Add on to your Shelly Plus devices.

The Shelly Plus 1 Add-On can accommodate up to five DS18B20 sensors or one DHT22 sensor. The Add-On has both an analog and digital input to ensure accurate measurements. Choose to include the DS18B20 temperature sensor (up to 5) or the DHT22 sensor for monitoring both temperature and humidity.

Why choose the Shelly Plus Add-On? It provides precise measurement and control, serving as a galvanically isolated sensor interface for all Shelly Plus relays. Use the 1-Wire terminals to measure temperature and humidity, or connect a variety of analog and digital sensors for advanced automation and increased efficiency.

Shelly devices are fully compatible with Alexa, Google Home, Android and iOS, allowing you to command them with just your voice. Use the convenient Shelly Smart Control app to manage your spaces, energy usage, and expenses.

 

USE CASES

LIGHTING

Easily connect the motion-controlled lights of Shelly Plus 1 Add-On to a PIR sensor in occasionally used rooms in your home. This will ensure that the lights turn on when you enter the room and stay on as long as you need.

 

IRRIGATION

Save time and optimise costs with automated irrigation. Shelly Plus 1 Add-On, paired with a soil moisture sensor, only turns on when needed - even skipping rainy days - to help your garden thrive. Recommended with Shelly Plus 1PM

 

AWNINGS

Protect your guests from unexpected weather conditions by connecting a wind sensor and rain sensor to automatically open or close your motorised awning. Recommended with Shelly Plus 2PM


AQUARIUM COMFORT

Use Shelly Plus Add-on and two DS18B20 sensors to accurately monitor the temperature of your aquarium and the room. This allows you to maintain a healthy and comfortable environment for your pets. You can also add a liquid level sensor to the Add-on for peace of mind knowing the optimal water level is maintained.

Recommended with Shelly Plus 1PM.
