DHT22 example does weird things

[adnidor]

Don't have the time to look into it atm, code can't read sensor value (may be pebcak) and transmits invalid JSON via MQTT.

MQTT DEBUG Received iot_input b'{"ud-dht22.temperature":%.3f, ".humidity":%.3f, ".errorCode":1073644376}'
MQTT WARNING Error decoding payload: Expecting value: line 1 column 25 (char 24)

Hmmm, there seems to be a invalid value inside the data vars. Unfortunately, I have very few time too, but I try to fix it.
