Description
SHELLY-25UL is a compact WiFi-operated dual-independent smart relay and two switch inputs for a device or roller control. Shelly 2.5 UL can control two different loads/lights and can be used for open/close/up/down for shades or for motor control with variable positioning. Shelly 2.5 can be powered by a wide range of low or high voltages.
The switch (dry contact) inputs can be used to monitor a contact closure, or connected to a switch to control the relay outputs.
Shelly 2.5 UL has a built-in microprocessor and web server to allow it to be controlled and monitored by a smartphone, tablet, or home automation system. It can be used on its own with free apps using the Shelly Cloud or integrated with a smart home system.
The built-in processor allows it to support scenes when combined with other Shelly devices, as well as built-in scheduling based on time of day or sunrise/sunset.
Shelly devices work with Google Home and Alexa voice assistants.
Shelly works on its own or with MQTT, SmartThings, Home Assistant, HomeSeer, Homey, Hubitat, OpenHAB, and REST integration.
