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 ports, or connect different analog and digital sensors for complex automation and higher efficiency.c

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 sensor data.

Garage door control
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.

Heat your water to an optimal temperature
Meet your daily needs without wasting anything!
Shelly PM relays allow you to determine the optimal amount of energy needed to heat the water in your instantaneous water heater.
When used in conjunction with a temperature sensor, Shelly relays can automatically shut off the instantaneous water heater when the optimum temperature is reached.

Keep the heat in the house
Used in conjunction with an LDR (photoresistor), the Shelly Plus Add-on can cause the Shelly Plus 2PM to close the blinds when direct sunlight shines on your windows and heats up the room.
This way, the air conditioner doesn't have to compensate for the heat by using more electricity, saving energy.
And don't worry about losing the pleasant daylight!
As soon as the sun changes its location, the blinds will automatically open again.

An awning that follows the weather
Motorized outdoor awnings provide your guests with comfortable shade on sunny days.
However, a strong, uncontrolled wind can damage them irreparably. 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.
In addition, the Shelly Plus Add-on with a rain sensor can cause Shelly Plus 2PM to open the awning in time to protect your guests.
