Hardware

• Raspberry Pi 5 in a passive Flirc case, booting from USB
• Samsung DB22D – 22" Smart Signage LED display, mounted horizontally
• Connected via HDMI (video) and USB (touch)
• IKEA SYMFONISK bookshelf speaker (Sonos) mounted below the screen, sitting on the SYMFONISK shelf with built-in wireless phone charging – so the mirror doubles as a charging station
• S3KM1110 mmWave radar sensor for presence detection (much more reliable than PIR – it detects you even when you stand still)

Software overview

• MagicMirror² on Raspberry Pi OS Bookworm
• 19 pages, navigated by swipe gestures (MMM-Touch + MMM-pages + MMM-page-indicator with custom FontAwesome icons per page)
• MMM-ModuleScheduler switches between day and night layout automatically
• MMM-Remote-Control for administration and as an API for my presence script

The pages

Family calendar

MMM-CalendarExt3 in week view, merging iCloud family calendars, school holidays, both kids’ football clubs’ match schedules (auto-imported from the association’s ICS feeds), Juventus fixtures and the F1 calendar – color-coded per source.

School timetables (3 pages)

One page per child, rendered with MMM-CalendarExt3Journal as a proper weekly timetable grid. The data comes straight from the schools’ ICS exports, so it updates itself – no manual maintenance. The kids check their own page in the morning.

Shopping list with recipe integration

MMM-Bring shows our Bring! lists with full touch support – tap to add items (on-screen keyboard), tap to check them off. We use multiple lists; one of them is fed by Tandoor Recipes (self-hosted on a Synology NAS): when I add a recipe’s ingredients to the shopping list in Tandoor, they appear on the mirror. Meal plan and recipe of the day come from a small self-written MMM-Tandoor module.

News ticker with AI comic generation

This is my favorite gimmick. A self-written module (MMM-NewsComicFeed) shows rotating headlines from Swiss news sources at the top, plus Juventus/F1 feeds at the bottom. Tapping a headline sends it through the Claude API, which writes a comic scenario in one of 15 styles; an image model renders it, and the result is posted to Mastodon and shown on the mirror. Instant satire from the morning news.

Claude assistant page

A self-written chat module with an inline DE/CH keyboard, Markdown rendering and optional web search – the family can ask anything directly on the mirror. The comic generation can be triggered from here as well.

More pages

Weather (OpenWeather one-call), Pi-hole statistics, live football scores, F1 dashboard, a math clock (AlbertClock), a German word clock, YouTube playlists, Sonos control, Mastodon timeline, Home Assistant sensors (dishwasher status and even the car’s fuel level on the main page), and a thermal dashboard (see below).

Presence detection & power management

A Python script reads the mmWave sensor via GPIO and controls the display: DPMS + HDMI-CEC off after 1h without presence during the day, 15 min at night. When the screen turns off, the script also calls the MMM-Remote-Control API to switch the mirror to an empty hidden page.

Why that last step matters: I rewrote MMM-Webview so that embedded web pages unload their Electron renderer process when hidden and reload when shown. Combined with the presence script, all heavy web content dies as soon as nobody is around – a big win for RAM, CPU and temperature on a passively cooled Pi.

Heat management (passive case, no fan)

With several Electron webviews the Pi used to sit at 55–75 °C. To understand what was going on I built MMM-ThermalWatch: current temperature/clock/load, a 24h/7-day max-temperature bar chart (touch to switch views, tap a bar for details), throttle-flag decoding, and a peak log that captures which processes were actually busy whenever a temperature threshold is crossed – measured as instantaneous CPU from /proc snapshots, with proper labels for Electron child processes.

The verdict: the peaks were exactly the parallel webview renderers. Since the suspend/resume rewrite and the presence integration, evenings run noticeably cooler – all of it without a fan.
