Hello,

Can’t handle this problem by myself. Maby some one can help here?

I have new “Wemos D1 mini v2” with ESP8266-12F on board and “Wemos DHT22 Shield”.
It should work “out of the box” but it does not.

I think the board hase 10kOhm pullUp resostor allready soldered?

I’ve cheked differet GPIO’s, all my solder joints, all connections,my device if flashed correctly.
I can find it on ESPHome, it is discovering DTH22, but on the end of line im getting this:

[20:08:27][W][dht:126]: Requesting data from DHT failed!
[20:08:27][W][dht:060]: Invalid readings! Please check your wiring (pull-up resistor, pin number) and consider manually specifying the DHT model using the model option.

[20:08:27][D][sensor:092]: ‘Hum_out’: Sending state nan % with 0 decimals of accuracy

And non of found on the web solutions helped me ,it default send signal from dht22 by D4 line, I also tried to bypass D4 and and use direct solder. …and nope…

What I’m missing?
In HomeAssistant my entitie get: Unavailable

This is my code for ESPHome:

esphome:
  name: sensor_kkn
  platform: ESP8266
  board: d1_mini

wifi:
  ssid: "My Wifi"
  password: "My Pass"

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Sensor Kkn Fallback Hotspot"
    password: "9xw9e5w4Uj84"

captive_portal:

# Enable logging

# Enable Home Assistant API
api:

ota:

# Example configuration entry
sensor:
  - platform: dht
    pin: D1
    model: DHT22
    temperature:

    humidity:
      name: "Hum_out"
    update_interval: 30s

And this is output log: (here is for D1 pin but i get this on all tested GPIOs)

Please give me some advice.
