So I backed the 20$ temperature sensor version. I received the following version shown in the picture today (12 April 2017). After reading on the forum I am aware there is a Temperature sensor version and the All sensor version.
Could someone please clarify this is the temperature sensor version. I’m noticing the BME280 chip missing.
Is there difference between full version and this temperature sensor version about pre-loaded firmware? While I was heating up sauna yesterday, i didn’t manage to get any temperatures, and while I was without stable internet connection, didn’t found proper documentation how it shoud work. Now when I can open video tutorials, it seems that I will need to update firmware somehow to get temperatures
