MMM-DHT22 Humidity and Temperature Module

@PaulB - glad you have found some time to work on it.
Yes I still have the problem with reading the data in the MM.
Hope you can find the cause. I would like to help you, but i’m not a programmer.
The only thing I could help on is perhaps some beta testing.
Cheers.

Hey, i have the same problem.
With “./Adafruit_Python_DHT/examples/AdafruitDHT.py 22 27” comes the Temperatur “Temp=20.1* Humidity=29.3%”
The DHT22 is Pinned on PIN 13 (27) (WiringPi 2). On the Mirror is the Temperatur and the Humidity undefined.
Whats the Problem? I found nothing… -
@DocVooDoo Then I don’t know, maybe there is something wrong with the module…
Have you tried mine? https://github.com/ryck/MMM-DHT-Sensor
-
@ryck Hi. yes, a minute ago. He says “no data returned”.
-
@DocVooDoo sometimes the raspberry pi needs some time to pick up the values… try to increase the update time (ie, 30 seconds) and wait for it to update a couple of times…
-
@ryck nothing has changed. i have “node serveronly” running, and the log says “Error: failed to read sensor at Error (native)”
but the sensor works…
-
@DocVooDoo Weird… did you follow all the instructions? ie, install bcm2835, npm install, etc?
-
@ryck Yes of course.
-
@DocVooDoo No idea then… Can you paste here the error you get?
-
@ryck only this
then nothing on the log in node serveronly screen
