Transform Your iPhone into the Ultimate Home Assistant Control Panel: Fast UX Wins

If youโ€™re reading esp32.co.uk, you probably already have Home Assistant stuffed with ESPHome sensors, smart relays, and automations that look like a small PhD thesis.

But none of that matters if turning a light on takes 10โ€“15 seconds of app-fumbling.

The โ€œfast UX winโ€ is simple: pull your most common actions out of the Home Assistant UI and put them directly onto iOS (Control Center, Lock Screen, widgets, buttons). Home Assistant stays the brain โ€” your iPhone becomes the remote thatโ€™s actually fast.

Rule of thumb: pick 5โ€“8 actions max. If you add 30 buttons, youโ€™ve reinvented a slow dashboard.


1) iOS 18 Control Center + Lock Screen (no app-hunting)

With iOS 18 support in the iOS Companion App, you can add native Control Center controls for Home Assistant, including:

  • Assist
  • Toggle light
  • Run script
  • Activate scene
  • Open page

This is the fastest โ€œmuscle memoryโ€ path: swipe, tap, done. And if youโ€™ve got an iPhone 15 Pro / 16 series, these controls can also be mapped to the Action Button, cutting steps even further.

Home Assistant also supports starting Assist from multiple iPhone entry points (including Control Center and Lock Screen).

What to put here (best ROI):

  • Gate / garage
  • Alarm arm/disarm
  • โ€œAll lights offโ€
  • โ€œGoodnightโ€
  • Assist

2) Home Screen widgets that actually do things

Widgets are where Home Assistant starts feeling โ€œnativeโ€.

Best options:

  • Custom Widgets (beta): the most flexible option โ€” you can choose entities, icon + colors, background, and what happens โ€œon tapโ€ (including requiring confirmation for dangerous stuff).
  • Details / Gauge widgets (advanced): show key sensor data (e.g., temp/humidity/air quality) using templating (admin required for templating).
  • Actions widget: a clean list of your curated โ€œdo this nowโ€ commands, also used by Apple Watch.

Fast UX move: create two widget zones:

  • Day: gate, garage, alarm, climate boost
  • Night: goodnight, lights off, arm night

3) Hardware shortcuts: Action Button + Back Tap (stupid-fast)

Touchscreens are fine. Physical triggers are better.

Home Assistant explicitly supports launching Assist via:

  • Back Tap
  • Action Button
  • Control Center
  • Lock Screen

So you can do things like:

  • Double back-tap โ†’ Assist โ†’ โ€œTurn on lounge lightsโ€
  • Action Button โ†’ Assist (or a specific script/scene)

This is the closest thing to โ€œpush-to-talkโ€ for your house.


4) Siri Shortcuts (when you want iOS-native voice + automation glue)

Shortcuts are still useful for:

  • Running HA actions from Siri (โ€œHey Siri, Movie Modeโ€)
  • Chaining iOS stuff + HA stuff (e.g., set phone volume + run HA scene)

The Companion App supports Siri Shortcuts and lets you call HA services (plus other actions) directly from the Shortcuts app.

Pro tip: keep Siri phrases short and unambiguous. If Siri mishears it, your smart home becomes a slot machine.


5) NFC tags: zero taps, โ€œESP32-maker approvedโ€

Buy a pack of NFC stickers (NTAG213/215/216), and place them where actions make sense:

  • Bedside table โ†’ โ€œGoodnightโ€
  • Near front door โ†’ โ€œAwayโ€
  • By garage door โ†’ โ€œOpen/Close garageโ€
  • On fusebox / network rack โ†’ โ€œMaintenance modeโ€

Home Assistant iOS supports NFC tags via a Home Assistant URL format; on iOS you typically get a notification which, when tapped, launches the app and fires the tag_scanned event.
Both Android and iOS apps can read and write tags, and some tags may be read-only / limited-write.

This is one of the few smart home interactions that feels genuinely โ€œinstantโ€ and natural.


6) Speed up the app for the times you do open it

Even with OS-level controls, youโ€™ll open the HA app sometimes. Donโ€™t let it be slow.

Two high-impact tweaks:

  • Set an Internal URL in the Companion App so youโ€™re not routing oddly when youโ€™re at home. (This is literally in the Companion settings path.)
  • Create a mobile-first landing dashboard: buttons first, no heavy graphs/cameras on the first view.

A practical โ€œstarter packโ€ (copy this)

If you want maximum speed with minimum tinkering, start with these 5 actions everywhere (Control Center + widgets):

  1. Gate / garage
  2. Arm Night
  3. Disarm (with confirmation)
  4. All lights off
  5. Goodnight scene

Then add one โ€œpower featureโ€:

  • Back Tap โ†’ Assist or
  • NFC bedside tag โ†’ Goodnight

Thatโ€™s it. Anything beyond that earns its place.
