8-Channel Smart Light Controller (LoRaWAN) with Power Metering – Milesight WS558-LN

The Milesight WS558 is a professional 8-channel smart light controller designed for installations that need reliable switching plus clear visibility into energy usage. It controls up to 8 independent circuits and supports remote control and scheduled automation, making it a solid fit for building lighting zones, retrofits, and distributed sites where running control wiring is costly.

A key advantage is built-in electrical measurement: the WS558 measures VAC voltage, mA current, power factor, power (W), and energy consumption (kWh). This supports energy reporting, usage optimization, and early detection of abnormal loads. To improve operational safety, it also provides overcurrent protection and alarms, helping prevent outages and reducing maintenance overhead.

Connectivity is handled via LoRaWAN and Milesight D2D (device-to-device), enabling both standard LoRaWAN network server deployments and local D2D scenarios. Configuration can be done via NFC, USB-C, or downlink, while switching is available both locally via the front buttons and remotely. A power-off memory function is included to support predictable behavior after power loss.

Typical real-world uses:

Commercial buildings: lighting schedules, zone control, and energy visibility per area

Warehouses & industrial sites: load monitoring and safer switching with overcurrent alarms

Smart city lighting zones: centralized control over distributed lighting circuits

Retrofit projects: add control and metering without heavy new cabling
