Shelly Plus 1 UL is a WiFi smart relay switch designed for safe and reliable control of lights, garage doors, irrigation systems, HVAC equipment, and other electrical appliances.
This 1-channel 15A smart relay features dry contacts, allowing you to control low-voltage and high-voltage circuits independently. That makes it ideal for garage door openers, alarm panels, thermostats, and other control applications.
Powered by the ESP32 processor, it delivers fast response time, improved API performance, and enhanced security with MQTT, TLS, and custom certificate support.
Small enough to fit behind standard US wall switches, outlets, or inside electrical boxes, Shelly Plus 1 UL enables retrofit smart automation without replacing existing hardware.
No hub required. Connect directly to your WiFi network and manage remotely via app, voice assistants, or automation platforms.
