You have any 2.4 GHz WiFi problems? In theory there is a problem, and I know a dude with a lot of ZigBee and a lot of 2.4GHz problems, but without going over with work equipment and spending some time doing work for free, I can’t be sure it’s ZigBee. It’s just my best guess.
I hope it continues to be a non issue for you. Without you having to take any measures. Just saying it can be an issue. Search “zigbee 2.4ghz wifi interference” if you don’t believe me.
