Option to indicate presence of Zigbee devices

I have a Zigbee hub with a couple of dozen devices attached to it, and at certain times, the performance is quite poor.

From what I understand, Zigbee channel #26 (2.4ghz) interferes with Wifi channel #11, and I am in the process of looking to see if this is an issue in my environment. Looking at my Orbi configuration, I can manually choose a channel or leave it at Auto. However, excluding only channel #11 seems that it would be particularly handy in this instance.

Alternatively, if the router were aware that a Zigbee network was present, the channel selection algorithm could take that into consideration.
