WHY THE PLUS ADD-ON?
Precise measurement and control
Shelly Plus Add-on is a galvanically isolated sensor interface for all Shelly Plus relays. Use the add-on to measure temperature and humidity via its 1-Wire connections or connect various analog and digital sensors for complex automations and higher efficiency.
Highly Compatible
The Shelly Plus add-on is compatible with most Arduino sensors! Use the digital or analog inputs to measure your desired parameters and create complex automation scenes based on the sensor data.
APPLICATION EXAMPLES
Control of the garage door
You can connect a reed switch sensor to the Shelly Plus add-on's digital sensor and track the status of your garage door. This way, you'll always know if it's open or closed and can react accordingly.

WATER HEATING
Heat your water to an optimal temperature
Cover your daily needs without wasting anything! With the Shelly PM relays you can determine the optimal energy requirement for heating the water in your instantaneous water heater. In conjunction with a temperature sensor, the Shelly relays can automatically switch off the instantaneous water heater when the optimal temperature is reached.
Recommended
Keep the heat in the house
Together with an LDR (photoresistor), the Shelly Plus Add-on can cause the Shelly Plus 2PM to close the blinds when direct sunlight is shining on your windows and heating up the room. This way, the air conditioning does not have to compensate for the heat by increasing power consumption, thus saving energy. And don't worry about losing the pleasant daylight! As soon as the sun changes location, the blinds will automatically open again.
Recommended
An awning that follows the weather
Motorized outdoor awnings provide pleasant shade for your guests on sunny days. However, a strong, uncontrolled wind can damage them beyond repair. By combining it with a wind sensor connected to the Shelly Plus add-on, Shelly Plus 2PM can automatically close the outdoor awning to protect it from wind. Additionally, the Shelly Plus add-on with a rain sensor can prompt the Shelly Plus 2PM to open the awning in time to protect your guests.
Recommended
Watering only when necessary
Having a beautiful garden is no easy task, and automating your irrigation system can save you time and optimize your costs. Together with a soil moisture sensor, Shelly Plus Add-on can make the Shelly Plus 1 turn on irrigation only when needed, skipping the rainy days.
Recommended
Motion-controlled lights
Shelly Plus Add-on can also be connected to a motion sensor to light up rooms that you occasionally use in the house. When you enter the room, the light will come on for as long as you need it.
