The main purpose of the E-Maxx is to connect to Selectronic SP Pro, collect data and display this via a mobile phone and / or website.
The E-Maxx also allows clients to remotely connect Selectronic SP Link software with the E-Maxx. This is more for diagnostic / support purposes than for monitoring purposes. Also configuration changes can be applied remotely by approved owner and installers.
