Compact USB-C powered hub for sensors and automation

The Shelly Pill is a compact, ultra-versatile smart device designed to bring powerful automation and monitoring capabilities to even the smallest or most complex setups. Powered via USB-C (5V) and equipped with both WiFi and Bluetooth, it acts as a central bridge between your smart home system and a wide range of sensors, peripherals, and low-voltage devices. Whether you’re monitoring temperature, humidity, voltage, or controlling digital inputs and outputs, the Shelly Pill delivers reliable, real-time data and control in a form factor small enough to fit almost anywhere.

Built on Shelly’s Gen3 platform, it offers advanced features such as local actions, scripting, virtual components, and seamless integration with third-party systems via MQTT, WebSocket, and HTTP. Out of the box, it supports plug-and-play temperature and humidity monitoring using DS18B20 and DHT22 sensors, while its expandable design allows you to connect analogue sensors, digital inputs/outputs, and even control low-voltage DC loads with optional add-ons. It also functions as a Bluetooth gateway, extending communication with Shelly BLU devices and strengthening your overall smart ecosystem.

• Compact USB-C powered design for easy 5V installation
• Dual connectivity: WiFi and Bluetooth
• Built-in Bluetooth gateway for Shelly BLU devices
• Supports temperature, humidity, analogue voltage, and digital I/O monitoring
• Expandable with add-ons for advanced sensing and control
• Up to 3 configurable digital inputs/outputs (3.3V logic)
• Advanced automation via scripting, MQTT, WebSocket, and HTTP

From monitoring aquarium or pool temperatures to managing greenhouse climates, tracking battery voltage, or integrating custom sensors into your automation system, the Shelly Pill adapts effortlessly to your needs. It’s a flexible, low-power solution for anyone looking to extend smart control beyond standard devices, bridging the gap between sensors, systems, and intelligent automation with precision and ease.

  • Extremely small and lightweight device

    Mount it inside enclosures, behind panels, or integrate it within other devices thanks to its compact size.

  • Plug-and-Play Temperature Monitoring

    Simplify temperature and humidity sensing for DS18B20 and DHT22 sensors without complex wiring or additional hubs.

  • Acts as a Bluetooth Gateway

    Use the Shelly Pill as sn additional gateway device for all Shelly BLU series devices.

  • Supports Multiple Input & Output Types

    Take advantage of up to three independently configurable logic-level inputs or outputs and voltage ranges for versatile integration.

  • DC Loads Control

    Control two independent DC loads up to 30V/300mA using the external SSR add-on for reliable low-voltage switching in automation setups.

  • Analog Sensors Monitoring

    Connect 0-5V analog sensors for accurate readings of light, soil moisture, and other environmental parameters to enhance automation capabilities with an external add-on.

  • USB-C power design

    Save power and enable low-voltage environmental monitoring with a compact design suitable for always-on deployment. No heavy energy consumption.

  • A versatile device

    Use it as a standalone solution or as part of a larger system on third-party platforms. No hardware clutter or complex installation.

  • Peripheral Add-on Compatibility

    Expand the Shelly Pill’s integration and control capabilities with peripheral add-ons for digital inputs, outputs, and analogue sensing.

  • Bridging Peripherals to Home Automations
