If you enjoy building small DIY projects, the Analog 0-30 V Add-on lets you attach your favorite hobby sensors straight to The Pill by Shelly. Plug in a soil moisture probe, a light-sensitive LDR, or a simple sound sensor and see the values appear in the Shelly Smart Control app. Use them to start watering, turn on lights, or trigger custom actions. The Pill simply reads your sensor’s output and turns it into automation you can control.
