Smart home and IoT devices built around Shelly: relays that fit behind an existing switch or in a distribution board, dimmers for lighting circuits, energy meters that measure a single circuit or a whole board, and door, motion, temperature and humidity sensors. Most devices connect over Wi-Fi, with Bluetooth for setup and for the battery-powered sensors.

Shelly works with Home Assistant, Google Home and Amazon Alexa without a proprietary hub, exposes a local API and MQTT for anyone who prefers to script their own automations, and keeps working on the local network when the internet does not. Pick a relay by the load it switches and the space behind the switch plate, and check whether the circuit has a neutral wire before ordering — the product page states what each device needs.

The range also includes compact solar panels for keeping sensors, cameras and small loads topped up; for inverters, batteries and full backup systems see our solar, inverters and backup power range. Everything is priced in rand with VAT included and ships nationwide.
