Unfortunately the DHT22 is notoriously flaky, and can only be read a maximum of once per two seconds under ideal conditions. This is a limitation of the sensor, and its price point. You can try increasing the duration of the initialising runs back to the default of 15 seconds, but we still see this error on all of our units occasionally I'm afraid.
