callifo, great input.
I purchased an opengarage in October, it started failing with false readings at the end of the month as the weather cooled.
After some discussion, I sent the opengarage in for testing, they could not replicate the issues, and sent a new unit back.
The new unit has started to have the same symptoms and I am experiencing colder weather again.
I just swapped out the usb power brick (oops, it was a knockoff iphone charger) for a 1 Amp one that came with an amazon fire tablet.
Hopefully that stops the false readings.
If I don’t follow up in this thread… assume that worked 😉
