Shelly Dimmer Gen3

The new and long-awaited Shelly Dimmer Gen3 is here. Now, Shelly's package is really up-to-date to make all your lighting smart. Additionally, Shelly has announced that around the beginning of 2025, the Gen3 devices will be made Matter compatible via a firmware update. This will allow you to connect with multiple Matter compatible platforms, such as Apple HomeKit.

What's New?

The Shelly Dimmer Gen3 is the successor to the Dimmer 2, with the main differences being;

- The Shelly Dimmer Gen3 features the faster ESP32-C3 chip with 8MB of memory, prepared for the upcoming Matter update (especially interesting for Apple HomeKit users)
- It has Bluetooth onboard for easier connection with your home WiFi and also works as a Bluetooth gateway for the Shelly BLU Sensors.
- Now supports Scripting
- Screw terminal now supports up to 2.5mm²
- Better WiFi antenna and other component upgrades
- Works without a blue neutral wire, with Shelly Bypass for lamps under 20W (be aware of the jumper when used with the Bypass!)

Shelly Dimmer Gen3

The Shelly Dimmer Gen3 is a smart dimmer module for behind your wall switch that controls lighting systems and integrates them with smart home networks. Turn on/off and dim your lights wirelessly with your smartphone from anywhere in the world. And the great thing is, you can still connect a wall switch. We recommend choosing a double pulse switch that you connect to S1 (Input 1) and S2 (Input 2) of the dimmer, where you use S1 to turn the dimmer "on" or "off" (click) and dim up (hold), and with S2 to turn the dimmer "on" or "off" (click) and dim down (hold). Or go for the Jung Multi-pulse switch which clicks up and down.

NOTE: the Shelly Dimmer Gen3 does not work behind your existing (rotary) dimmer or with smart lights!
Please read the manual, especially regarding the different way of wiring without a blue neutral wire, and always calibrate the dimmer after connecting or changing the lamp.

Easily create smart scenes (scenarios) and set timers in the free app for your home automation. For example, automatically turn on your lights at sunset or automatically dim your lights for the night between 11:00 PM - 6:00 AM. Voice control with Siri (requires Siri shortcuts or Homebridge), Google Assistant, or Amazon Alexa is also possible; "Hey Google, set the table lamp to 40%".

The Dimmer has the option to set lighting schedules, night mode for dimmed light at night, min/max dim settings, adjustable dimming speed for a wall switch. Dimming via a wall switch requires a pulse switch with a 'make-contact' feature. Clicking turns it on/off, and holding dims. Also works as a WiFi repeater, Bluetooth Gateway, supports scripting, webhooks, MQTT, WebSocket, HTTPS, UDP, TLS, and custom certificates. Also supports KNXnet/IP communication.

Shelly has its own free app that lets you easily and cheaply set up a Smart Home system without the cost of a Gateway/Hub. The open-source nature ensures you can integrate the Shelly Dimmer with almost any home automation system. The Shelly Dimmer Gen3 has a Shelly ESP32 C3 chip with 8MB of flash memory built-in. The 8MB provides more memory for updates and potential Matter firmware updates in the future. It also has Bluetooth for easy connection to your home WiFi, over-temperature protection, enhanced security with MQTT + SSL, MQTT with Cloud, and scripting. Additionally, the terminals (screw connections) have been improved and now support up to 2.5mm², which was sometimes a problem with the older version and the 2.5mm² wire behind the wall switch.
