Hey,

i just received my DHT22 and startet to connect it to the pi.
For connecting the sensor i followd this tutorial.

with the supposed command

Code:

sudo ./Adafruit_DHT 2302 4

i get temperature values, so i guess, that the wiring and the sensor itself is working.

here's my config. I integrated it in my complete config and i can start the service without any problems.

Code:

"DHT22": {
                        "name": "Temperatur DHT22",
                        "protocol": [ "dht22" ],
                        "id": [{
                           "gpio": "7"    
                        }],
                        "humidity": 0,
                        "temperature": 0,
                        "settings": {
                            "interval": 5
                        }
                }

I do not get any updates and i don't have any idea whats going on.
Did I miss something or whtas wrong here?

best regards and thanks for your help

EDIT: Here's the right code, when the sensor is connectoed to wiringpi #7:

Code:

"DHT22": {
                        "name": "Temperatur DHT22",
                        "protocol": [ "dht22" ],
                        "id": [{
                           "gpio": 7    
                        }],
                        "humidity": 0,
                        "temperature": 0,
                        "settings": {
                            "interval": 5
                        }
                }

The adafruit command you posted suggests that the dht22 is connected to GPIO 4, your pilight config is pointing to GPIO 7. What pin is it the dht22 connected to?

[IcedEarth]

Hey, i connected the sensor to GPIO #4 (so wiring pi 7)..

[meloen]

Try wiringpi #4, based on http://wiringpi.com/pins/

[IcedEarth]

Changed the wiring, but don't get any signal in pilight. Using the command from the tutorial, i had to change the pin to 23 to get results from the terminal...

You're mixing BCM and wiringPi pins.

[IcedEarth]

well.. pilight uses the wiringpi, so when i connect the sensor to the wiringpi #7 (BCM 4) the config i posted above should do it's job, right?

[curlymo]

I found the issues. Carefully compare your config with the example here: http://wiki.pilight.org/doku.php/dht22

[IcedEarth]

ah yes - i found it, too. Damn quote signs

with

Code:

"DHT22": {
                        "name": "Temperatur DHT22",
                        "protocol": [ "dht22" ],
                        "id": [{
                           "gpio": 7    
                        }],
                        "humidity": 0,
                        "temperature": 0,
                        "settings": {
                            "interval": 5
                        }
                }

it works fine.
Sry for my blindness - i think i just looked too long on the code.

You can close this thread.

Thx for all your help.

Is it possible that you've forgot to add the gui-show-humidtiy in the .c of latest commit for the dht22?
