I am surprised that there is no fix for this yet.

Shouldn't it be simple to allow for channel hopping, similar to a mesh Wi-Fi network?

This is the #1 reason I am staying away from the Zigbee lineup right now, the first two I put in worked fine, they were small dedicated home theaters which worked fine.

I almost lost my shirt on a larger multi-zone project where distributed audio was controlled from several roaming T2-C's, luckily, the customer ended up not really needing to move the zone remote controls as much as he thought he would initially.

I am hoping there is some sort of solution in the works, it seems awfully cheap to have a customer re-booting remotes on a complex and expensive control system.
