Retrofit any existing wall switch into a smart scene controller - no rewiring or renovations, by installing Shelly i4 Gen4 behind the switch and using single/multi-clicks (and holds) across up to four inputs to trigger Scenes and complex automations that control other Shelly devices or fire HTTP/MQTT/Webhook actions (e.g., one press for “Movie Night” to dim lights, close blinds, and mute the TV), while keeping fast local control and adding multi-protocol flexibility (Wi-Fi, Zigbee, Bluetooth, Matter) with voice assistant support.
