[eWeLink CUBE] Zigbee Broadcast to grouped devices

For those with multiple lamps in the same room, you’ve probably experienced the “popcorn effect,” where some Zigbee lamps fail to respond simultaneously.

To prevent this, I use Zigbee Grouping, a feature available on platforms like Zigbee2MQTT, Hubitat, ZHA, and others.

Zigbee Grouping allows multicast messages to be sent to multiple devices simultaneously, eliminating the popcorn effect and reducing the risk of network overload.

Please, add the possibility to Group multiple devices with Zigbee broadcast messages.

The grouping feature was more like an application-level thing for now. It supports grouping device controls across devices connected via different protocols. For instance, you can group on/off actions of Matter lights, eWeLink-supported Wi-Fi lights, and Zigbee lights.

However we will explore how to better support such native grouping features in future versions.

Thx for the feedback.
