What it does
See all featuresEnergy you can read
A live flow between solar, battery, grid, home and car. Charts for a day, a week, a month or a year. It uses the sensors from your Home Assistant Energy settings.
See it on the wallYour music library on the wall
Players, speaker groups, the queue, and your Music Assistant library: playlists, albums, artists, radio, search.
Blinds and gates you can see move
Blinds, curtains, gates and garage doors are drawn moving, from the position Home Assistant reports. Five drawing styles.
See it on the wallSecurity in one place
Alarm, locks, gates, doors and windows, cameras, and the smoke, gas and water sensors. Locks, gates and the alarm ask before they act.
See it on the wallEvery screen in step
Your setup is saved in Home Assistant, not in a browser. Each screen shows the common dashboard or one of its own, and changes reach the other screens.
See it on the wallTwelve languages
The interface speaks 12 languages, and device states use Home Assistant’s own words in the language you pick.
Steady when the network drops
If Home Assistant cannot be reached, the screen keeps your layout and says what is going on. It never replaces your setup with an empty page.
What it is
Nucleum Hub is a dashboard for Home Assistant. It is made for a tablet on the wall, and it works just as well on a phone or a laptop.
It shows what your Home Assistant already knows, room by room: lights, climate, doors and windows, the alarm, music, energy, the car. You read it at a glance and control it with a tap.
It does not replace Home Assistant. It is a new face for it. Your devices, automations and settings stay exactly where they are, and Home Assistant’s own dashboards keep working next to it.
A small integration, installed from HACS, puts Nucleum Hub in the sidebar of every screen.
Who it is for
- You run Home Assistant and want a screen the whole family can use, not only you.
- You have a tablet on the wall, or you are about to put one there.
- You would rather not write YAML or stack custom cards to get a good-looking dashboard.
- You have solar panels, a home battery or an electric car and want to see where your energy goes.
- You play music through Music Assistant and want your library on the wall.
Who it is not for. Nucleum Hub is a paid product, with support and updates. If you enjoy building your own dashboard from free cards, Home Assistant and its community already give you a lot. And if you do not use Home Assistant, Nucleum Hub cannot run.
How it works
Install from HACS
Add our repository to HACS with one click, download, restart Home Assistant and add the Nucleum Hub integration. No HACS? Unzip one file into your configuration folder instead.
Pick your screens
Open Nucleum Hub from the sidebar on the tablet, the phones and the computers you want. The setup assistant asks for your language and the pages you want, then shows the sensors it found so you can correct them. Each screen can show the common dashboard or one of its own.
Done
Your 60-minute trial starts on its own, or you paste your licence key in the integration’s settings. New versions arrive in Home Assistant under Settings › Updates, and you can go back to an earlier one from HACS.
From November 2026
Try it on your own home
- First, the demoThe demo runs the same screens on a made-up house, in your browser, for as long as you like. No Home Assistant needed.
- Then 60 minutesAdd the integration and the trial starts: every feature, on your own home, by the clock. No card, no e-mail.
- AfterNucleum Hub shows only the screen to activate a licence; your home keeps running in Home Assistant. Buy a licence and everything comes back, with your setup as you left it.
One trial per Home Assistant installation, and it needs internet to start. Before you add the integration, look around in the demo: it needs no Home Assistant and sends nothing anywhere. Open it on your own tablet too, to see how it runs there before you buy.
Your home stays at home
The dashboard talks to your Home Assistant, and to nothing else.* Its code loads nothing from the internet: no fonts, no scripts, no trackers, no analytics. It works on a tablet that has no internet at all, as long as it reaches Home Assistant.
Only our integration talks to our server, from your Home Assistant, and only for your licence and the trial. For the licence it sends a licence ID, a random home ID, a scrambled (hashed) ID of your Home Assistant installation and the version. Never your devices, rooms, names or states.
No telemetry. Diagnostics are a file you download yourself and decide whether to send.
Your setup lives in Home Assistant, so it is in your Home Assistant backups.
* One exception: music covers. They come through Home Assistant or the Music Assistant in your home, and a cover your screen cannot show (for example Apple TV artwork on an Android tablet) is converted inside your home by our integration. Only if that fails too does your screen fetch the picture from the music service on the internet, as a last resort, and you can switch this off in Settings.
Our licence server and the feedback we receive are stored in the EU. Privacy policy
