Good Hi, I'm new to HG.
I have a problem with DHT-22 module, this module when fed from raspberry to 3.3 v, works almost well, although the module tell him to update every 600 seconds, every 3 seconds ago, that I do not care what matters to me is that the working hour is blocked and does not update. until I disconnect the feeding of DHT-22 and return to work.
Not how to fix it, thank you very much and goodbye.

PS is not English, is a translation of google

Hello there,
I use 1.1 beta r5.11a My DHT22 no longer operating correctly. Start the program, I will measure the temperature again. Then not again. Only when I restart the program, a measurement again. An automatic query is no longer made.
Thank Thoralf

Hello there,
have tried to compile the program for the DHT22. Previously had not changed. Nevertheless, when compiling the error message "Error  Input string was not in the correct format"
I also compile the GPIO port Error message when.
Has teamed up with the new versions (from 1.1 r509) what changed?
The DHT-22 program has certainly a problem. Does anyone have experience on the subject? Thank you!!!

Again DHT22 module stop`to 22:40, an average solution that I will do, is put a relay in the power of DHT22 to reset it.

Hello,
the program DHT22 (63) is simply not start. In the complex you can see my screenshot.
Today I downloaded the version 1.1 beta 512th Unfortunately, there is no change. The sensor is fine because the restart of HG, the temperature is measured 1x. Then no longer.
A kompiliren the program 63 also leads yes to an error message.
Can anybody help?
Best regards

Hi, all

My DHT-22 and 2x DS18B20 all stopped working after upgrading from r509 to r512, after rebooting the Raspberry PI 2.

Running Jessie.

Issue must be within HG, as I can see both DS18B20 when I run LS command from Terminal.

Any ideas?

Hi, all

Good news: The issue with my DS18B20 sensors are resolved. Was my mistake: I changed the time in program from 600 to 60. Not sure where my mind was. Have set back to 600 and working perfectly now.

Thanks, all.  :)
