Measure and control with precision

Shelly Plus Add-on is a galvanically isolated sensor interface for all Shelly Plus relays.

 Use it to measure temperature and humidity using its 1-Wire terminals, or connect various

analog and digital sensors for complex automation and higher efficiency.

Motion-controlled lights

Shelly Plus Add-on can also be connected to a PIR sensor to light up rooms

that you occasionally use around the house. This way, when you enter the room,

the light will come on for as long as you need it to.

Irrigation only when needed

Having a beautiful garden is not an 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 trigger Shelly Plus 1 to turn on the irrigation only

when necessary, always skipping the rainy days.

An awning that follows the weather

Outdoor motorized awnings offer pleasant shade for your guests on sunny days. However,

 a strong, unexcepted wind can damage them beyond repair. By combining it with a wind

sensor connected to the Shelly Plus AddOn, Shelly Plus 2PM can automatically close the

outside awning to protect them from the wind. Additionally, Shelly Plus Add-on with a rain

 sensor can trigger Shelly Plus 2PM to open the awning just in time to protect your guests.
