Incidentally: after working from home since the start of the pandemics, I feel the need to actually monitor myself as I often lose track of my working hours and I have a suspicion that I work longer hours than previously. Related to that, less amount of movement/exercise. My plan is to monitor the situation with simple Raspberry Pi zero based project - add a current sensor (to sense if my main display is on/off) and a distance sensor (to see if my standing desk is up/down), store the data in local time series database and present in local Grafana (no way I am going to put this outside my home network) with the possibility of alerting via PagerDuty.
