Aggregated specification data identifies the Oelffow unit as a 1P smart relay utilizing a 90A mechanical latching relay for circuit control. Technical specifications indicate the integration of a BL0942 energy IC, providing +/- 1% accuracy for voltage and current telemetry. The device is powered by a Tuya TYWE3S chipset (ESP8266), facilitating 2.4GHz Wi-Fi connectivity for remote scheduling and energy monitoring via the SmartLife application.
Performance metrics confirm that while the device is marketed for home safety, it lacks the thermal-magnetic trip bar required for UL 489 certification. Material analysis of the internal components reveals a risk of contact welding when the relay is toggled under high inductive loads, such as air conditioning compressors. The compact 18mm width allows for installation on standard 35mm DIN-rails, making it a modular solution for secondary monitoring in DIY sub-panels or lighting arrays.
Functional feature highlights include:
- Modes of operation: Remote Control, Local Timer Sync, Real-Time Energy Monitoring
The Smart WiFi Mini Circuit Breaker for Home Safety is an effective tool for secondary load tracking and automation. For mission-critical primary circuit protection, the Leviton 2nd Gen Smart Circuit Breaker with Remote is the technically appropriate choice due to its certified safety architecture.
Within the broader smart circuit breakers category, this unit serves as a digital relay for non-critical applications.
