On may 25th, 2017, posts pertaining to temperature logging were compiled into this separate thread. You may see remnants of other threads in the first few posts.
something completely different: I am working on an app to capture the actual room temperature and the programmed temperature level for the last 24 hours (rolling).
I keep an array in memory with the data points in intervals of 10 minutes. I noticed that at 04:00 (03:00 system time on my Toon) all data from memory is cleared.
Does anyone know what is happening at 03:00? I also noticed a lot of logfiles are written at that time but they do not contain any serious warnings/errors.
The workaround will be to write the 24h data to a local file each time but I am just curious what is going on.
