touch display problem

Hi to all,
I have started with this project abouth month ago and I have lot of problems. I am not an EE geek or electronic or programmer so thi is normal for me .
The touch works - responds if I connect to 5V powersupplay but vont respond if 9V is connected.
Other thing is that with 5V wifi module is not vorking while there is onla 2,3V. With 9V the module blue LED is blinking (red is on) but no connection to my router. In sketch terminal window I have multiple errors.
Can someone look to that?
Regards

Ihave tested vith 5V 800mAh and 9V2A.....
Problem stays...

It is possible that problem ocours while I have 1.0v LCDTFT schield instead 2.2v (2.3v)?

Sadly to say, I encountered the very same issue. Did anyone find a solution in the meantime?

Yeah, a friend of mine have found out that power pin hasnt been soldered (!) now works fine. It wasnt be on wisiblw side...
Now touch display works fine. The problem was also because I have diferent watch-clock and couldn't be adjusted.
Other problem I have was the BMP sensor, I have 280 instead 180, which also don't want to comunicate wright.

Now I have hardware working, been too fast and erase sensor in the T-cloud and now I am unable to connest it again with cloud service. Could someone help me hov to add MT-thermostat again? or resset the cloud...
