# node-red-setup

This is the node red setup of my personal IoT environment at home.

## Smart Socket Control

One flow controls the smart sockets. In this case TECKIN sockets are used. They are integrated using [node-red-contibr-tuya-smart](https://github.com/hgross/node-red-contrib-tuya-smart).

### Features

- On/Off buttons are controlled by the socket as they can be controlled from outside of the application

- Status message, weather the sockets are online or not using flow variables

- Power Off-Safety: It is not possible to deactivate a socket if there is to much current flowing

- Display of the values in a gauge (real time) and a chart (5 minute aggregation)

## Sensor control using MQTT

The second flow controls MQTT devices. MQTT is handled by a [Mosca MQTT Broker](https://flows.nodered.org/node/node-red-contrib-mqtt-broker).

### Features

- Read temperature and humidity

- Read gas concentration (currently not fully implemented)

- Display of the values in a gauge (real time) and a chart (5 minute aggregation)

- Controlling a LED (On/Off)

- Controlling a Display

## UI

## Sensor/Actuator Setup

The Sensor/Actuator system uses a Wemos with an ESP8266 microcontroller.  

For temperature and humidity, a DHT22 sensor is used, reading through digital input.  

For the natural gas concentration, a MQ-5 sensor is used, reading through analog input.  

The display is a 128x64 i2c SSD1306 display.
