  #### 💡 最佳实践方案：把卡片改为“Changelog（更新日志）”

  建议你不要删除这个入口，但改变它的定位。把 `Product Updates` 改名为 Changelog 或 What's New，并采取以下策略：

  1. 卡片内容做成“时间轴”： 全局卡片只记录大版本或跨产品线的改进（比如：*2026-Q1: 全线设备 Zigbee 协议优化*）。
  2. 做成“链接集合”： 全局卡片内部不需要写具体细节，而是通过列表链接到各个 `Product Document` 里的具体 `Release Notes`。

<summary><strong>Do you offer ODM collaboration?</strong> <code>[SPM/SDM/SRS Products]</code></summary>

Yes, we offer ODM collaboration for most of our **Electrical Monitoring Devices**. We are glad to stay behind the scenes if an ODM business model can accelerate the digitalization of power distribution systems and make smart energy management accessible to more people.

**For hardware product brand customers**, our ODM program is primarily focused on:

1. **Electrical installation product brands** — promoting energy efficiency management within power distribution systems of homes, buildings, and infrastructure.
2. **Residential clean energy equipment brands** — including solar inverter, battery storage, and EV charger manufacturers whose products typically require local automation integration with energy meters for real-time control and optimization.
3. **Smart home product brands** — looking to expand their product line beyond home automation into energy management, extending their ecosystem from smart living to smart energy.

**For system integrators and total solution providers**, we understand your business is largely project-driven. For smaller projects, a standard off-the-shelf solution is likely the most practical path. However, for large-scale projects with significant volume and scope, we are fully committed to providing dedicated ODM support to help you deliver a tailored, competitive solution.

We can further provide **customer-specific design and customization** for ODM partners who have an ambitious and feasible plan to grow together.
