I use this PI regularly. One of its uses is to track the hot water temp through my hot water recirc system. Sometimes however, it misses when a device activated. For instance if someone gets up in the middle of the night to go to the bathroom, the motion sensor turns on the recirc pump. By the time they finish their business, the water to the faucet is nice and warm. The pump only runs for a minute and 15 seconds.
The problem is that in the chart, the water temp gets recorded but some of the pump cycles are not getting recorded although it is coming on and it is in the log as such.
So the question is "Which database update mode would be better to use?" Right now I have fixed timer 10 minute referenced to minute. I've never really understood these since it seems whatever I've picked gives me usable graphs, until now.
