You said “set up a nodemcu v2 with a HC-SR04 proximity sensor and a DHT11 T/H sensor in my garage using OG v1.1.0.” — so I assume this is using your own hardware and not purchased from us? Also, did you modify the firmware yourself? The stock firmware does not send T/H readings to Blynk, and you said it stopped updating Blynk. If you modified the firmware yourself you can turn on debugging by uncommenting the #define SERIAL_DEBUG line in defines.h
