Shelly Wave 1 Mini – Z-Wave Smart Relay (Dry Contact, 8A)
Overview
Shelly Wave 1 Mini is a compact Z-Wave smart relay with dry (potential-free) contacts, designed for in-wall installations where space is limited. It allows on/off control of a connected circuit (AC or DC) while keeping the relay output electrically isolated, which is useful for controlling devices via a contact input rather than switching mains directly.
Key Features
• Single-channel relay with dry (potential-free) contacts
• Switches AC loads up to 8 A at 240 V or DC loads up to 5 A at 30 V
• Z-Wave mesh device that can extend the network (repeater function)
• Z-Wave 800 Series (S800) chipset for improved performance and reliability
• SmartStart support for fast, secure inclusion
• Supports Z-Wave associations for direct device-to-device control (hub still required for setup)
• Extremely low standby power consumption (< 0.3 W)
• OTA firmware updates via compatible Z-Wave hubs
• Security 2 Authenticated (S2) encryption
• Built-in overheating protection
