Galvanically isolated sensor interface for all Shelly Plus relays. Use it to measure temperature and humidity or connect various analog and digital sensors. Also compatible with most Arduino sensors!

Attach To Shelly Plus and Gen3/4 Devices For Expanded Functionality

Expand the functionality of Shelly Plus and Shelly Gen3/4 devices with the Shelly Plus Add-On module. This module is designed with a galvanically isolated sensor interface, which allows no direct electrical connection between the power side of the attached Shelly device and sensor. This ensures signal integrity when connecting to external sensors and provides protection if the sensor fails or shorts out, preventing damage to the attached Shelly device or wiring in your household. The Plus Add-On module is built with an analog input, a digital input, one reference voltage input, one reference voltage through a pull-up resistor output, and two ground terminals. You can use it to measure temperature and humidity and automate actions based on connected sensors (analog or digital). The Shelly Plus Add-On module receives power directly from the attached Shelly device and supports m
