Shelly Plus Addon Add-on (accessory/actuator for the entire Plus series) is a next-generation sensor that allows the connection of an infinite number of tools. Through a single device, you can connect up to 5 DS18B20 temperature probes or a DHT22 sensor for monitoring temperature and humidity.
Designed to simplify installation, it can be attached using clips on the desired Plus module. Various sensors and actuators can be connected: temperature, humidity, motion, brightness, etc.
Shelly Plus Add-on is a galvanically separated sensor interface for all Shelly Plus devices. You must have any device from the Shelly Plus family.
Device equipped with Wifi. No HUB is required for smartphone management.
It has both analog and digital input.
Compatibility: Shelly Plus Add-On is compatible with Amazon Alexa, Google Home, Samsung SmartThings, Android, and iOS.
It features both analog and digital inputs, so by connecting it with various sensors you can:
» Know the real-time status of your garage door.
» Measure precise temperature inside the aquarium or environment.
» Automatically raise/lower blinds based on room brightness.
» Automatically close outdoor blinds to protect them from wind.
