openHAB plus a wearable-first interface
TechRexOS focuses on simple home actions that make sense on a watch. openHAB can remain the automation platform while the watch provides a dedicated user interface.
MQTT as the common link
TechRexOS is designed around MQTT-based communication. That makes openHAB a natural integration direction without forcing the watch UI to become openHAB-specific.
Local home automation
TechRexOS follows a local-first approach, matching users who want their automation and wearable control to continue relying primarily on the local network.
A watch is a control surface, not the whole Smart Home
Complex rules and administration belong on larger screens. The watch should deliver quick commands, useful states and clear feedback.
TechRexOS Studio
The planned web configuration environment will provide a more convenient way to choose the devices, views and integration settings available on the watch.
