Where you'd use it
Wiring External Sensors to the Pill
Use the 5-Terminal Add-on's digital and analogue I/O to connect push buttons, float switches or door sensors directly to a Shelly Pill for custom automations.
Adding Temperature and Humidity Sensing
Wire in a DS18B20 or DHT22 sensor to give a Pill-based project accurate environmental readings alongside its other functions.
Foundation for Further Add-Ons
Fit it first as the required base module before adding accessories such as the SSR Add-on, since it's the interface that unlocks the Pill's expansion options.
