Seeed Studio reTerminal (Raspberry Pi CM4)

Quick verdict

A tidy, self-contained wall panel for people who would rather not mount a tablet. The CM4 inside is a real computer, so it runs your Home Assistant dashboard locally in a Chromium kiosk - or even Home Assistant Supervised on-device. Expect some DIY: Home Assistant OS won't drive the display directly, so you set up kiosk mode or Supervised yourself. The 5-inch screen is compact, and PoE is available via the optional E10-1 expansion board.

Standout: A Raspberry Pi CM4 5-inch touchscreen that runs your Home Assistant dashboard locally in kiosk mode - a self-contained, offline-capable wall panel.

Compatibility snapshot

Why it stands out

• Self-contained CM4 (quad-core, 4-8GB RAM, 32GB eMMC) - runs a HA dashboard or HA Supervised fully offline
• Rich I/O: Gigabit Ethernet, dual-band WiFi/BT, light sensor, accelerometer, buttons; PoE via the optional E10-1 expansion board
• Industrial 5-inch IPS multi-touch display in a wall-mountable enclosure

Reasons to hesitate

• Premium price versus a cheap wall tablet
• Home Assistant OS won't drive the display - needs kiosk-browser or HA Supervised setup
• 5-inch screen is small for dense dashboards

Best for

• Makers wanting a purpose-built, local HA wall panel
• Installs where a clean fixed touchscreen beats a propped-up tablet

Avoid if

• You want plug-and-play with no Linux/kiosk setup
• You need a large dashboard screen

Privacy and local-control notes

A standalone Linux (Raspberry Pi CM4) device on your LAN. It renders your Home Assistant dashboard locally with no cloud involved.

Home Assistant support: supported · integration path: Runs the Home Assistant dashboard locally (Chromium kiosk) or HA Supervised on-device.
