The transmission range of the Noorio sensors in an open environment can reach up to 656 ft (200m), or go across 3 walls. However, the actual range could be varies depending on the following conditions.
Building materials & structures: Reinforced concrete could block more single compared to wood.
Obstacles in rooms: Furniture, doors, and windows could potentially reduce the transmission range.
Installation location of the smart hub: If the smart hub was installed in a corner, or blocked by other obstacles, it could affect the transmission range.
