjørnar Almli, so thank you for that, propably couldn't have built this without his work.
