DHT11 Error

Guy ZED — Sun, 21 Dec 2025 14:08:08 -0000

Hello,

I try to build a DCP3

For the moment I work on a bread board.
And I have an issu with the DHT11.

It wired on pin 4.
I have an Oled screen too (oled work)

But I have a DHTxx error (some times I have temperature and humidity, not often)

I try with the TestDHT.ino (changing DHT22 to 11)
It doesn't work.
I also try with an another lib with a test code. And this time I have humidity and temperature.

My wiring seems good.

Have you a way to give message ? Because I'm stuck.

Best regards

I got some Errors with my OLED display here.
It seems the screen is rotated some pixels to the left. You will see a dirty line on the right side of the display and on the left there are some pixels missing.
You have a SH1106 OLED! They are working a little bit different.

In "displays.h" change
myoled.begin(&Adafruit128x64, I2C_ADDRESS);
to
myoled.begin(&SH1106_128x64, I2C_ADDRESS);
and it's solved!

Greetings, and thanks for this nice project!

I jave taken a look at them. The ones I saw have a USB connector.
You would have to cut that off and fit a differnt connector compatible with the project.

The current specifications for the straps look a bit higher than dew not straps, but since the dew controller uses PWM it should be ok. AS LONG AS - this is important, do NOT use the 100% override with the Svbony straps

HI Robert,

I have submitted the pull request, but have got stuck at creating the driver listing on indilib.org. I can add a listing with basic detail, but cannot add any details. I am trying to contact indi for help.

I have attached the screenshots of the driver tabs in Ekos
