Wrong temperature on the main screen of color weather station

Question

Hello,

Today I received weather station bought here:

https://www.aliexpress.com/snapshot/0.html?orderId=87274080225716&productId=32836372386

Generally after configuring it works, congratulations for very interesting project, but I have a problem with temperature shown on main screen: it is wrong. Despite I'm reading correct temperature from wunderground (checked by link given in settings.h) and it is correctly shown inside screen "current conditions", on the main screen I have wrong value. Both screens you can see here:

Anyway, now as I see, aliexpress sells this device with or without touch screen. When I bought my own (one month ago), there was no such choice, but price was equal to present "with touchpad". How can I check if my device has a touchpad or not? The most obvious method "just touch and check" tells me "not", but maybe it needs to be configured for working?

Thanks in advance and best regards

Jarek

Answer 1

I solved this problem by own, reason: not commented LM75 in settings.h.

But anyway, I'd like to ask, where I can find more detailed description of this hardware (AZSMZ), especially destiny and pinout of connectors.
