A wall dashboard is two systems with one link between them. The tablet shows a Home Assistant dashboard, and Home Assistant talks back to the tablet to wake the screen, dim it and watch its battery. Most buying advice stops at screen size. The link is what decides whether the panel still works a year from now: which kiosk app the tablet can run, how it gets power, and whether its battery survives being plugged in 24/7.
So this guide to the best tablet for a Home Assistant dashboard picks hardware by that link first. Prices are from Amazon US on October 19, 2026, and we built and tested the battery charge automation further down on Home Assistant 2026.10.2 the same day. We didn’t mount any of these tablets on our own wall, so the hardware notes come from vendor documentation and the owners we quote.
| Pick | Best for | Price | Kiosk path | Charge limit |
|---|---|---|---|---|
| Samsung Galaxy Tab A11+ | Most Android homes | $299.99 | Companion launcher or Fully Kiosk | Check Settings > Battery |
| Apple iPad (A16) | Apple homes, no sideloading | $399.99 | Companion Kiosk mode | Yes, 80% |
| Amazon Fire HD 10 | Lowest cost | $72.99 | Appstore app or sideloaded Fully | None found |
| Lenovo Tab Plus Gen 2 | Big screen | $269.99 | Companion launcher or Fully Kiosk | Unconfirmed |
| RAYPODO 10.1 PoE panel | One cable, no battery | $329.99 | Android app of your choice | No battery |
| SONOFF NSPanel Pro 120 | Replacing a wall switch | $129.90 | HA app from built-in F-Droid | No battery |
Of those columns, the kiosk path matters most, because it decides how much control Home Assistant has over the screen. The next section explains why.
Pick the kiosk path before the tablet
On the Home Assistant side, the link is the same for every tablet: a dashboard, ideally under a dedicated user for each panel. What changes is the app on the tablet and how much of the device it lets Home Assistant control. There are three paths, and they do not overlap much:
- Android Companion app as the launcher: the Home app option makes the tablet boot straight into Home Assistant, and a Keep screen on toggle stops it from sleeping. It is free, and Home Assistant can wake the screen and set its brightness through notification commands, but it cannot switch the screen off or use the camera.
- iOS Companion app in Kiosk mode: Kiosk mode hides the sidebar and status bar, keeps the screen awake, runs a clock, dim or blank screensaver and can wake on front-camera motion. Home Assistant can show or hide the screensaver and set brightness while the app is in the foreground. It’s iOS-only, and Apple’s Guided Access locks the iPad to the app.
- Fully Kiosk Browser on Android: the PLUS licence is 10.99 USD per device, one-time, and it unlocks the Fully Kiosk integration. Home Assistant then gets a true screen on and off, brightness, a switch for Fully’s own camera motion detection, and a battery level sensor.
We’d pick Fully Kiosk on any Android panel that should go fully dark at night and wake when someone walks up. It’s the only path here with a real screen power-off from Home Assistant and a locked-down Android device. Pair it with a presence sensor and the panel can wake before anyone touches it. The native Companion modes are simpler and need nothing extra, and on an iPad Kiosk mode covers most of the same ground with a blank screensaver instead of a powered-off screen.
One thing we’d avoid is building the panel around the community kiosk-mode plugin from HACS. Its latest release only works on Home Assistant 2026.10.1 or newer, and the maintainer warns users on older versions not to update. That’s the ninth major release since May 2025, most of them flagged as breaking, so a core update can bring the header and sidebar back until you update the plugin too. The Companion app modes don’t depend on it.
Choose the tablet for the wall
Each pick below names the kiosk path it supports, how it takes power and how it handles a battery that never unplugs, because those three things decide how long it lasts on a wall. Two names are missing on purpose: Google discontinued the Pixel Tablet in September 2026, and Samsung’s Tab A9 series is now sold on Amazon only by third parties.
Samsung Galaxy Tab A11+: best Android wall tablet
For most walls, we’d pick the Tab A11+. It runs Android 16 with Google Play, so the full Companion app and Fully Kiosk install the normal way, and SamMobile reports a promise of seven Android upgrades, the longest in this group. The 11-inch 1920×1200 screen runs at 90 Hz, and the 6 GB model is enough for a busy dashboard.
- Battery: Samsung’s Battery protection setting has a Maximum mode that stops charging at 80%. Samsung documents it for phones, so confirm it under Settings > Battery on the tablet before you rely on it.
- Mounting: the Mount-It flush wall mount at $69.99 lists the Tab A11+ by name and routes the charging cable through the back.
- Price: it launched at $249.99 in the US and sells for $299.99 at Amazon.com now, so it’s worth watching for a sale.
It is the wrong pick for a single-cable PoE install: its 25 W charging is far above what an 802.3af splitter supplies, so an 802.3af splitter may only trickle-charge it; check it at your screen brightness.
Apple iPad (A16): best for an Apple home
The iPad is the only tablet here where the kiosk and the battery limit both come from the vendor, with nothing to sideload. The Companion app’s Kiosk mode handles the dashboard, Guided Access keeps people out of everything else, and Apple’s 80% Limit stops charging at about 80% and resumes at 75%. Turn it on under Settings > Battery (the exact menu varies by iPadOS version). Apple notes the iPad will still charge to 100% now and then, but it is the cleanest answer to battery swelling in this guide.
Kiosk mode can wake on front-camera motion and drop to a blank screensaver, and Home Assistant can switch the screensaver and brightness while the app is open. What it cannot do is power the screen off the way Fully Kiosk does on Android, and Fully does not exist on iPadOS. At $399.99 it’s also the most expensive tablet here. Look elsewhere if you need a true screen-off, or if $400 is too much for a wall panel.
Amazon Fire HD 10: best budget panel
At $72.99 against a $154.99 list price, the Fire HD 10 is the cheapest 1920×1200 screen you can hang on a wall. Amazon promises security updates for at least four years from a new purchase from Amazon, so into late 2030 for one bought now, and Home Assistant owners have run Fire tablets on the wall for years. It’s a good panel for a hallway that just needs to show the alarm state and a few lights.
Fire OS is where it gets awkward. There is no Google Play. The Home Assistant app on the Amazon Appstore is the minimal build at 2026.6.1, months behind the 2026.8.4 stable release on GitHub. Fully Kiosk installs only from its APK. Its own FAQ says “We absolutely can’t recommend using Fire OS devices in any production environment.” We found no charge limit on Fire OS either, so pair it with the smart-plug automation below. Pass on it if a current app or a supported kiosk matters to you.
Lenovo Tab Plus Gen 2: best big screen
For a kitchen wall where people read the dashboard from across the room, the Tab Plus Gen 2 has the biggest screen here: 12.1 inches at 2560×1600 and 120 Hz, with Android 16 and Google Play. The Amazon listing pairs 8 GB of RAM with 256 GB of storage for $269.99, which is less than the smaller Samsung costs.
At about 775 g it is heavy, so plan to screw the mount into a stud rather than trust drywall anchors. Lenovo’s datasheet promises upgrades to Android 18 and security patches until 2030, far fewer upgrades than the seven SamMobile reports for the Samsung. We could not confirm a charge-limit setting on it, so treat it as a smart-plug tablet. Skip it if long software support matters more than screen size.
RAYPODO 10.1 PoE panel: one cable, no battery
A PoE wall panel removes the battery problem entirely. The RAYPODO runs Android 14 on a Rockchip RK3576S, takes power and data over one Ethernet cable, and its listing says it has no built-in battery and is designed for 24/7 use. Run that cable from a PoE switch and the panel has nothing to swell or wear out.
Trust is the trade-off. The listing does not state the PoE class or whether Google Play is certified, it has no customer ratings yet, and an older Android 11 RAYPODO panel sits at 2.8 stars from six ratings. The 8-inch WallSmart Pro panel at $253.99 is the alternative if you want one that fits a standard US or EU wall box, with a proximity sensor for wake. Skip both if you need a vendor update policy you can read before buying.
SONOFF NSPanel Pro 120: best in-wall switch replacement
The NSPanel Pro 120 replaces a light switch plate rather than hanging on the wall. It has a 4.7-inch 750×1334 screen, its own Zigbee 3.0 gateway, bridged to Home Assistant over Matter rather than acting as a ZHA or Zigbee2MQTT coordinator, and the Home Assistant app installs from its built-in F-Droid without rooting it. It needs mains wiring behind the plate, not PoE, so plan on an electrician if you aren’t comfortable with that.
For a full dashboard, its screen and chip are small. Reviews on SONOFF’s own product page call it really slow with a Home Assistant dashboard, so keep it to a few buttons. The 10-inch Shelly Wall Display XL at $349.99 is the bigger in-wall option, though owners of Shelly’s original Wall Display reported its built-in Home Assistant view crashing on the Shelly forum. For the full dashboard, a tablet does the job better.
One to watch: the new Alexa Tablet 11 at $329.99 is Amazon’s first tablet on full Android with Google Play, which would remove every Fire OS caveat above. It went on sale on October 14, 2026 and has few reviews, and Amazon has not published its update policy yet, so we’d wait before putting it on a wall.
Run power and data over one cable
Power is the other half of the link. A tablet plugged in at 100% charge for months is how batteries swell, and a long USB cable down the wall looks bad. Power over Ethernet fixes the cable, and our PoE explainer covers why an 802.3af port delivers at most 12.95 W at the device.
PoE Texas PoE to USB-C adapter: best way to power a regular tablet
The PoE Texas adapter turns an 802.3af port into USB-C power and data with a 36-inch right-angle cable, and its listing names iPad and Samsung tablets as compatible. At 10 W it should hold a tablet running a dimmed dashboard, though we did not measure that, so check the battery level at your brightness for a day. A tablet that drained overnight will take a while to recover on it. The 25 W PoE+ model suits tablets that charge faster, though it was not shipping when we checked.
The UCTRONICS USB-C splitter at $24.99 is the budget option, but it’s 5 V only with no USB Power Delivery, so check that your tablet charges from a plain 5 V source before you buy it. Skip PoE altogether if the panel sits next to an outlet; a smart plug on a normal charger is cheaper and lets Home Assistant control the charging.
Wire the charge window into Home Assistant
Any tablet without a charge limit needs Home Assistant to do the job: read the battery level and switch a smart plug to keep the battery between 30% and 80%. The obvious version uses two thresholds, and an owner in a Home Assistant community thread reported it failing “associated with a sensor becoming unavailable”. We built the automation on Home Assistant 2026.10.2 in Docker and tried to break it.
In the lab, a template sensor and a template switch stood in for the tablet’s battery sensor and the smart plug, so we could force each failure on demand. On a real panel the battery sensor comes from the Fully Kiosk integration or the Companion app, and the switch comes from your plug, so swap those two entity IDs for yours. This is the entry we ran. Append it to /config/automations.yaml and reload automations, or, in the UI editor under Edit in YAML, paste it without the first line and with the two leading spaces removed from every other line, since the editor sets the id itself:
- id: wall_tablet_charge_window
alias: Wall tablet charge window
mode: queued
triggers:
- trigger: numeric_state
entity_id: sensor.wall_tablet_battery
below: 30
- trigger: numeric_state
entity_id: sensor.wall_tablet_battery
above: 80
- trigger: state
entity_id: sensor.wall_tablet_battery
to: unavailable
for: "00:10:00"
id: lost
- trigger: time_pattern
minutes: "/15"
actions:
- choose:
- conditions:
- condition: trigger
id: lost
sequence:
- action: switch.turn_on
target:
entity_id: switch.wall_tablet_plug
- conditions:

entity_id: sensor.wall_tablet_battery
below: 30
sequence:
- action: switch.turn_on
target:
entity_id: switch.wall_tablet_plug
- conditions:
- condition: numeric_state
entity_id: sensor.wall_tablet_battery
above: 80
sequence:
- action: switch.turn_off
target:
entity_id: switch.wall_tablet_plugFour triggers do the work. The two thresholds handle normal charging, and the lost trigger switches the plug on once the sensor has been unavailable for 10 minutes, because a tablet with a flat battery can’t report anything. The 15-minute recheck runs the same conditions against the current level, whether or not anything crossed a threshold. We then drove the stand-ins through the REST API and logged what the plug did:
| Case | What we did | Plug afterwards | What fired |
|---|---|---|---|
| Drops low | Battery 50 to 25 | On | Below 30 threshold |
| Charges up | Battery 25 to 85 | Off | Above 80 threshold |
| Returns high | Sensor unavailable, back at 90 | Off | Above 80 threshold, on the return |
| Missed crossing | Plug on at 90, Home Assistant restarted | Stayed on | Nothing |
| Recheck | Waited for the quarter hour | Off at 17:30:00 | 15-minute recheck |
| Sensor lost | Battery 50, sensor unavailable | On after 10 minutes | Lost trigger |
We didn’t expect the third case. A numeric state trigger did fire when the sensor came back from unavailable already above 80, so a short dropout is not what breaks the simple version. The real gap is the fourth case: Home Assistant restarted while the plug was on, no threshold was crossed afterwards, and the plug stayed on. A charging tablet never drops back below 30, so without the recheck it would sit at 100% for good, which is exactly what the automation exists to prevent.
Verify the round trip
Once the panel is on the wall, check each direction of the link before you trust it. The request goes from the tablet to Home Assistant when someone taps the screen, and from Home Assistant to the tablet when an automation wakes it or cuts its power:
- Tap a light on the dashboard and confirm it switches, which proves the tablet’s user can call actions.
- Read the battery sensor in Developer tools > States and unplug the charger, then check the value drops within a few minutes.
- Switch the smart plug off from Home Assistant and confirm the tablet shows it’s on battery.
- On a Fully Kiosk panel, turn the screen off from its Home Assistant entity, then walk past the camera and confirm motion brings it back. If it does not, the device is suspending Fully with the screen off, so use the screensaver instead.
- Restart Home Assistant and check the panel reconnects by itself, without anyone touching it.
If the tablet passes all five, it’s ready for the wall. For the server behind it, our mini PC guide for Home Assistant covers hosts, and the Ubuntu install guide gets one running.
