1 Motivation
Oer the time I have found out that my DB0MHB Arduino Monitoring Device stops working over several weeks or months. The period when it fails varies. Sometimes the device runs perfectly for months, sometimes it fails after just a few weeks of operation. This is a nuissance, but I cannot diagnose it because over such long time periods it is practically impossible to isolate the cause. I have found out that it is still possible to ping the device, but the web server will not produce any output.
The solution is to physically go there and reset the power supply.
Since this solution cannot really be a solution, I decided to automate the powercycling with another very little Arduino, the Arduino Pro Mini.
