Technical Specifications and Applications

The Shelly 2PM Gen4 operates on 24V DC or 110-240V AC voltage. It has two switch input terminals, which are optional to use. The device automatically measures power consumption on both channels, which can be monitored via the Shelly Smart Control app and utilized in automation scenarios. Applications include:

• Control of two lighting circuits
• Management of sockets

Local Operation – No Gateway Required

Shelly WiFi devices feature a built-in web server that ensures continuous operation even without an internet connection.
