How often are you people screwing things up so badly that your servers aren’t reachable over the network and require keyboard/monitor access? This is basically only ever once for me for the initial OS install, and even then that can be automated away if I had to do it more than once every couple years
I’ve had a withings scale for like 5 or 6 years, use trendweight.com for a graph, I haven’t had any problems with it besides replacing the batteries every year or so
