• The hub receives these signals, connects to your router via Ethernet or Wi-Fi, and enables remote access through the Tuya Smart app or integrated platforms like Google Home, Alexa, or Home Assistant.
• It also allows for inter-device automation, such as syncing the radiator valve with room temperature sensors, motion detectors, or schedules.

Without the hub, the valve can still operate locally (e.g., adjusting based on its built-in thermostat), but you won’t have remote control, app monitoring, or smart home integration.

Note: Make sure your chosen hub supports the Zigbee 3.0 or compatible protocol to ensure seamless pairing and stable performance.

Yes, the Tuya Zigbee radiator valve will continue functioning normally during a Wi-Fi outage, thanks to the decentralized nature of the Zigbee network.

Here’s what happens when your internet or Wi-Fi goes down:

• Local operation remains active: The valve continues to monitor room temperature and adjust heat output based on your preset schedules or manual settings stored in its memory.
• Zigbee network stays online: As long as the Zigbee hub has power (and the mesh network is intact), communication between devices persists without relying on Wi-Fi.
• App access is temporarily lost: You won’t be able to control the valve remotely or receive updates via the Tuya app until your internet connection is restored.
• Automation rules still run: Any local automations (e.g., “turn off when temperature reaches 22°C”) will continue working as programmed.

This resilience makes Zigbee-based smart heating systems more reliable than Wi-Fi-only devices, especially in areas with unstable internet connectivity.
