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 small accessory required for no-neutral installations of the Shelly 1L, Shelly Dimmer 2 and Shelly Dimmer Gen3, allowing low-wattage loads such as LED bulbs to switch and dim correctly without flickering or failing to turn off fully.
The Shelly Flood is a battery-powered Wi-Fi leak sensor with a built-in temperature sensor, described as the world's first Wi-Fi flood and rain sensor with temperature measurement. It runs on a single CR123A battery for up to 18 months and alerts you the moment water is detected on the floor.
A photoelectric smart smoke alarm designed to catch slow, smouldering fires before they take hold, sending instant phone notifications and letting you build safety scenes around an alert. Runs on a CR123A/CR17335 battery for up to 5 years and connects over WiFi and Bluetooth with MQTT support.
The Shelly Gas CNG is a mains-powered Wi-Fi gas detector with a sensitive module specifically for compressed natural gas leaks, giving a flashing LED and sound alarm when triggered. It includes a jack output for connecting an automatic shut-off valve manipulator, so a detected leak can cut gas supply as well as alert you.
A Wi-Fi energy meter for monitoring the consumption of individual appliances, circuits or a whole home, including solar generation, with two independent measurement channels up to 120A each. It also includes built-in contactor control functionality and stores 365 days of energy history on the device.
The Shelly BLU Motion is a battery-powered PIR sensor that reports motion instantly over Bluetooth using the BTHome protocol, with a built-in light sensor for brightness-based automations. It runs up to 5 years on a single CR2477 battery and needs a gateway — a Shelly BLU Gateway or any mains-powered Plus, Pro or Gen3 device — to reach the Shelly app.
The Shelly Button Add-on is a surface-mounted enclosure that houses a compatible Shelly relay or dimmer, letting you add smart control to lights or fans without opening walls or fitting a new back box. It comes with pre-installed, colour-coded wiring and works with a wide range of Shelly Gen1, Plus, Gen3, Gen4, and Mini devices.
This is a Shelly EM energy meter bundled with two 120A current clamps, for individually monitoring the consumption of appliances, circuits, or a whole home including solar generation. It's a Wi-Fi energy meter with contactor control functionality, storing 365 days of built-in energy history, in the larger-clamp configuration for higher-current circuits.
The Shelly H&T Gen3 is a battery-powered temperature and humidity sensor with a low-power e-paper display and built-in clock, designed for wall or surface mounting. It needs no separate hub, connecting over Wi-Fi and MQTT, and runs for around a year on 4 x AA batteries, with USB-C available for faster setup.
This is a 3-pack of Shelly BLU TRV smart thermostatic radiator valves, sold with a Shelly BLU Gateway Gen3 that adds Wi-Fi connectivity to each valve's Bluetooth and Zigbee links. Each valve adjusts hot water flow through a radiator to hit a set temperature, controllable via the rotary encoder, app, or a weekly schedule, on 2 x AA batteries.
The Shelly BLU RC Button 4 ZB is a wire-free remote with four physical buttons and multi-click support, giving up to 16 customisable commands from single, double, triple, and long presses. It connects via Bluetooth and Zigbee, mounts with built-in magnets or a 3M adhesive patch, and runs up to two years on a single CR2032 battery.
The DS18B20 is a temperature probe designed to add temperature sensing to compatible Shelly relays that support an external sensor addon. It plugs into the Shelly 1/1PM temperature addon or a Shelly Uni, letting you trigger automations or logging based on measured temperature rather than relying on the relay alone.
The Shelly BLU Remote Control ZB is a handheld remote with four independent channels for controlling relays, dimmers, and blinds without an app. It connects via both Bluetooth and Zigbee to Shelly Pro, Plus, Gen3, and Gen4 devices, and includes a precision scroller for dimming plus gesture control via a built-in accelerometer.
A pack of 10 low-profile cable brackets for tidily securing sensor cables, leak detection cables, or other low-voltage wiring up to 4.5mm diameter along walls, floors, and baseboards. Each has pre-applied adhesive for tool-free fitting plus an optional screw point for more permanent installations in tight or awkward spots.
A rugged, IP54-rated smart button in a mocha finish, with dual Bluetooth and Zigbee connectivity for instant control of lights, appliances, blinds or scenes. Supports single, double, triple click and long-press for four distinct actions, responds in under a second, and runs up to 2 years on one CR2032 battery.
A Z-Wave contact sensor that detects opening and closing of doors, windows or safety gates, and also measures tilt angle for openings that tilt or turn, via a built-in light sensor. Runs up to 2 years on one CR2032 battery in a compact housing suited to discreet frame mounting.
