I can not add the DHT (Adafruit) Lib to Wemos D1 8266 Plattform

#1

I try to use the DHT Lib from Ada, but I always get an Error 1…

Here the log:

Do anyone have a solution for this issue, coz I can’t find any in the web…

#2

This shows up with PlatformIO Registry. So try adding that library? In the project’s platformio.ini file, you should have both libraries:

lib_deps =
     adafruit/DHT sensor library @ ^1.4.3
     adafruit/Adafruit Unified Sensor @ ^1.1.4

and also make sure that you main sketch file at elast includes DHT.h so that the library dependency finder is triggered to search for all its dependencies.
