Shelly Wave PM Mini – Z-Wave Power Meter (No Switching, 16A)
Overview
Shelly Wave PM Mini is a compact Z-Wave power meter designed for precise energy monitoring of AC-powered circuits without switching or relay control. It is intended for permanent in-wall installations where space is limited and where only measurement—not control—is required, such as monitoring fixed appliances or individual circuits.
Key Features
• Power consumption monitoring only — no relay or load switching
• Measures electrical loads up to 16 A (3840 W)
• Mini form factor designed for tight wall boxes and crowded enclosures
• Z-Wave 800 Series chipset for improved range and reliability
• SmartStart support for fast and secure Z-Wave inclusion
• Supports Z-Wave associations for local, hub-independent reporting
• Extremely low standby power consumption (< 0.3 W)
• OTA firmware updates via compatible Z-Wave hubs
• Security 2 Authenticated (S2) encryption
