I have uploaded measurement logs from my RuuviTags for some time, and now have a mixed collection of logs from iOS and Android devices. Sometimes one device had the most recent or most complete log, sometimes another one had.
I have writing a Python program to merge logs together, still working on it. One problem is random mistakes, e.g., air pressure of 10000, easy to detect, but a more difficult is smaller random mistakes, and their automated removal.
Also the file formats have frustrated me. They have changed a few times since I got my RuuviTags. I hope the formats will settle to
-something common for iOS and Android
–including or not the sensor name in the file itself
