Raspberry Pi

My First Pi3 is up and running since 2016 24x7 without any issues. I have a second Pi3 as test and backup/failover device. A newer Pi4 I am using as kubernetes cluster and a Pi400 as sandbox.

use cases:

FHEM
vwmon (Vailant Heating unit monitoring)
unifi controler

webserver
k3s cluster
prometheus
grafana
fritzbox monitoring
