[EXAMPLE] When a '''user1''' publishes an image on social media, then only the '''user2''' subscribed to '''user1''' can view/receive the image. Here, the '''user1''' is the '''PUBLISHER''', '''user2''' is the '''SUBSCRIBER''', and the '''user1's account''' is the '''BROKER'''.* According to the above analogy, the image that is published is the data, that was '''transferred from user1 to user2''' 📤. And that is the exact scenario in an MQTT Pub/Sub model. * We have a more secure layer 🔒 to make sure the data is shared t'''hrough a specific path, we call th'''at 'topic', When use'''r1''' publishes data on topic, the subscriber automatically receives if already connected to the broker. Hence, t'''he''' LOW latency.connected to the broker. Hence, t'''he''' LOW latency.)
Examples:
Turn on the lights when the sun sets.
Receive an alert if you accidentally leave the garage door open.'''Extendable with Add-Ons''': Home Assistant isn’t limited to its core functionality. You can easily install additional applications (add-ons) to enhance your setup.
Examples:
Run AdGuard for DNS-based ad blocking.
Use NodeRed for third-party automation.
Turn Home Assistant into a Spotify Connect target.'''Local Data Privacy''': Unlike cloud-based solutions, Home Assistant keeps your data local. It communicates directly with your devices without relying on external servers. Your privacy is preserved, and no data is stored in the cloud. '''Companion Mobile Apps''': Control your devices and receive notifications using the official Home Assistant apps. These apps also enable presence detection, allowing you to trigger automation based on your location. Rest assured, your data is sent directly to your home, with no third-party access. '''Installation Options:''' '''Home Assistant OS''': A ready-to-use image for devices like Raspberry Pi, Odroid, or Intel NUC. '''Home Assistant Supervised''': Install Home Assistant on a generic Linux system using Docker. '''Home Assistant Container''': Run Home Assistant in a Docker container. '''Home Assistant Core''': For advanced users who prefer manual installation on Python environments. By setting it up in a virtual machine, you can experiment with Home Assistant without affecting your primary Windows environment. === Prerequisites: === * '''Windows 11''': Ensure you’re running Windows 11 on your host machine. * '''VirtualBox''': Download and install VirtualBox if you haven’t already.re you’re running Windows 11 on your host machine. * '''VirtualBox''': Download and install VirtualBox if you haven’t already.)
