## Description

The Shelly Pro 3 is a LAN, WiFi and Bluetooth smart switch with 3 separate channels, engineered to be mounted on the DIN rail in the breaker box. It can automate heating/cooling or lighting systems in any space and includes robust safety features to protect against overvoltage or overheating.

The Shelly Pro 3, similar to its 1 and 2 channel counterparts the Shelly Pro 1 and 2, is a part of Shelly's Pro series and so is designed to be installed on the DIN rail directly in the breaker box. The Shelly Pro 3 features dry contacts for wide applicability, and its three separate channels widens the level of customisation even further, being able to operate a bi-directional motor and light fixture with complete precision, or maintaining temperature or humidity when paired with a sensor.
Like the rest of Shelly's range, the Pro 3 is fully customisable with 200+ smart home integrations and Voice assistants like Amazon Alexa or Google Home, and can be integrated into wider scenes or routines with many Shelly devices working in tandem for complete control over the space.
