Old tablets pile up. A first-generation Fire tablet, a five-year-old Galaxy Tab, a Kindle Fire someone gave up on, a Nexus 7 that still boots. Most are useless as personal devices in 2026 but excellent as a permanent wall display in a hallway or kitchen. The XDA piece on turning a discontinued Kindle into a smart home display is part of a much larger pattern: pick a tablet, mount it, point it at a Home Assistant dashboard, and forget it exists. The piece that actually decides whether it works is the software running on the tablet. These are the seven apps to turn an old tablet into a smart home wall display in 2026.
What to look for in a wall-display app
The job is narrower than a regular browser. The right app has most of these:
- True kiosk mode that hides the navigation bar and locks the user inside one URL.
- Motion-activated wake or a proximity sensor hook, so the screen turns on when someone walks up.
- A scheduled brightness curve, so the display dims overnight without manual intervention.
- MQTT or Home Assistant integration, so the tablet itself becomes a sensor the dashboard can react to.
- Survives reboots and Android updates. The tablet should come back to the dashboard automatically.
- Battery management that handles “always plugged in” without cooking the battery.
- Cost. Most of these have free tiers that cover a household; the paid tiers buy MQTT and OTA features.
The apps
1. Fully Kiosk Browser — Best overall
Fully Kiosk Browser is the default answer for a reason. It locks the tablet into one URL, supports motion detection through the front camera, exposes a REST API and MQTT so Home Assistant can flip the screen, control brightness, and read the tablet’s battery as a sensor, and survives Android updates and reboots cleanly. The free tier covers casual use; the Plus licence unlocks MQTT, full Java API, and removes the watermark.
Pricing:
- Free: full kiosk mode, motion wake, basic scripting
- Paid: Plus licence around €7.90 per device, one-time
Platforms: Android (phone, tablet, Fire OS).
Download: Aptoide · Google Play
Bottom line: Pick Fully Kiosk Browser unless you have a reason not to. Most household wall-display setups end here.
2. Home Assistant Companion — Best for a Home Assistant-first house
Home Assistant Companion is the official Nabu Casa app. It is not a kiosk browser by default, but recent versions added a fullscreen dashboard mode and the integration is tighter than any third-party app can manage. Sensors (battery, location, network, proximity) come through automatically and become Home Assistant entities.
Pricing:
- Free: full app, all sensors and dashboards
- Paid: Nabu Casa subscription (about $6.50/month) for remote access
Platforms: Android and iOS.
Download: Aptoide · Google Play
Bottom line: Pair Companion with a launcher in kiosk mode (or with Fully Kiosk as a wrapper) for the deepest Home Assistant integration.
3. WallPanel — Best free open-source option
WallPanel is an Apache-licensed kiosk app that targets exactly this use case. It locks the tablet into a single URL, has MQTT control built in, supports motion detection via the camera, and ships face-detection that wakes the screen when a person walks up. Source is on GitHub.
Pricing:
- Free: full app
- Paid: none
Platforms: Android.
Download: Aptoide · Google Play
Bottom line: Pick WallPanel when “free, open-source, MQTT” is the requirement and a slightly less polished UI is fine.
4. HomeHabit — Best for tablets that aren’t on Home Assistant
HomeHabit is a dashboard-first app. It speaks Home Assistant, MQTT, Hubitat, SmartThings, and Tasmota natively, and the dashboards are designed for wall mounting from the start. The interface is closer to a SmartThings panel than to Home Assistant’s Lovelace.
Pricing:
- Free: full dashboard for one device
- Paid: about $5 one-time unlocks more devices and themes
Platforms: Android.
Download: Aptoide · Google Play
Bottom line: Pick HomeHabit when the household runs SmartThings or Hubitat instead of Home Assistant.
5. Kiosk Browser Lockdown — Best for managed deployments
Kiosk Browser Lockdown is a commercial kiosk browser aimed at small businesses but useful at home. It supports remote management of multiple devices, scheduled URL changes, and a true single-app mode that locks down system settings.
Pricing:
- Free: basic kiosk mode
- Paid: from about $4/month per device for managed features
Platforms: Android.
Download: Aptoide · Google Play
Bottom line: Pick Kiosk Browser Lockdown when “I run six wall displays across two homes” is the actual scenario.
6. Hass.io Kiosk — Best for an explicit Home Assistant pairing
Hass.io Kiosk is a thin Android wrapper around a Home Assistant dashboard. No motion sensing, no MQTT bridge — just a fast, reliable shell that opens a Lovelace dashboard fullscreen, holds it there, and reconnects if the tablet sleeps.
Pricing:
- Free: full app
- Paid: none
Platforms: Android.
Download: Aptoide · Google Play
Bottom line: Pick Hass.io Kiosk when the only requirement is “open one Home Assistant URL and stay there”.
7. FreeKiosk — Best Apache-licensed alternative
FreeKiosk is an actively-developed open-source kiosk app pitched as a Fully Kiosk replacement. It supports lockdown PIN protection, single-URL mode, scheduled wake/sleep, and a no-watermark experience without a paid licence.
Pricing:
- Free: full app
- Paid: none
Platforms: Android 8.0+.
Download: Aptoide · Google Play
Bottom line: Pick FreeKiosk when the paid Fully Kiosk licence feels excessive for a single household tablet.
How to pick the right one
If you want the most-supported, set-and-forget option: Fully Kiosk Browser.
If you want fully free, open-source, and the most Home Assistant features: WallPanel or FreeKiosk.
If your hub is SmartThings or Hubitat, not Home Assistant: HomeHabit.
If you run six tablets and want central management: Kiosk Browser Lockdown.
If you want the deepest Home Assistant integration and don’t care about kiosk lockdown: Home Assistant Companion.
FAQ
Can I use a discontinued Kindle Fire as a smart home wall display?
Yes. Most Fire tablets sideload Fully Kiosk Browser or WallPanel without issue. Disable Amazon’s Special Offers screen, sideload Google’s Files app and the kiosk app of choice, and mount.
Will leaving the tablet plugged in damage the battery?
Older tablets will degrade their batteries over time on permanent power. Use a USB cable with battery protection circuitry, or open the case and connect power directly to bypass the battery — popular for permanent installs.
Do I need root or a custom ROM?
No. All seven apps run as standard Android apps. Some advanced features (single-app pinning, full device administration) work better with device-owner mode, which requires ADB but not root.
Can I use an iPad instead of an Android tablet?
Yes. iPads can run Home Assistant Companion or kiosked Safari via Guided Access. Most dedicated kiosk apps in this list are Android-only.
Which app gives me wake-on-motion?
Fully Kiosk Browser (camera-based motion), WallPanel (camera-based with face detection), and FreeKiosk (camera-based) all support wake-on-motion. Home Assistant Companion can do it via the proximity sensor where the tablet has one.
What dashboard do I point the tablet at?
Home Assistant’s Lovelace is the most common, especially with the Mushroom or Bubble Card themes built for kiosk-sized layouts. SmartThings dashboards, Hubitat dashboards, and Node-RED dashboards also work.
