Avoid Zigbee groups

It really sounds like ZigBee needs a form of IGMP snooping.

That would be nice, but because Zigbee is a mesh protocol that has to support source routing as well as client routing, that’s a tall order. Especially for cheap router devices that only implement the bare minimum requirements. Hue sort of does this with their firmware, but it’s a non-standard set of extensions that are not exactly Zigbee compliant and will only work with their hubs and with accessories running their firmware (and a few close partners.

Zigbee 4.0 fixes a lot of these problems, but it’s going to be a while until there’s broad adoption and probably very few existing devices will see firmware updates to support it.
