The Pill by Shelly Analog

What is THE pill by shelly analog?

Add-on module for The Pill by Shelly that measures analog sensors and DC voltages up to 30 V. Ideal for monitoring batteries, power supplies, and other low-voltage devices.

Measurement range: 0-30 V DC
Extends The Pill’s measurement range for sensors and batteries
Compatible via 5-Terminal Add-on
1 Analog Input (AN) + 2 configurable Digital IOs (3.3 V logic)
5 V power output for connected sensors

*The Analog 0-30 V Add-on is sold separately and requires the 5-Terminal Add-on to connect with The Pill by Shelly.

Use Cases

Hobby Analog Sensor Monitoring

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.

Industrial Analog Sensor Integration

In professional environments, many systems rely on 0-10 V sensors to report critical measurements. By wiring these sensors into the Analog 0-30 V Add-on, The Pill by Shelly becomes your data bridge. It captures voltage levels from pressure, flow, or intensity sensors and sends them to the Shelly Smart Control app. You can then automate equipment, track process changes, or receive alerts when readings fall outside safe limits.

Voltage Monitoring for Battery Systems

In small battery-powered setups, even slight voltage changes can affect performance and reliability. With the Analog 0-30 V Add-on, The Pill by Shelly connects to your voltage sensors and gives you accurate real-time readings – whether it’s 3.7 V, 4.2 V, 12 V, 24 V, 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.

Caution

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