Why the pill by shelly Micro usb to 5 terminal add-on

5-Terminal Add-on exposes The Pill by Shelly’s full hardware potential, giving you access to all logic-level I/Os and power terminals.

Whether you’re connecting sensors, creating automation logic, or testing new setups, it provides a simple and reliable interface for any smart project.

Use Cases

Make Buttons and Digital Sensors Smart

Using the 5-terminal Digital Adapter, you can connect simple switches and sensors directly to The Pill by Shelly. Wire a reed switch to detect door openings, attach a pushbutton to trigger scenes or webhooks, or use a float switch to know when a tank is full or empty. Once connected, the Pill sends each change to the Shelly Smart Control app, where you can automate lights, pumps, alerts, or any action you need. A quick way to turn basic contacts into smart triggers.

Smart Control for Small Wired Devices

With the 5-Terminal Adapter, you can use The Pill by Shelly to drive simple low-voltage outputs. Connect LEDs for status signals, buzzers for alerts, or small relays that trigger other devices. You can also automate blinds, valves, or other low-power actuators by wiring them to the output terminals. Once connected, every action can be controlled through the Shelly Smart Control app or combined with sensor data to create smart on/off automations tailored to your setup.

Caution

Installation of certain Shelly devices must be done by a qualified electrician or authorised installer.
