2-Pack USB Zigbee 3.0 Signal Relay

Dimensions: Not specified; Weight: Not specified; Capacity: 2 x functional repeaters; Material: PCB + plastic housing; Operating voltage: 1.8V–3.8V; Power input: 5V/1A via USB; Operating temperature: -10°C to 50°C; Operating humidity: up to 95% non-condensing; Wireless frequency band: 2.400–2.483 GHz; Wireless protocol: Zigbee 3.0 compliant. Each unit acts as an active Zigbee 3.0 router node — receiving, verifying, and retransmitting packets across the mesh. Supports automatic peer discovery and dynamic path selection, enabling robust communication across complex UK property footprints (e.g., terraced houses with narrow corridors or detached homes with outbuildings). Works without cloud dependency or mobile app — connects purely at radio layer. No configuration needed: simply insert into any USB socket near a weak-signal zone (e.g., basement utility room, upstairs bathroom, or garden shed) — it joins the network autonomously and begins relaying traffic within seconds. Ideal for renters and homeowners alike seeking permanent, low-maintenance coverage extension.
