R730 channel utilization?

[b8]

I recently purchased a R730 to integrate into my SOHO setting, replacing one of my three existing R720s which have performed flawlessly. 
I've been seeing really high channel utilization figures so am trying to understand root cause. Ive disconnected all wifi devices other than my MacBook to run some diagnostics software and Ruckus vSZ-E and still see 20% utilization (sometimes peaking at closer to 50%). 
I have 3 SSIDs on 5Ghz and 4 on 2.4Ghz (IoT subnet)
Im curious if this is expected behavior with the AX chipset or a config error by a somewhat new to Ruckus user. 



Controller: 5.1.1.0.598
Control plane: 5.1.1.0.405
AP firmware: 5.1.1.0.624


thanks in advance

Hi RF0V1K,

Nice share, Good to know that these devices would interfere with WiFi.
