Home Assistant DHT temperature and humidity sensor

This is a spin-off from the official home assitant DHT integration, which was removed since Home Assistant Core version 2022.4.0.

The dht sensor platform allows you to get the current temperature and humidity from a DHT11, DHT22 or AM2302 device.

Installation

HACS

The recommend way to install dht is through HACS.

Manual installation

Copy the dht folder and all of its contents into your Home Assistant's custom_components folder. This folder is usually inside your /config folder. If you are running Hass.io, use SAMBA to copy the folder over. You may need to create the custom_components folder and then copy the dht folder and all of its contents into it.

Setup

To use your DHTxx sensor in your installation, you must first install the libgpiod2 library.

sudo apt install libgpiod2

Configuration

Add the following to your configuration.yaml file:

# Example configuration.yaml entry
sensor:
  platform: dht
  sensor: DHT22
  pin: 23
  monitored_conditions:
    - temperature
    - humidity

The name of the pin to which the sensor is connected has different names on different platforms. 'P8_11' for Beaglebone, '23' for Raspberry Pi.

Example

An example for a Raspberry Pi 3 with a DHT22 sensor connected to GPIO4 (pin 7):

sensor:
  - platform: dht
    sensor: DHT22
    pin: 4
    temperature_offset: 2.1
    humidity_offset: -3.2
    monitored_conditions:
      - temperature
      - humidity
