Accessories & Sensors. Everything that isn’t a relay or dimmer: temperature, humidity, water leak, motion, door/window and gas sensors; the Shelly Pill modular sensor system and its add-ons; wall switches, frames and touchscreen displays for physical control; current-clamp and CT accessories for energy monitoring; BLU-series Bluetooth buttons, remotes and the BLU Gateway; and the TRV radiator valve. Sensors are split across WiFi, Bluetooth (BLU) and Z-Wave (Wave) connectivity — check which hub or app ecosystem you’re already running before choosing, since these aren’t interchangeable at the protocol level.
A battery-powered Bluetooth sensor that detects when a door or window opens or closes, and also measures tilt angle and ambient light. Runs on a single CR2032 cell for up to 5 years and connects via the BTHome protocol, so it can be built into automation scenarios and scenes.
