The Pill by Shelly

The Pill by Shelly is a compact, multi-purpose low-voltage Wi-Fi and Bluetooth device, powered by just 5 V via USB-C. Its small form factor makes it easy to fit into any space-constrained environment. The device is ready to use with plug-and-play temperature sensors (DS18B20) or temperature and humidity sensors (DHT22). With configurable peripheral modes and external add-ons, The Pill also functions as an analog voltmeter, digital I/O controller, or DC load switcher – all in one compact unit. Set up and controlled via the Shelly Smart Control app or your preferred smart home platform. Compatible with Home Assistant, Athom Homey, Samsung SmartThings, Google Home, and Amazon Alexa. Shelly devices operate 100% locally and only require a local network to function. Use Cases: Temperature monitoring – track pools, aquariums, water tanks, or server cabinets with up to five DS18B20 temperature probes simultaneously, Temperature & humidity – maintain optimal conditions in greenhouses, warehouses, or server rooms using a DHT22 sensor, Digital sensors – connect door reed switches, motion sensors, or water level detectors directly to your smart home system, DC voltage monitoring – measure battery levels (3.7 V, 12 V, 24 V) with the Analog 0–30 V Add-on, DC load control – switch LED indicators, small fans, or solenoid valves on and off with the SSR Add-on, Bluetooth Gateway – acts as a gateway for Shelly BLU devices, extending coverage across your smart home, Accessories and expansion options: The Pill by Shelly expands with five accessories covering everything from simple temperature measurement to advanced analog sensor reading and DC load control: Shelly Temp.
