Shelly's professional 1-circuit relay can communicate with Wi-Fi, wired network (LAN), and Bluetooth connection, and is a solution suitable for both home automation of apartments and professional automation of more serious commercial buildings (stores, condominiums, shops, etc.). The PRO product line is primarily intended by Shelly for the automation of newly constructed buildings, where building automation can be solved simply and professionally with Shelly Pro devices, without additional cabling, with relays placed next to the circuit breakers in the electrical cabinet.

- LAN, Wi-Fi and Bluetooth support
- Simultaneous LAN and WiFi are supported
- Simple pairing with the Shelly Cloud app via Bluetooth
- It also has two switch inputs
- 1 output, 16A max. performance.
- Suitable for voltage-free switching, direct current and alternating current switching
- DIN rail compatible
- LAN, Wi-Fi and Bluetooth: It is capable of Wi-Fi and LAN connection at the same time, and pairing with the phone is easier than ever before, using a Bluetooth connection
- In the case of star-point wiring, it is also an ideal solution for the cost-effective automation of newly built apartments and commercial properties
- 1 circuit relay: with 1 controlled output, max. 16 It can switch the power
- Voltage-free switching is also supported: the relay circuit is independent of the power supply provided for the operation of the relay, suitable for DC and AC switching, or even for voltage-free switching (dry contact)
- Can be operated from 110V-240V AC
- Wire cross-sections: switched circuit ("I" and "O"): 2.5mm2, the other inputs (feed for operation, switch inputs): 1.5mm
- Super fast ESP32 processor: fast operation, fast notifications
- Suitable for controlling many devices: Lighting, for automating household appliances, for controlling sprinkler systems, pool mechanics, for automating heating and many other devices. Devices requiring voltage-free switching are especially popular, e.g. boiler, door opener motor and motorized garage door.
- Increased safety: Made of fire-resistant (V-0) material and the device is equipped with overheating protection
- Increased IT security: MQTT and WSS support, TLS and custom certificates are also supported
- No hub / central unit required: Connect directly to the WiFi router to access the Internet and the factory cloud so that it can be controlled as easily as possible from the Shelly Cloud App
- It can be integrated with almost everything: it can be controlled not only with cloud voice assistants (Alexa, Google Home), but also with many commercial and open source home automation systems
