Shelly Dimmer Gen3 – Smart WiFi dimmer for Lighting (Compatible no neutral required)
The Shelly Dimmer Gen3 is a smart module developed to precisely adjust lighting intensity, even in installations that do not have a neutral wire. Equipped with the new processor ESP-Shelly-C3 with 8 MB, it offers greater speed, stability, integration capacity, and support for advanced features.
It can be controlled through WiFi, local commands, Web interface, or remotely via cloud. Pairing via Bluetooth simplifies the initial configuration, and compatibility with platforms such as Home Assistant, Alexa and MQTT allows for complete integration into any home automation ecosystem.
The device supports schedules, night mode, energy monitoring (with neutral connected), and works with various types of dimmable light bulbs. The compact size and support for existing switches make the Dimmer Gen3 a versatile solution for modernizing lighting with comfort and efficiency.
