The Shelly Plus Add-on is a highly compatible and versatile sensor interface that works seamlessly with Shelly Plus devices. With support for up to five DS18B20 sensors or one DHT22 sensor, the Add-on allows for precise temperature and humidity measurements. It also features an analog and digital input, making it perfect for a wide range of applications such as garage door position monitoring, water heating management, light control based on luminosity, and more. Enhance your smart home experience with the Shelly Plus Add-on and enjoy endless automation possibilities.

Shelly Plus Add-On Use Cases:

Garage door position monitoring:

Connect a reed-switch sensor to the digital input and track the state of your garage door, knowing whether it’s open or closed when you’re away.

Aquarium temperature and water level monitoring:

With two DS18B20 sensors, you can measure the temperature inside your aquarium and the room temperature. You can also connect a liquid level sensor to ensure optimal water levels.

Light control based on luminosity:

Using an LDR (photoresistor) and the Shelly Plus Add-on, control your lights based on the room’s brightness.

Weather-responsive awning control:

Combine the Shelly Plus Add-on with a wind sensor to automatically close outdoor awnings in strong winds, or with a rain sensor to open the awning just in time to protect your guests.

Smart irrigation:

Use a soil moisture sensor with the Shelly Plus Add-on to control your irrigation system based on actual soil moisture levels, saving time and optimizing costs.

Motion-controlled lights:

Connect a PIR sensor to the Shelly Plus Add-on to automate lighting in rooms that are occasionally used, turning lights on only when someone is in the room.
