Features
Extremely small and lightweight device
Mount it inside enclosures, behind panels, or integrate it within other devices thanks to its compact size.
Plug-and-play temperature monitoring
Simplify temperature and humidity sensing for DS18B20 and DHT22 sensors without complex wiring or additional hubs.
Acts as a Bluetooth gateway
Use The Pill by Shelly as additional gateway device for all Shelly BLU series devices.
Multiple input/output types support
Take advantage of up to three independently configurable logic-level inputs or outputs and voltage ranges for versatile integration.
DC loads control
Control two independent DC loads up to 30V/300mA using the external SSR add-on for reliable low-voltage switching in automation setups.
Analog sensors monitoring
Connect 0-5V analog sensors for accurate readings of light, soil moisture, and other environmental parameters to enhance automation capabilities with an external add-on.
USB-C power design
Save power and enable low-voltage environmental monitoring with a compact design suitable for always-on deployment. No heavy energy consumption.
A versatile device
Use it as a standalone solution or as part of a larger system on third-party platforms. No hardware clutter or complex installation.
Peripheral add-on compatibility
Expand The Pill by Shelly’s integration and control capabilities with peripheral add-ons for digital inputs, outputs, and analog sensing.
Bridging peripherals to Home Automations
Enable The Pill by Shelly to connect peripheral devices to your automation platform and expand system behavior and control.
Use Cases
Water Temperature Monitoring
Monitor aquariums, pools, boilers, water tanks, or other liquids with precise temperature readings. The Pill by Shelly connects to your water temperature sensors and sends real-time data to the Shelly Smart Control app. Use it to automate heating systems – when the temperature drops, you can trigger pumps or heaters to maintain optimal conditions. Ideal for stabilizing aquatic ecosystems, keeping pool water comfortable, and improving energy efficiency.
Air & Greenhouse Climate Monitoring
Whether you’re maintaining a healthy indoor environment or creating optimal conditions for plant growth, The Pill by Shelly delivers accurate temperature and humidity data using the DS18B20 or DHT22 sensors. Real-time measurements in the Shelly Smart Control app help you automate HVAC systems, thermostats, humidifiers, or greenhouse ventilation. Keep living spaces comfortable and ensure stable conditions for your plants – all with one compact monitoring hub.
Voltage Monitoring for Battery Systems
In small battery-powered setups, even slight voltage changes can affect performance and reliability. With the Analog Add-on, The Pill by Shelly connects to your voltage sensors and gives you accurate real-time readings – whether it’s 3.7V, 4.2V, 12V, 24V, or other low-voltage sources. The moment levels shift, data reaches your Shelly Smart Control app, helping you react before power issues occur. Keep your batteries, UPS units, and backup systems stable and running longer.
Flexible Automation for Unique Setups
Every smart setup has its own logic, and with The Pill by Shelly, you can build yours exactly the way you want it. With extensive scripting capabilities and flexible peripheral modes, it easily adapts to specific sensors, actuators, or workflows. From a tailored home automation routine to a custom business control system, The Pill gives you the freedom to experiment, fine-tune, and bring unique ideas to life.
Create automations that think your way.
Caution
Installation of certain Shelly devices must be done by a qualified electrician or authorised installer.
