Home Assistant is an open-source home automation platform that allows users to automate various aspects of their homes. Node-RED is a visual tool for wiring the Internet of Things (IoT) devices, making it easy to create automations without extensive coding knowledge. Together, they enable users to control and monitor their smart home devices with ease. To use Home Assistant and Node-RED, users need to install them on a device such as a Raspberry Pi or Windows PC, set up devices, and then link the two platforms. InfluxDB is a time-series database that stores data from IoT devices, allowing for efficient analysis and visualization of sensor data. By installing InfluxDB in conjunction with Home Assistant and Node-RED, users can create powerful automations that store and analyze data from various smart home devices. With these three tools, users can automate their homes to optimize energy consumption, receive notifications, and enhance their overall living experience.
