Intro to Home Assistant

Smart Homes Done the Right Way · Speaker Cue Outline

Format: Talk with hardware props, no live system on screen · Audience: complete beginners · Venue: Dallas Makerspace · Duration: ~95 min of content in a 2-hour slot, 5-min stretch break

Block 1: The Hook: Home Assistant Alongside Apple, Google, and Alexa (5 min)

  • Cold open, no intro, no slides
  • Hands up: Echo? Google speaker? HomeKit? More than one?
  • "Unfortunately, your home still isn't very smart."
  • The pain: an app per room, works with one assistant but not the other, features pulled in an update, dead when the internet dies
  • Nobody throws anything out tonight: all three are easy to start, each only talks to its own stuff
  • The turn: HA goes underneath; devices connect to HA, HA hands them back to Alexa, Google, or Apple, keep the speaker you already use
  • What that buys: one place everything meets, automations across brands, keeps working offline
  • Proof: mailbox opens → camera snapshot → phone notification → AOL "You've got mail" on every speaker → "Nobody sold me that. I built it in an afternoon. Let me show you how we got here."
  • Gear on the table all night, picked up as it comes up

Giveaway Announcement (~1 min)

  • "One of you is taking something home tonight. I'm not telling you what it is until the drawing."
  • Must be present to win. The drawing happens at the end of the night.
  • Winner drawn from a name wheel; get first names as people arrive
  • Milk the mystery: mention the box exists, don't open it, move on.
  • The class URL (classes.smarthomesellout.com): whiteboard before doors open, say it twice. "Everything tonight is on this site. The handout has every link and gear pick, so follow along on your phone if you want. Nobody needs to take notes."

Block 2: What is Home Assistant? (8 min)

  • Brief history: started 2013, Paulus Schoutsen
  • The core idea: HA is the middleman. One app in the middle, every protocol (Zigbee, Z-Wave, Wi-Fi, Bluetooth) connected to it, instead of ten vendor apps that don't talk to each other.
  • Open Home Foundation: vendor-neutral, privacy-first, open source
  • Nabu Casa: commercial arm, funds development, HA Cloud (remote access, Alexa/Google, voice); hold up the hardware
  • Apollo Automation: "I work here. We make ESPHome-based sensors, and we're one of the companies Nabu Casa is trusting to help monetize and grow ESPHome commercially."
  • The ecosystem, three tiers (openhomefoundation.org/projects):
    • Owned outright: Home Assistant, ESPHome, Music Assistant
    • Collabs (partners, not owned): Zigbee2MQTT, WLED (the panel in the corner), OpenDisplay
    • Standards, drivers, libraries (250+): Z-Wave JS, HACS, zigpy, Improv Wi-Fi, ESP Web Tools, Piper
  • Philosophy: local-first, no vendor lock-in, your data stays yours
  • aio-libs closer: aiohttp, yarl, multidict and friends, how HA talks to every device at once without choking; volunteers keep them alive → donate link in handout

Block 3: How to Run It (6 min)

  • Why HAOS: easiest, best supported, full app ecosystem
  • Hardware:
    • HA Green: official plug-and-play
    • Raspberry Pi: popular, well documented
    • A used mini PC or an old laptop: needs 6th-gen Intel or newer; a laptop works even with a dead/no screen (headless); mini PC e.g. Lenovo M910q or similar
    • Heads up: mini PCs used to be a lot cheaper before the AI boom drove demand up
    • N100/N150 mini PCs: new off Amazon, great value + headroom
  • Advanced options: running a VM on a server, or a Docker container

Block 4: Core Concepts + Good Integrations (13 min)

  • Integrations: how HA connects to devices & services
  • Add-ons / Apps: extend HA (Mosquitto, ESPHome), "app" terminology
  • Cloud vs Local: works without internet, privacy, speed, no subscription
  • Integrations worth knowing (the "it does that?" list):
    • UniFi / UniFi Protect: network presence + cameras
    • WLED: addressable LEDs; runs on certain smart bulbs or LED controllers; the panel in the corner is running it, HA can drive it
    • Z-Wave: bring your Z-Wave gear into HA
    • ESPHome: your own DIY sensors/devices into HA
    • Alarmo: full alarm system, free
    • BTHome: local Bluetooth sensors, no cloud
    • Frigate: local AI camera / object detection
    • HomeKit Device: pair Wi-Fi devices into HA via the HomeKit protocol
    • HomeKit Bridge: push HA devices out to Apple Home for Siri control; local and free (Alexa/Google need HA Cloud); callback to the opening
    • Plex: "I use it to play media on my TVs as part of morning/night routines"
    • Team Tracker: the fun one: flash LEDs or fire an effect when your team scores a touchdown; build DIY scoreboards with ESPHome or WLED firmware on a HUB75 LED matrix

Block 5: Protocols (15 min)

  • Z-Wave: mesh, licensed spectrum, very reliable, needs a controller
    • Best controller by far: Home Assistant Connect ZWA-2 (not a generic Zooz stick); hold it up
  • Zigbee: mesh, open standard, huge ecosystem, needs a coordinator
    • ZHA (built-in) vs Zigbee2MQTT (independent, broadest device support)
    • Your story: Hue bulbs paired straight to Z2M, no bridge, no account, no cloud
    • Gear: Hue bulbs, Aqara (T1M, door/window sensors, Magic Cube), Third Reality
    • New IKEA stuff: newer Thread-era devices can still pair over Zigbee via Z2M (verify models)
    • Recommended coordinator: Home Assistant Connect ZBT-2, next to it on the table
  • Wi-Fi / Ethernet: direct IP, no hub
  • Bluetooth / BLE: short range, passive sensors, proxies
  • Thread & Matter: honest but gentle. Promising, but still working through firmware/reliability growing pains that Zigbee and Z-Wave sorted out years ago. Beginners can wait.

Bulbs vs Switches vs Relays (~5 min)

  • Frame it as its own moment: this is the buying decision beginners get wrong most often
  • Smart bulbs: per-bulb color + dimming; downside: flip the wall switch and the bulb loses power and vanishes from HA
  • Smart switches: replace the wall switch, keep normal bulbs, physical switch still works (spouse-friendly); no per-bulb color
  • In-wall relays (Zooz, Shelly): hide behind your existing switch; keep the fixture and wall control, just add brains. Best for retrofits and dumb fixtures
  • Each comes in Zigbee / Z-Wave / Wi-Fi (Zooz for Z-Wave, Shelly for Wi-Fi; Shelly is the popular pick)
  • Rule of thumb: switches & relays keep the wall working for family/guests; bulbs are for color everywhere

Q&A Stop 1 (3 min)

Short questions on the spot, longer ones parked to the end.

Block 6: HA Walkthrough (10 min)

  • Skip onboarding: describe a working system, that's what sells it
  • Dashboard deep-dive: sections, cards, the view they'd actually use at home (skip the menu tour)
  • HACS (Home Assistant Community Store): custom cards, themes, community integrations beyond what's built in
    • Theme worth naming: Catppuccin Macchiato
    • Caveat: HACS is foundation-governed, what you install through it is not; install sparingly
  • Companion app (iOS/Android): install, sign in, presence/device tracking, push notifications
  • Adding integrations: a couple of clicks in Settings, most want an account or API key; point at the list on the site
  • Create a simple automation: turn a light on/off with a Zigbee button, with the button in your hand
  • The App store: Mosquitto, ESPHome, File editor

Break (5 min)

Enter the names into the wheel.

Block 7: Automations & Scripts: The Payoff (8 min)

  • Automations = "when X happens, do Y": they run themselves
  • Your real examples:
    • Mailbox alert, the one from the opening: mailbox opens → camera snapshot → phone notification with the image + "You've got mail" → also pops on the desktop PC and the TVs (if online) → plays the old AOL "You've Got Mail" clip on the HomePods around the house; one trigger, four actions, pieces on the table
    • Leaving home (device tracker): I leave → lock doors + arm alarm → snapshot of the room → lights brightness/color off then back on → sleep the PC
  • Scripts = a saved routine you trigger on demand (vs automations that fire themselves)
    • Your wake-up routine and goodnight/sleep routine scripts
    • Can be fired by a button, voice, the dashboard, or called by an automation
  • Takeaway: automations react, scripts are reusable routines, and they combine

Block 8: ESPHome & Building Your Own (4 min)

  • What it is: turns cheap ESP32 chips into HA devices using YAML
  • Part of the ecosystem, under the Open Home Foundation like HA itself
  • Apollo Automation builds on it (your gear)
  • ESPHome Starter Kit: upcoming on-ramp into ESPHome → "I've got a beta version here to show you" (pass it around)
  • Full hands-on build is its own future class, tease it

ESPHome reference notes (keep for the future class, not spoken here):

  • How it integrates with HA, what YAML is, what a "component" is
  • ESP32 variants: WROOM32 (original, solid general purpose) / C3 (RISC-V, single core, budget, simple sensors) / C6 (native Thread + Zigbee, Wi-Fi 6) / S3 (dual core, more GPIO, PSRAM, heavier workloads)
  • PSRAM: what it is, when you need it (WLED, driving TFT/e-ink displays)
  • Flash: 4MB vs 8MB and OTA implications
  • Why not ESP8266: slow, low flash, missing critical peripherals (I2C, LEDC, multiple UARTs); ESP32 is cheap enough there's no reason to deploy 8266 today
  • Why the ESPHome add-on in HAOS makes onboarding/flashing easy
  • Future-class build: ESP32 WROOM32 + DHT22 + 5-pixel WS2812B strip: YAML walkthrough, flash, watch it appear in HA, dashboard + light effects

Block 9: More Ways to Interact: Voice & Wall Displays (4 min)

  • HA Voice Preview Edition: local voice assistant hardware; pass it around here
    • Honest caveat: replacing/mimicking Alexa or Google takes real manual setup today, not plug-and-play yet
  • Wall tablets + Fully Kiosk: cheap tablet as a wall-mounted dashboard
    • Fully Kiosk handles screen on/off (motion wake) + locked-down kiosk mode

Block 10: Claude Code + HA MCP (6 min): the finale

  • What it is: an AI agent that talks directly to your HA through the MCP
  • Configure devices, build dashboards, write automations by asking
  • Before and after: what you typed, what came back, how long it took; result open on the laptop, send it down the front row
  • Why it's a big deal for beginners: lowers the wall between "I have an idea" and "it's running"

Block 11: Where to Go Next (3 min)

  • HA Docs: the integration library is your best friend
  • ESPHome.io: component reference (and tease the ESPHome class)
  • Community: ESPHome Discord, r/homeassistant, r/esphome
  • Quality YouTube: digiblur and other rigorous folks
  • Influencer warning: sponsorships/affiliate links, cross-reference the community
  • Content decay warning: HA moves fast, check dates, go straight to official docs

The Giveaway Drawing (~2 min)

  • Reveal the prize now, then draw the winner.
  • Name wheel (wheelofnames.com) on the laptop: names entered during the break, hold it up, spin, read the winner out loud
  • Don't write the actual item in this outline. The outline is public and the mystery is the fun part.
  • If the prize happens to be something with a voice, letting it announce its own winner is a great reveal (cut the gag if running long).

Q&A Stop 2 (8 min)

Running time: ~94 min content + 5 break ≈ 100 min, scheduled in a 2-hour slot. Q&A, the drawing, and overruns live in the buffer.
