Netonix switch firmware upgrade

Recently firmware v1.4.7 became available for Netonix WS-150-DC. One of my favorite enhancements is the auto scaling of the input voltage graph (see image below). Before the range was always between 0V and 60V which made a 3V change during a few hours of the day very hard to see. But not anymore! This feature comes just in time to make some changes to account for the shorter days and lower temperatures during winter. As you can see the Voltage is dropping dangerously close to 24.7V The manufacturing recommends to not go below 50% if possible of your battery capacity. Which would be 24.7V in my case (see my explanation here).
