$10 DIY Smart Home Temperature and Humidity Sensor with a NodeMCU, DHT22 and HomeAssistant

This video will teach you how I built my temperature and humidity sensor using a NodeMCU, DHT22 and Home Assistant. Here are the products I used in this video: Raspberry Pi 3 - https://amzn.to/2XQK06A NodeMCU Microcontroller - https://amzn.to/2VSwLkc DHT22 Temp and Humidity Sensor - https://amzn.to/2NYplJj Follow me on Instagram @SmartGrowAutomation Here is an overview of the steps I took in this video: 1) Get home assistant up and running https://home-assistant.io/getting-sta... 2) Install Configurator and Mosquitto 3) Make mqtt_admin user 4) Get Arduino IDE setup: https://arduino.cc Drivers: https://www.silabs.com/products/devel... Additional Board Manager URL: http://arduino.esp8266.com/stable/pac... Four libraries to install: ArduinoJson (v5), PubSubClient, DHT Sensor Library, Adafruit Unified Sensor 5) Wire up DHT22 to NodeMCU (+ to 3.3V, - to ground, out to D2) 6) Edit source code with your wireless network info and upload. https://gist.github.com/SmartGrowAuto... 7) Add sensor to configuration.yaml and restart home assistant: sensor 6: platform: mqtt state_topic: 'dht22-3/sensor1' name: 'Temperature2' unit_of_measurement: '°C' value_template: '{{ value_json.temperature }}' sensor 7: platform: mqtt state_topic: 'dht22-3/sensor1' name: 'Humidity2' unit_of_measurement: '%' value_template: '{{ value_json.humidity }}'
