Product detailed description

🌡️ Miniature Smart Module for Ultimate Sensor Control

The Shelly Pill is a universal Wi-Fi and Bluetooth module housed in an incredibly compact body. It is conveniently powered via a standard USB-C port (5V) and, thanks to its tiny footprint, it can be hidden in places where space is severely limited. It delivers automation, monitoring, and Bluetooth Gateway functionality in the smallest form factor possible.

Out of the box, the device is ready for temperature monitoring with Plug and play compatibility for external temperature (DS18B20) or temperature/humidity (DHT22) sensors. Furthermore, it supports a wide array of digital or analog sensors and low-voltage actuators through external peripheral add-ons and highly configurable operating modes.

Ultra-light and Miniature Design

Its space-saving dimensions allow it to easily fit inside electrical boxes, behind cover panels, or be seamlessly integrated directly into the casings of other appliances and machinery.

Plug & Play Temperature Monitoring

Measuring temperature and humidity with DS18B20 and DHT22 sensors has never been easier. Receive precise data immediately upon connection without complex wiring or the need for additional hubs.

BLE Gateway Functionality

Utilize the Shelly Pill as an access gateway to seamlessly connect and integrate all your battery-powered sensors from the Shelly BLU product line.

Versatile Inputs and Outputs

Take advantage of independently configurable logic inputs or outputs supporting various voltage ranges for maximally versatile integration into your smart home.

DC Load Control & Analog Sensing

Control independent DC loads (up to 30V / 300mA) using an external SSR relay add-on for stable switching. You can also expand your automation by connecting analog sensors (0–5V), ideal for reading light levels, soil moisture, and other environmental parameters.
