Smart switch Shelly 1PM Mini Gen4, wireless 110–240V AC, max 8A / 2000W, plastic housing 34×16×29 mm

The Shelly 1PM Mini Gen4 Zigbee Matter is a compact smart relay with integrated power monitoring designed for home automation. It supports Zigbee, Wi‑Fi, Bluetooth and Matter, offers local and cloud control, and integrates with platforms such as Google Home, Amazon Alexa and SmartThings. The small plastic housing (34 × 16 × 29 mm) fits into standard wall boxes and behind switches, enabling remote switching, energy measurement and automated scenarios via the built‑in web interface without additional software.

Advantages

This unit combines a single‑pole relay and an energy meter in one compact device, allowing remote ON/OFF control and accurate power consumption measurement. It supports multiple protocols (Zigbee, Wi‑Fi, Bluetooth, Matter) and common integration methods (MQTT, HTTPS, WebHooks, UDP, local APIs) for flexible integration into various smart home ecosystems. The device includes protections against overvoltage, overload, over‑power and overheating, uses an ESP‑Shelly‑C68F microcontroller with 8 MB flash for stable operation, and can act as a network repeater to extend Zigbee or Wi‑Fi coverage.

Suitable for

• Remote switching of lighting and small household appliances
• Monitoring and logging power consumption of connected loads
• Installation in wall boxes or behind wall switches where space is limited
• Integration into Zigbee, Matter or Wi‑Fi based smart home systems

How to use

Install the Shelly 1PM Mini Gen4 inside a compatible wall box or behind a switch following local electrical safety rules. Connect the device to the mains (110–240 V AC) and wire the load to the relay output. Configure network and automation settings using the built‑in web interface, Bluetooth setup or through your preferred platform (Zigbee coordinator, Matter controller or Wi‑Fi). Create schedules, webhooks or Shelly Script automations as required, and enable MQTT or local APIs for advanced integrations.

Recommendations

Use circuit protection with B or C characteristic and appropriate rated current (recommended max 10 A) and ensure correct wire size (0.2–2.5 mm²). Place the unit in a well‑ventilated wall box within the specified temperature and humidity ranges. For optimal wireless performance, verify placement for signal coverage and consider using the device’s repeater capability in larger Zigbee or Wi‑Fi networks.
