Smart switch Sonoff HS082321 2-pole Wi‑Fi with remote control and timer

SONOFF Smart 2-channel switch HS082321 is a DIN-rail mounted Wi‑Fi device for remote control and energy monitoring of household electrical appliances. The switch supports two independent channels, works on 2.4 GHz Wi‑Fi and is compatible with the eWeLink mobile app, Amazon Alexa and Google Assistant. It provides built-in metering of energy consumption, voltage, current and power factor, and includes protections against overload, short circuit, overvoltage and leakage.

Advantages

The HS082321 combines remote control, scheduling and real-time energy metering in a compact DIN-rail form factor for easy installation. It records consumption data and allows you to set unit energy price and thresholds for power, current or voltage so loads are automatically switched off when limits are exceeded. The device supports app control from anywhere, voice assistants and download of consumption reports. LED indicators and a manual on/off button simplify local operation.

Suitable for

• Remote switching and scheduling of lighting circuits
• Control and monitoring of water heaters, air conditioners and large appliances
• Energy management for household circuits and basic automation scenarios
• DIN-rail electrical panels in apartments, houses or small commercial installations

How to use

Install the HS082321 on a 35×7.5 mm DIN rail inside the distribution cabinet following local electrical codes. Connect the two output channels to the loads and supply with AC 100–230 V. Set up Wi‑Fi (2.4 GHz) and pair the switch with the eWeLink app on Android or iOS to enable remote control, scheduling and metering. Configure unit energy price and thresholds in the app to enable automatic shutdown when limits are reached. Use the on-device button and LED indicators for basic local control and status monitoring.

Usage recommendations

The device is intended for indoor installation in electrical cabinets; ensure connection and commissioning are performed by a qualified electrician. Use the recommended ambient temperature range (-5 °C to +40 °C) for accurate metering and reliable operation. Do not connect loads that exceed the specified current limits and follow the app settings to configure protective thresholds.
