The Pill by Shelly

The Pill by Shelly | Compact Wi-Fi & Bluetooth Sensor Automation Device The Pill by Shelly is a compact, multi-purpose low-voltage Wi-Fi and Bluetooth device designed for smart monitoring, automation, and sensor integration. Powered by 5V via USB-C, its ultra-small form factor makes it ideal for space-constrained installations, DIY projects, and low-voltage smart control applications. Use it for plug-and-play temperature monitoring with compatible DS18B20 temperature probes or DHT22 temperature and humidity sensors. The Pill also supports a wide range of digital and analog sensors, low-voltage actuators, and external add-ons for expanded functionality. Key Features Compact low-voltage smart device USB-C powered, 5V Wi-Fi and Bluetooth connectivity Supports DS18B20 temperature sensors Supports DHT22 temperature and humidity sensor Up to 5 temperature probes supported Digital input/output modes Built-in analog input for 0–2.5V DC measurement Supports external Analog 0–30V Add-on Supports external SSR Dual-Channel Add-on Bluetooth Gateway for Shelly BLU devices Supports MQTT, WebSocket, HTTP, scripting, schedules, and local actions Works with Shelly Gen3 features and automation capabilities Smart Monitoring & Automation The Pill by Shelly is perfect for monitoring water temperature in pools, aquariums, water tanks, and reservoirs. It can also be used for room temperature and humidity monitoring in server cabinets, greenhouses, warehouses, and other areas where environmental conditions matter. With configurable digital inputs and outputs, The Pill can also read simple sensors such as door reed sensors, motion sensors, and water state sensors. For advanced setups, optional add-ons allow DC voltage monitoring up to 30V or control of small DC loads such as LED indicators, fans, solenoids, and valves.
