英国采购需求：电力表，单相电力钳形表，智能电力表，涂鸦电力表，WiFi电能表，WiFi电能监控器

I'm interested in sourcing a device that has a design similar to the one I've seen. Ideally, it would support both 4G connectivity and battery power options. Flexibility is crucial, as I need the ability to program the device for data delivery to a specific endpoint I define, such as a web location or API. In addition, I'd like to know about the customization options available and any specific features that might enhance its functionality. It's also important to understand the potential for integration with other systems. Please provide details on the product specifications, pricing, minimum order quantities, and lead times for delivery. Looking forward to your response!
