This is how I'm logging;
I was using WirelessTags which were pretty accurate, but I had to run that through ST and there was a 5-10 minute lag between. Then a few days ago, the software just started tanking and now I can't get them to calibrate for the life of me. I started the latest round of the temp adventure to finally get off of the ST hub (WirelessTags were the last thing holding me there).
In removing the delta between the rooms, the HVAC seems to run a bit more often (winter and summer) but not as long, and I'm not pushing air to the east side of the house during the summer that's needed on the west side. I also drive a house with them during the summer so keeping a reasonably accurate read on the bedrooms keeps that fan from running more often than needed.
You may want to research the Zoos some more. Will applying constant power increase the reporting period (as it does with Aeotec)? Another thing is related to what there accuracy is measured in. If it's accurate to 1 degree C, that's still somewhere between 1.5 to 1.8 F difference. It's these little things that are driving my ADD tendencies up a tree.
For the last few hours the Aeotec has been pretty spot on. It'll take a few more days to get a better collection of data, but I'm pretty impressed. I'll post a multi day graph once I get the data.
