Keep the ESP separated from the DHT — or else the heat from the wifi module affects the temperature and humidity readings.
### Setup
Flash your device and it will create a wifi network called SimpleWeather. Connect to this and wait for the captive portal, or visit 192.168.4.1 to set up. Fields are:
1. Wifi network to join
2. Wifi password
3. MQTT server address
4. MQTT server port
5. Temperature topic
6. Humidity topic
If your ESP device needs clearing out (old wifi credentials, etc) then set `resetWifiSettings` to true. Flash and let the device restart, then set it back to false and reflash again. Re-run setup.
