Node-RED

Connect sensors (temperature, motion) using MQTT.

Create a flow to read sensor data.

Use function nodes to define automation rules (e.g., turn on AC when temperature exceeds a threshold).

Control actuators (lights, AC) using HTTP or MQTT.

Visualize data on a dashboard.

Connect to industrial sensors using Modbus or OPC-UA.

Create a flow to ingest sensor data.

Use function nodes to perform data cleaning and transformation.

Store processed data in a database (e.g., InfluxDB).

Visualize data on a Grafana dashboard.

Use HTTP request nodes to call APIs (e.g., weather API, CRM API).

Create a flow to process API responses.

Transform data using function nodes.

Store data in a database or trigger other actions (e.g., send an email).

Monitor API performance using logging nodes.

Deploy Node-RED on an edge device (e.g., Raspberry Pi).

Connect sensors directly to the device.

Create a flow to process data locally.

Send aggregated data to the cloud for further analysis.

Implement local control loops for real-time response.

Connect to data sources (e.g., sensor data, API data).

Create a flow to monitor data for specific conditions.

Use function nodes to define alert thresholds.

Send notifications via email, SMS, or other channels.

Log alert events for auditing and analysis.
