About

Not only human performance is monitored but also the system performance. The system consists of a couple of raspberry PI minicomputers, 2 x 433mhz rfxcom antenna’s and about 30 hue lamps connected to 2 hue bridge. The hue lamps, wireless switches and motion sensors are polled every minute for reachability. The system will alert me if something is failing and I can take action (but it honestly doesn’t happen very often). he info on this page reflects only part of the data that is being logged but will give you a pretty good impression.

Raspberry CPU temperature

Raspberry CPU temperature is not only influenced by workload but the ambient temperature has a big influence I noticed.

Philips Hue network reachability

All the lamps and switches are polled every minute for their reachability. Usually the score will be a 100%. 
Sometimes when by accident a plug is pulled then the score will be lower. In that case an alert will be sent.
