I have nodemcu and atmega 2560. both are serially communicate.

when DHT is send it value to atmega it will serially transfer the value to nodemcu and after that the nodemcu sends to Widget

but the temperature value is shows on GUAGE WIDGET Not HUMIDITY

also i open the serial monitor both value are showing in that but not in Blynk app’s widget.
