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.
