## Description

The Shelly Plus Add-On is a sensor interface add-on, compatible with all Shelly Plus devices. Engineered to measure integrate temperature and humidity levels using its 1-Wire terminals, or connect analogue and digital sensors for complex automation based on rainfall or wind speed.

The Shelly Plus Add-On is a galvanically isolated sensor interface compatible with all Shelly Plus devices. It serves to enhance the levels of customisation and automation behind your Shelly network even further by including support for both analogue and digital sensors, opening up the possibilities of advanced and sophisticated automations even further by providing opportunities for integrating light sensors, humidity monitors or wind speed, and relaying this information to your Shelly devices to adjust your smart home accordingly.
The Shelly Plus Add-On can enhance your automation anywhere from intelligent sprinkler systems that activate according to soil moisture levels, to motion-controlled lights for rooms that are only used occasionally - the possibilities are endless!
