In the past few days I've soldered two Heatermeter (v4.3) boards.
One of the two worked as expected. The other, on the other hand didn't. Only the left button works. Any other key does not work individually.
When I combine Up+Right(+Down), I get a right-button response.
Looking at the ADC readings for the buttons of the two boards, I get the following:
As a electronics-hobbyist, I tried to check the soldering and did not find any major differences between the two.
Question:
Did anyone experience something like this? Looking at the forum (and Google) I couldn't find info about this topic, other than the Basic Troubleshooting for the Heatermeter.

Working | 137 | 78 | 41 | 174 |
Not working | 108 | 61 | 32 | 137 |
