Relays & Switches. The core Shelly line: WiFi/Zigbee/Bluetooth relays that fit behind an existing wall switch, socket, or in a back box, adding smart on/off and (on the PM/EM models) power-metering control to lights, sockets and appliances you already have — no new wiring required, no hub needed for the WiFi and Bluetooth models. Choose by channel count (1, 2 or more circuits), whether you need power metering (PM/EM suffix), and connectivity (plain WiFi, Gen3/Gen4 with Zigbee, or Qubino Wave for Z-Wave networks). Most retrofit directly onto existing 5-6A lighting circuits or 13-16A ring mains.

The Shelly LAN Switch is a DIN-rail mountable 5-port Ethernet switch designed to fit inside a breaker box alongside Pro-series devices, sharing their form factor. It takes 110-230V power directly on its terminals rather than needing a separate adapter, so a single LAN cable into the box can serve multiple wired Shelly Pro devices.
Shelly Plus Uni is a low-voltage automation and monitoring module for retrofitting older appliances and metering equipment. With two digital and one analogue input, it supports 1-Wire temperature sensors and pulse-count reading from energy, gas or water meters, as well as most Arduino-style sensors.
