# ESP MQTT DHT
This is the script for my [mqtt-smarthome](https://github.com/mqtt-smarthome/mqtt-smarthome) based Temperature Sensors (DHT22).
It is running on a NodeMCU board (ESP8266).
The basic source code was inspired by this [repo](https://github.com/titusece/ESP8266-MQTT-Publish-DHT11)
## Installation
In order to build this the Arduino tool was used.
### MQTT Server
As an MQTT server I use a Raspberry Pi with `mosquitto`.
It is in the Debian repository (which includes Raspberry Pi OS) and can easily be installed: `sudo apt install mosquitto`.
Make sure to allow anonymous (and enable the default listener on 1883 if you also want web socket support)
```conf
listener 1883
allow_anonymous true
```
### Prepare Arduino
Set the following under File → Preferences → Settings → Additional Board Manager Urls (hit the rightmost button to open the Window):
```plaintext

https://dl.espressif.com/dl/package_esp32_index.json
```
