Ageon WebFi | Monitoring Gateway (Black Line Controllers)The WebFi module can be used to add connectivity to any of our Ageon Black Line Temperature And Humidity Controllers. This device requires no external power supply, it simply plugs in to the controller USB port and can then be configured via Bluetooth. After initial configuration the WebFi module remains connected to a local wireless network. The main advantage of the WebFi module is it provides access to Ageon's cloud based service known as ArcSys.
