The Pill by Shelly
The Pill by Shelly is a compact USB-C powered automation controller designed for monitoring sensors, collecting environmental data, and interfacing with low-voltage devices. Combining Wi-Fi and Bluetooth connectivity with the flexibility of the Shelly Gen3 platform, it provides a powerful foundation for custom automation, monitoring, and control projects.
Designed for integration with temperature sensors, humidity sensors, voltage monitoring devices, and digital inputs and outputs, The Pill can act as a standalone monitoring device or become part of a larger automation system. Built-in support for scripting, local actions, MQTT, WebSocket, and HTTP APIs makes it suitable for advanced smart home, energy monitoring, and industrial applications.
Its modular design allows functionality to be expanded through compatible add-ons, enabling digital I/O control, analog sensing, and high-accuracy voltage measurement for a wide range of custom solutions.
