MMM-DHT22 Humidity and Temperature Module

@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 -
@DocVooDoo well, no idea then… Have you tried to run the normal version (instead of the serveronly)?
-
@ryck yes, the same problem…
-
@ryck is it possible that the module root rights needs but does not get?
with another module comes the same error. root privileges are needed there
