Shelly Plus AddOn modul k Shelly 2PM Gen3

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

It can be used with up to five DS18B20 sensors (temperature) or one DHT22 sensor (temperature and humidity).

It has analog and digital inputs.

Compatible with most Arduino sensors.

Compatible with Shelly Plus 1/1PM, Shelly Plus 2PM, Shelly Plus i4/i4DC.

Why Shelly Plus Add-on?

Shelly Plus Add-on is a galvanically isolated sensor interface for all Shelly Plus series relays. Use it to measure temperature and humidity using its 1-Wire-enabled terminals or connect various analog and digital sensors for complex automation and higher efficiency.

Widely compatible

Shelly Plus Add-on is compatible with most Arduino sensors! Use its digital or analog inputs to measure the desired parameters and create complex automation scenes based on sensor data.

Endless App Uses

Garage Door Location - You can connect a reed sensor to the Shelly Plus Add-on digital sensor and monitor the status of your garage door. This way, you will always know if it is open or closed when you are away and take appropriate action.

Water Heating - With the Shelly Plus add-on and two DS18B20 sensors, you can easily measure the exact temperature inside the aquarium, as well as the temperature in the room. Based on this data, you can maintain a comfortable and healthy environment for your pets. In addition, you can connect a liquid level sensor to the add-on and always make sure that the water level is at the optimal level.

Control your lights based on luminosity - Together with an LDR (photoresistor), the Shelly Plus Addon can trigger the Shelly Plus 2PM blinds when it is too dark in the room and it is still daytime. Additionally, when the light is low, the Shelly Plus Add-on can trigger the Shelly Plus 1 to turn on the lights at the right time.

Weather-controlled awning - Outdoor motorized awnings offer pleasant shade for your guests on sunny days. However, strong, unpredictable winds can damage them beyond repair. Combined with a wind sensor connected to the Shelly Plus Add-on, the Shelly Plus 2PM can automatically close the outdoor awning to protect it from the wind. Additionally, the Shelly Plus Add-on with rain sensor can trigger the Shelly Plus 2PM to open the awning just in time.

Water only when needed - Having a beautiful garden is no easy task, and automating your irrigation system can save you time and optimize your costs. Together with the soil moisture sensor, the Shelly Plus Add-on can trigger the Shelly Plus 1 to irrigate only when needed, always skipping rainy days.

Motion-controlled lights - The 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 a room, the light will stay on for as long as you need it.
