Shelly Pro 1 DIN-Rail Mounted Smart Switch with Dry Contacts

Shelly Pro 1 is a DIN-rail single-channel smart relay with potential-free dry contacts for professional and domestic distribution-board installations. It can switch an independent circuit without electrically tying the load to the relay’s supply, making it useful for lighting, heating controls, irrigation, contactors and other compatible equipment.
Ethernet, Wi-Fi and Bluetooth connectivity are built in, together with scripting, schedules, webhooks, MQTT and an embedded web interface. The DIN-rail format, local-network operation and dry-contact output make it suitable where centralised, serviceable control is preferred over in-wall modules.
