You’ve seen the photos. A sleek, glowy screen sits flush against a kitchen backsplash or right next to the front door, looking like something out of a sci-fi movie. It looks effortless. But honestly? Getting a tablet for wall mount right is actually a massive headache if you don't think about the three things everyone forgets: power, heat, and software rot.
Most people just grab an old iPad, slap some Velcro on the back, and call it a day. Then, six months later, the battery is bloated because it stayed plugged in 24/7, or the screen is perpetually frozen because the WiFi signal can’t penetrate the drywall and the mounting bracket. It’s annoying. If you're building a smart home dashboard or a dedicated video conferencing hub, you need to stop thinking about it as a "tablet" and start thinking about it as a built-in appliance.
The Great Power Struggle: Batteries are the Enemy
Here is the thing about lithium-ion batteries: they hate being full. When you use a tablet for wall mount and leave it on a charger indefinitely, you are basically asking for a "spicy pillow"—that terrifying phenomenon where the battery swells and cracks the screen.
I’ve seen dozens of DIY setups where the user didn't use a power management tool. If you are using an Android tablet, look into an app like Fully Kiosk Browser. It has features that can talk to a smart plug to turn the power on when the battery hits 20% and off at 80%. This one step alone will triple the lifespan of your hardware. iPads are a bit more stubborn, though modern versions of iPadOS have "Battery Health Management" that kicks in when it detects a constant power source, lowering the maximum charge level automatically. It’s better than nothing, but it’s still not a perfect solution.
PoE is the Secret Sauce
If you are doing a renovation or have attic access, stop messing with USB cables. Power over Ethernet (PoE) is the professional way to do this. You run a single Cat6 cable to the wall opening, use a PoE-to-USB converter (like those from VidaBox or Mount-It!), and you get data and power in one line. It’s stable. It doesn't drop signal. It just works.
Selecting the Right Glass
Not all tablets are created equal for wall duty. You might think the latest iPad Pro is the move, but that’s overkill. You’re paying for a processor that will spend 99% of its life displaying a weather widget and some lightbulbs.
The Samsung Galaxy Tab A series is a darling in the home automation community for a reason. They are thin, relatively cheap, and the bezel size is consistent, making it easier to find high-quality frames. On the flip side, the Amazon Fire HD 10 is the budget king. You can usually find them for under $100. However, the software is a nightmare of ads unless you use something like the "Fire Toolbox" to strip it down to pure Android.
Then there is the dedicated hardware. Companies like Control4 or Crestron sell touchpanels specifically designed to be a tablet for wall mount. They don't have batteries. They are designed to be "always on." They cost five times as much as an iPad, but you’ll never have to worry about the house burning down because a cheap battery failed.
Why Cheap Mounts Are a Trap
You can find a $15 plastic mount on Amazon in five seconds. Don't do it. Cheap mounts usually have terrible cable management. You’ll end up with a messy cord dangling down your wall like a tech-themed tail.
A proper mount should be:
- Recessed: The tablet sits inside the wall, nearly flush.
- Metal: Plastic warps over time, especially with the heat generated by a screen that never turns off.
- Ventilated: Screens get hot. If there is no airflow behind that tablet, the processor will throttle, and your "smart home" will feel like it’s running through molasses.
MB Mounts and Vidabox make enclosures that actually look like part of the architecture. They use magnetic faceplates, so if the tablet freezes (and it will), you can pop it off, hard reboot it, and snap it back on without needing a screwdriver.
The Software Ghost in the Machine
Most people spend all their time on the hardware and zero time on the interface. A wall-mounted tablet shouldn't just be a home screen with apps. That’s clunky. You want a dashboard.
Home Assistant is the gold standard here. With their "Lovelace" UI, you can create a floorplan view of your house. Tap the bedroom on the screen, the lights go off. It’s intuitive. If you aren't a coder, ActionTiles for SmartThings or Hubitat are great alternatives.
The goal is "Zero Interaction Friction." If you have to unlock the tablet, find an app, wait for it to load, and then press a button, you might as well have just walked across the room and flipped the physical switch. Your tablet for wall mount needs to be "Always On" or use a proximity sensor (like the tablet's front camera) to wake up the second you walk by.
Placement Politics: Where Does it Actually Belong?
Don't just put it where you have an outlet. That is a recipe for a tablet you never use.
The kitchen is the obvious choice—recipes, timers, grocery lists. But mounting it at eye level while standing is different from eye level while sitting. If it’s in a hallway, it should be near a "transition point," like the door to the garage. You want to see the traffic report or the security camera feed as you're grabbing your keys.
Avoid placing them directly opposite windows. The glare on a tablet screen is significantly worse than on a TV because tablets aren't usually treated with high-end anti-reflective coatings. You’ll end up staring at a reflection of your own face instead of your thermostat settings.
The Hidden Cost of "Always On"
Electricity isn't the concern—these things pull pennies a month. The real cost is "Burn-In."
OLED screens are beautiful. The blacks are deep, the colors pop. But if you leave a static image (like a clock or a menu bar) on an OLED screen for 24 hours a day, those pixels will eventually "ghost." You’ll see a faint outline of the time even when you’re watching a video. For a tablet for wall mount, an LCD screen is actually superior. It’s more durable for static displays. If you must use an OLED (like on a high-end Samsung or iPad Pro), make sure your dashboard software has a "screen saver" mode that moves images around by a few pixels every few minutes.
Actionable Steps for a Professional Setup
Setting this up isn't a weekend project if you want it to look good. It's a process.

- Audit your WiFi. Before cutting a hole in your wall, hold your tablet in that exact spot. Check the signal strength. Walls are full of pipes, wires, and studs that eat 5GHz signals for breakfast.
- Pick your ecosystem. If you are an Apple house, stay with an iPad. Mixing an Android wall tablet with an iPhone-only family leads to "I don't know how to use this" complaints from your spouse or kids.
- Use a "Dogbone" recessed outlet. If you aren't doing PoE, install a recessed media box (like the ones from Arlington). This gives the USB brick a place to hide behind the tablet so the mount can sit flush.
- Disable all "bloat." Turn off notifications for everything except the essentials. You don't want your wall screaming at you because you got an email from a newsletter you forgot to unsubscribe from.
- Set up a "Guest" profile. If you use Home Assistant or another dashboard, make a specific user for the wall tablet. This prevents guests from accidentally deleting your automations while trying to turn up the music.
Think of the wall-mounted tablet as the "Brain" of the room. It should be invisible when you don't need it and instantaneous when you do. Anything less is just a glorified picture frame that needs to be charged.
