Data Loging and Trending
Am I correct to assume that if a polled point does not change from the last sample, a new pointvalue is not going to be persisted to the DB? I got an HTTP retriever going out for weather and it does not change much from that source. The mySQL db has the just first sample.
From a trending perspective I trend internal temp with external temp. Until I set up a temp sensor outside, the external site will do. The issue is that the slow changing temp is not interpolate along with the other trend. Even as a single trend for external temp, I would expect a horizontal trend line. I get a single point.
I can live with that constraint for now and implement a different charting approach to deal with interpolation.

Your logging type is probably set to "on change". Change it to "all".
Thanks. I know I did it once--I just installed Mango a couple of days ago--but forgot how to get there.
I'll get used to the UI navigation.
BTW, nice work.
