Shelly Plus AddOn Sensor Extension for Plus Devices opt. max. 5x DS18B20

Article description:

Addon for Shelly Plus series

This addon is compatible with Shelly Plus 1, Shelly Plus 1PM, Shelly Plus 2PM, Shelly Plus i4, Shelly Plus i4DC

Can be used with up to five DS18B20 sensors or one DHT22 sensor

Has an analogue and a digital input

Depending on the measured temperatures, the previously created scenes can carry out certain actions.

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 automation and greater efficiency.

Highly Compatible - The Shelly Plus add-on is compatible with most Arduino sensors! Use the digital or analog inputs to measure the desired parameters and create complex automation scenes based on the 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 always know whether it is open or closed and can react accordingly.

Endless possible uses

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 always know whether it is open or closed and can react accordingly.

Heat the water to an optimal temperature - cover your daily needs without wasting anything! With the Shelly PM relays (optional) you can determine the optimal energy requirement for heating the water in your water heater. In conjunction with a temperature sensor, the Shelly relays can automatically switch off the water heater when the optimal temperature is reached.

Keep the heat in - Together with an LDR (photoresistor), the Shelly Plus add-on can cause the Shelly Plus 2PM (optional) to close the blinds when direct sunlight shines on your windows and heats up the room. In this way, the air conditioner does not have to compensate for the heat through increased power consumption and therefore saves energy. And don't worry about losing the pleasant daylight! As soon as the sun changes location, the blinds automatically open again.

An awning that follows the weather - Motorized outdoor awnings provide pleasant shade on sunny days. However, a strong, uncontrolled wind can damage them beyond repair. By combining with a wind sensor connected to the Shelly Plus add-on, Shelly Plus 2PM (optional) can automatically close the outdoor awning to protect it from wind. Additionally, the Shelly Plus add-on with a rain sensor can cause the Shelly Plus 2PM (optional) to open the awning in time to protect you.

Water only when needed - 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 cause the Shelly Plus 1 (optional) to turn on watering only when needed and skip the rainy days.

Motion Controlled Lights - Shelly Plus Add-on can also be connected to a motion detector to illuminate rooms you occasionally use in the house. When you enter the room, the light stays on for as long as you need it.

DS18B20 temperature sensor

The probe uses a new DS18B20 temperature sensor chip. Each pin of the chip is separated by a shrink tube to prevent short circuits. This version is waterproof and suitable for any indoor or outdoor use.

Suitable for your Shelly temperature sensor or Arduino, Raspberry Pi projects.

The sensor supports a wide temperature range from -55 °C to 125 °C
