Why Shelly i3

Shelly i3 has no relays but is small enough to be installed virtually anywhere and shows the status of 3 inputs. The device is in one of the switches and can command other connected Shelly relays, sensors, or HTTP, MQTT or CoAP controlled devices. Opportunities are endless through discrete commands on the home network or scenes in the cloud.

For Developers

Shelly i3 comes with a programming/debug header which can be used to flash alternative firmware on the device. It has an ESP8266 inside, with 4MB flash chip. A USB-to-UART adapter is needed as well as a reliable 3.3V with at least 350 mA drive capability.
