Thank you! I was having problems reading again after the first read, but it is fixed now. I can confirm that the module works with DHT21 (AM2301) also.

- Mon Feb 02, 2015 3:56 am #8754 By adding floating point NodeMcu the latest versions of many scripts have stopped working properly. The module for DHT22 was affected. I made an update to work with or without floating point. Also I changed the error control, now the error is indicated with humidity = nil (before humidity = -1).

The example also been updated
