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.
