Relay Wifi Pro Shelly Gen3 with potential-free contact set
Shelly
Relay Wifi Pro Shelly Gen3 with potential-free contact set
Art. no.: 1302003
Shelly 1 Gen3 is a WiFi-controlled 1-channel 16A relay with potential-free contact, intended for mounting behind switches, wall sockets or lamp sockets. It enables easy control and automation of lighting, garage doors, irrigation systems, bathroom fans and basically all existing electrical appliances Thanks to the compact design, it fits in most wall and ceiling boxes.

Shelly 1 Gen3 is easily configured and controlled via the Shelly Smart Control app or your preferred smart home or smart building system. Shelly devices work 100% locally and only require a local network to operate. Shelly can be used alone in the Shelly Smart Control app or with over 200 partner systems such as Google Home, Amazon Alexa, Home Assistant, Samsung SmartThings, Athom Homey and many more.

Shelly 1 Gen3 has many uses. It can be powered by 12V DC, 24-48V DC or 110-230V AC. With the potential-free contact, it is possible to operate the device with low voltage while connecting a 230V device to the relay or vice versa. The device has a simple switch input which is optional to use and which is fully programmable. This makes Shelly 1 Gen3 useful for many purposes, such as:
•Light control
•Control of bathroom fans
•Underfloor heating control
•Garage door control
•Management of irrigation systems
•SG-Ready heat pump control

All Shelly WiFi devices have a built-in web server, which means you get a wealth of features that always work. The built-in web server means that Shelly has built-in memory and therefore remembers sunrise, sunset, schedules and more, even when the network goes down. Relays and dimmers work like normal rocker relays and can therefore be used with your usual switches - even without internet. All inputs and outputs are fully programmable and only require local wifi to communicate between devices. However, we recommend having an active internet connection as it opens up even more features.

•5 VDC (stabilized, via +5 VDC and GND)

Examples of use
•Heating: add up to five DS18B20 temperature sensors and measure your supply and return temperature.
•Temperature and humidity: Use a DHT22 sensor to measure temperature and humidity.
•Wind: with an anemometer, your awning can automatically retract when it starts to blow.
•Analog voltage measurement: Create automations based on voltage measurement from 0-30V.
•Alarm clock: make your old alarm clock smart.
•Fan hood: make your hood smart and start automatic ventilation when the stove is lit.
•Consumption measurement: use the pulse meter to monitor water, electricity and gas consumption, flow measurement, etc. It is possible to define pulses per minute as well as what is measured.

Connection
Shelly Plus Uni can be connected to the Internet or the local network via 2.4 GHz WiFi. In addition, the device has built-in Bluetooth, like the rest of the Pro and Plus devices, which means it can also be used as a gateway for Shelly's battery-powered Bluetooth devices.

All Shelly devices work locally without connecting to the Shelly Cloud, but it is recommended to enable this for easy data storage and increased functionality. Devices can also communicate via MQTT, HTTP and WebSocket. All support TLS.
Relay 1L Gen3 WiFi
Shelly
Relay 1L Gen3 WiFi
Art. no.: 1302109
Shelly 1L Gen3 is a WiFi controlled 1-channel relay that works without a neutral conductor and is particularly suitable for controlling lighting where there is no neutral conductor behind the switch.

Shelly 1L Gen3 has a built-in 1.2A relay and can control lighting up to 275W. It is powered by 220-240V AC. Please note that the included bypass should be installed in parallel with the load and that a minimum load of 5W is required.

The device has two switch inputs that are optional to use and are fully programmable.

Shelly 1L Gen3 is easily installed and controlled via the Shelly Smart Control app or your preferred smart home system. Shelly devices work 100% locally and only require a local network to function. Shelly can be used individually in the Shelly Smart Control app or together with over 200 partner systems such as Google Home, Apple HomeKit, Amazon Alexa, Home Assistant, Samsung SmartThings, Athom Homey and many more. The device is also Matter certified.

All Shelly WiFi devices have a built-in web server, which means you get access to a variety of functions that always work, regardless of whether you have an active internet connection or not. You also don't need a gateway and can therefore get started with just one Shelly device. The built-in web server means that Shelly has built-in memory and therefore remembers sunrise, sunset, schedules, etc., even if the network goes down. Relays and dimmers work like regular impulse relays and can therefore be used with your regular switches - even without internet. All inputs and outputs are fully programmable and only require local WiFi to communicate between devices. However, we recommend having an active internet connection, as it opens up even more functions.

Relay 2L Gen3 WiFI
Art. no.: 1302151
Shelly 2L Gen3 is a WiFi-controlled 2-channel relay that works without a neutral conductor and is particularly suitable for controlling lighting where there is no neutral conductor behind the switch.

Shelly 2L Gen3 has two built-in relays:
- O1 (Output 1): 1.2A relay - primarily intended for 230V incandescent lamps and LED light sources without a transformer.
- O2 (Output 2): 3A relay - can also be used for low-voltage lighting, fluorescent lamps and fans.

Both relays can be controlled individually via the switch and the Shelly Smart Control app. The device is powered by 220-240V AC. Please note that the included bypass should be installed in parallel with the load and that a minimum load of 5W is required. However, the bypass does not need to be installed when using fluorescent lamps.

Shelly 2L Gen3 is easily installed and controlled via the Shelly Smart Control app or your preferred smart home systems. Shelly devices work 100% locally and only require a local network to function. Shelly can be used individually in the Shelly Smart Control app or together with over 200 partner systems such as Google Home, Apple HomeKit, Amazon Alexa, Home Assistant, Samsung SmartThings, Athom Homey and many more. The device is also Matter certified.

Works locally - no gateway needed
All Shelly WiFi devices have a built-in web server, which means you get access to a variety of functions that always work, regardless of whether you have an active internet connection or not. You also don't need a gateway and can therefore get started with just a single Shelly device. The built-in web server means that Shelly has built-in memory and therefore remembers sunrise, sunset, schedules, etc., even if the network goes down. Relays and dimmers work like regular impulse relays and can therefore be used with your regular switches - even without the internet. All inputs and outputs are fully programmable and only require local WiFi to communicate between devices.
