Sentinel

Home monitoring system running on a NodeMCU ESP8266 ESP-12F.

The idea behind this project is to have a base system working on a standard microcontroller with communication capabilities, http/https, mqtt...

Hardware

The hardware I currently use is a NodeMCU Lua Amica Module V2 ESP8266 ESP-12FCP2102 micro-controller, a temperature sensor DS18B20 and temperature and pressure sensor BMP180.

Installation

Arduino

Open the Arduino Preferences Ctrl+, and in Additional Boards Manager Urls add the following one:

https://arduino.esp8266.com/stable/package_esp8266com_index.json

Open the Arduino Library Manager Ctrl+Shift+I and install the following packages:

• ArduinoJson
• ArduinoMqttClient
• BMP180_Breakout_Arduino_Library
• WiFiManager

Upload the sketch

Configuration

Connect the device to a power supply.

Connect your phone to the new access point created by the device. It should be something like sentinel-xxx.

Then access the device settings by navigating to http://192.168.4.1 and complete the setup.

The device then will restart and will pair automatically with the server.
