The Shelly Analog 0–30V Add-on is an expansion module for The Pill by Shelly multi-purpose input device, enabling the measurement of analog voltages in the 0–30V range. It significantly extends the base device’s built-in 0–2.5V measurement range, allowing The Pill by Shelly to monitor various DC systems, batteries, and analog sensors.
The module is especially useful in applications where precise voltage monitoring is important, such as solar systems, batteries (3.7V, 12V, 24V), industrial sensors, or other low-voltage systems. When used together with The Pill, it provides a flexible and scalable measurement solution that can be easily integrated into smart home or industrial automation environments.
Thanks to its Plug & Play design, the add-on can be connected quickly and put into operation immediately. This solution is primarily recommended for DIY users building more complex measurement and automation systems.
