Please look at this screenshot: Unfortunatley, just before I made this screenshot, I had to restart the cumulus software, but I had in mind, that it ran since September 2017 .
Anyway, this small piece of hardware - RaspberryPi 2 with an internal SD Card is up since 382 days and until today, there is no need to restart it......so I am looking for the next 365 days Uptime.
Btw: A great thanks goes also to Steve, who made this very stable piece of software.
