Shelly Plus i4 4 channel smart control unit opt. Plus Addon & DS18B20 Temp Sensor

Article description Shelly Plus i4:

Smart WiFi 4 channel control device

The Shelly Plus i4 has no relays, but is small enough to be installed virtually anywhere and displays the status of 4 inputs. The device is located in one of the switches and can control other connected Shelly relays, sensors or HTTP, MQTT or CoAP controlled devices.

Through discrete commands in the home network or through scenes in the cloud, the possibilities are endless. The Shelly Plus i4 allows you to integrate your existing (light) switches into the smart home. There are four separate inputs available for switches or buttons.

No HUB required! The Shelly Plus i4 connects to your existing WiFi network and allows actions to be triggered as soon as a connected switch is pressed.

4 AC inputs! - Shelly Plus i4 has four inputs for every situation. You can create scenes in the Shelly Cloud app and control them all.

Multi-click support! - Up to 12 possible actions. Check the lights, close the blinds and open the door. Operate any Shelly device you want and control any scenes you want.

Extremely fast processor - ESP32

Java script support for individual and complex scenarios

Bluetooth - Quickly and easily add devices via a Bluetooth connection with the Shelly Cloud app

Compatible with Android, iOS, Amazon Alexa, Google Assistant and home automation servers with MQTT, CoAP and REST API.

Article description Shelly Plus Addon:

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.

Article description DS18B20 Sensor:

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

There are 5 cable lengths to choose from.
