™Get started
First the demo, for as long as you like. Then 60 minutes with every feature, on your own home. No card, no e-mail. Here is the whole way, from nothing to a dashboard on the wall.
Nucleum Hub goes on sale in November 2026: the integration and the trial open that day. Until then, try the demo.
Before you add the integration
The trial starts the moment you add the integration and runs by the clock, so get these ready first:
- Look around in the demo. The demo runs the same screens on a made-up house. Open it on the wall tablet too, in the browser you will use there: if it runs well, Nucleum Hub will too.
- Your rooms. Room cards come from your Home Assistant areas. Put your lights, sensors and devices in areas first.
- Your energy, if you have solar or a battery. Nucleum Hub uses the power sensors from Home Assistant’s Energy settings, and finds them itself when there are none.
- An administrator account on Home Assistant, for the install and the first start.
1. Install
With HACS: add our repository to HACS as a custom repository, with one click through My Home Assistant, download, restart Home Assistant, then add the Nucleum Hub integration in Settings › Devices & services. Without HACS: unzip one file into your configuration folder, restart and add the integration the same way. The steps, one by one, are in Install.
2. Open it and set it up
Open Nucleum Hub from the sidebar. The setup assistant takes three steps: your language and a name for the greeting, the pages you want, then what it found in your home, which you can correct. Press Create dashboard: your setup is saved in Home Assistant, so every screen shows the same. Quick start
3. The trial
- It starts on its own when you add the integration: 60 minutes by the clock, every feature, on one home. No card, no e-mail.
- Once per Home Assistant installation. Our server remembers it, so reinstalling does not start it again. Your Home Assistant needs internet to start it.
- When it ends, Nucleum Hub shows only the screen to activate a licence, with a button to Home Assistant. Your home keeps running, and you control it from the Home Assistant app.
- Buy a licence and everything comes back on the spot, with your setup as you left it.
4. Buy and activate
Pick a plan on the pricing page. Paddle, our reseller, takes the payment; your licence key comes from us by e-mail right after. In Home Assistant, open Settings › Devices & services › Nucleum Hub › Configure and paste it. Licence and activation
