Automatic firmware check

Do you already know the function "Automatic firmware check"? By activating this function, the Solar-Log™ device (possible with firmware 3.0.0 and higher) searches daily for new firmware versions on our update server. If a new version is available this is displayed accordingly. After confirmation, the firmware can be downloaded. The prerequisite for this is a functioning Internet connection.
