Introduction to openHAB 3.0

Install openHAB 3.0 on a Raspberry Pi 4 with openHABian, flash the 32-bit image via Balena Etcher, and manage via SSH and the openHABian configuration tool.

Configure openHAB 3.0 from the dashboard by creating the admin account, performing initial configuration, and adjusting regional, network, and security options, then manage things, items, and persistence.

Explore openHAB 3.0 UI overview, covering the Main UI, semantic modelling, pages, the Basic UI, and HABPanel, and discover which UI to use for different devices and use cases.

Explore the openHAB 3.0 main UI dashboard and configuration, including addons, bindings, Things, and Channels, and compare defining components via the Main UI, text files, or the console.

Learn to define items in the main UI, create rules and triggers, and configure persistence and transformations in openHAB 3.0 for home automation.

Explore openHAB 3.0 setup on a Raspberry Pi from a PC, installing VS Code and the openHAB extension, and editing openHAB text files via mapped Pi folders.

Explore ui-driven configuration in openHAB 3.0 and file-based configuration workflows, including adding things, channels, items, pages, and rules with astro binding.

Learn how to set up openHAB file-based configuration by installing bindings textually, defining things with .things files, and creating items linked to binding channels via the REST API.

Explore file-based openHAB 3.0 setup using VS Code to define Things and Items, leverage syntax checking and group-based semantic modeling, link channels, and manage items via the main UI.

Create sitemaps in openHAB 3.0 by defining sitemap elements and their types, applying map transformations, and using icons in the basic UI.

Define persistence strategies for openHAB 3.0, configure group and item persistence with rrd4j, and create a .persist file to visualize charts in the UI.

Define openHAB 3.0 rules with textual configuration, using when-then logic and multiple triggers, and implement scenes like morning and movie while logging via the openHAB log viewer for debugging.

Explore what scripts are, how they differ from rules, and how to implement script blocks using Xtend in openHAB 3.0, with languages like Blockly, ECMAScript, Rule DSL, and Groovy.

Design a capstone home security and thermostat system with openHAB 3.0, using MQTT and ESP32 sensors, Raspberry Pi 4 as central hub, and actuators like relay and buzzer.

Learn how to set up MQTT in openHAB: install Mosquitto, configure the MQTT broker thing, and connect devices using the MQTT binding for your capstone project.

Configure the MQTT broker and bridge, create a generic MQTT thing linked to the broker, add a switch channel with state and command topics, and verify the connection with MQTTLens.

Learn to interface sensors and actuators with ESP32s, code in the Arduino IDE, and connect them to openHAB via MQTT for a unified main UI dashboard and rules.

Design the main UI dashboard in openHAB 3.0, display motion, temperature, and humidity, and implement rules to control the buzzer and thermostat system.

Explore project testing and upgrades for openHAB 3.0, including data persistence for visualization with charts and Telegram binding for mobile alerts via PIR and thermostat rules.

Explore advanced openHAB 3.0 concepts, including main UI, file-based and textual configuration, and bindings like astro and mqttitude, plus project ideas, triggers, and security sensors.

Recap the beginner-friendly openHAB 3.0 course, covering UI-driven and file-based configurations. Explore core components such as bindings, things, channels, items, rules, scripts, and sitemaps, and the main UI focus.
