Shelly, The Pill

The Pill by Shelly – The Swiss Army Knife for Smart Homes

"The Pill" is a compact, highly versatile tool from Shelly, engineered to meet the needs of smart home installers and IoT enthusiasts. Despite its coin-sized form factor, it packs the power of the Shelly Gen3 ESP32-C3 microcontroller with 8MB of flash memory. Powered conveniently via USB-C, it serves as a portable hub, a debugger, and a powerful testing unit.

This device is designed for flexibility. Use it as a standalone Bluetooth gateway to bridge BLE sensors to the cloud, or attach modular add-ons to measure voltage, control relays, or read temperature data. Its scripting capabilities allow you to run custom logic locally, making it an indispensable tool for on-site troubleshooting and development.
