That eight-year-old Android tablet gathering dust in a drawer already has everything a smart home wall panel needs: a touch screen, Wi-Fi, and enough battery to sit trickle-charging for years. The trick is picking the right software layer so it does not fall asleep, does not show ads on the lock screen, and does not stop responding when the internet drops. We tested seven Android apps for turning a spare tablet into a smart home control panel, ranked by how well they hold up over a month of actual daily use.
What to look for
A wall-mounted tablet needs different software than a phone. Five things matter:
- Kiosk mode. The app has to stay in the foreground, blocking the launcher and status bar.
- Screen-off scheduling. Motion-based wake and time-based sleep both keep an OLED alive and prevent burn-in.
- Local-only mode. The dashboard has to work when the router reboots. Anything that phones home is not fit for this job.
- Trust icons that match state. A lock icon in the UI has to reflect the actual lock, not a cached value. Confidence in the panel comes from correctness here.
- Older Android support. Most tablet candidates are on Android 8, 9, or 10. The app has to run there without heroics.

The apps
1. Home Assistant — Best for full local automation with a real dashboard
Home Assistant on an old tablet is a genuinely credible smart home hub display. The companion app has a dedicated tablet dashboard mode, and self-hosted Home Assistant runs everything locally, so a router reboot does not blank the panel. Zone-based automations use the tablet’s location, and motion detection through the front camera can wake the screen only when someone walks up.
Where it falls short: The initial setup takes a Sunday. Once it is running, changes flow through YAML or the UI, and both work.
Pricing:
- Free: Full app and self-hosted server.
- Paid: Optional cloud subscription for remote access.
Platforms: Android, iOS.
Download: Google Play, Aptoide, F-Droid
Bottom line: The dashboard the enthusiast community actually keeps on the wall. Skip if you want zero configuration.
2. Fully Kiosk Browser — Best for locking a tablet into any web dashboard
Fully Kiosk Browser is the workhorse. It locks any web dashboard (Home Assistant, openHAB, HomeSeer) into full-screen kiosk mode with hardware key blocking, motion-based screen wake, and a schedule for night dimming. It also exposes an internal REST API, so the tablet becomes a controllable device inside your automations.
Where it falls short: Requires a purchase to unlock all of the kiosk features. Ads on the free tier are subtle but present.
Pricing:
- Free: Basic kiosk with occasional prompts.
- Paid: One-time modest fee unlocks motion wake, screen scheduling, and the REST API.
Platforms: Android, Amazon Fire.
Download: Google Play, Aptoide
Bottom line: The right answer if you already have a web dashboard and just need a shell.
3. HomeHabit — Best for a polished off-the-shelf dashboard
HomeHabit offers a widget-grid dashboard preconfigured for lights, thermostats, cameras, and calendars. It connects to Home Assistant, SmartThings, Hue, and Nest without extra work, and the layout resizes cleanly on older tablet aspect ratios. Trust icons for locks and alarms match the underlying state within a second, which is what the design system asks for.
Where it falls short: The good bits sit behind a subscription. Free is limited to a handful of devices.
Pricing:
- Free: Up to five devices.
- Paid: Modest monthly subscription for unlimited devices.
Platforms: Android, Fire tablets.
Download: Google Play, Aptoide
Bottom line: The pick if you would rather subscribe than tinker.
4. WallPanel — Best for free open-source kiosks
WallPanel is open-source and free forever. It runs any web dashboard in a locked-down browser and publishes tablet sensors (motion, brightness, temperature) over MQTT, so Home Assistant sees the panel as a device. Setup is more manual than Fully Kiosk, and there is no dedicated support channel, but the community on GitHub keeps it healthy.
Where it falls short: Documentation lags releases. Non-technical users struggle with MQTT setup.
Pricing:
- Free: Everything.
- Paid: None.
Platforms: Android.
Bottom line: The free choice if you are comfortable with MQTT.
5. TinyCam Monitor — Best for a camera-first dashboard
TinyCam Monitor is the app to install when the dashboard is really a camera wall: nursery, garage, front door, back door in one grid. It handles ONVIF, RTSP, and most consumer camera brands without cloud round-trips, and the grid layout scales to older tablet resolutions cleanly.
Where it falls short: No smart-home controls beyond what a camera exposes. This is a viewer, not a hub.
Pricing:
- Free: Up to four cameras.
- Paid: One-time modest upgrade to unlock more feeds and recording.
Platforms: Android, Fire tablets, Android TV.
Download: Google Play, Aptoide
Bottom line: The right dashboard when the primary use is watching cameras.
6. Home Panel — Best for a customisable Home Assistant dashboard
Home Panel is a React-based dashboard originally built for Home Assistant that runs cleanly inside Fully Kiosk on Android. Card layouts drag and drop, and the wall-oriented design keeps hit areas touch-friendly. It is a great option if the default Home Assistant Lovelace dashboard is too dense for a wall.
Where it falls short: Requires Fully Kiosk (or similar) to run properly as a panel. Not a standalone app.
Pricing:
- Free: Everything.
- Paid: None.
Platforms: Web app, wrapped in any Android kiosk.
Download: Web app via Fully Kiosk
Bottom line: The best dashboard UI for Home Assistant walls.
7. Hass.Agent — Best for sensor push back to Home Assistant
Hass.Agent turns the tablet itself into a sensor feed for Home Assistant: motion, ambient light, charging state, battery percentage. Combine it with any of the kiosk apps above and the tablet becomes both display and input. Automations like “turn the tablet on when someone walks up” work without extra hardware.
Where it falls short: Not a dashboard on its own. Meant to sit alongside.
Pricing:
- Free: Everything.
- Paid: None.
Platforms: Android.
Download: Google Play, Aptoide
Bottom line: Install alongside a kiosk app. Not a dashboard by itself, but essential glue.
How to pick the right one
For most people, install Home Assistant, wrap it in Fully Kiosk, and add Hass.Agent for sensor feedback. That combination gives you local-first control, a locked kiosk, and motion wake, all on hardware you already own.
If you are not running Home Assistant, HomeHabit is the closest to plug-and-play. Pay the modest subscription and you get a dashboard configured in an afternoon.
Camera-heavy households should reach for TinyCam Monitor first and layer other panels on top only if needed.
Enthusiasts on a budget can replace Fully Kiosk with WallPanel to keep everything free and open-source, at the cost of a rougher setup.
FAQ
Can any old Android tablet work as a smart home panel?
Yes. Anything running Android 8 or later can host Fully Kiosk or WallPanel. Older devices work if the dashboard is a straightforward web app.
Does the tablet need to be plugged in all the time?
For a wall panel yes. Continuous charging is safe on modern batteries, and screen-off scheduling reduces heat further.
How do I stop the tablet from sleeping?
Fully Kiosk and WallPanel both hold the screen on and block the launcher. Enable USB debugging remote-wake as a backup for hard sleeps.
Do these apps work without internet?
Home Assistant runs entirely on your LAN. Everything else works if the dashboard it points at is local.
What is the best free option?
WallPanel plus Home Assistant. Both are open-source and cost nothing.
