When you need to switch low-voltage devices, the SSR Add-on lets you control them through The Pill by Shelly. Connect small fans, LED indicators, solenoids, or other 30V DC loads to the add-on's outputs, power the Pill, and link it to your Shelly Smart Control app. Each channel can be automated based on sensor data, schedules, or scenes - so your devices turn on exactly when needed. The Pill by Shelly simply sends the command, and the add-on switches the load safely and reliably.
