ESP8266-homie-PIR-DHT

DHT/PIR sensor on NodeMCU using Homie and PlatformIO

Currently uses Homie 3.0.1

Project is built in PlatformIO, see below.

Features

  • Automatically advertises what it does using Homie including units.
    • Motion
    • Temperature
    • Humidity
  • Temp and Humidity readings every 60 seconds (configurable by changing TEMPERATURE_INTERVAL)
  • Motion info as detected (inlcuding OFF after 5 seconds, configurable by changing pause)
  • Easy setup
  • Automatic Discovery in openHAB (>2.5) if MQTT bridge is already configured since uses Homie 3+

Setup

Hardware

DHT22 to GPIO4 (D2 on NodeMCU). If using DHT11, see DHT11 v DHT22 section below.

PIR to GPIO12 (D6 on NodeMCU).

Using with PlatformIO

PlatformIO is an open source ecosystem for IoT development with cross platform build system, library manager and full support for Espressif ESP8266 development. It works on the popular host OS: Mac OS X, Windows, Linux 32/64, Linux ARM (like Raspberry Pi, BeagleBone, CubieBoard).

  1. Install PlatformIO IDE
  2. Download Repo
  3. Add repo PlatformIO
  4. Make any changes you want
  5. Upload to NodeMCU chip

DHT11 v DHT22

This project is currently configured to use a DHT22 sensor. If you are using DHT11, you need to modify main.cpp:

DHT22:
#define DHTTYPE DHT22

DHT11:
#define DHTTYPE DHT11

Upload Firmware directly

If you think my code looks good to go, you can download firmware.bin in “Builds” directory and upload that to your NodeMCU using something like espTool or NodeMCU Flasher. Google these.

Configuration

  1. Upload project to Node chip
  2. Open this URL: https://homieiot.github.io/homie-esp8266/configurators/v2/
  3. Connect to the device’s generated WiFi network, should be called something like “Homie-123456abcdef”.
  4. Follow UI to configure.

Other

Issues

Currently OTA is not enabled.

My code is trash :) I’m a rookie!

Some of this code has been borrowed from others and added to this conglomerate. Will credit them when I get chance.

openHAB

If using with openHAB v2.5 or above, once MQTT is configured, this device will automatically show up in Inbox to add.
