Inteligentný spínač Shelly 1 Mini Gen4 1P bezdrôtový 110–240 V 50–60 Hz 1,2 W Bluetooth Wi‑Fi ZigBee 34×16×29 mm

The Shelly 1 Mini Gen4 is a compact single‑pole wireless smart relay controller (29 x 34 x 16 mm) designed for installation inside wall/junction boxes, behind switches or in other confined spaces. It provides a potential‑free (dry) NO contact for galvanically isolated control of lighting, gates, bells, relays and other automation devices, and supports local and remote control, schedules, scenes and scripts. The device integrates with major ecosystems such as Google Home, Amazon Alexa and Samsung SmartThings and supports Wi‑Fi, Zigbee, Bluetooth and Matter protocols.

Advantages

The controller combines multiple radio interfaces — Wi‑Fi (802.11 b/g/n), Zigbee (802.15.4) and Bluetooth 5.0 — and can act as a BLE gateway and Wi‑Fi/Zigbee signal booster for other IoT devices. Matter compatibility extends integration options across ecosystems. It supports mains switching up to 240 VAC and low‑voltage switching up to 30 VDC through a potential‑free NO relay, includes an internal temperature sensor and contains an ESP‑Shelly‑C68F microcontroller with 8 MB flash for scripting and real‑time tasks. The compact plastic housing and small dimensions make it suitable for tight installation spaces.

Suitable for

• Remote and local switching of lighting and small appliances
• Integration into Zigbee or Matter smart home ecosystems
• Control of gates, bells or relays requiring galvanic isolation
• Installation inside junction/wall boxes or behind switches

How to use

Install the Shelly 1 Mini Gen4 inside a compatible junction or wall box in accordance with local electrical regulations. Connect supply and load following the wiring diagram, observing the maximum current and voltage ratings and using recommended cable cross sections (0.2–2.5 mm²). Configure the device with the Shelly Smart Control app or via the built‑in web interface; optionally add it to a Zigbee or Matter ecosystem. Create schedules, scenes or scripts in the app or integrate via HTTP/HTTPS, MQTT, WebHooks or KNX net/IP APIs for local or remote automation.

Recommendations

Use appropriate external protection (circuit breaker with B or C characteristic, rated current max. 10 A) and ensure connections are tightened to the specified torque (0.4 Nm). Do not exceed the relay’s maximum switching current and observe the device’s operating temperature and humidity limits. For mains work, installation should be performed by a qualified electrician.
