SOLT Tuya WiFi Smart DIN Rail Circuit Breaker with Energy Monitoring and Voltage Protection

The Soltree SOLT series brings remote control, energy monitoring, and electrical protection together in a single DIN rail circuit breaker that works with the Tuya and Smart Life app ecosystem. All three models connect to standard 2.4GHz WiFi and are compatible with Amazon Alexa and Google Assistant for voice control — making them a practical upgrade for smart home installations, rental property management, and commercial power automation without replacing existing distribution hardware.

The SOLT-OF is the entry-level remote control model, adding WiFi on/off switching, timer scheduling, and relay last-status memory to any circuit. With over 100,000 rated mechanical operations, it is built for long-term, high-cycle applications such as lighting circuits, pump controls, and non-critical load automation where simple remote access is the primary requirement.

The SOLT-M adds real-time energy monitoring to the remote control foundation — tracking voltage, current, active power, and cumulative kWh consumption through the app. Historical usage data and smart scheduling make it well suited for home energy management, solar system load control, and rental property sub-metering where understanding consumption patterns is as important as remote switching.

The SOLT-MV is the most capable model, combining all SOLT-M metering functions with 4-in-1 electrical protection: over-voltage, under-voltage, over-current, and over-power, each with user-configurable trip thresholds set directly in the app. The auto-trip function protects sensitive electronics and high-power appliances from grid anomalies. Important notes: wiring must use L+N (top entry), not L+L. Not compatible with Home Assistant. 2.4GHz WiFi only; 5GHz not supported.
