LUMA-6CH / Local control
What local-first control actually means.
How we prepare and verify this contentLocal-first means essential functions execute on the device or inside its owner's network. The internet may add updates or services the customer chooses, but it is not required to switch on a light, change a scene or retain settings.
Local-first is behavior, not a label.
A product with Wi-Fi is not automatically cloud-based, and a product with an app is not automatically smart. The useful question is simpler: which operations stop working when the internet connection is removed?
For a lighting controller, switching, dimming, scenes, physical inputs and stored configuration are essential functions. A local-first architecture keeps them close to the load and under the installation's control.
| Function | Where it should work | Internet required |
|---|---|---|
| Switching and dimming | On device | No |
| Wall inputs | On device | No |
| Routine configuration | Local network | No |
| Firmware updates | Vendor server, when requested | Yes, only to download |
Even a dimmer produces sensitive data.
Switching times, occupied rooms and sensor responses can describe presence and habits. The most robust way to protect this data is not to transfer it without a need.
Local processing does not remove every risk: the device still has to protect credentials, firmware and network access. It does reduce the problem's surface because operational data does not need to cross external infrastructure to execute a local command.
Connected should not mean dependent.
A local-first system can communicate with Home Assistant, Node-RED or services selected by its owner. The difference is the direction of that relationship: an integration extends the product; it does not grant permission for the product to operate.
Documented protocols and APIs reduce lock-in, but they need a clear security model. A local endpoint without authentication does not become safe merely because it is outside the cloud.
Current product status. Complete LUMA-6CH integrations, API endpoints and authentication scheme are still being defined for the pre-production revision. Public documentation marks those items explicitly as TBC.
Updates and diagnostics should remain a choice.
Signed firmware and verified updates protect a device, but the update channel should not become a remote switch over the product. The owner should be able to decide when to update and keep using essential functions if the server is unavailable.
Diagnostics can help identify abnormal temperature, errors or uptime problems. It should have a precise purpose, collect the minimum required and remain switchable.
The simplest test: remove the internet.
A local-first design should explicitly define behavior without WAN, DNS, vendor servers and mobile applications. Not every service can continue, but essential behavior should remain predictable.
- Physical inputs continue to control outputs.
- Previously stored configuration remains available.
- A network error does not leave the load in an undefined state.
- Network recovery does not silently replace local configuration.
This is the promise we want to make testable with LUMA-6CH: connectivity is a product capability, not a condition of ownership.
