I'm testing something now... I've put the over-high puck into freezer for a minute (went down to ~15 deg). I've then put them together on a table and let them "settle".
The second puck has also been triggering button presses when I picked it up, or when gently tapping it (without the click, just vibrations).
I've since reset it again, uploaded my code again and let it settle with temp. I now have around 3 deg difference between them, which is not bad. I'm calibrating them now with a primitive thermometer.
I'll try to get a more accurate one and calibrate them both again, and see if I get this weird behaviour again.
I'll report back. Thanks!
