The Shelly Plus 2PM WiFi 2-channel relay, sold in a set of four, is a compact solution for the intelligent control of electrical devices in smart homes. The modules are specifically designed for automating roller shutters, lighting, and small motor loads, while also offering integrated power monitoring. The combination of switching and measurement functions makes the system suitable for both comfort and energy optimization applications. The 2-channel architecture allows for the independent control of two circuits per module. In roller shutter mode, the device can be used for targeted raising and lowering movements, with precise control logic ensuring motor operation. This enables flexible integration into existing electrical installations without major structural modifications. A key technical feature is the integrated power and energy monitoring. This allows for the real-time recording and analysis of current consumption values. This function is particularly relevant for analyzing energy efficiency in the home and identifying peak loads from connected devices. The WiFi-based control enables direct integration into smart home systems without the need for additional gateways. Configuration is done via mobile apps or compatible platforms, making it easy to create automations and schedules. Voice control via common assistance systems is also typically possible. The compact design allows for installation in flush-mounted boxes, enabling discreet integration into existing electrical installations. This is particularly advantageous for retrofits, as no visible changes to the living environment are required. The devices are designed for continuous operation and offer stable switching performance within the specified load limits. Internal temperature and load monitoring contributes to operational reliability and protects against overload or thermal stress. Installation requires basic electrical engineering knowledge and should be carried out professionally, as the device is directly integrated into the building's electrical system. Once correctly set up, however, it offers a highly flexible and scalable automation solution. Overall, this is a versatile and functional smart home relay that is particularly impressive due to its combination of control, energy monitoring, and compact integration.
