The EU Battery Directive refers to the laws and regulations issued by the European Union regarding batteries and accumulators, with the main aim of reducing the environmental impact of batteries, especially in terms of the disposal and recycling of waste batteries. The Battery Directive 2013/56/EU is the replacement regulation proposed by the EU for the Battery Directive 2006/66/EC. Batteries may contain heavy metals such as mercury, lead, cadmium, and acidic or alkaline electrolyte solutions, which, if not properly handled, can cause varying degrees of harm to human health and the ecological environment. Therefore, the collection and post-treatment of waste batteries are very important. On September 26, 2006, the European Parliament and the Council of the European Union issued Directive 2006/66/EC on batteries and accumulators and waste batteries and accumulators, which includes policies on the restriction of hazardous substances in batteries, the recycling and treatment of waste batteries, and their regeneration. On December 10, 2013, the Official Journal of the European Union officially published the amending Directive 2013/56/EU to the Battery Directive 2006/66/EC, revising several exemption clauses in the new Battery Directive. The EU Battery Directive includes requirements for the limitation of hazardous substances in batteries, labeling requirements, and recycling rate requirements.

"Zero-crossing detection is the execution of relay action (closing/opening) at the AC zero-crossing point, which can effectively avoid the generation of electric sparks during relay contact action, especially in high-power load circuits, and extend the relay life. The zero-crossing detection signal is provided by the hardware circuit to the module, which is an edge signal (both rising and falling edges are effective, one zero-crossing signal for each half-wave of the sine wave) and can adapt to the current power supply frequency (50Hz or 60Hz). The zero-crossing action delay time t is configured by the user on the platform based on the actual test results of the relay action time (or the manufacturer's reference value).".

In order to address the events encountered by users in the electric charge metering function of electrical products, we provide all-in-one solutions for handling overcurrent, overvoltage, and undervoltage events. Overcurrent: For products that have been set with an overcurrent point (unit: mA). When the sensed current is greater than the set value, the relay will be disconnected, and the fault will be reported. Undervoltage: For products that have been set with an undervoltage point (unit: V). When the sensed voltage is less than the set value, the relay will be disconnected, and the fault will be reported. Overvoltage: For products that have been set with an overvoltage point (unit: V). When the sensed voltage is greater than the set value, the relay will be disconnected, and the fault will be reported.
HA, short for Home Automation, is a transmission protocol launched by Connectivity Standards Alliance for the smart home industry. It defines and standardizes data transmission commands and fields in detail for smart home devices and defines device functions, device linkage, event triggering, remote communication, communication modes for each function, and more. Origin and development of Zigbee HA The first Zigbee specification was published in 2004, the second in 2006, and the third in 2007. Zigbee-2007 Specification defines two feature sets: Zigbee and Zigbee Pro. HA is based on Zigbee Pro and is one of the multiple application layer specifications for different fields. The application layers at that time included: Zigbee HA (Zigbee Home Automation) → Smart Home Zigbee LL (Zigbee Light Link) → Smart Lighting Zignee HC (Zigbee Health Care) → Smart Healthcare Zigbee RS (Zigbee Retail Services) → Smart Retail Zigbee BA (Zigbee Building Automation) → Smart Building Zigbee TS (Zigbee Telecommunication Services) → Smart Communication Service The more commonly used ones are Zigbee HA and Zigbee LL. However, the protocols of different application layers are not interconnected. Even if the same Zigbee HA protocol is used, each smart home manufacturer will customize the Zigbee HA for their own needs, resulting in the independence of different manufacturers' products. The Connectivity Standards Alliance organizes institutions specifically for Zigbee HA certification in pursuit of HA standardization, also known as Zigbee HA1.2 certification. In 2016, the Alliance launched Zigbee 3.0, which uses the Zigbee Pro standard network layer protocol, implementing the interconnection of protocols between different application layers, further standardizing the Zigbee protocols, and representing a major step forward towards smart home interconnection.
