Recently purchased the kit and have it assembled.  Successfully compiled the code and uploaded to the Wemos.  When the Weather Station starts up, it goes into touchscreen calibration mode.  It presents the white dot in the upper left corner, but no amount of pressing on the dot (or anywhere on the LCD screen) has any effect.  i try using both my finger and the included stylus to no avail.  Any suggestions?  Defective LCD?

All LCDs are tested before they land in the kit to ensure they work as expected i.e. we don't rely on the manufacturer's QA. Hence, unless it got damaged while unpacking it's unlikely the cause here. Judging from past experience I suggest you first check for cold solder joints - particularly those going to the touch controller. At https://docs.thingpulse.com/specs/wifi-color-display-kit/#wiring we documented the wiring diagram.
